Round Hole Patterns

The rule of thumb for perforating is that the hole diametershould not be less than the thickness of the material. The closer to a 1-to-1 ratio, the higher the probability of tool failureand the greater the precautions necessary to avoid it.

Modifications can be made in certain instances at additionalcosts. For stainless steels and similar higher strength materials,it is preferable to specify at least three thickness gauges thinnerthan hole diameter.

The same general rule applies to bar width. The bar widthshould be greater than material thickness because of theincreased number of punches and, therefore, increased perfora-tion tonnage. The bar width can be adjusted at increased costs.

Revolving Screens

Shown below are drawings of typical sizes of hexago-nal, round and square openings (perforated or woven)that are equivalent with regard to size of materialscreened. As shown, Hexcreen provides the accuracyof round openings. And since Hexcreen has the great-est open area of the three types, it passes through more material. Specific values are as follows:

NON HEAT-TREATED PLATECSA-QUALITY STEEL is the standard materialfor Cross screen plate and exceeds industryspecifications. It was developed in cooperationwith leading steel producers to specific chemicaland physical properties, extremely close tolerances, and uniform quality. Rockwell hard-ness rating of 85 B. Rolled and treated fortoughness, strength and freedom from brittle-ness, CSA steel contains a minimum Carbon .30alloyed with other abrasion-resisting elements.

. . . metallurgical, engineering and productiondepartments have combined efforts in the devel-opment of a genuine hardened-and-temperedperforated screen plate, NS-280. It has a mini-mum hardness rating of 280 Brinnell throughoutits entire thickness.This provides lower cost per ton of screenedmaterial. Additional savings are realized fromincreased production due to fewer screenchanges and reduced maintenance costs. NS-280 is available in all perforation types.

“Consider the advantages of perforated screen plate!”l Screen Life - Special alloyed steel provides wear

resistance to outlast any oil-tempered wire cloth.l Less Down Time - This means fewer changeouts

during production which are extremely costly.l Ease of Maintenance - Perforated screens will not

stretch so no re-tensioning is required during service life of the screen section.

l Screen Frame Protection - Blanked areas are designed and engineered into perforated to protect screen support frame.

l Greater Choice - Round, hexagon, square or slotted; straight or staggered centers; precise, flexible configu-ration and virtually infinite pattern possibilities.

l Wider Material Thickness Range - Wide range of thickness for each opening size. Bar width and plate thickness can be separately specified to attain desired open space while maintaining increased wear life.

l Excellent Screening Efficiency - Perforations are staggered in direction of flow. The percent of open area of Perforated Screen Plate equals or exceeds the percent open area in wire cloth in many cases.

l Resistance to Plugging - Screen Plate features cleanwalled, conical, closely and uniformly spaced perfora-tion. This results in a minimum of binding, because material is always passing through a progressively larger opening.

l Maintenance of Sizing Accuracy - Since Screen Plate is a single unit, there is no wire movement which would interfere with sizing accuracy as the screen wears through.

l Greater Bulk/Less Breakage - Greater effective cross sectional area compared to wire cloth screen. This translates into greater screen life with no open area reduction.

l Fewer Wear Causes - Perforated Screen Plate and wire cloth wear from material passing over and throughthe screen. Wire cloth also wears from wires rubbing each other at junction points.

Std. Tolerances for Stock Size or Machine Run Sheets

Balance Shearing - (LWD only. Expanded to SWD dimension) providesmatching sections for continuous catwalk or flooring applications. Closeddiamonds SWD, cut with either open or closed diamonds to obtain orderedlength LWD.Bond - apex of the opening where strands intersect.Camber - measured placing straight edge on concave side of sheet parallelto LWD touching both ends of the sheet. Maximum distance from edge ofexpanded metal to straight edge is the camber. (A sheet may have a widthtolerance of ± 0" and still have a camber.) See Diagram B

SWD 1/16" per foot of lengthLWD Standard—1/16" per foot of lengthFlat—3/32" per foot of length

