Durable Weatherable and Weatherproof Roofing FRP Sheets

FRP grating is also called Fiberglass reinforced Polymer grating. There are FRP molded grating and FRP pultruded grating according to its molding patterns. It's originated from USA in the Seventies. In early Nineties, FRP gratings got rapid development in China after introducing the technology from overseas.
     
     By braiding the fibers and heating the whole casting, molded grating is a kind of molding product which use fiberglass as reinforced material and the thermosetting resin as the matrix. By pultrusion molding equipment, pultruded grating is a kind of assembling product which use fiberglass filament, fiberglass mat,  polyester surface mat as the reinforced material and the thermosetting resin as the adhesive. The voidage of Molded grating is relatively large and it's hard to be scattered because of its small mechanical loss after cutting; Pultruded grating has the character of its strong loading capacity in length, small loss after cutting the material and the high aging resistance.
     
      FRP gratings could replace the steel, carbon steel and iron casting products in common construction field. It has a competitive advantages considered from the unite price, transport cost, the installation and the maintenance. FRP grating has a more and more extensive application prospect as a new-model and light construction material.
