Product Types
Angle steel can be classified based on shape, size, and use:
By Shape:
● 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.
By Size:
● 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.
By Use:
● 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.
Product Advantages
● Mechanical Performance: Unique L-shaped cross-section delivers 40% higher load-bearing efficiency than conventional profiles (lab-verified).
● Cost Efficiency: Smart production lines reduce overall costs by over 25% vs. traditional methods.
● Installation Efficiency: Modular interface design enables rapid assembly, cutting construction time by 50%.
● Sustainability: Full-process green manufacturing with 100% recyclability (ISO14064 certified).
Product Materials
● Carbon Steel Series: GB/T700 compliant, budget-friendly option.
● Alloy Steel Series: Manganese-vanadium enhanced, 3x wear resistance.
● Stainless Steel Series: 316L medical-grade material passes 3,000-hour salt spray tests.
Product Applications
● Construction: Used in steel structures, bridges, and buildings.
● Machinery Manufacturing: Used for equipment, tools, and components.
● Transportation: Used in automotive, train, and ship frames.
● Energy: Used in pipeline supports for oil, gas, and water transport.
● Agriculture: Used in greenhouses and livestock fences.
Process Advantages and Material Selection Guidelines
High-speed rolling and intelligent cooling ensure ±0.1 mm accuracy and ASTM Class 10+ grain fineness. Key selection criteria: Load type (static/dynamic/impact) Operating environment (temperature/humidity/corrosion) Processing method (welding/cold bending/hot forming)
