Anping Xinye Metal Wire Mesh Products Co., Ltd. is a professional manufacturer with a 5,000–10,000 square meter production base and 51–100 experienced employees. We specialize in producing road safety guardrails that combine structural integrity with practical installation features. This pre-galvanized zinc steel guardrail is rated for a 5.5 kN impact load capacity and supplied in 3.5 m half-lapped spliced sections, making it an effective choice for highways, parking facilities, industrial zones, and rural roads. The product is designed to deliver dependable protection while simplifying shipping, handling, and on-site assembly.
Pre-galvanized zinc steel provides an inherent corrosion-resistant layer that protects the guardrail’s surface during daily exposure to rain, moisture, and UV radiation. Because the zinc layer is applied before shaping, the main body of the guardrail has consistent coating thickness. Cut edges and bolt holes are treated or can be recoated upon request to maintain long-term performance. The half-lapped splice creates a secure connection between adjacent 3.5 m sections, allowing a continuous barrier without unsightly gaps or weak joints.
Key Features and Benefits
- Rated impact resistance: Each section is designed to withstand a 5.5 kN impact load, helping to redirect vehicles and reduce collision severity in low-to-medium speed environments.
- Pre-galvanized material: The zinc-coated steel offers good anti-corrosion performance and reduces maintenance requirements compared with uncoated steel.
- Half-lapped splicing: Overlapping sections allow for quicker alignment, fewer connection points, and improved structural continuity.
- 3.5 m section length: This practical module size reduces the number of joints needed for a given installation area and allows efficient container loading.
- Ready-to-assemble design: Pre-punched holes and standard bolt spacing make field installation straightforward, reducing labor cost.
- Customizable options: Section thickness, hole pattern, coating class, and post accessories are available upon request to fit different project requirements.

Technical Details and Installation Benefits
The 5.5 kN impact load capacity is an important parameter for low-to-medium impact roadside safety. The guardrail system functions by absorbing kinetic energy through the controlled deformation of the rail and its supporting posts. When a vehicle hits the rail, the half-lapped splice transfers strain from the impacted section to neighboring sections, reducing the possibility of a concentrated break. This load-sharing behavior improves overall crashworthiness and helps keep the rail aligned after an accident.
The 3.5 m half-lapped sections are designed with a consistent lapping distance that helps two adjacent rails remain evenly matched. Installers simply overlap the designated lap area and fasten the sections using standard bolts and nuts. The result is a smooth, continuous surface that limits snagging and provides a stable guiding edge. Fewer exposed fasteners also enhance visual appeal. Because the sections are pre-galvanized, they can be stored outdoor for short periods during construction without significant surface deterioration, although proper storage is always recommended.
Applications include highway median and roadside barriers, parking garage edge protection, warehouse traffic separation, and perimeter safety systems. The guardrail sections are compatible with standard steel posts and blockouts, which are also available from our factory. For unusual curves or sloped terrain, the sections can be adapted in the factory to specified angles or lengths. We recommend customers provide detailed drawings so that the holes and splice positions can be arranged to meet site-specific requirements.
Frequently Asked Questions
It means that a single section is designed to resist a peak impact force of 5.5 kilonewtons during normal operating conditions. The actual system performance depends on post spacing, soil strength, and installation quality. Our engineering team can review your specific roadway class and recommend the appropriate configuration.
Yes, the 3.5 m length is our standard production module, but section length, steel thickness, width, and hole patterns are customizable. Contact us with your dimensional drawing or project details, and we will provide a tailored quotation.
Each 3.5 m section has an overlapped end at the splice zone. The installer positions the next section over the first one, aligns the pre-punched holes, and then inserts the supplied bolts or fasteners. This creates a tight, continuous rail connection.
Pre-galvanized steel provides effective corrosion protection in many outdoor conditions. For coastal areas or de-icing salt environments, we can recommend an optional heavy-duty coating or hot-dip galvanizing after fabrication. This is available upon request.
We can supply steel posts, spacer blocks, bolts, nuts, washers, end terminals, and connectors. Please indicate your requirements when making an inquiry so we can bundle the necessary parts.
We provide technical guidance and can share installation drawings depending on the project. For large orders, our sales team works with your contractor to confirm hole alignment, splice orientation, and post anchoring methods.
Yes, sample sections are available. Shipping cost and delivery time depend on the sample quantity and destination. Please contact us to discuss the sample procedure and any required test standards.
