Product introduction
Product Title
76~660mm ERW Pipe Bridge Guardrail Supporting Steel Pipe / Highway Safety Railing Structural Steel Tube
Brief Introduction
76~660mm ERW Bridge Guardrail Supporting Steel Pipe is a specialized structural steel tube designed for highway, municipal and bridge safety protection systems. Manufactured by advanced high-frequency electric resistance welding technology, this ERW structural pipe features uniform wall thickness, precise dimensional tolerance, stable overall rigidity and excellent impact resistance. As the core load-bearing and fixing component of bridge guardrails, road safety railings and anti-collision protection structures, it can effectively resist vehicle impact, wind load and long-term outdoor fatigue load.
Available in outer diameter from 76mm to 660mm with customizable wall thickness and surface treatment, the pipe fully meets national and international structural standards such as EN 10219, ASTM A500 and GB/T. It supports hot-dip galvanizing, anti-rust painting and other surface treatments to adapt to outdoor open-air, high humidity and coastal corrosive environments. Widely used in bridge guardrail posts, highway safety barrier supports, overpass protection structures and municipal road railing systems, this ERW structural pipe is the most cost-effective and reliable solution for traffic safety infrastructure projects.

Production Process & Structural Performance
1. High-Quality Structural Raw Material Adopt qualified hot-rolled steel coils with stable chemical composition and excellent low-temperature toughness. Strict raw material inspection ensures the finished pipe has strong impact resistance and fatigue resistance, fully adapting to long-term outdoor traffic load and wind vibration environment.
2. Precision Continuous Forming & ERW Welding Multi-pass progressive rolling ensures uniform pipe roundness and consistent wall thickness. High-frequency welding without filler metal forms integrated weld structure. Online inner and outer scarfing removes welding flash, making the weld surface completely flush with the pipe body, avoiding local stress concentration of guardrail supports.
3. Online Weld Normalization Treatment The key process for structural guardrail pipes. Online heat treatment eliminates welding residual stress, balances the mechanical performance of weld and base metal, ensuring the pipe will not crack or deform under sudden vehicle impact and long-term alternating load.
4. Customized Surface Protection According to outdoor engineering requirements, the pipes can be treated with anti-rust primer or hot-dip galvanizing. The compact protective layer effectively isolates ultraviolet radiation, rain erosion and atmospheric oxidation, greatly improving outdoor service life of bridge and highway guardrail structures.
5. Full-Range Quality Testing 100% online ultrasonic weld flaw detection, hydrostatic pressure test, tensile and bending mechanical test, dimensional tolerance inspection. All pipes meet structural safety standards for traffic infrastructure before delivery.
Key Product Advantages
✅ High Structural Safety Uniform wall thickness + integrated weld structure + stress relief treatment, excellent anti-impact and anti-deformation performance, suitable for traffic safety protection structures.
✅ Accurate Dimensional Consistency Strict tolerance control ensures perfect matching with guardrail accessories, post bases and connecting parts, improving overall installation flatness and structural stability.
✅ Superior Outdoor Weather Resistance Supports multiple anti-corrosion treatments to adapt to open-air bridges, highways, coastal humid and high-salt environments, avoiding rust and structural aging.
✅ Flexible Processing & Construction Easy to cut, weld, bend and drill on site. Suitable for various guardrail modeling and on-site adaptive construction, greatly improving project progress.
✅ High Cost Performance Stable batch quality, low defective rate and long service life, effectively reducing later maintenance and replacement costs of traffic infrastructure projects.
