Product Features

FRP rockbolt is a new support material composed of FRP full thread bolt, FRP nut and FRR plate. It features light weight, high strength, corrosion resistance, and easy cutting. It is widely used in coal mines, tunnels, slopes, and foundation pit support. Self-drilling hollow rockbolts are primarily utilized for soft soil where pre-puring is difficult.
