Anping Xinye Metal Wire Mesh Products Co., Ltd., located in the heart of China's wire mesh industry in Hengshui, Hebei, brings you a premium solution for highway safety: the Hot Dip Galvanized Zinc Steel Guardrail made from Q235 steel with a thickness of 2.0mm, strictly manufactured according to ASTM A123 standard. This guardrail combines exceptional strength, corrosion resistance, and durability to protect roads, bridges, and highways effectively. With years of experience in metal fabrication, we ensure every piece meets international quality requirements, giving you peace of mind in traffic safety projects.
Our guardrail is engineered to absorb impact energy and redirect vehicles safely, reducing the risk of severe accidents. The hot-dip galvanized coating provides a long-lasting barrier against rust and environmental wear, even in harsh climates. Below, we detail the key features and technical specifications that make this guardrail a reliable choice for contractors, government agencies, and infrastructure developers.
Key Features & Benefits
- Superior Material Quality: Made from Q235 steel, known for its excellent tensile strength and weldability, ensuring structural integrity under high impact.
- Robust Galvanization: Hot-dip galvanized coating per ASTM A123 provides a uniform zinc layer (average 85-100 microns) for exceptional corrosion resistance. Tested to withstand 500+ hours in salt spray without red rust.
- Optimal Thickness: 2.0mm thickness offers a balance between strength and weight, meeting highway safety standards for both passenger cars and heavy trucks.
- Standard Compliance: Manufactured strictly to ASTM A123, ensuring consistent quality, dimensional accuracy, and performance. Also compatible with AASHTO M180 specifications.
- Easy Installation: Pre-punched holes for standard bolts and post connections, reducing on-site labor and installation time. Customizable lengths and hole spacing available upon request.
- Low Maintenance: The galvanized coating eliminates the need for painting or regular anti-corrosion treatment, saving long-term maintenance costs.
- High Visibility: Silver-gray finish provides high contrast against road surfaces, enhancing driver visibility, especially at night or in low light.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between hot-dip galvanizing and electro-galvanizing?
A: Hot-dip galvanizing (used in our guardrail) involves immersing steel in molten zinc, creating a thicker, more durable coating (typically 50-100 μm) compared to electro-galvanizing (10-20 μm). The hot-dip process provides superior corrosion resistance, especially for outdoor applications like highways. -
Q: Is this guardrail compliant with AASHTO M180?
A: Yes, our guardrail is manufactured to meet both ASTM A123 and AASHTO M180 standards. The dimensions, materials, and galvanizing requirements are compatible. Please confirm specific project requirements with our sales team. -
Q: Can the guardrail be cut to custom lengths?
A: Absolutely. We offer custom lengths to fit your project layout. Standard lengths are 4.0m, 4.5m, and 6.0m, but we can produce any length up to 12m upon request. -
Q: What is the typical lead time for an order?
A: For standard sizes and quantities, lead time is approximately 15-20 days after order confirmation. Custom orders may require additional time depending on the specifications. We recommend contacting us early to schedule production. -
Q: How do I install the guardrail? Do you provide installation instructions?
A: Yes, we provide detailed installation guidelines and technical drawings for each order. The guardrail is designed for easy bolting to standard highway posts (e.g., W6x9 or S3x5.7). Pre-drilled holes ensure quick alignment. -
Q: What is the warranty on this product?
A: We offer a limited warranty against manufacturing defects in materials and workmanship. The galvanized coating is warranted against flaking or peeling under normal conditions. For specific warranty terms, please refer to our sales contract or contact us. -
Q: Can you supply samples for testing?
A: Yes, we can provide small samples (e.g., 1-meter piece) for quality evaluation. Shipping cost is at the buyer's expense. Please submit a sample request through our sales team. -
Q: Is the guardrail available in Thrie-beam design?
A: Yes, we offer both W-beam and Thrie-beam profiles. Thrie-beam is recommended for higher containment levels (e.g., for truck barriers). Please specify your requirement when ordering.
