The SPA-C Corten Steel Plate is a high-strength weathering steel designed to withstand harsh atmospheric conditions.
Known for its excellent corrosion resistance, this steel develops a protective rust layer when exposed to natural weather, eliminating the need for painting or other rust-preventive coatings.
Its durability, low maintenance requirements, and unique aesthetic make it ideal for construction, industrial, and decorative applications.
Standard
JIS G3125: Japanese material standard for hot-rolled steel with superior atmospheric corrosion resistance.
Category: Corten steel / weathering steel.
