Frequently Asked Questions (FAQ)
1. What is the difference between two-wave and three-wave guardrail?
Two-wave (W-beam) is suitable for standard road sections with moderate impact risk. Three-wave (Thrie-beam) has a higher stiffness and is recommended for high-risk areas such as sharp curves, steep slopes, or bridge ends. Both can be supplied in the same outer dimensions.
2. Can the guardrail be customized to different lengths?
Yes, we can produce custom lengths ranging from 2000mm to 6000mm. However, the standard 4320mm is the most common for compatibility with existing posts and accessories.
3. What surface treatment is best for coastal areas?
We recommend hot-dip galvanized (HDG) with a minimum zinc coating of 85µm, which provides excellent resistance to salt spray and humidity. For extremely corrosive environments, additional PVC coating can be applied.
4. How is the guardrail packed for export?
Each guardrail panel is bundled with steel straps, and multiple bundles are stacked on pallets. The entire package is wrapped with waterproof plastic film to protect against moisture during shipping.
5. Do you provide installation accessories like posts and bolts?
Yes, we offer a complete guardrail system including end terminals, reflector posts, bolts, nuts, and washers. All components are designed to match the 4320×310×85mm panels.
6. What is the lead time for a typical order?
For standard specifications (2.5mm thick, HDG), the lead time is 15–20 working days after receiving the deposit. Custom orders may take 25–30 days depending on quantity and complexity.
7. Can you provide third-party testing reports?
Yes, we can arrange for testing by an independent laboratory (e.g., SGS, Intertek) at an additional cost. Standard in-house test reports are provided free of charge.
8. Is the guardrail suitable for use in cold climates?
Q235 steel maintains its mechanical properties down to -20°C. For extreme cold regions (below -30°C), we recommend using low-temperature impact steel (Q345D or Q345E), which we can also supply upon request.
