When SPA-H's weathering steel is exposed to the air, after contact oxidation with air and moisture, a dense oxide film will be formed on the surface, and the copper, nickel and other elements in it adhere to the surface, forming a barrier against continued erosion from the outside world. The interior can be kept in good condition for many years without being destroyed. Ordinary steel plates are exposed to the outside world, and over time, oxidation will continue to erode to the inside. Therefore, the service life of weathering steel is much higher than that of ordinary steel plate, and it is an economical and applicable steel grade from the perspective of long-term cost, which is worth promoting.