Centerline Shearing - finished piece symmetrical, about a row of diamondsat center of piece—open diamonds both SWD and LWD.Deburring - removal of burrs and sharp edges by wire brushing 9"-72"SWD, 50"-150" LWD. Not all styles will be deburred.Design Size - actual design measured from a point on the bond to a corresponding point on the adjacent bond.Electro-galvanized - a zinc finish for sheets to help provide weather resistance.Flattened Expanded Metal - metal which has been passed through flatten-ing rolls (cold rolled) turning the strands and bonds down to provide a flatsurface. The flattening operation reduces the thickness (gauge) of themetal and stretches the pattern or piece. Abbreviation “FXM”Flattening - limited to 72" maximum one dimension. Flattened sheet thick-ness shall be ±10% of the published thickness.Hot Dip Galvanizing - a protective coating of zinc; may have a roughuneven appearance. Patterns smaller than 1/4" do not lend themselves tohot dip galvanizing.Leveling - a plane of the sheet leveled without flattening strands or bonds.LWD - “long way of design” nominal dimension (center to center of bond).LWO - “long way of opening”. See diagram.Manufactured to size - closed diamonds on all sides. Size tolerances arethe same as for stock size sheets. Unless otherwise specified, material willbe produced to a plus side of the tolerance.Mill Finish - Plain Steel—expanded metal is lightly oiled and should becleaned before finishing. The most common cleaning method is an acid orsolvent batch with a water rinse. Aluminum—clean with a non-etchingchemical or detergent, then rinse and dry thoroughly. A wax or non-waxbase cleaner can be used.Opening Size - actual opening size of diamond.Out of Square - (measured using 90º angle) Expanded metal sheets are notperfectly square as manufactured. Stock size sheets and machine runsheets will be produced to the following tolerances:

SWD 1/16" per foot of width LWD 1/16" per foot of length(Sheet must be re-squared by shearing on all sides for perfect squareness)—See Diagram COverall Thickness - thickness from top to bottom of expanded sheet.Standard Expanded Metal - expanded metal as it comes off the machine.Standard Thickness - gauge of thickness of metal expanded.Strand Width - amount of metal fed under dies to produce one strand.SWD - “short way of design” nominal dimension (center to center of bond).SWO - “short way of opening”. See diagram.

HEAVY WELD PANEL WIDTHS

EXPLANATORY NOTES FOR TABLES HWC/HWD/HWE

Symbols and weights shown for gratingshaving cross bars spaced at 4" centers.For gratings having cross bars at 2" cen-ters add suffix -2 to item number. Increasetabulated weight to 1.1# for the 1/4" HWbearing bar sizes and 2# for the 3/8" HWbearing bar sizes.

Supplementary cross bars can be installed in pairs on the underside of gratings with depthsof 3" or more, when specified. These additionalbars provide extra load distribution and lateralstability to the carrying members. For shortspans, one set located at mid-point. For greaterspans, two or three pairs depending upon spacing of supports.

Where gratings are subjected to extremelyheavy loading conditions, or rolling loads at 90degrees to bearing bars, further assurance ofsatisfactory performance can be obtained bytrim banding the ends of panels. Such bandbars are usually 1/4" thick and 1/2" less than thedepth of the grating and welded flush with thetop of the grating. Banding must be specified.

Note: The carrying capacity of a piece of grating subjected to a concentrated load over only a portion of its width is determined by the stiffness of both the bearing bars & the cross bars, and therefore varies with the type of grating used. To determine carrying capacity of gratings subject to such loadings, please call us for information.

Our molded fiberglass is a strong mesh grating panel which allows efficient on-site cutting to minimize grating waste. Molded in one piece with a plain concave non-slip walking surface, it is the chemical resistant flooring choice for many industrial applications.Load bearing bars in both directions allow for use without continuous side support.Molded fiberglass grating is significantly lighter in weight than metallic gratings. The high resin content (65%)

provides long maintenance free performance. Molded Stair Tread Covers are available.

Combining corrosion resistance, long life and a maintenance free design, our fiberglass pultruded T-bar gratingis superior to conventional metals. This advanced grating is also lightweight (half that of steel) and easy to fabri-cate, making it less expensive to install. In fact, the savings on labor and equipment often make the total installedcost comparable to that of steel grating. Combining its low cost of installation with maintenance free long life, fiber-glass grating offers a life cycle cost that is significantly lower than that of steel.

