JIS SS490 structural steel angle is a high-strength carbon steel section, significantly stronger than SS400, allowing for reduced weight and thickness in designs. It is hot-rolled and available in equal and unequal leg types. Surface treatments include black, galvanized, or painted finishes. Note: Due to low corrosion resistance, black angles are not recommended for wet or corrosive environments; galvanized or painted options are preferred.
