Technica l advantages

1 Good anti-skid properties through

high-grip surfaces. The anti-skid effect is tested

by BIA. See table on page 5.

2 Lengths up to 6,000 and 12,000 mm:

this permits a wide bearing span and reduces the

cost of steel structures.

3 Lumped loads act directly on the surface. To

allow these concentrated loads to be supported,

a joint bearing width (bm) of the grating surface

forms in the lengthwise direction, which is related

to the width of the grating B and the size of the

load surface.

The equation is: bm = a + 0.625 x B.

(B = grating width: a = length of load surface in lengthwise

direction of grating)

4 The unperforated edge assumes the func-

tion of an upper boom for the static cross-section.

5 The inward edge fold forms the lower boom

for the static cross-section.

6 The material thickness (2.0/2.5/3.0/3.5 mm) is

taken into account in calculating the load-bearing

capacity.

7 Widths depending on surface

(see standard dimensions).

8 The load-bearing height (H)

(40/50/75/100 mm), e.g. increasing from 40 to 50

or from 50 to 75 mm results in a greater increase in

load-bearing capacity than increasing the material

thickness from 2.0 to 3.0 mm (which also raises

the amount of material required and the dead

weight of the gratings by 50%).

A ”light” element, on the other hand, increases

the useful load within the static framework as a

whole and simplifies handling and installation.

Notes:

All drawing dimensions are in mm:

H = height D = sheet thickness

L = length b = unperforated edge

B = width

The dimensions stated may vary slightly for

technical reasons.

Continuous support (load increase)

If the grating rests on several supports, the max-

imum load can be increased by approx. 37%.

It is assumed that the load area acts over the

whole grating width B. If the load surface is not

applied over the whole width, the figures given in

the table ”Lump load” must not be exceeded.

Load increase

1. If the grating rests on several supports (con-

tinuous support), the maximum single load per

grating can be increased by 23%.

2. If three gratings are bolted together in such a

way that the load is exerted on the centre

grating only, the maximum load figures in the

table ”Single load” may be doubled.

Lump loads are the most frequently occurring type

of load. They are caused by small contact surfaces

(e.g. the human foot or the wheel of a vehicle)

acting on the centre of the grating width. The size

of the loads and load-application area can be

determined according to DIN 1055, sheet 3 or

DIN 1072.

Loads with small contact surfaces act directly on

the surface profiling of the grating. To allow these

locally exerted loads to be supported, a joint bear-

ing width of the grating surface forms in the

lengthwise direction which is related to the width

of the grating B and the size of the load surface.

The equation is: bm = a2 + 0.625 x B.

Where a2 is the length of load surface in length-

wise direction of grating, and bm the joint

bearing width of the grating surface.

The static cross-sectional data are also contained in theunperforated edge (b).

Single load

Lumped load

The profiled sheet gratings are calculated for the

elastic properties of the material. Dimensioning is

either against the yield strength of the material,

i.e. against the maximum permissible stress, or

against a maximum deflection.

In the load tables, the elastic deflection of the

support ”profiled sheet grating” is limited to

L/200. L is the bearing span. The deflection is

limited to a figure of 10 mm.

If higher deflection values are permitted, the load

tables must be recalculated.

In the case of adjacent gratings, the deflection of

the individual loaded grating must not be greater

than 4 mm. If the deflection is greater than

4 mm, the gratings must be bolted together in

such a way that the difference between the

deflection of the loaded grating and that of its

neighbours is less than 4 mm. The following types

of load may occur:

a) Evenly distributed load in kN/m2 acting

vertically on the surface of the grating.

b) Vertically acting single load in kN which is

exerted over the entire width of the grating

and may be distributed over an area of

B x 0.2 m. The single load must be exerted in

the most unfavourable position.

c) With floors supporting traffic, single loads occur

(e.g. wheel pressure). The size of the loads and

the load-application area are given in

DIN 1055, sheet 3 or DIN 1072.

Graepel-Stabil SSafety at work, even under extreme conditions,

combined with design advantages in steel struc-

tures:

• Extremely high anti-skid effect, high displace-

ment space and maximum drainage through

75 mm wide openings

• Extra-high load-bearing capacity, cost benefits

in steel construction

• Width up to 800 mm–ideal for large surfaces

and platforms

The lateral system perforation simplifies

installation.

The load-bearing upward profiling: 20 mm

which as ”profile” allows such high widths and

lump loading in one piece.

