Duplex Coating Rock Bolt
There are two corrosion-prevention measurements on the bolt surface: epoxy coating and hot-dip galvanizing. Epoxy coating is made from a 100% epoxy resin coating material. Hot-dip galvanizing is a method that anchor bar gains metallic coating by immersing into molten galvanizing zinc.Download PDF
