SPA-H steel plate important information

SPA-H steel plate has strong corrosion resistance under weather conditions such as rain, snow, ice and fog. A dark brown oxide layer can be formed on the surface of the SPA-H steel plate to inhibit the deep penetration of arsenic. Therefore, the use of SPA-H steel plate saves spraying costs and expensive rust maintenance costs.
