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. 2. PULTRUDED GRATING :

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

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. walking Trench Covers ARHAM HI-TECH DESIGN AND SOLUTION PVT.LTD. 2, Gamdevi Ambika Temple, Bridges Kirol Road, Vidyavihar (W), Mumbai-400086.

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
