Gratings

1. MOLDED GRATING :

“ARHAM” Molded Grating is an integral construction one-piece Fiber Glass roving reinforcedunsaturated polyester resin (FRP) grating.

This grating comprises of 60-65% resin by weight and immensely strong continuous glass.

2. PULTRUDED GRATING :“ARHAM” Pultruded Grating is assembled pultruded H-sections or T-sections linked by rodper distance into panel. The distance is decided by an open area rate. Pultruded gratingprovides extremely high unidirectional strength and stiffness, since H-section or T-sectioncan provide great mechanical load whereas the rods work as Connector.Pultruded Grating are stronger than Molded Grating because of the higher glass content.

Advantages of “ARHAM” GRATINGCorrosion ResistanceEliminates normal corrosion problems

High StrengthPultruded fiberglass has a high glass content and will give strength to weight ratios thatsurpass equivalent metal productsLow MaintenanceFiberglass does not require a periodic maintenance program thereby reducing your repaircosts. Will not rust streak onto adjacent structuresHigh Impact ResistanceWill return to its original position without any permanent deflection or distortion...even whensubjected to heavy objects being dropped on the grating.Non-Conducting/Non-Sparking

Fiberglass products are non-conducting which eliminates the potential of a shock hazard inelectrical applications.Lightweight

Extremely lightweight compared to its metal counterparts. This makes for easy handling andinstallation.Fire Retardant (Optional)As with all ARHAM Fiberglass products, they are fire retardant in accordance with ASTM-E-84Class I.

UV Inhibited

Contains an ultraviolet inhibiting additive in the resin in addition to a synthetic surfacing veil

used in the pultrusion process to give an extra layer of this resin on the surface.

Easily Fabricated in the Field Can be easily cut and drilled using normal metal or woodworking tools in conjunction with an

abrasive blade or bit. As with all fiberglass products, any cut or drilled areas should be coatedwith a resin afterwards to prevent premature degradation of the composite.

Low Thermal Conductivity Fiberglass has a very low level of thermal conductivity and will not transfer heat or cold like

metal product.

Cost EffectiveOur fiberglass systems will give long life in extremely harsh chemical environments, reducing

the need to replace in a short period of time due to severe corrosion.

SurfaceNon-skid surface of recycled crushed glass, applied to an adhesive, then painted; to offer

increased surface traction. Won’t fatigue with use, and alleviates slippage in wet, oleaginousareas. Withstands most chemically aggressive environments.

Non-InterferingFiberglass is transparent to radio waves. This is important to any facility or structure which

depends on two-way radio, cellular phone or electronic pagers for communications.

Safety & ComfortThe immediate and accumulated negative effects of working on a grating surface are lessenedconsiderably with ARHAMª Grating. This is due primarily to the larger surface area contactedwhile walking or kneeling on the surface.

Model Gratings“ARHAM” Molded Grating is an integral construction one-piece Fiber Glass roving reinforcedunsaturated polyester resin (FRP) grating.

This grating comprises of 60-65% resin by weight and immensely strong continuous glass.Fiber by a specially designed process, provides a property of good corrosion resistance. Angularsilica particles are em- bedded in the top surface of grating to provide longlasting slip resistantsurface (optional)The surface of FRP Molded Grating can be concave top, flat top, grit top,Decorative PatternCover,Grit Cover and Smooth Cover

Pultruded Gratings

“ARHAM” Pultruded Grating is assembled pultruded H-sections or T-sections linked by rod

per distance into panel. The distance is decided by an open area rate. Pultruded grating

provides extremely high unidirectional strength and stiffness, since H-section or T-section

can provide great mechanical load whereas the rods work as Connector. Pultruded

Grating are stronger than Molded Grating because of the higher glass content.

FRP Pultruded Grating can span long distance for any given load. Of course, Pultruded

Grating can be gritted or covered panel. However molded grating is more corrosionresistant than Pultruded Grating using the same resin system.

RANGE :

The loads are determined by a deflection of L/125. A deflection of L/125 is

equivalent to 0,75% refering to the span.

The point load has been generated with a load stamp of WxL = 200x200mm.We recommend to assay the applicability cases.Deflection less than 0.5mm and greater than 19mm has been omitted
