Surface Preparation
The steel surface to be coated must be thoroughly cleaned of oil, scale, rust, old coatings, etc. This can be achieved through shot blasting or sandblasting methods to meet the Swedish rust removal standard Sa2.5 level, with a roughness of 30~70μm. Alternatively, manual rust removal methods can be used to achieve the Swedish rust removal standard St3 level, with a roughness of 30~70μm.
