Gratings
1. MOLDED GRATING :
“ARHAM” Molded Grating is an integral construction one-piece Fiber Glass roving reinforced
unsaturated polyester resin (FRP) grating.
This grating comprises of 60-65% resin by weight and immensely strong continuous glass.

Advantages of “ARHAM” GRATING
Corrosion Resistance
Eliminates normal corrosion problems
High Strength
Pultruded fiberglass has a high glass content and will give strength to weight
ratios that
surpass equivalent metal products
Low Maintenance
Fiberglass does not require a periodic maintenance program thereby reducing
your repair
costs. Will not rust streak onto adjacent structures
High Impact Resistance
Will return to its original position without any permanent deflection or
distortion...even when
subjected to heavy objects being dropped on the grating.

4.
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 coated
with 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 Effective

5.
Safety & Comfort
The immediate and accumulated negative effects of working on a grating surface are lessened
Flooring
considerably with ARHAMª Grating. This is due primarily to the larger surface area contacted
while Stairs or kneeling on the surface.

6. 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.
Corrosion Resistant
Fiber by a specially designed process, provides a property of good corrosion resistance. Angular

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
resistant than Pultruded Grating using the same resin system.
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

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.
