Series of pultrusion profiles include square tubes, rectangular tubes, round tubes, angles, I-shapes, channel, rod, and others custom profiles. After proper combination and connection, they can widely used in many fields such as: FRP grating platform, walkways, ladder, guardrail, plank of cooling tower, sporting profiles, tool handles and other load structures. It has properties such as: light weight, high strength, corrosion resistance, low maintenance and beautiful appearance. Mold resin system for FRP grating products: 1) Type O (orthophthalic polyester resin): a) These gratings can be used in seawater, weak acid, and other special environments b) Operation temperature: *0 ~ *0oC 2) Type I (isophthalic polyester resin): a) These gratings can be used in middle concentration inorganic acids, inorganic alkalis, and other special environments b) Operation temperature: *0 ~ *0oC 3) Type V (vinyl ester resin): a) These gratings can be used in corrosive environments, both acid and alkali b) Operation temperature: *0 ~ **0oC 4) Type P (phenolic aldehyde): a) Has exceedingly good fire resistance, acid resistance and dissolvent resistance b) Oxygen index: *0 c) Low smoke levels, high temperature resistance 5) Long-term usage temperature: **0oC
