Duplex Coating Rock Bolt-Self Drilling Rock Anchors By Sinorock

Duplex Coating Rock Bolt

Duplex Coating Rock Bolt

Brief Introduction:

There are two corrosion-prevention measurements on the bolt surface: epoxy coating and hot-dip galvanizing.
Epoxy coating: an epoxy resin coating material, which is acid-resisting and solidified at room temperature.
Hot-dip galvanizing: a method that anchor bar gains metallic coating by immersing into molten galvanizing zinc.

Feature:

1. Excellent property for resisting concentrated acid.
2. Excellent adhesive action for the surface of cement.
3. Excellent property for moisture-proof, waterproof and thermal aging.
