Surface Treatment of Steel

Surface treatment of steel includes chemical treatment and physical treatment.

The former is mainly acid pickling. After the corrosion treatment is carried out by chemical reaction on the steel surface, the effect can be achieved by cleaning the steel wire brush roller made of 304 # stainless steel wire (acid and alkali resistant solution).


Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of beauty and rust prevention. The main method is hot galvanizing.

Hot dip galvanizing is a chemical treatment and an electrochemical reaction. The hot-dip galvanized coating is thick, and the national standard zinc layer is about 85nm, which can effectively isolate water and air, protect the substrate from corrosion and rust, and have strong corrosion resistance.


The physical treatment is carried out by mechanical processing, such as shot blasting, sand blasting, high-pressure water, etc. to achieve the effect. SCS technology belongs to the latter.