NOTE: When 100 poundsper square foot uniformload placed upon a 43"simple span, it will pro-duce a deflection of 1/4"at midspan.

NOTE: Since fiberglass grating will not provide lateral stiffness for stairs, struts and bracingshould be provided on bottom flange of stringers. .25" deflection is recommended as the maxi-mum to provide pedestrian comfort, which can be exceeded at the discretion of the engineer.

Grating Installation - Install grating in accordancewith manufacturer’s recommendations and shopdrawings. Position grating sections flat andsquare with ends bearing min. 1-1/2" on support-ing structure. Keep grating sections at least 1/4"away from vertical steel sections and 1/2" fromconcrete walls. Allow clearance at joints betweensections of max. 1/4" at side channels and 3/8" atends. Band random cut ends and diagonal or cir-cular cut exposed edges with a min. 1/8" thick barwelded at contact points.Grating Attachment - Attach grating to supportswithout warp or deflection as follows:a. Single plank application - Secure plank endsto supporting members at every point of contact.Use GRATE-LOCK Anchoring Devices.b. Multiple plank application - Secure plankends to supporting members at every point of con-tact and intermediate grating sections with at leastone attachment at each end of plank on alternatesides. For added rigidity, attach side channels ofadjacent plank together (at mid-point of span).c. Welded attachment - Secure side channels tosupports by fusion welding with 1/8" fillet welds 1"long. Weld adjacent planks together with 1/8" filletwelds 1" long, 24" o.c. staggered top and bottom.d. Clamp and bolt attachment - Secure interme-diate planks to supports using proper length hold-down clamps.

Every year industrial accidents—falls, tripping over debris, slipping onwet or greasy surfaces—cost millionsof dollars in lost manhours and pro-duction. By reducing accidents,insurance costs can frequently bedecreased. GRIP STRUT® SafetyGrating helps reduce accident ratesby providing a safer walking-workingsurface than any other available grat-ing product. Its serrated surface givesmaximum slip protection and perform-ance under practically all conditionsand in every direction.

In addition to safety, the resilientsurface of GRIP STRUT cushions theimpact of footfalls thereby lesseningworker fatigue and increasing his effi-ciency. GRIP STRUT is your bestsafety buy. These cost-cutting andproduction-improving advantagesspell out why.Safer, serrated surface

These non-slip GRIP STRUT sur-faces are ideal for inside or outsidelocations where mud, ice, snow, oiland detergents can create hazardouswalking conditions. Openings aresmall enough to catch most fallingtools and other dangerous objects.Maintenance-free open design

Permits quick drainage of fluids,chips, grease and mud. Any ice accu-mulation shears easily under normalfoot pressure. Open design allowsconvenient access for cleaning.High load capacity, long life

High strength-to-weight perform-ance is achieved through depth ofsection and structural design. Bridgedstruts with integral side channels forma plank that can support loads with

minimum transverse and longitudinaldeflection. There are no rivets orpressure joints to break or loosen.This sturdy construction provides theadvantages of heavy load carryingcapacity with minimal deflection,rugged durability with longer-lastingperformance.

With 4-1/2 inch high side channels,GRIP STRUT Walkways meet OSHArequirements for toeboards on elevat-ed structures.Fast installation

Light, easy-to-handle planks makeinstallation simpler and quicker. Theycan be handled by one man. Mostsections are rapidly bolted, clampedor welded into place, easily field cutat virtually any angle, or fabricated toadapt to field conditions.Economical to install, use

In addition to low material cost andnominal erection cost, GRIP STRUTalso saves with its long-lasting, rust-resisting materials. Standard mill-gal-vanized finish resists corrosion. High-strength aluminum and Types 304and 316L stainless steel are availableto provide maximum corrosion resist-ance. Black unpainted steel availablefor installations requiring hot dip gal-vanized finish after fabrication. Theselightweight but brawny panels permitsubstantial reduction in structuralsteel requirements.Versatile in application

A variety of standard widths andchannel heights combine with numer-ous non-standard shapes and sizes.One piece construction—no welds orrivets to fail—minimizes need forplant fabrication.

