SPA-C Corten Steel Plate

SPA-C is another weathering steel grade under JIS G3125, designed for moderate-strength structural applications that demand excellent resistance to atmospheric corrosion. Compared to SPA-H, SPA-C has a slightly lower yield strength and is more commonly used in lightweight structures and decorative outdoor applications.

Its natural rust layer protects against further corrosion, making it ideal for applications that prioritize appearance and durability without the need for coatings.
