Carbon steels
• Classified as low, medium and high:
1. Low-carbon steel or mild steel, < 0.3%C, bolts, nuts and sheet plates.
2. Medium-carbon steel, 0.3% ~ 0.6%C, machinery, automotive and agricultural equipment.
3. High-carbon steel, > 0.60% C, springs, cutlery, cable.

HOW TO MAKE STEEL?
Benefits of Structural Steel
Some benefits associated with use of structural steel for owners are:
• Steel allows for reduced frame construction time and the ability to construct
in all seasons
• Steel makes large spans and bay sizes possible, providing more flexibility for
owners
• Steel is easier to modify and reinforce if architectural changes are made to a
facility over its life
• Steel is lightweight and can reduce foundation costs
• Steel is durable, long-lasting and recyclable (AISC 1999)