How to Read Load TablesThe following information refers to Regular or Heavy Duty GRIpSTRUT® Safety Grating or GRATE-LOCK® Grating hereinafterreferred to as “grating”.To select size of grating, determine load, clear span and

deflection requirements. Having this information select fromthe appropriate load tables for regular GRIP STRUT, HeavyDuty GRIP STRUT or GRATE-LOCK Grating to find theappropriate plank to meet job requirements.FOR EXAMpLE: If you require a clear span of 4'-0", concen-trated load of 300 lbs. at 0.25" max. deflection and have chosen regular GRIP STRUT, you would verify the following:8-Diamond GRIP STRUT, 18-3/4" wide, 2-1/2" height, 12-gauge steel will carry a load of 416 lbs. at a 0.18"deflection. This is one size to do the job. Other sizes willcarry more load if necessary. For more economicalselection, choose the greatest width that will support theload consistent with job requirements and choose deeperchannels rather that heavier steel gauges.Grating will generally carry similar concentrated loads,

tabulated in pounds at mid-span, for a given span, materialgauge and height, regardless of width. The uniform loadtables are tabulated in lb./sq. ft., which accounts for the differ-ence in load capacity shown for various widths. Deflection isin inches.To ensure the safety of the tabulated loads, two aspects of

grating strength must be considered. The first considerationis transverse bending in the grating surface, which is referredto as “strut flexure.” This occurs when the grating is loadedwith either a uniform load or a mid-width concentrated load,and the “struts” (grating surface) deflect relative to the sidechannels. To determine the allowable strut loads, samples of

each plank material and thickness were tested for each plankwidth. (see Fig. 3). The data resulting from these tests wasused to prepare “strut loading” tables for regular GRIP STRUTand Heavy Duty GRIP STRUT and “rung loading” tables forGRATE-LOCK Grating, which give allowable loads and deflec-tions considering strut flexure only. These allowable strut andrung loads have been incorporated in the Product Selection/Design Tables for regular GRIP STRUT and GRATE-LOCKGrating (not Heavy Duty GRIP STRUT).The second aspect of the grating strength is channel flex-

ure. This occurs when the channels at mid-span of the grat-ing deflect relative to support points. To verify the perfor-mance of the side channels, samples were loaded with concentrated and uniform loads at different spans. To approximate the most severe condition, there were no attachments between the channels and the supports. Incases where spans are shorter, channels deeper and grating wider, strut flexure becomes more critical.With the exception of 8- and 10-Diamond regular GRIP

STRUT, it can be assumed that both side channels and allwidths of GRATE-LOCK and Heavy Duty GRIP STRUT effec-tively support the concentrated load, and the grating surfacedeflection is negligible. Based upon these assumptions, thefollowing values found in the load tables have been deter-mined: If grating surface deflection should be consideredwhen selecting a product to meet a particular specification,then the deflection of the mid-width of the grating, relative tothe side channels, can be calculated using both the data in the Strut Loading Tables and the Load/DeflectionConversion formula.All load tables show maximum loads, based upon actual

load tests.

In the elastic range, deflection is proportional to the applied load for both uniform and con-centrated loads. This relationship can be used to determine the deflection that any load which is less than the allowable load will produce, as shown in Example A. Also, if desired, the load which will produce a specified deflection can also be determined if the load is in the elastic range as illustrated in Example B.EXAMpLE AWhat deflection will a 300 lb. concentrated load produce on a plank (catalog number 103012) spanning 5' 0"? See page 33 for item103012 at a span = 5'0" C = 480 lb. D = D@300 lb. = 0.26"

roof performance—protects membrane, optimizesroof performance by:

(1) saving the roof from abuse of walking and equip-ment (with walkways, abuse never sets foot onyour roof again)

(2) minimizing abrasion, walkway pressures on mem-brane (large rubber pads distribute support-standloads)

(3) relieving membrane thermal stresses (no fasten-ers, low bearing stress permit membrane movement)

(4) maximizing direct, free-flow drainage (elevatedplanks, open supports, waffle pads)

(5) preserving membrane integrity (leaks often start at fastener or other membrane penetrations)

Versatility—designed for all roofing systems: built-up(BUR), single-ply (SPR), inverted, and spray-on

Here's the “safety first” way to re-do worn and unsafefloors and stairs. Resurface with GRIP STRUTReconditioning Material (RM). GRIP STRUT is theonly product that gives 500 wall-to-wall teeth per sq. ft.Down-turned edges allow grating to lie flat and secureover existing flooring. Consult McNICHOLS for Product Specifications. RM products available onspecial order in standard materials and sizes.

