Anping Xinye Metal Wire Mesh Products Co., Ltd. is a manufacturing enterprise dedicated to the research, production, and sales of metal wire mesh products and traffic safety equipment. Established in 2020, we have rapidly grown into a reliable supplier with a production facility covering 5,000 to 10,000 square meters and a professional team of 51 to 100 employees. Our two-wave municipal guardrail panel is one of the most requested items for road contractors and municipal engineering projects. It is engineered to deliver high-impact resistance, long-term weather endurance, and easy installation, all while keeping project costs under control.
This guardrail panel is manufactured from premium Q235 carbon steel sheet with a nominal thickness of 3 mm. The complete panel is then processed through a hot-dip galvanizing line, producing a dense and uniform zinc coating that protects the metal from rust and environmental corrosion. The two-wave profile, also known as W-beam shape, provides excellent structural stiffness and energy absorption in vehicle collisions. Meanwhile, the 50 mm embedding depth ensures a stable fit with our guardrail posts, reducing the risk of loosening under vibration or repeated impact. All these features make the panel an ideal choice for urban roads, highways, bridges, parking facilities, and residential communities.
Key Features- Premium material: Q235 carbon steel provides high yield strength and excellent impact toughness.
- 3 mm thickness: The thick steel plate enhances the guardrail’s resistance to deflection and penetration.
- Hot-dip galvanized surface: Both sides and cut edges receive a protective zinc layer, which significantly reduces maintenance frequency.
- Two-wave design: The W-beam shape spreads collision force across a larger area and improves deceleration characteristics.
- 50 mm embedding depth: This depth has been tested to provide secure anchoring with standard post systems.
- Corrosion resistance: The zinc coating withstands salt spray, road chemicals, and moisture, making the panel suitable for coastal and cold regions.
- Compatible with standard posts: Our panels fit common W-beam guardrail end posts and splices, simplifying the installation process.
- Customizable sizes: We offer various lengths, radii, and bolt hole patterns to meet project requirements.

Our manufacturing process begins with cutting Q235 coiled steel to required lengths and widths. The blanks are then pressed through a W-beam forming machine to create the double wave profile. Next, precise holes are punched according to the hole pattern. After mechanical cleaning and drying, the panels enter a zinc bath for hot-dip galvanizing. The final step is quality checking and bundling. This controlled process ensures consistent dimensions and surface finish in every batch.
Installation and Maintenance Tips
Proper installation is essential for the guardrail to perform as expected. The recommended post spacing and anchoring depth should be based on the local traffic speed and soil conditions. Our technical team can provide a standard installation drawing to support your crew. After installation, periodic inspection of bolts and the panel position is advised, especially after a collision. Any minor scratches on the galvanized surface can be repaired with zinc-rich paint to retain corrosion resistance. These simple steps will extend the lifespan of the entire guardrail system.
Quality Control
In our factory, every batch of steel sheet must pass chemical composition and thickness checks before production. During stamping, we use calibrated dies to ensure the wave profile is uniform. After galvanizing, the coating thickness and visual appearance are inspected on a sample basis. The final panels are checked for flatness and bolt hole alignment. We guarantee that the products we pack match approved samples and applicable drawings.

Frequently Asked Questions-
What thicknesses are available for the two-wave municipal guardrail panel?
The standard thickness is 3mm, which is suitable for permanent installations. For temporary barriers or lighter applications, 2mm or 2.5mm panels are sometimes used. Heavier thicknesses like 3.5mm or 4mm can be produced on request for high-security zones. -
How does the hot-dip zinc surface affect the service life?
Hot-dip galvanizing forms a metallurgical bond between zinc and steel, which offers outstanding resistance to corrosion. The zinc layer acts as a sacrificial protection when the surface is scratched or cut, so rust is suppressed over a long period. This is especially important for roads that are sprinkled with de-icing salt in winter. -
Is a 50mm embedding depth sufficient for all soil conditions?
The 50mm depth is designed for standard urban road installations. In soft or unstable soil, deeper embedment or a larger post base is recommended. We can offer deeper embedding depths or alternative mounting brackets based on the engineering requirements of your project. -
What lengths can you produce?
We can supply conventional lengths that are typically used on highways. If you need a special length to match your post spacing, we can cut the panel to your specification. Our punching and curving services also allow us to produce panels with a custom radius for road bends. -
Do you provide all necessary mounting hardware?
Yes, we offer matching bolts, nuts, washers, and post connectors as optional accessories. If you have an existing guardrail system, we recommend sending us the drawing so we can check compatibility and supply the correct hole pattern. -
How is the surface protected during sea transport?
The panels are bundled tightly with steel straps and fitted with edge protectors. Additionally, each layer may be separated with plastic spacers to reduce friction. We can also use VCI (Vapor Corrosion Inhibitor) packaging as an optional extra for long-distance shipments. -
Can we get a sample before placing a bulk order?
Samples are available. We can ship a small piece via express courier for your evaluation. The sample cost is usually refundable or deductible from the first production order, depending on the order quantity and arrangement. -
Are custom logos or embossed markings possible?
Yes. Since we are the original manufacturer, we can apply custom labels, paints, or embossed brand marks on the panels. Please confirm the design with our engineering team and allow some preparation time for molds or printing.
