We are a modern high-tech enterprise integrating R&D, production, sales, installation, after-sales service and technical support of highway guardrails. Specializing in providing high-quality and cost-effective highway guardrail products for highway traffic safety and transportation infrastructure projects, we have become an industry benchmark with mature technology, strict quality control and comprehensive services, winning extensive praise and long-term trust from customers at home and abroad.
Our company offers a complete range of products, including W beam highway guardrails (Grade A/B/Am/Bm/SB/SAm), highway anti-collision guardrails, highway median barrier, highway roadside guardrails and other series. The materials include Q235B/Q355B carbon steel, stainless steel, etc. We can customize products with different anti-corrosion processes such as hot-dip galvanizing, spray coating and dip coating according to customer requirements. The galvanized layer thickness can reach more than 85μm, and the spray coating thickness is 60-80μm, with strong adhesion and excellent corrosion resistance, suitable for the complex service environment of highways and extending the service life of products. Our products are widely used in highways, national and provincial roads, urban expressways and other fields. With the advantages of good protective performance, strong impact resistance, easy installation, high strength and excellent cost performance, they have become the preferred guardrail products for various highway traffic infrastructure projects.
In terms of production technology, we adhere to the craftsman spirit of quality and strictly follow national authoritative standards such as GB/T 31439.1-2015 and JT/T 281-2020 to control the product quality throughout the process. Raw materials are selected from high-quality steel plates and square pipe base materials, which are subject to strict physical and chemical inspection before being put into production to prevent unqualified raw materials from entering the production line from the source; The forming process adopts advanced cold bending roll forming technology, and the guardrail plates are processed through multiple processes such as leveling, punching and bending to ensure accurate dimensions and standard radian; The anti-corrosion process adopts hot-dip galvanizing + spray coating double process to ensure no missing plating, no bubbles and no peeling on the guardrail surface; The finished product inspection link implements the double standard of "100% inspection + first article inspection". Each batch of products is tested for anti-corrosion layer thickness, adhesion and mechanical properties to ensure that every highway guardrail leaving the factory meets the highway use standards and quality requirements.