NOTE: Photo shows viewfrom underneath assembly.

Recommended clearanceSTEEL: 1/4" minimum is recom-mended at perimeter and 3/8"maximum at end joints.Maximum between panels is 1/4". 1/8" is generally used.CONCRETE: Concrete formdeflection calls for slightly greaterperimeter clearance. 1/2" is rec-ommended. (Maximum betweenpanels 1/4"). Bearing SurfacesRecommended minimum bearing1-1/2". Surfaces supporting GRIP STRUT must be smoothand level to insure that adjoiningsections provide a safe, evenwalking surface.Permanent InstallationGRIP STRUT is easily welded tosupports for permanent installa-tions. Channels are quickly weld-ed together between supports toprovide uniform deflection inadjacent panels.For welded attachment, secureside channels to supports byfusion welding with 1/8" fillet

Heavy-Duty GriP Strutmay be painted, hot-dip galvanized-after-fabrication, anodized, plated, plas-tic-coated or specially finished.Low life-cycle cost

Material cost is low, erection cost nominal. Corrosion-resisting finishesprovide long service life. Brawny, lightweight planks, walkways and stairtreads permit substantial reduction in supporting structural materials.Fast, Simple installation

Sections are easily field-cut; connections are rapidly made with bolts,clamps or welding.Compliance with regulatory codes/standards/tested performance

Walkways meet OSHA toeboard requirements for elevated structures.tests prove that falls can be reduced by the safe surface of Heavy-DutyGriP Strut Safety Grating.

PERF-O GRIP® Grating helps to cut accident rates byproviding a safer walking-working surface. The unique surface of large debossed holes and perforated buttonsprovides maximum slip protection. In addition to provid-ing safety, the resilient surface of PERF-O GRIP® Gratingcushions the impact of footfalls thereby lessening workerfatigue and increasing efficiency. High load capacity, long life, and high strength to

weight performance is achieved through depth of sectionand structural design. Formed plank with integral sidechannels support loads with minimum transverse and lon-gitudinal deflection. There are no rivets or pressure jointsto breakor loosen.Large Open Area (38% of surface area depending on

product size) permits free flow of air, heat and light.Often eliminates need for sprinklers under catwalks andplatforms.

WHAT IS GRIP TIGHT? Aluminum oxidegrit is bonded to a metal base using ametal bonding agent. This metal andabrasive grit composite provides a non-sparking, non-corrosive surface thatmeans surer footing under slippery condi-tions. GRIP TIGHT offers superior coefficient of friction for slip resistance under wet or dry conditions, low maintenance, andhigh strength to weight ratio. Surface canbe specified on either a steel on steel, alu-minum on aluminum, aluminum on steel,or aluminum on galvanized steel base. Agalvanized finish can be applied over theentire surface when a steel bonding agentis specified. The grit surface comes in 4 grades of slipresistant coating. McNICHOLS

products offer the most aggressive. All grades/profiles of the grit surfaceexceed the minimum .60 C.O.F. requiredby many municipalities.GRIP TIGHT Floor Plate finishes are thoseof the natural color of the bonding material itself. However, the steel basematerial may be supplied either painted orgalvanized. SPECIAL ORDERGRIP TIGHT® Ladder Rungs are available“solid” with grit surface or as covers (see photos). Rungs are steel on steel.GRIP TIGHT® Type C-3E Nosing is suit-able for poured or precast constructionand is available in 20' lengths. Providedwith 2" wide Integral Aluminum Anchor.Please visit mcnichols.com for more information on our GRIP TIGHT Products.