Convex ”olives” (punched upwards) ensure a

high non-slip effect and create maximum dis-

placement space. Concave ”olives” (punched

downwards) ensure maximum drainage and dis-

placement space.

Graepel-Stabi l SDescription

Technical data

Load values

The safety grating Graepel-Stabil S obtains its high load-bearing

capacity from the strong surface profiling which has a height of

20 mm. Depending on grating width (B), sheet thickness (D), load

surface (a1 x a2) and material, a factor of 10 and higher may result.

Example:

• Grating width 600 mm

• Sheet thickness 2.5 mm

• Load area 200 x 200 mm

Graepel-Stabil The safety grating which has become a classic,

for universal use on floor surfaces, walkways

and stairs:

• High anti-skid effect on olives 45 mm wide,

high displacement space and enormous

drainage effect for objects below stop limit of

15 mm

• High load-bearing capacity with substantial

benefits in steel construction

• Elements up to 12 metres in length


installation.

The load-bearing upward profiling: 10 mm

which as ”profile” allows such high widths and

lump load-bearing capacity in one piece.

Convex ”olives” (punched upwards) ensure a

high non-slip effect and maximum displacement

space. Concave ”olives” (punched downwards)

ensure maximum drainage and displacement

space.

Program-controlled

perforation groupsAppropriate control of the production plant allows

groups of perforations and stampings to be pos-

itioned separately. This means that not only rect-

angular groups of perforations can be punched.

Graepel-Round SThe Graepel-Round S is a universal grating for use

on floor surfaces and stairways. It offers adequate

displacement space and a safe footing. Its effect-

iveness lies in the combination of

• Large free cross-section (good drainage effect

and weight saving)

• High load-bearing capacity (benefits in steel

construction and architecture)


installation.

Load-bearing upward profiling: 3 mm profile

has a higher lump-load bearing capacity than

gratings with less profile or closed surfaces.

The upwardly punched holes ensure a good

anti-skid effect, displacement and drainage. The

holes punched downwards increase displacement

and drainage.

Program-controlled

perforation groupsAppropriate control of the production plant allows

groups of perforations and stampings to be pos-

itioned separately. This means that not only rect-

angular groups of perforations can be punched.

Graepel-Round KAn ”open safety grating” which is particularly

suitable for pedestrian areas but also for industrial

uses such as canteen kitchens, slaughterhouses,

etc.

• Anti-skid with adequate displacement space

and good drainage effect; easily cleaned

• Satisfactory screening effect, e.g. on stairways

and pedestrian bridges


installation


has a higher point-loading capacity than, for

example, gratings with a lower profile or plain

surfaces.

The upwardly punched holes ensure a good anti-

slip effect, displacement and drainage. The holes

punched downwards increase displacement and

drainage.

Graepel-Diamond

and Graepel-ConeThese two gratings with closed surfaces are used

in industrial and public areas

• Where technical utility has to meet certain

architectural requirements (high tech)

• Where a measure of compromise is necessary,

i.e. a certain anti-skid effect and displacement

space are required, where the view between

two levels should be screened, where nothing

should drop through, and where finer

(non-industrial) shoes are worn

Fas tening technology

Walk safe, s tand safe

The entire know-how

for safety underfoot.

Innovative and effective. A programme

full of ideas for safety underfoot

Uncompromising and competent wherever the

danger of slipping or skidding has to be reduced,

we are your contact partner. As specialists with a

worldwide reputation in ”underfoot safety” we

make products which contribute to safety at work

and accident prevention in day-to-day industrial

practice. Uncompromising and competent wher-

ever anti-skid surfaces are required.

More safety–fewer accidents

The idea behind our wide range of sheet-metal

gratings can be summed up in a few simple

words: ”more safety–fewer accidents”. Their

classification extends from ”extreme anti-skid”

to ”lounge quality”. Regardless of which of our

products you choose, you are guaranteed the

highest standard of quality and an unequalled

degree of safety.

Economical and individual

A high standard of underfoot safety does not have

to be expensive. We produce profiled sheet-metal

gratings by the metre, for example, scaffolding

planks, steps and flooring. Or pre-assembled parts

such as stepboards and access ladders for trucks

and machinery, to mention just two other appli-

cations. Regardless of the problem you have to

solve, our practical and original range of products

ensures that you can stand and walk in perfect

safety while working for the success of your com-

pany.
