When international buyers source highway guardrails or bridge railings from China, they often have similar questions before placing an order.

At Huiquan Road & Bridge, we’ve collected the most frequent inquiries — and here’s how we answer them clearly and confidently:

1. What materials are used for your guardrails?

We mainly use Q235 / Q345 steel (equivalent to S235 / S355 in Europe).
These materials provide the ideal balance of strength, flexibility, and durability, ensuring the guardrails can effectively absorb impact energy during collisions.

2. How do you protect the guardrails from rust?

All products are hot-dip galvanized after fabrication according to ISO 1461 or EN 1461 standards. The zinc coating thickness is typically ≥ 85 μm (around 600 g/m²), which ensures long-term corrosion resistance even in coastal or humid environments.
Powder coating or paint finishing is also available upon request.

3. Do your guardrails meet international standards?

Yes — our products can be manufactured to meet:

• EN 1317 (Europe)
• AASHTO M180 (USA)
• AS/NZS 3845 (Australia/New Zealand)
  We also provide crash test reports, material certificates, and galvanizing inspection reports for every shipment.

4. How are the guardrails packed for export?

   Safe delivery is just as important as good production.
   Our export packaging includes:
      *Steel or wooden pallets for protection and easy handling
      *Anti-rust wrapping and moisture-proof layers
      *Clear labeling for quick unloading and site identification
      *Efficient container loading to prevent damage and save shipping costs

5. What is your delivery time?

For standard models, production typically takes 20–35 days after receipt of the deposit.
We have strong experience in exporting to Africa, the Middle East, Southeast Asia, and South America — with optimized shipping plans from Qingdao Port.

6. Can you provide installation support?

Yes. We provide installation drawings, on-site guidance (if required), and training materials for local contractors.
We also work with certified installation partners in several countries to ensure the guardrails are properly installed and meet safety standards.

7. What about warranty and after-sales service?

We offer a 12–24 month warranty against manufacturing defects.
In case of any issues, our export team provides quick response, replacement parts, and long-term technical support.

8. Do you accept OEM or customized design?

We can produce customized profiles, post designs, or coating thickness according to client drawings or national standards.
OEM/ODM service is one of our strengths — your logo, packaging, and documentation can all be customized.
