- 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
What is the difference between equal and unequal angle steel?
Equal angle steel has both sides of the same length and is widely used in general construction and machinery manufacturing. Unequal angle steel has two sides of different lengths, making it suitable for special structural designs that require asymmetric load distribution.
What materials are available for angle steel, and how do I choose the right one?
Angle steel is available in Carbon Steel (GB/T700, cost-effective), Alloy Steel (manganese-vanadium enhanced, 3x wear resistance), and Stainless Steel (316L grade, corrosion-resistant). Selection depends on your load requirements, operating environment, and budget. Our technical team can assist with customized recommendations.
What are the standard size ranges for angle steel?
Angle steel side lengths typically range from 20mm to 200mm, with thickness ranging from 3mm to 20mm. Miniature sizes (<50mm) suit precision frames, standard sizes (50–100mm) fit industrial structures, and heavy-duty sizes (>100mm) are used in large-scale infrastructure projects.
What international standards does your angle steel comply with?
Our angle steel products comply with multiple international standards including EN10025 (European), JIS G3192 (Japanese), and GB/T700 (Chinese). We are also ISO9001 certified, ensuring consistent quality across all product lines.
Can angle steel be customized for special project requirements?
Yes. We offer full customization services including custom dimensions, material grades, surface treatments, and certifications. Whether you need earthquake-certified construction-grade steel or dynamic load-tested transportation-grade profiles, our engineering team can provide tailored solutions.
Is your angle steel environmentally friendly and recyclable?
Absolutely. Our angle steel is manufactured through a full-process green production system and is 100% recyclable, certified under ISO14064. Our smart production lines also reduce manufacturing costs by over 25% compared to traditional methods, benefiting both the environment and your project budget.
