Steel grating is an integral construction one-piece fiberglass roving reinforced unsaturated polyester resin (FRP) grating. This grating is typically composed of 60-65% by weight resin and immensely strong continuous glass fiber by a specially designed process that provides a property of good corrosion resistance, angular silica particles are em- bedded in the top surface of grating to provide long lasting slip resistant surface.

Steel /Bar Grating Fabrications: The serrated steel/bar grating is made of serrated bearing bar and cross rods. They placed horizontally and vertically, and at an equal pitch apart, by welding with 200ton hydraulic resistance automatic welding equipment then cutting punching and handing ends. Center to Center Bearing Bar Spacing: we usually supply with 30mm or 40mm Center to Center Cross Bar Spacing: usually supply with 50mm or 100mm. and we are also pleased to accept your special order.
