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 load-bearing structures in construction and machinery. Unequal angle steel has sides of different lengths, offering greater flexibility for special structural designs where asymmetric support is required.
Q
What material grades are available for angle steel, and how do I choose the right one?
We offer Carbon Steel (GB/T700), Alloy Steel (Manganese-Vanadium enhanced), and Stainless Steel (316L). Selection depends on your load type (static/dynamic/impact), operating environment (temperature, humidity, corrosion level), and processing method (welding, cold bending, or hot forming). Our technical team can assist with the best recommendation.
Q
What are the standard size ranges for angle steel products?
Our angle steel products range from a side length of 20mm to 200mm and a thickness of 3mm to 20mm. We categorize them as Miniature (<50mm), Standard (50–100mm), and Heavy-Duty (>100mm) to suit different application scales from precision instruments to large infrastructure projects.
Q
What international standards do your angle steel products comply with?
Our products comply with major international standards including EN10025 and JIS G3192. We are also ISO9001 certified, ensuring consistent quality management across all production processes. Our stainless steel series passes 3,000-hour salt spray tests, and our sustainability practices are ISO14064 certified.
Q
In which industries is angle steel most commonly used?
Angle steel is widely used across multiple industries including construction (steel frameworks, bridges, buildings), machinery manufacturing (equipment and components), transportation (vehicle and ship frames), energy (pipeline supports), and agriculture (greenhouses and livestock fencing).
