JIS G3114 SMA400BP steel plate is a high-strength weathering steel grade under the Japanese Industrial Standards (JIS), specifically designed for enhanced resistance to atmospheric corrosion. SMA400BP weathering steel is widely recognized for its ability to form a protective rust layer when exposed to weather conditions, making it an ideal choice for outdoor structures. SMA400BP Weathering Resistant steel offers a unique combination of durability and aesthetic appeal, often used in applications where maintenance costs need to be minimized.
SMA400BP Weathering Steel belongs to the JIS G3114 standard, which specifies hot-rolled atmospheric corrosion-resistant steels for welded structures. This grade is engineered to withstand harsh environmental conditions, such as rain, humidity, and industrial pollution, without the need for frequent painting or coating.
Thickness: 6 mm to 100 mm
Width: 1000 mm to 3000 mm
Length: 3000 mm to 12000 mm (custom lengths available upon request)
The chemical composition of SMA400BP steel is carefully balanced to ensure optimal corrosion resistance and mechanical strength.
| Element | C (%) | Si (%) | Mn (%) | P (%) | S (%) | Cu (%) | Cr (%) | Ni (%) |
