SPA-H Weathering Alloy Steel Plate for Container

SPA-H is a high-strength low-alloy weathering steel produced in accordance with multiple international standards, including AISI, ASTM, BS, DIN, and JIS.

Manufactured mainly by hot rolling, SPA-H corten steel plate and coil are specifically designed for structural applications exposed to harsh atmospheric environments.

By adding small amounts of alloying elements such as copper (Cu), chromium (Cr), nickel (Ni), and phosphorus (P) to ordinary carbon steel, SPA-H weathering steel forms a dense and stable oxide (patina) layer on its surface during atmospheric exposure. This protective layer significantly improves corrosion resistance, extending service life while reducing the need for painting or surface coatings.

Compared with conventional carbon steel, SPA-H weathering steel offers 2–8 times higher atmospheric corrosion resistance, and its coating durability is 1.5–10 times longer.

In addition to excellent weather resistance, SPA-H steel provides outstanding strength, toughness, plasticity, weldability, wear resistance, fatigue resistance, and high-temperature performance, making it suitable for demanding structural applications.
