Introduction of SPA-H weathering steel

SPA-H weathering steel belongs to the Japanese grade weathering steel, which is a kind of atmoSPHEric corrosion resistant steel. It is a cost-effective weathering steel and is widely used in the container manufacturing industry. The amount of steel used in the container is relatively large, and the thickness between the commonly used specifications is 1.5MM-2.0MM. The common thickness on the market is between 1.5-16MM. Now SPA-H weathering steel is more and more used in landscape decoration and garden landscape industry, which reflects its wider use.

SPA-H weathering steel is made by adding a small amount of corrosion-resistant elements such as copper and nickel.

When the weathering steel of SPA-H is exposed to the air, it will form a dense oxide film on the surface after contact with air and moisture to oxidize, in which copper, nickel and other elements are attached to the surface, forming a protective barrier against continued external erosion. barrier. The interior can remain in good condition for many years without being damaged. While ordinary steel plates are exposed to the outside world over time, oxidation will continue to erode inside. Therefore, the service life of weathering steel is much higher than that of ordinary steel plates. From the perspective of long-term cost, it is an economical and applicable steel grade and is worthy of promotion.
