玻璃钢格栅板比较轻；钢格板较重。玻璃钢格板是经树脂和玻璃纤维复合而成，其密度较小，与钢格板对比，玻璃钢格栅的密度仅为钢的1/4，铝的2/3，而强度为硬质聚氯乙烯的10倍，肯定强度超越铝材，到达通常钢的水平。其自重轻，能够大大的削减基础支持，削减了工程的资料本钱。
Fiberglass reinforced plastics (FRP) grids are lighter and steel grids are heavier. Fiberglass reinforced plastics (FRP) grids are made of resin and fiberglass. Compared with steel grids, the density of FRP grids is only 1/4 www.zhijia.org.cnwww.zhidiaojia.org.cnwww.qibijizhamen.com.cnwww.juanyangqibij.cn www.qingwuji.net.cnwww.yasiban.cnof steel and 2/3 of aluminium. The strength of FRP grids is 10 times that of rigid polyvinyl chloride. It is certain that the strength of FRP grids exceeds that of aluminium and reaches the level of normal steel. Its self-weight is light, which can greatly reduce the basic support and reduce the cost of Engineering information.
