| Parameter | Value |
| Material | ASTM A36 Mild Steel |
| Tensile Strength | 400–550 MPa |
| Yield Strength | ≥250 MPa |
| Leg Width | 20mm – 200mm (customizable) |
| Thickness | 3mm – 20mm |
| Length | 6m, 12m, or as per customer request |
| Surface Finish | Hot Rolled, mill finish (can be primed/painted) |
Product Advantages for Municipal Guardrail Applications
- High Strength-to-Weight Ratio: The ASTM A36 grade provides sufficient load-bearing capacity while keeping the weight manageable for installation and transportation.
- Excellent Weldability: Ideal for on-site welding to assemble guardrail sections, posts, and connections.
- Good Formability: Can be easily cut, drilled, and bent to meet specific design requirements.
- Cost-Effective: Low-carbon steel offers an economical solution without compromising structural performance.
- Corrosion Resistance: When properly painted or galvanized after fabrication, it provides long service life in outdoor environments.
- Uniform Dimensions: Precise hot-rolling process ensures consistent leg lengths and thicknesses, reducing installation errors.
Our angle bars are extensively used in municipal guardrail systems, including highway median barriers, sidewalk railings, bridge parapets, and temporary traffic control barriers. The product meets the mechanical requirements of ASTM A36, which is widely accepted in construction and civil engineering projects globally.
We also offer value-added services such as custom cutting to length, drilling of mounting holes, and surface treatment (e.g., hot-dip galvanizing, painting) to match your project specifications. Our team ensures that each batch is inspected for dimensional accuracy and surface quality before shipment.

Frequently Asked Questions
Q1: What is the difference between ASTM A36 and other steel grades?
A: ASTM A36 is a low-carbon steel with moderate strength and excellent weldability, making it ideal for general structural applications like guardrails. Higher grades (e.g., A572) offer higher strength but may be less cost-effective for this use.
Q2: Can you supply angles with pre-drilled holes for guardrail assembly?
A: Yes, we can drill holes according to your drawings or industry standards. Please specify hole diameter, spacing, and position when ordering.
Q3: Is hot-dip galvanizing available?
A: Yes, we offer hot-dip galvanizing as an optional surface treatment to enhance corrosion resistance. Please note that galvanizing will add to the total lead time.
Q4: What is the minimum order quantity?
A: For standard sizes, the minimum order quantity is 1 ton. For customized dimensions, it may vary. Contact our sales team for details.
Q5: Do you provide mill certificates?
A: Yes, we can provide mill test certificates (MTC) for each batch to confirm compliance with ASTM A36 requirements.
Q6: How long does delivery usually take?
A: For stock sizes, delivery takes about 15–20 days after deposit. For custom orders, it may be 25–30 days depending on quantity and processing.
Q7: Can the angle bar be used for load-bearing structures besides guardrails?
A: Absolutely. ASTM A36 angle bars are commonly used in steel frames, brackets, supports, and other structural applications. However, always verify with a structural engineer for critical loads.
Q8: Do you offer samples before bulk order?
A: Yes, we can provide small samples (e.g., 30cm length) for evaluation. The sample cost is negotiable, and shipping is at the customer's expense.
*Note: All technical data are typical values and may vary within standard tolerances. For precise specifications, please refer to the mill certificate.
