1.Product description

    FRP anchor bolt  is a new type of products to replace the iron bolt, having the features of no rust, non-corroding, antiflaming, antistatic, light weight, easy to use, etc. And it’s non pollution and harmless to human body.

Full thread, resin glass, fiber reinforced plastics, is a composite material of high performance resin and high strength glass fiber, along with a variety of additives, processing  with a special processing technology.

2. Component

     FRP Plate, FRP nut, FRP anchor body5. Application

    Because of the special material, it’s suitable for most roadway construction. And it will gradually replace the traditional steel anchor. It’s also called glass fiber anchor, or glass fiber reinforced plastic anchor. 

4. Specification

Rod body easy to cut:  since FRP is composite material, it is easy to cut, and protectable to the coal winning machinery.Anti-explosion, anti-static:  cutting won't  park, be very favorable for safe construction of roadways, very suitable for gas concentration areaGreat anticorrosion:  high bearing capacity, strong strentching resistance, the strength of rod body is better than that of screw steel with equal diameter.Easy operation:  the weight is only a quarter of the same specification steel anchor. Conveniently used in the tunnel and coal like narrow space. Easier construction, lower labor intensity.The price of FRP anchor is superior to the traditional steel anchor, if promoted and more widely used, it will surely reduce the dependence of the steel, and also conform to the state advocates of the aim of building economical society.
