Structural Steel
Structural steels are weldable carbon-manganese steels specified by strength class, such as IS 2062 E250 and E350 or EN S355JR. They are supplied as plate, sheet, coil and sections for fabrication.
When to Choose Structural Steel
- The part is welded or fabricated
- Strength is specified by yield class
- The material is plate, sheet, coil or a section
- Building, machinery frames or general fabrication are the end use
