1. Hot-dip galvanizing anchor bolt
2. Duplex Coating Rock Bolt
3. Stainless Steel Anchor Bolt

1. Hot-dip galvanizing anchor bolt

(1) Introduction:

Hot-dip galvanizing is a kind of corrosion-prevension measurements on the bolt surface. The Oxidation film easily occurred on the zinc coating in the moist air. It can be isolated with water and air to prevent the chemical etching and the rusting. So the preservative effect is very well as a permanent support. It is applied to conditions which are inflenced by underground water such as road, railway, water conservancy project, etc.

2. Duplex Coating Rock Bolt

(1) Introduction:

The duplex coating rock bolt adopts two corrosion-prevention measurements on the bolt surface, hot-dip galvanizing and epoxy coating which can prevent corrosion very well. It is mainly used in conditions which are inflenced by underground water such as road, railway, water conservancy project, subsea tunnel, etc.

3. Stainless Steel Anchor Bolt

(1) Introduction:

Stainless steel anchor bolt is made of stainless steel materials. Owning to its good welding performance & inoxidizability, stainless steel rock bolt are mainly used in the permannent support of large initial stress of surrounding rock, or other projects which have special requirement for corrosion resistance, such as subsea tunnel, seaport, seawall and some projects in the industrial pollution area. The service life of stainless steel anchors can reach 120 years.
