Epoxy Coated FULL THREAD BAR 32MM PSB930
epoxy coated Threadbar Anchor System
1 Specification:
Threadbars, which ensure ease of coupling and stressing. The wide range of capacities (up to 4500 kN) enable threadbar anchors to be used for many applications.
Typical section lengths range from 6 to 12 meters. Where multiple short sections are required, the Anchor System may be more suitable.

1)Quickly installed, easily grouted
Rock bolt is in many ways a typical combination mechanical bolt, installed as a temporary rock support and later grouted to become permanent. But there are important differences. It’s quick and easy to install, simple to grout even with varying consistency and the polypropylene sleeve seals the bolt against corrosion.
The rock bolt surface can be hot dip galvanized with zinc thickness ≥80um.
