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.
Unique corrosion protection
The rock bolt surface can be hot dip galvanized with zinc thickness
≥80um.
Epoxy coated threaded bars , thickness ≥80um or higher 220um, 280um.
Full accessories are available: .
Bearing plates with angle compensation, different finishes,
architectural features.
Borehole spacers : lantern or skid
Tubes for borehole grouting (bottom up)
Coupler forks for suspending sections within the borehole
Application
geotechnical, soil nailling,rock bolts,ground anchors,form
work,reinforcement,post-tension system,bridge ,micro piles,mining
and tunneling ect.
