As a direct manufacturer based in Anping, Hebei, Anping Xinye Metal Wire Mesh Products Co., Ltd brings you a robust and dependable zinc steel guardrail engineered to safeguard traffic and infrastructure across demanding environments. Our galvanized steel guardrail is produced within a 5,000 to 10,000 square meter factory facility, backed by a professional team of 51 to 100 employees committed to consistent quality control. This guardrail is designed to deliver long-term corrosion resistance and structural stability, featuring a 25-year coating warranty and a mill test report for full material traceability and performance confidence.
The zinc steel guardrail is a high-strength safety barrier system widely used to protect vehicles from roadside hazards, separate opposing traffic lanes, and define perimeters in industrial zones. Manufactured from quality steel and finished with a protective zinc coating, this guardrail offers an extended service life even in aggressive atmospheric conditions. Each shipment is accompanied by a mill test report, ensuring that every component meets documented chemical and mechanical property specifications.
- Superior Corrosion Resistance: The hot-dip galvanized zinc layer shields the steel core from moisture, salts, and chemical exposure, significantly delaying rust formation in coastal and industrial environments.
- Long-Term Durability: With a 25-year coating warranty under standard service conditions, this guardrail minimizes lifecycle replacement costs and maintenance frequency.
- Verified Material Quality: A mill test report is provided with each batch, allowing buyers to verify the steel grade, zinc coating weight, and relevant mechanical properties before installation.
- High Impact Resistance: The cold-formed steel profile absorbs and distributes collision energy effectively, helping to reduce vehicle damage and passenger injury risk.
- Easy Installation: Standardized post spacing and pre-punched mounting holes allow for rapid assembly with common tools, reducing labor time on-site.
- Customizable Dimensions: Length, height, and post configuration can be tailored to suit various road classifications and safety requirements.

This guardrail system stands out due to its balanced combination of protective longevity and documented consistency. Unlike lower-cost options with unknown steel origins, our mill test report gives engineers and procurement teams clear insight into the actual material performance. The 25-year coating warranty reduces the financial risk of premature corrosion, making this product a sound investment for government road departments, private developers, and industrial facility managers.
The guardrail is engineered to meet the basic requirements of modern roadway safety applications, using established profile geometry and post anchoring methods. Optional powder top coating is available upon request for projects requiring enhanced aesthetics or specific color identification zones.

Q1: What does the 25-year coating warranty cover?
A: The coating warranty covers failure of the hot-dip galvanized zinc layer due to manufacturing defects under standard atmospheric service conditions. It does not cover mechanical damage, improper installation, or exposure to highly acidic or alkaline chemicals.
Q2: What information is included in the mill test report?
A: The mill test report typically lists the steel grade, chemical composition, tensile strength, yield strength, elongation, and zinc coating weight per square meter. This document supports quality verification and engineering review.
Q3: Can the guardrail dimensions be customized for a specific project?
A: Yes, the section length, height, steel thickness, and post spacing can be adjusted according to project drawings. Please share your requirement or typical drawings so we can align production and packaging accordingly.
Q4: How does the guardrail perform in coastal environments?
A: The hot-dip galvanized coating provides significantly better chloride resistance than bare steel. For coastal or high-salinity areas, a thicker zinc coating is available as an optional upgrade.
Q5: Do you provide samples before mass production?
A: Yes, pre-production samples are available. Sample lead time is usually about 5 to 10 working days depending on specification confirmation.
Q6: Which ports are commonly used for export shipment?
A: Our typical export ports are Tianjin, Qingdao, and Shanghai, which offer convenient access to global freight routes for both container and bulk cargo transportation.
Q7: What is the minimum order quantity?
A: The minimum order quantity depends on the specific profile and surface treatment. For standard galvanized guardrail sections, discussions on mixed container loads are welcome to be customized.
Q8: How do you ensure welding or forming quality?
A: Our production line follows standardized die forming and punching steps, with regular dimensional checks. The zinc coating thickness is monitored to ensure it meets the documented requirement.
