Galvanized bolts are bolts that have undergone a galvanization process, which involves coating the bolts with a layer of zinc to provide protection against corrosion. The galvanization process creates a protective barrier that helps prevent the bolt from rusting when exposed to moisture and other corrosive elements.

Rock bolts are commonly used in civil engineering and mining to reinforce and stabilize
rock masses. A rod or bar is inserted into a drilled hole, which is then grouted in place using
cement or resin. FRP Rock bolts withstand tensile forces and evenly distribute load,
eventually increasing overall strength. They control rock movements, reduce deformation
and prevent collapses.
