Product Specifications

JIS G 3114 Corten Steel Coil is a Japanese industrial standard for hot-rolled atmospheric corrosion-resistant steels used in welded structures. This steel is developed for structures exposed to outdoor environments where rust protection is essential but coatings are not preferred.

JIS G 3114 Corten Steel Coil

The steel coils naturally develop a stable oxide layer (patina) that slows further corrosion and enhances durability, making it ideal for bridges, guardrails, containers, and other infrastructure applications throughout Asia and beyond.


🔹 Available Grades

Standard Available Grades
JIS G 3114 SMA400AW, SMA400BW, SMA400CW, SMA400AP, SMA400BP, SMA400CP, SMA490AW, SMA490BW, SMA490CW, SMA490AP, SMA490BP, SMA490CP, SMA570W, SMA570P

Each grade differs slightly in strength, impact resistance, and chemical composition to meet the specific demands of various welded applications.
