Product description

Highlights at a glance

  • Adopt ZM275-ZM320 Zn-Al-Mg coating, passed 1008-hour NSS salt spray test. Resist rust in coastal, humid, and saline harsh outdoor environments, greatly cut later maintenance & replacement cost, much longer service life than ordinary galvanized pipes.
  • Customized square/rectangular/round/octagonal tubes, sizes from 40*40 to 200*150, wall thickness 1.5- 5.0 mm. Suitable for aquaculture PV, agrivoltaic, livestock PV, residential solar sunroom, single-axis tracker, and desert ground PV station.
  • Self-owned automatic pipe rolling lines, close to steel mills for stable raw materials; near Huanghua & Yantai seaports with short inland transport, lower export logistics cost, no middleman markup, lower total procurement cost than competitors.
  • Full ISO9001, ISO14001, ISO45001 certificates; products meet EN & ASTM international standards, smooth customs clearance for global export.
  • Multiple tests before delivery: thickness measurement, salt spray, flattening, flaring, NDT, coating mass test. Precise control on straightness, twist & flatness, tiny dimensional tolerance for perfect solar rack installation.
  • Large factory with sufficient production capacity, regular sizes in stock. Optimized production schedule & port logistics to avoid project delay, guarantee on-time construction for PV projects.
  • Yield strength 220-550MPa, tensile strength 300-560MPa, high strength anti-deformation; elongation 14%-20%, withstand wind & snow load for desert, coastal and farm outdoor conditions.
  • Professional R&D team for solar pipes, customize pipe section & coating thickness based on your drawings, terrain and service environment. Full professional service including pre-sales technical selection, in-production tracking and after-sales logistics coordination.
    • Frequently asked questions

    We are a direct manufacturer based in Cangzhou, Hebei. We specialize in Zn-Al-Mg steel tubes for solar mounting systems, including square, rectangular, round and octagonal tubes for ground PV, residential solar, and tracking rack projects.

    Our tubes adopt ZM275-ZM320 Zn-Al-Mg coating and pass the 1008h NSS salt spray test, showing strong resistance to chloride ion corrosion. Perfect for coastal, fish pond and saline land high-corrosion areas, with a much longer service life than normal galvanized tubes.

    Full customization available. Regular stock sizes range from 40*40 to 200*150 with wall thickness 1.5- 5.0 mm. ZM275/ZM320 coating optional, pipe sections adjustable based on project load and environment.

    We hold ISO9001, ISO14001, ISO45001 certificates. Products comply with EN 10219, ASTM A500, EN 10346 international standards. Complete documents support smooth customs clearance worldwide.

    Each batch undergoes thickness test, salt spray test, flattening test, flaring test, NDT and coating mass test. Straightness< 0.1mm/m, twist< 0.1%/m with high precision to ensure easy installation.

    Samples are free; the buyer bears sample freight. Freight cost will be refunded after the bulk order. Send your project drawings for accurate samples & quotation.
