Key point is higher glassfiber content(65%-70%)on bearing bar direction, the advantage especially under large span.
FRP PROFILE
Pultruded FRP grating has a majority characteristics of the molded FRP grating,but also has its outstanding advantage,key point is higher glassfiber content(65%-70%)on bearing bar direction, the advantage especially under large span. It will reduce foundation support, cut down the engineering expenses.
1 Chemical resistance
Choose the ORTHO, ISO or vinyl resin as raw material,if use surface mat the corrosion resistance will be better.
2 Light weight
The weight of pultruded FRP grating is very light, only 1/4 of steel material, easy transport, reduce transportation expenses.
3 High strength
According to weight ratio the resin occupy 35%, glassfiber 65%, the strength/weight ratio very high.
4 UV resistance
We can increase ultraviolet agent and polyester surface mat in the formula to obtain the best UV resistance effect.
5 Fire retardancy
Oxygen index 25 or 26 1 grade retardancy effect. (According to the engineering requirement)
6 Other characters
Impact resistance, maintenance free, process easily, antiskid safety, heat and electricity insulation etc…
