Frequently Asked Questions (FAQ)
What standards do your road safety guardrails comply with?
Our guardrails comply with major international quality standards including AASHTO M180 (USA), JT/T281-1995 (China), EN ISO1461, and RAL RG620 (Germany), ensuring high reliability and structural performance.
What steel grades are used in manufacturing these guardrails?
We utilize high-quality base steels such as Grade Q235B (equivalent to S235JR and ASTM A283M Gr. D) and Grade Q345 (equivalent to S355JR and ASTM A529M), which offer the ideal balance of rigidity and flexibility for impact absorption.
How thick is the protective zinc coating on the guardrails?
The double-sided hot-dipped galvanized coating ranges from 550g/m² (40µ) to 1100g/m² (80µ) or 1200g/m² (85µ). This heavy coating ensures superior long-term corrosion resistance in harsh outdoor environments.
Can you produce guardrails to custom specifications?
Yes, in addition to our standard sizes (such as lengths of 3200mm to 4320mm), we can manufacture other special specifications and custom profiles based on client requirements, technical drawings, or project designs.
What is the minimum order quantity (MOQ) and payment terms?
Our Minimum Order Quantity (MOQ) is one 20-foot container. We accept standard payment terms including T/T and L/C at sight, and offer flexible trade terms such as FOB, CFR, and CIF.
