Composite covers development process: (1) its strength after Shisu covers. The vehicle can carry more than 40 tons. (2) its overall performance between Shisu covers and concrete covers, better than concrete; covers technology can be applied to situations requiring high. (3) It is the most prominent advantage of not using steel skeleton reinforced, and to the fiberglass composite reinforced composite covers Qianjiang equipment belonging GRC products. Therefore composite covers, which in the case of continuous steel prices, more affected advantage. Because it does not contain iron, which is more security than Shisu and fiber reinforced concrete covers. By using high-performance resin, fiberglass and a special production process recipe Yellowstone composite covers production, to ensure the penetration of fiberglass resin composite covers Xiaogan model, greatly enhances the adhesion of both, so that the material under cyclic loading , no internal damage, thus ensuring the life of the product, and the same with the superiority of other resin composite covers. Eliminate the shortcomings of poor adhesion. Resin composite material covers the use of unsaturated resin, fiberglass and other materials and steel skeleton with a special production process compounded by high-temperature grinding pressure molding, material no recycling value, very difficult to remove the rebar (steel removal costs exceed the value of steel) So with active anti-theft feature.
