Steel pre-treatment refers to that before processing, the surface of the steel products is blast to remove the rust and coated with undercoat.

The pre-treatment can improve the anti-erosion of mechanical products, metal structual parts and improve the anti-fatigue of steel plates to prolong its life. The surface of steel plates will be optimized for processing and numerical controlled incision and precise s blanking. Beside, before treatment, the shape of steel products is formulated, which is in favor of rust removing and automatic coating, so pre-treatment for steel products can improve the efficiency of cleaning and minimize labor and pollution.
