FRP pultruded pultrusion "I", "T"-shaped profile as the bearing bars wear solid pipe or bar as the connection rod plate made with a gap of some assembly process. Characteristics of pultruded 
 Pultruded FRP grating has a molded fiberglass grating characteristics but also their significant differences, the most important point is on the direction of the bearing bar high glass fiber content (65% -70%), and is therefore molded FRP gratings compared to more the superiority of large span, this will reduce the base support, and reduce the cost of the project. 
 Chemical resistance 
 Stupid selection of good neighbors, between stupid, and vinyl resin and pultruded fiberglass grating, with the performance felt with excellent corrosion resistance. 
 Light 
 Pultruded FRP grating is only about a quarter of the steel weight, very easy to handle, thereby reducing handling costs. 
 High strength 
 Pultruded based on the weight ratio of about resin accounted for 35% accounted for 65% glass fiber, providing a very high strength / weight ratio. 
 UV resistance 
 Pultruded in the formula are added to the anti-UV agents containing polyester performance felt to get the best UV protection. 
 Flame-retardant 
 Flame-retardant effect of a 25 or oxygen index of 26 or more (according to project needs) 
 Other excellent performance 
 Impact-resistant, maintenance-free, easy processing, non-slip safety, insulation adiabatic.
