First the parts are chemically cleaned to remove any oil or dirt. Once rinsed the parts are lowered into a bath of molten zinc where is heated to around 450°C. The parts are then left to cool in a quench tank, once fully cooled the zinc is then metallurgically bonded to the steel.
In hollow sections holes are drilled at certain points, this prevents the build up of gasses. It also allows the molten zinc to flow inside completely encasing the item thus giving it superior protection. Once finished these holes can be plugged to prevent water ingress and to hide them.
