Anping Xinye Metal Wire Mesh Products Co., Ltd, located in the renowned wire mesh industrial base of Hengshui, Hebei, China, is proud to present our premium Hot Dip Galvanized Municipal Guardrail with a thickness of 2.5mm made from Q235 steel, specifically designed for highway and municipal road safety applications. This guardrail combines exceptional strength, superior corrosion resistance, and cost-effective durability, making it an ideal choice for high-speed roads, urban expressways, and critical infrastructure projects. Our years of manufacturing expertise ensure that every panel meets stringent quality standards, delivering reliable protection for both drivers and pedestrians.
In modern traffic engineering, safety barriers must withstand severe impacts while resisting environmental degradation. Our guardrail, manufactured from high-quality Q235 steel and protected by a hot-dip galvanized coating, provides a robust solution that significantly reduces maintenance frequency and extends service life. The 2.5mm thickness ensures excellent rigidity without excessive weight, facilitating easy installation and transportation. Below, we detail the key features, technical specifications, and benefits that make this product a preferred choice for contractors and government agencies worldwide.
Key Features & Advantages
- Superior Corrosion Resistance: The hot-dip galvanizing process (zinc coating thickness ≥ 85μm) creates a metallurgical bond that protects the steel from rust, even in harsh coastal or industrial environments. This ensures a service life of 20–30 years with minimal maintenance.
- High Strength & Impact Resistance: Q235 steel offers excellent tensile strength (375–500 MPa) and yield strength (≥235 MPa). Combined with 2.5mm thickness, the guardrail can absorb and redirect impact energy from vehicles, reducing accident severity.
- Precision W-Beam Design: The classic W-beam profile optimizes structural rigidity and energy dissipation, meeting international road safety standards. The corrugation pattern also helps prevent vehicle underride and redirects errant vehicles safely.
- Easy Installation & Customization: Standard lengths of 4320mm and heights of 310mm are available, but we also offer custom sizes and post spacings to fit specific project requirements. All components (rails, posts, blocks, bolts) are supplied for quick assembly.
- Cost-Effective Lifecycle: The hot-dip galvanized coating eliminates the need for frequent repainting or replacement, reducing long-term ownership costs. The guardrail's durability also minimizes traffic disruption during maintenance.
- Environmentally Friendly: Zinc is a natural element and fully recyclable. The manufacturing process adheres to green production standards, and the product itself requires no harmful paint or chemical treatments.

Detailed Product Benefits
Enhanced Safety for Highways: The guardrail's W-beam shape is engineered to redirect vehicles at angles up to 15°, preventing dangerous rollovers and head-on collisions. The 2.5mm thickness provides the necessary stiffness to resist deformation, while the galvanized coating ensures that the barrier remains effective even after years of exposure to rain, snow, and road salt.
Low Maintenance & Long Life: Unlike painted barriers that require frequent touch-ups, hot-dip galvanizing offers a self-healing protection. If the coating is scratched, the surrounding zinc sacrificially corrodes to protect the steel. This reduces maintenance costs by up to 50% over the product's lifespan. Our guardrail is designed to perform reliably for 20+ years in most climates.
Versatile Application: Whether for expressways, urban arterial roads, bridge approaches, or parking lot perimeters, this guardrail adapts to various configurations. We provide matching end terminals, offset blocks, and post types (e.g., I-beam, C-channel) to suit different soil conditions and impact severity levels.
Quality Assurance: Every production batch undergoes rigorous testing for zinc coating thickness, adhesion, and mechanical properties. Our factory is equipped with advanced galvanizing lines and tensile testing machines, ensuring consistent quality from raw material to finished product.
