full thread FRP anchor rod length are equidistant cloth with thread, namely "full thread";

corrosion resistance anchor the substrate used are durable materials, and through the composite molding process. Life of up to 100 years. Can be used as a permanent support materials;

High tensile strength steel is about the same size twice the load;

Lightweight weighs the same specification steel weight of 1/4, greatly reduce the labor intensity, but also reduces the cost of transportation;

Antistatic non-conductive, cutting will not produce sparks, especially for high gas region;

non-combustible, flame retardant, high heat insulation;

cutability avoid damage to the cutting head, without delay tunneling;
