Welcome to Anping Xinye Metal Wire Mesh Products Co., Ltd, a trusted manufacturer based in Hengshui, Hebei, China, specializing in high-quality metal safety solutions. Our ASTM A36 Steel Municipal Guardrail with Zinc Coating (2.5mm Thickness) is engineered to deliver superior strength and corrosion resistance for urban and highway environments. This guardrail is the ideal choice for municipalities seeking cost-effective, long-lasting road safety barriers that meet strict ASTM standards.
With over years of experience in metal fabrication, we ensure every guardrail section is precision-formed from ASTM A36 steel — a structural carbon steel known for its excellent weldability and mechanical properties. The 2.5mm thick base material provides robust impact resistance, while the hot-dip zinc coating offers exceptional protection against rust and weather extremes. Whether you are upgrading a city street, constructing a new highway, or securing a parking lot, our guardrail delivers reliable performance and easy installation.
Key Features & Technical Specifications
- Material: ASTM A36 structural steel — ensures high tensile strength and ductility.
- Zinc Coating: Hot-dip galvanized (average coating weight ≥ 275 g/m² per ASTM A123) — provides long-term corrosion resistance.
- Thickness: 2.5 mm (±0.1 mm) — optimal balance between strength and weight.
- Standard Compliance: Manufactured to ASTM A36 and AASHTO M180 specifications for road barriers.
- Design: Corrugated beam profile (W-beam or Thrie-beam options available) for effective energy absorption.
- Mounting: Pre-drilled bolt holes for quick connection to posts and splices.
- Length Options: Customizable from 3m to 6m per section; standard 4m widely used.
- Height: Available in 0.6m, 0.8m, and 1.0m; suitable for various road classes.

Frequently Asked Questions
-
Q: What is the difference between W-beam and Thrie-beam guardrail?
A: W-beam has a single corrugation and is lighter, suitable for lower speed roads. Thrie-beam has three corrugations, offering higher strength for high-speed highways. Both are available in ASTM A36 with zinc coating. -
Q: How long does the zinc coating last?
A: Under normal atmospheric conditions, the hot-dip galvanized coating can protect the steel for 20–30 years before needing maintenance. In coastal or industrial areas, the lifespan may be shorter; we recommend a thicker coating if required. -
Q: Can I get custom lengths or hole patterns?
A: Yes, we offer customization. Standard lengths are 3m, 4m, and 6m, but we can cut to any length. Bolt hole positions can be adjusted per your design drawings. -
Q: Is this guardrail compatible with standard posts?
A: Yes, our guardrail uses standard bolt spacing compatible with most common post systems (e.g., C-channel, I-beam). We can also supply matching posts and hardware upon request. -
Q: Do you provide test certificates?
A: Yes, we can provide mill test certificates for the steel (ASTM A36) and galvanizing reports. Please inquire for specific documentation. -
Q: What is the minimum order quantity?
A: Typical MOQ is 100 meters (approx. 25 sections of 4m). For smaller projects, please contact us to discuss possibilities. -
Q: How is the guardrail packaged for shipping?
A: Sections are bundled with steel strapping, protected with plastic wrap or tarps for sea freight. Each bundle is clearly labeled with dimensions and quantity.
