Angle steel can be classified based on shape, size, and use:
- Equal angle steel: Both sides are of equal length, widely used in construction and machinery manufacturing.
- Unequal angle steel: Both sides are of unequal length, suitable for special structural designs.
- Miniature Angle Steel (Side length <50mm): Ideal for precision instrument frames and lightweight support structures.
- Standard Angle Steel (50–100mm): Widely used in industrial plant mainframes and medium-scale infrastructure.
- Heavy-Duty Angle Steel (>100mm): Custom-designed for megaprojects like cross-sea bridges.
- Construction Grade: Earthquake-certified for skyscraper steel frameworks.
- Machinery Grade: Surface-hardened for heavy equipment load-bearing components.
- Transportation Grade: Dynamic load-tested for vehicle frame safety compliance.
