Anping Xinye Metal Wire Mesh Products Co., Ltd is a trusted manufacturer specializing in highway safety systems. Our 3.0mm Zinc Steel W-Beam Guardrail with 80µm zinc coating and 4320mm length is engineered to deliver reliable protection for high-speed roadways. Combining robust material selection with precision manufacturing, this guardrail offers exceptional corrosion resistance and structural integrity, ensuring long-term performance in harsh environments.
The guardrail is made from high-quality zinc steel (Q235 grade), with a thickness of 3.0mm to withstand significant impact forces. The 80µm zinc coating provides superior anti-corrosion protection, extending service life even in coastal or industrial areas. Each section measures 4320mm in length, allowing efficient installation and seamless connection along highways. The W-beam profile is designed according to standard highway safety requirements, effectively redirecting vehicles and reducing collision severity.

Our guardrails undergo rigorous quality control, including tensile strength testing, zinc coating thickness measurement, and dimensional accuracy checks. The hot-dip galvanizing process ensures that the zinc layer bonds metallurgically with the steel, providing cathodic protection even if the surface is scratched. This results in a maintenance-free service life of over 20 years in typical highway environments.

Frequently Asked Questions
-
What is the standard width of the W-beam guardrail?
The standard width is 310mm, which is the typical W-beam profile. However, we can customize width upon request. -
Is the 80µm zinc coating suitable for coastal areas?
Yes, the 80µm hot-dip galvanized coating provides excellent corrosion resistance in coastal and high-humidity environments. For extreme conditions, we offer thicker coatings (e.g., 100µm) as an option. -
How long does the guardrail last before needing replacement?
Under normal highway conditions, the guardrail can last 20–30 years with minimal maintenance, thanks to the zinc coating and robust steel core. -
What posts and blocks are compatible with this guardrail?
This guardrail is compatible with standard W-beam posts (e.g., C-channel or I-beam) and spacer blocks. We can supply matching components if needed. -
Can you provide custom lengths or thicknesses?
Yes, we can manufacture custom lengths (e.g., 4000mm, 4500mm) and thicknesses (e.g., 2.5mm, 4.0mm) based on project requirements. Please contact us for details. -
Do you have certifications for quality control?
We follow internal quality management procedures and can provide test reports for material composition, coating thickness, and mechanical properties. Certifications are available upon request. -
What is the minimum order quantity (MOQ)?
The MOQ is typically 100 pieces, but we can accommodate smaller orders for trial purposes. Please inquire. -
How is the guardrail packaged for shipment?
Guardrails are bundled in steel strapping, with protective wrapping to prevent scratches during transit. Custom packaging (e.g., wooden crates) is available for fragile coatings.
