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.
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.
