JIS G3302 Coil Applications
- SGHC grade is ideal for light-duty applications such as roofing sheets, ductwork, and household appliances.
- SGH340–SGH400 are suitable for moderately stressed parts including HVAC systems, panels, and frames.
- SGH440–SGH540, with higher tensile strength, are used in automotive structural parts, industrial enclosures, and reinforced components.
These steel sheets offer a cost-effective solution for manufacturers needing both protection and performance in outdoor or humid environments.
