Product Details

Antop Global is a high-tech enterprise that combines technological development , production, sales and services of the GFRP rebar and GFRP rock bolt. We are already in this field for over 10 years with registered capital of 17.5 million RMB. Now we worked together with China University of Mining and Technology, and build academician workstation inside factory. We have strong R&D, QC and Test Department, which consist of high-qualitymanagers and engineers with strong innovative ability.


Advantages:

(1) Light weight (1/4 of the steel mesh)

(2)High breaking load

(3)Anti-corrosion and durability

(4)Fire retardant

(5)Anti-static: It has no electrical conductivity, and no sparks will be produced when being cut. It is particularly suitable for high gas zones;

(6)Cuttability: It avoids damages to cutter heads, and does not delay excavation;

(7)Non-combustible (high thermal insulation)

(8)Non-magnetic


We overcome the traditional difficulty of low torsion and have researched the high torsion of GFRP rockbolt . It can improve the supporting by prestressing.
