Hot dip galvanizing

steelindustrialmedium series

With hot-dip galvanizing, the material to be galvanized is immersed in molten zinc. As a consequence of the mutual diffusion, a layer of differently composed zinc-iron alloy layers forms between the zinc and the steel surface, whereby a coating of pure zinc usually remains on the outermost layer. Hot-dip-galvanized parts are especially resistant against atmospheric, chemical, thermal and mechanical loads. Through the immersion in the liquid melt, cavities can also be reliably protected. In the area of hot-dip galvanizing, we offer a unique, self-developed coating process using the rack process. The parts – such as screws for the wind power industry – that leave our system are “ready-to-build.” They can be installed directly with no thread rolling – which can damage the coating.
