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.

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)
As an ISO9001 certified global metals solutions provider, we can offer standard products that comply with EN10025/JIS G3192, providing a full range of solutions for stranded wire, cold headed standards and specialty alloy wire to help our customers reduce costs and increase efficiency.

Frequently Asked Questions
QWhat is the difference between equal angle steel and unequal angle steel?
Equal angle steel has both legs of the same length, making it ideal for symmetrical structural applications such as construction frames and machinery. Unequal angle steel has legs of different lengths, which provides greater design flexibility for special structural requirements where load distribution is asymmetric.
QWhat standard sizes are available for angle steel?
Angle steel is available in a wide range of sizes. Side lengths typically range from 20mm to 200mm, and thickness ranges from 3mm to 20mm. For projects requiring dimensions outside this range, custom fabrication is available upon request.
QWhich material grade should I choose for corrosive environments?
For highly corrosive environments — such as marine, chemical, or outdoor applications — we recommend the Stainless Steel Series using 316L medical-grade material, which has passed rigorous 3,000-hour salt spray tests. For moderate corrosion resistance at a lower cost, the Alloy Steel Series with manganese-vanadium enhancement is also a strong choice.
QDo your angle steel products comply with international standards?
Yes. Our products comply with multiple international standards including EN10025, JIS G3192, GB/T700, and ASTM specifications. We are also ISO9001 certified, ensuring consistent quality management throughout the entire production process.
QCan angle steel be customized for specific project requirements?
Absolutely. We offer full customization services including custom dimensions, material grades, surface treatments, and processing methods such as welding, cold bending, and hot forming. Please contact our technical team with your project specifications to receive a tailored solution.
QWhat are the lead times and minimum order quantities?
