Product introduction
Product Overview
Our 76–660mm ERW high frequency welded pipes are professional structural steel tubes specially customized for solar photovoltaic bracket support systems. Adopting mature high-frequency electric resistance welding technology, this series of welded tubes features high structural rigidity, excellent load-bearing capacity, stable welding integrity and outstanding outdoor weather resistance, fully adapting to long-term outdoor wind load, snow load and environmental erosion of solar power station projects.
Manufactured with premium low-carbon structural steel, the ERW solar bracket tubes deliver uniform pipe body texture, strong toughness and excellent anti-fatigue performance. The complete outer diameter range of 76mm to 660mm covers all mainstream specifications for solar panel support frames, photovoltaic bracket columns, auxiliary support beams and power station structural fixing parts. Available with black uncoated, anti-rust oil coating and hot-dip galvanized surface treatment, these structural tubes effectively resist ultraviolet aging, rain corrosion and atmospheric oxidation. With stable mechanical performance and high cost performance, they are the preferred structural support solution for ground solar power stations, rooftop photovoltaic projects and large-scale solar energy engineering worldwide.
Production Process
Structural Grade Raw Material Selection: Adopt high-quality low-carbon steel coils with stable chemical composition and excellent outdoor durability, ensuring long-term load-bearing stability for solar bracket outdoor service.
Precision Coil Slitting: Steel strips are slit into uniform width with strict tolerance control to guarantee consistent wall thickness and balanced force distribution of solar support pipes.
Multi-Pass Cold Roll Forming: Continuous precision rolling forming ensures superior roundness, straightness and smooth surface of pipe blanks, avoiding structural deviation during solar bracket assembly and installation.
High-Frequency ERW Welding: Stable high-frequency induction straight welding forms high-strength, defect-free weld seams. The weld strength matches the base metal completely, ensuring overall structural stability under long-term outdoor wind and pressure load.
Full Internal & External Weld Trimming: All welding beads are thoroughly polished and removed to eliminate stress concentration points, improving anti-fatigue performance and outdoor service life of solar brackets.
Online Sizing & Straightening: Precision dimensional calibration and straightening treatment strictly control pipe tolerance, realizing high-precision matching for solar bracket frame assembly.
100% NDT & Hydrostatic Testing: Each finished pipe undergoes eddy current non-destructive flaw detection and hydrostatic pressure testing to eliminate welding defects and ensure structural safety.
Standard & Custom Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed lengths to adapt to different solar power station layout and bracket design standards.
Weather-Resistant Surface Treatment: Optional anti-rust oil coating for short-term construction and hot-dip galvanized treatment for long-term outdoor anti-corrosion and anti-UV aging.
Structural Performance Sampling Test: Conduct tensile, bending, compression and weather resistance tests to verify load-bearing performance, fully meeting solar power station engineering acceptance standards.
