As a leading manufacturer from Anping Xinye Metal Wire Mesh Products Co., Ltd in Hengshui, Hebei, China, we take pride in offering the Corrugated Municipal Guardrail with a thickness of 2.5mm and dimensions of 4320x310x85mm, featuring a 190mm spacing between corrugations. This guardrail is engineered from high-quality galvanized steel to deliver exceptional durability and corrosion resistance, making it an ideal choice for municipal road safety projects. Our product combines robust structural integrity with cost-effective performance, ensuring long-term protection for drivers and pedestrians alike.
The guardrail's corrugated design effectively absorbs impact energy during collisions, reducing vehicle damage and passenger injury. With a standardized 190mm spacing and precise dimensions, it meets common municipal installation requirements and can be easily integrated with existing road infrastructure. Each unit is hot-dip galvanized according to industry standards, providing a uniform zinc coating that withstands harsh weather conditions and extends service life.
Key Features & Benefits
- Robust Material: Made from high-strength galvanized steel (Q235 grade available) with a minimum tensile strength of 370MPa, ensuring reliable performance under impact.
- Optimized Dimensions: 4320mm length, 310mm width, 85mm height – the standard size for W-beam guardrails, compatible with universal posts and connectors.
- Precise Corrugation Spacing: 190mm center-to-center distance between corrugations, designed to maximize energy absorption and deflection control.
- Excellent Corrosion Resistance: Hot-dip galvanized surface (zinc coating weight ≥ 275g/m²) offers long-lasting protection against rust, salt spray, and UV degradation.
- Easy Installation: Pre-drilled holes (optional) and simple bolt-on design reduce labor time and equipment costs on site.
- Low Maintenance: The galvanized finish requires no painting or periodic treatment, lowering total lifecycle costs.
- Customizable Options: Available in different thicknesses (2.0mm, 3.0mm etc.), lengths, and with additional end treatments or reflectors upon request.

The guardrail's W-beam profile is designed to deflect upon impact, guiding the vehicle back onto the road while minimizing sudden deceleration. The 2.5mm thickness provides a balanced combination of strength and flexibility, suitable for medium-speed municipal roads. Compared to thinner gauges, this specification offers enhanced crash resistance without excessive weight, making transportation and handling easier.

Frequently Asked Questions
-
Q: What is the typical installation spacing for the posts?
A: The recommended post spacing is 1.5m to 2m, depending on road curvature and local regulations. Our guardrail is designed to work with standard posts (e.g., 140x4.5mm round posts or 125x125mm square posts). -
Q: Can this guardrail be used on highways?
A: The 2.5mm thickness is suitable for medium-speed roads (up to 70 km/h). For highway applications with higher speed limits, we recommend a thicker gauge (3.0mm or 3.5mm) to meet crash test requirements. Please consult our team for specific project needs. -
Q: How long does the galvanized coating last?
A: In normal atmospheric conditions, the hot-dip galvanized coating can last 15-20 years before any significant corrosion appears. In coastal or industrial areas, the lifespan may be slightly shorter. Regular inspection is recommended. -
Q: Do you provide custom lengths or drilling holes?
A: Yes, we can customize the length (e.g., 3000mm, 4000mm) and pre-drill holes for bolts according to your drawings. Minimum order quantity may apply for custom sizes. -
Q: What is the minimum order quantity?
A: For standard sizes, the MOQ is 100 pieces. For customized orders, MOQ may be 200 pieces. We also accept small trial orders for new customers. -
Q: How is the guardrail packaged for export?
A: Each guardrail is bundled with metal straps, and multiple bundles are stacked on a pallet or placed in a container to avoid bending. We can also use wooden crates for extra protection if required. -
Q: Do you have certificates like ISO or CE?
A: We can provide a factory inspection report and test certificate for the material. Specific certifications like ISO 9001 or CE marking are available upon request, subject to order quantity and audit. -
Q: Can I get a sample before placing a bulk order?
A: Yes, sample orders are welcome. We can send one piece (or a cut piece) for evaluation. The sample cost is charged and will be refunded upon bulk order.
