Firewalk Safe-T-Span Pultruded Grating is a light weight, corrosion resistant FRP composite grating manufactured with phenolic resin and engineered to meet the full requirements of ASTM F3059. It is commonly used for flooring, platforms and walkways where resistance to high temperatures and low smoke emissions is required. Firewalk grating is also designed for use in areas where conventional metallic grating would be subject to corrosion or impose a weight penalty
Firewalk Safe-T-Span Pultruded Grating is currently approved to ASTM F3059 at a thickness of 1.5-in. and bar spacing range of 1-in. to 1.5-in. on center.
