Self-drilling Hollow Rockbolt with High Strength for Soft Soil

Product Detail

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.

Main Features:

1. Safe,reliable,and time saving

2. Easy installation
