How to calculate the price of A588 Grade A steel plate

The principle of weather resistance of A588 Grade A steel plate: After adding phosphorus, copper, chromium, nickel and other weathering elements to the steel, the A588 Grade A steel plate forms a dense and highly adherent oxide layer between the rust layer and the substrate. The dense oxide layer has the characteristics of stable and uniform natural rust red color, which can hinder the penetration of oxygen and water in the atmosphere into the substrate, protect the substrate under the rust layer, and slow down its corrosion rate.

A588 Grade A steel plate weathering steel price = steel plate raw material price + corrosion treatment price.
The price of rust treatment is 90~200 yuan/㎡ according to different processes. The weather-resistant steel takes 3mmA588 Grade A steel plate as an example, and the raw material is about 110 yuan/㎡.

Therefore, the price of A588 Grade A steel plate is 200~400 yuan/㎡. Of course, changes in the thickness of the A588 Grade A steel plate and the quality of the plate will correspondingly affect the price of weathering steel for the A588 Grade A steel plate. (This price is the price of ordinary mid-range products, for reference only).
