Anping Xinye Metal Wire Mesh Products Co., Ltd, based in Hengshui, Hebei, China, proudly presents our ASTM A36 Hot Rolled Mild Steel Angle Iron — a premium choice for municipal guardrail applications. With years of experience in metal fabrication and a commitment to quality, we supply angle iron that combines strength, durability, and cost-effectiveness. Our product is engineered to meet the rigorous demands of public infrastructure, ensuring safety and longevity in every project.
This angle iron is manufactured from ASTM A36 mild steel, a widely recognized standard for structural carbon steel. The hot-rolled process ensures a uniform microstructure and excellent weldability, making it ideal for guardrail posts, brackets, and frames. Whether you are constructing highway barriers, pedestrian guardrails, or bridge railings, our angle iron provides the reliable performance required for municipal applications.
Below we detail the key features, technical specifications, and benefits of our product, followed by a comprehensive FAQ section to address common buyer inquiries.
Key Features & Technical Specifications
- Material Grade: ASTM A36 – ensures consistent mechanical properties and compliance with international standards.
- Manufacturing Process: Hot rolled – provides a smooth surface, precise dimensions, and improved ductility.
- Cross-Section: L-shaped (equal or unequal legs) – offers high structural stability for guardrail mounting.
- Dimensional Range: Leg lengths from 20 mm to 200 mm, thickness from 3 mm to 20 mm, and lengths up to 12 meters (customizable).
- Surface Options: Black (mill finish), hot-dip galvanized, or painted (e.g., powder coating) – corrosion resistance tailored to local environments.
- Weldability: Excellent – suitable for field welding and fabrication without preheating for most thicknesses.
- Load-Bearing Capacity: High tensile strength (400–550 MPa) and yield strength (≥250 MPa) ensure long-term performance under traffic loads.
- Certifications: Compliant with ASTM A36 standard; mill test certificates available upon request.

Frequently Asked Questions (FAQ)
Q1: What is the difference between ASTM A36 and A572 angle iron?
A: ASTM A36 is a mild steel grade with a minimum yield strength of 250 MPa, while A572 offers higher strength grades (e.g., 345 MPa). For guardrail applications, A36 is often sufficient and more cost-effective. Our A36 angle iron is widely used in municipal guardrails due to its good weldability and ductility.
Q2: Can you provide galvanized angle iron for guardrails?
A: Yes, we offer hot-dip galvanized surface treatment as an option. Galvanization provides excellent corrosion resistance, making it ideal for outdoor and coastal environments. Please specify your requirement when placing an order.
Q3: What are the standard lengths available?
A: Standard lengths are 6 meters, 9 meters, and 12 meters. Custom lengths can be produced upon request, subject to minimum order quantities.
Q4: Do you provide mill test certificates?
A: Yes, mill test certificates (MTC) complying with ASTM A36 are available upon request. They verify the chemical composition and mechanical properties of the steel.
Q5: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is typically 5 tons. For customized sizes or special surface treatments, MOQ may vary. Please contact our sales team for details.
Q6: How do you ensure the angle iron meets the ASTM A36 standard?
A: We source raw materials from reputable steel mills and conduct in-house tests including tensile, yield, and elongation tests. Third-party inspection is also available at the buyer’s request. Each batch is traceable and documented.
Q7: Can this angle iron be used for highway guardrail posts?
A: Absolutely. ASTM A36 angle iron is commonly used for guardrail posts, blockouts, and rail brackets. Its strength and weldability make it suitable for absorbing impact energy in roadside safety systems.
Q8: What is the delivery time for a typical order?
A: For standard sizes and quantities, delivery is usually within 15–25 working days after order confirmation. Larger or customized orders may require additional time. We strive to meet your project schedule.
