Product introduction
Product Overview
Our 76mm–660mm HFW structural welded steel tubes are specially designed for highway, urban road and traffic safety guardrail engineering. Manufactured with advanced high-frequency straight welding technology, this series of structural pipes features high impact resistance, excellent structural rigidity and stable tensile performance, fully meeting the load-bearing and anti-collision requirements of road guardrail support systems.
Adopting premium low-carbon structural steel, the HFW welded pipe delivers uniform wall thickness, smooth weld seam and high overall stability. The complete outer diameter range covers all mainstream specifications for road guardrail posts, bridge guardrail supports, roadside safety barriers and traffic structural frameworks. Available with black bare finish, anti-rust oil coating and hot-dip galvanized surface treatment, these tubes adapt to long-term outdoor exposure, wind and rain erosion, and vehicle impact working conditions. Factory direct bulk supply provides standardized structural steel pipe solutions for road construction contractors, traffic engineering projects and infrastructure developers worldwide.
Production Process
Structural Steel Raw Material Selection: Adopt high-quality low-carbon hot-rolled steel coils with stable mechanical properties, high toughness and strong impact resistance, complying with road structural steel material standards for traffic facilities.
Precision Coil Slitting: Steel coils are slit into accurate fixed-width strips to ensure consistent wall thickness and symmetrical pipe body structure, avoiding structural deviation affecting guardrail installation stability.
Multi-Pass Cold Forming: Continuous rolling forming process ensures high-precision roundness and straightness of pipe blanks, guaranteeing neat assembly and vertical stress balance of guardrail posts.
HFW High-Frequency Welding: Non-contact high-frequency induction welding forms narrow heat-affected zones and high-integrity welds. The weld strength is equivalent to the base metal, effectively resisting instantaneous impact force from vehicle collision.
Internal & External Weld Trimming: All welding beads are fully polished and removed to eliminate stress concentration points, improving overall structural fatigue resistance for long-term outdoor traffic service.
Online Sizing & Straightening: Strict dimensional calibration and straightening treatment ensure minimal tolerance of pipe diameter, straightness and roundness, matching standard guardrail installation accessories.
Full Non-Destructive Inspection: 100% eddy current flaw detection and hydrostatic pressure testing eliminate internal welding defects, ensuring structural safety of each guardrail steel tube.
Fixed & Standard Length Cutting: Support standard 6m/12m lengths and customized 1.5m–18m fixed cutting lengths to adapt to different road foundation and guardrail height design standards.
Specialized Surface Treatment: Optional anti-rust oil coating for short-term construction use and hot-dip galvanizing for long-term outdoor anti-corrosion, meeting traffic facility durability requirements.
Batch Mechanical Sampling Test: Conduct impact resistance, bending, tensile and flattening tests to verify anti-collision structural performance, ensuring compliance with road guardrail engineering acceptance standards.
