Most often, metal stairs are used in various industries. This means that they must withstand a sufficiently large load and be particularly reliable. Hot-dip galvanizing of stairs helps to protect the steps from corrosion for a long time. The main advantage of this method of corrosion protection is that zinc reacts with steel. The result is a reliable protective layer. It is not damaged on impact, long service and can withstand heavy mechanical loads.
Galvanizing of ladders occurs in special shops. Initially, the parts are machined to get rid of coarse dirt. In the future, with the help of acids, the metal is purified from fat and scale. Then the parts are covered with a layer of flux. Fluxing provides a particularly strong bond of zinc and steel, as well as prevents the occurrence of rusting processes that occur as a result of contact with oxygen steel.
The prepared part is lowered into a bath with zinc. Important speed with which the item is lowered into the zinc bath and removed from it. The rate of immersion affects the reliability of the connection, and the rate of extraction allows you to adjust the thickness of the zinc layer.
Hot dip galvanizing stairs – a reliable way to protect them from rusting for a long time. Even if the zinc layer is broken, an invisible layer of cathodic protection will prevent corrosion of the metal.
