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.

Frequently Asked Questions
Q What is the difference between equal angle steel and unequal angle steel?
Equal angle steel has both sides of the same length, making it ideal for symmetrical structural applications such as construction frames and machinery manufacturing. Unequal angle steel has sides of different lengths, providing flexibility for special structural designs where asymmetric load distribution is required.
Q What standard sizes of angle steel are available?
Angle steel is available in a range of sizes: Miniature (side length <50mm) for precision instruments, Standard (50–100mm) for industrial and infrastructure use, and Heavy-Duty (>100mm) for large-scale projects such as bridges. Side lengths typically range from 20mm to 200mm, with thickness from 3mm to 20mm.
Q Which material grade should I choose for corrosion-resistant applications?
For environments with high humidity, chemical exposure, or marine conditions, we recommend the Stainless Steel Series (316L medical-grade), which has passed 3,000-hour salt spray tests. For moderate corrosion resistance with higher strength, the Alloy Steel Series with manganese-vanadium enhancement offers 3x wear resistance.
Q What international standards does your angle steel comply with?
Our angle steel products comply with major international standards including EN10025 (European standard), JIS G3192 (Japanese standard), and GB/T700 (Chinese national standard). We are also ISO9001 certified, ensuring consistent quality management across all production processes.
Q Can angle steel be customized for specific project requirements?
Yes. We offer customized angle steel solutions tailored to your project's load type (static, dynamic, or impact), operating environment (temperature, humidity, corrosion level), and processing method (welding, cold bending, or hot forming). Contact our technical team for a customized catalog and engineering support.
Q How does your manufacturing process ensure dimensional accuracy?
Our high-speed rolling and intelligent cooling technology ensures dimensional accuracy of ±0.1mm and ASTM Class 10+ grain fineness. Our smart production lines also reduce overall manufacturing costs by over 25% compared to traditional methods, delivering both precision and cost-effectiveness.
