FRP Pultruded Grating

FRP Pultruded Grating is a series of I or T shaped structural members (the bearing bars) that are mechanically strung together with evenly placed dowels or cross bars. This is similar to the way many steel and aluminum gratings are assembled.

FRP Pultruded Grating are assembled from pultruded shapes. These shapes (I-Bars, T-Bars, etc.) are manufactured by pulling fiberglass rovings and mats through guides, then into a resin bath, then wrapped with a surfacing veil, then finally pulled through a heated die to form the desired bar shape.

Types:T-Type or I-type

Height: 25mm,30mm,38mm,50mm etc.

PH	Phenolic resin	Good	Low smoke,low toxicity,and high flame retardant requirements

Features

Unlike molded grating which has equal strength in both directions, FRP Pultruded grating is stronger in the longitudinal direction as it is fabricated from bearing bars & interlocking rod and groove bar assemblies. For that reason FRP Pultruded grating sizes are specified by width (the cross-rod dimension) x length or span (the bearing bar dimension).

Corrosion Resistance
Fire Resistance
Light Weight & High Strength
Safety & Anti-slip
Electrical Insulating
Aging Resistance
