We are Anping Xinye Metal Wire Mesh Products Co., Ltd, a professional manufacturer based in Hengshui, Hebei, China. Our Thrie Beam Municipal Guardrail (2.5mm thickness, 1850mm length) is designed specifically for highway and municipal road safety. Engineered with high-strength steel and advanced hot-dip galvanizing, this guardrail delivers reliable impact resistance, long service life, and easy installation — making it a trusted choice for infrastructure projects worldwide.
The Thrie beam (three-wave) profile provides superior structural rigidity compared to standard W-beam rails, effectively absorbing and redirecting collision energy. With a thickness of 2.5mm and a standard length of 1850mm, each panel meets the demanding requirements of highway safety barriers. Our production process strictly follows quality control protocols to ensure consistent dimensions, smooth surface finish, and perfect fit with common post systems.

Product Features and Benefits:
- Superior Impact Resistance: The three-wave design increases structural strength, allowing the guardrail to effectively absorb and deflect collision energy, reducing vehicle damage and passenger injury.
- Durable Galvanized Coating: Hot-dip galvanizing provides excellent corrosion resistance, ensuring a lifespan of 20+ years even in harsh outdoor environments.
- Standardized Dimensions: 1850mm length and 2.5mm thickness comply with common international road safety specifications, making it compatible with most existing post systems.
- Easy Installation & Maintenance: Pre-punched bolt holes and simple splice connections allow quick assembly on site, minimizing labor cost and downtime.
- Customizable Options: Available in different steel grades (Q235, Q345), surface treatments (pre-galvanized, painted), and hole patterns to meet specific project requirements.
- Cost-Effective: High strength-to-weight ratio reduces material usage while maintaining safety performance, offering an economical solution for large-scale projects.
Quality Assurance: Every guardrail panel is manufactured under strict quality management. We conduct dimensional checks, coating thickness tests, and tensile strength verification before shipment. Our factory in Hengshui, Hebei, has been producing metal wire mesh and road safety products for many years, serving clients across Asia, Africa, and the Americas.
Frequently Asked Questions:
-
Q: What is the difference between Thrie beam and W-beam guardrail?
A: Thrie beam has three waves (peaks) and is thicker/stronger than W-beam (two waves). It offers higher containment capacity and is often used on highways with higher speed limits or heavy traffic. -
Q: Can this guardrail be used in cold climates?
A: Yes, the hot-dip galvanized coating provides excellent corrosion resistance and the steel material maintains its mechanical properties at low temperatures. However, for extreme cold regions, we recommend Q345 steel for better toughness. -
Q: How is the guardrail installed?
A: The guardrail panels are bolted to steel or wooden posts using standard splice bolts. The posts are typically driven into the ground or embedded in concrete. We provide installation manuals upon request. -
Q: Is the guardrail length exactly 1850mm?
A: The standard length is 1850mm with a tolerance of ±2mm. Custom lengths are available upon request for non-standard spacing. -
Q: What is the minimum order quantity?
A: Our typical MOQ is 100 pieces, but we can accommodate smaller orders for trial purposes. Please contact our sales team for details. -
Q: Do you provide certificates or test reports?
A: Yes, we can provide material test certificates, galvanizing thickness reports, and dimensional inspection reports. Specific certifications can be arranged if required. -
Q: How long does the galvanized coating last?
A: In normal atmospheric conditions, the hot-dip galvanized coating (≥85µm) can protect the steel for 20-30 years before any maintenance is needed. Actual lifespan depends on environmental factors. -
Q: Can I get a sample before bulk order?
A: Yes, sample orders are welcome. The sample cost and shipping will be arranged, and we will refund the sample fee upon bulk order.
