Welcome to Anping Xinye Metal Wire Mesh Products Co., Ltd., a Hebei-based manufacturer specializing in metal protection solutions for urban and highway infrastructure. Our double-sided municipal guardrail system, featuring a 2.5m rail height and a zinc coating of 600g/sqm, is designed to deliver dependable safety performance on busy city expressways. We manufacture this system in our own 5,000-10,000 square meter facility with the support of 51 to 100 dedicated professionals, ensuring each piece meets strict production standards. With export experience to North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and other regions, we understand the diverse needs of road construction projects worldwide.
The double-sided guardrail is a key component of modern expressway safety systems, especially for central median barriers that must protect vehicles traveling in both directions. Unlike conventional single-sided designs, this system features reinforced steel panels on both sides of the mounting posts, offering balanced impact deflection and preventing vehicles from crossing into opposing traffic. The 2.5m rail height has been selected to provide a sturdy physical barrier that can withstand high-speed collisions while maintaining driver visibility for oncoming traffic and road signs.
All steel components are processed with hot-dip galvanization to achieve a zinc coating weight of 600 grams per square meter. This coating thickness is intended for harsh outdoor environments, including areas where de-icing salts are frequently used in winter. The dense zinc layer acts as a sacrificial barrier, protecting the base steel from corrosion even when surface scratches occur. As a result, the guardrail system maintains its structural strength and visual appearance over a prolonged service life, reducing the need for frequent replacements.
Key Features
- Double-sided protection: Both faces are reinforced, making the guardrail ideal for highway medians and bidirectional traffic separation.
- 2.5m rail height: Provides high containment capacity while remaining suitable for standard roadways.
- 600g/sqm zinc coating: Meets demanding anti-corrosion requirements through a thick, uniform hot-dip zinc layer.
- Modular panel system: Easy to connect, extend, and replace damaged sections without removing the complete barrier.
- Optimized post spacing: Can be customized based on traffic speed and crashworthiness requirements.
- Hollow rail design: Reduces material consumption while maintaining excellent impact resistance.
- Smooth connections: Minimizes snagging points for vehicle tires and improves overall safety.
- Environmentally friendly: Steel is recyclable, and the galvanizing process produces a long-lasting product that supports sustainable infrastructure.

During production, every steel coil is carefully inspected to ensure uniform thickness and acceptable surface quality. The cold-rolling and stamping process creates consistent profiles that meet the required dimensions. After forming, the guardrail panels are cleaned and immersed in a molten zinc bath, resulting in complete coverage of all edges and corners. Our in-house quality team samples each batch to verify the zinc coating thickness and dimensional tolerances. These procedures help guarantee that every shipment behaves reliably in the field.
For city expressway projects, time is often critical. Our guardrail system uses standardized parts and pre-drilled holes, allowing crews to install the barrier quickly with common fasteners. This efficiency reduces traffic closure periods and contributes to lower overall project costs. In addition, the double-sided panels reduce the total number of pieces needed for a median barrier when compared to pairing two separate single-sided systems, further simplifying construction and inventory management.
In terms of maintenance, the 600g/sqm zinc coating dramatically reduces rust-related issues. Even in coastal cities or areas with frequent rain and salt exposure, the guardrail can remain in service for many years with minimal intervention. If a vehicle collision damages a section, the modular design permits simple panel replacement without removing the entire run of guardrail. This practical approach saves municipal budgets and keeps expressways safer and neater.
We also recognize that every expressway has unique conditions, such as variable road curvature, bridge sections, and differing speed limits. Therefore, we offer engineering support to help select the appropriate rail thickness, post type, and connection system. Custom lengths, radii, and end sections are available upon request. For overseas clients, we can pack the system in robust bundles for sea freight, and our location near the ports of Tianjin, Qingdao, and Shanghai enables cost-effective logistics.
Choosing a reliable manufacturer is essential for civic projects. At Anping Xinye Metal Wire Mesh Products Co., Ltd., we combine efficient production with hands-on quality management.

Frequently Asked Questions
1. Is the 2.5m height suitable for all city expressway applications?
The 2.5m rail height is a common choice for central medians and roadside sections where high containment is needed. However, for especially high-risk zones or areas with frequent heavy vehicle traffic, additional reinforcement or specialized crash-rated systems may be considered. We can provide guidance based on your project’s speed limits and barrier requirements.
2. What is the actual meaning of '600g/sqm zinc coating'?
It means that the hot-dip galvanized coating weighs 600 grams per square meter of steel surface. This measurement indicates the thickness and durability of the zinc layer. A higher weight provides better long-term corrosion resistance, which is especially valuable for outdoor installations exposed to rain, snow, and road chemicals.
3. Can the guardrail panels be cut to different lengths?
Yes, we can customize panel lengths to fit your specific drawings. The modular structure allows us to cut or order steel profiles according to project needs. Please provide your required dimensions during the quotation phase so that we can optimize the production plan.
4. How does the double-sided design enhance safety over two single-sided barriers?
Double-sided guardrails are engineered as one integrated unit, sharing the same posts and supporting structure. This creates a continuous load transfer and reduces weak points at the post area. It also uses less material and has a more compact footprint on narrow medians, resulting in better impact stability and reduced installation complexity.
5. What are the maintenance requirements after a collision?
The affected panel can often be unbolted and replaced individually. The galvanized coating will be scraped or damaged at the impact point, and the area may need touch-up zinc paint to maintain corrosion protection. Our modular system simplifies this process so that road crews can restore the barrier quickly.
6. Do you provide installation instructions or technical documentation?
Yes, we can supply general installation drawings, handling recommendations, and connection details with each order. For complex projects, our engineering team can review your designs and suggest configuration adjustments. These documents are provided free of charge with the purchased goods.
7. What is the typical lead time for an order?
Typical production lead time depends on the quantity and custom specifications. For standard sizes, we can usually arrange shipment within a few weeks after order confirmation. We work with your schedule to ensure the products arrive on time for your construction timeline.
8. Can you provide samples before mass production?
Yes, we welcome sample orders to verify quality and dimensions. Please contact us with your expressway project details, and we will recommend the most suitable samples and arrange dispatch. A sample will help confirm fit, finish, and coating quality before you place a bulk order.
At Anping Xinye, we are dedicated to supporting municipal engineering projects with robust guardrail solutions that balance cost, durability, and safety. Since our establishment in 2020, our 5,000-10,000 square meter factory and 51-100 dedicated employees have served customers across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and other markets.