This type is recommended when the “Gridsteel®” is to be spacedfrom the steel shell to allow room for thick insulationbetween the steel shell and the armored surface. The slots in the “Gridsteel®” bars permit passage ofthe castable which forms a key between adjacentcells. “Gridsteel®” is available with lance if required.Standard is without lance.Maximum bond between the “Gridsteel®” cells andcement is insured by the long wide slots in ALL facesof each Hex agon. “Gridsteel®” takes abrasion, vibration and shock loads in stride. As the gridspreads the load, the hexagon steel edge enhancesthe wearing qualities of the surface. This edge peensover as the surface wears, thus increasing the area of the surface steel while the flatness of the wholearea is maintained.“Gridsteel®” supports the lining and preventsslump. It retards erosion, corrosion, cracking, blistering, pitting or collapse, and so “lengthensthe life of the lining, and greatly reduces the frequency of costly shut downs!”

To determine the maximum deflection for the limited allowable load, divide the deflection coefficient by the plate thickness. EXAMPLE: Deflection for a 1/2" thick plate, 3'-0" span, at 593 lbs. per sq. foot = 0.149 (deflection coefficient) ÷ 0.50" (platethickness) = .298".

INSECT SCREEN

1. Vibrator screens need time to seat into place. Install newscreen under partial tension without a load and allow it tovibrate for a brief period of time to seat properly. Then tightenfully to proper tension. Loose installation will cause prematurebreakage.

2. Bucker up or crown bar rubber strips should be checked everytime you change screens. Remember—the rubber wears fromthe bottom on the rails and wear is not always visible.

3. Check the size of pieces being installed. Also make surescreens have hook strips parallel. Tension uniformly to main-tain screens in parallel.

Lock Crimp - Provides accurate screen openingsfor life of the screen. Used when plain weave willnot hold accurate openings.Plain Weave - Openings are square and wiresizes are the same in both directions. Each warpwire passes alternately over and under shutewires at right angles both directions. Standardweave used for wire cloth. (Sometimes calledDouble Crimp).Intercrimp - Used in larger openings with lightwire to provide greater stability, tightness ofweave and maximum rigidity.Flat Top Weave - Flat surface improves flow ofmaterials over screen panels by reducing friction.Provides more wearing surface than otherweaves. Locking weave assures accurate openings to provide uniform grating and screening efficiency.Triple Shute Weave - Ideal for working with sticky or wet material that normally plugs squareor oblong opening screens. Weave holds wiresecurely in place yet permits wires to vibrateslightly to keep openings free and at peak efficiency.

CRIMPS & WEAVES

(flat surface-one side only)

VIBRATING SCREENS

Slotted Screens - On Slotted Screens, the direction of theslot should be specified so as to be unmistakable. Usually thebest way is to specify “long slots parallel to 49" dimension” asin Example 1 below. In those few cases where the length andOB dimensions are the same, it is necessary to tell the direc-tion of long slots in relation to the length. Example 1 “longslots at right angles to the length;” and Example 2 “long slotsparallel to the length.”

Some shaker screens require a special fabrication to meet allOEM specifications. Check your screens and note them on your order.

l Squarel Slottedl Woven

l Stainless Steell Plain Steell Formed or Plain Edge

Screens for sizing and straining can be furnished byMcNICHOLS with any style of edge preparation or hookstrip, ready for installation into any type equipment.Often the edges of screens woven of heavier than .250" arefabricated to hook on to the vibrating frame, similar to StylesM-1 and M-4. However, most screens made of .250" andlighter wire have a hook strip supporting the edges similar toM-2, M-3, OR M-5. Edge treatment, whether simply bent hooksor hook strips, should be specified when screens are ordered.Absolutely square hook strips enable screens to be kept undergreater, more uniform tension. This protects them against distortion and excessive vibration which causes metal fatigueand breakage.FOR SPECIAL EDGE STYLES NOT SHOWN, PLEASE CALL US.

AppLICATIONS

Weldmesh® is one of the most versatile of all Wire Cloth products. Weldmesh® is awelded steel wire mesh manufactured frombright drawn mild steel wire, electricallywelded at all intersections. It is producedwith a copper washed finish and can be hotdip galvanized after manufacture. Becauseit’s welded, it can be cut or bent to theshape required without the wires fallingapart and forms its own selvage when cutflush.

Weldmesh® is available in panels in a variety of wire diameters and meshes up to 3".

The physical properties of the wires usedare rigidly controlled to produce a weldedmesh which has a maximum weld strength.Please call us for product assistance!

Please see diagram at top left in the How to Order section. The Diagram showsa finished edge on all four sides of a standard panel.
