JIS SPA-C Cortren Steel Sheets Chemical Composition
SPA-C steel plate under JIS G3125 standard is a hot-rolled structural high-quality steel with improved atmospheric corrosion resistance. Therefore, JIS SPA-C steel plate is also called weathering steel or atmospheric corrosion resistant steel. This steel plate can be used for vehicles, buildings, towers and other structural parts.
