Galvanized steel pipe provides reliable corrosion protection through a hot-dip or electro-galvanized zinc coating, making it ideal for outdoor, industrial, and structural applications. Available in round, square, and rectangular profiles, these pipes combine durability with cost-effectiveness for use in construction frameworks, fencing, handrails, water supply systems, and electrical conduits.
Manufactured to international standards including ASTM A53, ASTM A500, EN 10219, and JIS G3444, our pipes offer consistent wall thickness, smooth surfaces, and strong weldability. Custom lengths, diameters, and coating thicknesses are available, with full certification and packaging suitable for export.
Suitable for projects requiring long-term performance in exposed environments, galvanized steel pipe delivers strength, corrosion resistance, and value in a versatile steel solution.

Our galvanized square pipes are crafted from premium carbon steel (Q235B, A36), featuring a uniform zinc coating for long-lasting rust resistance. Available in hot-dip galvanized (HDG) and electro-galvanized (EG) options—HDG with thick metallurgical bonding coating for outdoor/heavy-duty use (construction frames, scaffolding), EG with smooth thin coating for indoor scenarios (furniture, railing). Covering seamless and welded types, they come in standard square sizes with precise right-angle tolerance, supported by MTC compliant with ASTM A500, BS EN 10219, and GB/T 3094.


Our galvanized pipe products cover both seamless and welded types, all manufactured through automated production lines with precision processing. Seamless pipes are formed through hot-rolling piercing and cold-drawing processes, followed by high-temperature hot-dip galvanizing (zinc temperature accurately controlled at 450-465°C) to achieve metallurgical bonding between the zinc coating and base metal. Welded pipes are formed via high-frequency welding (ERW) technology, integrated with online eddy current weld inspection and internal blowing/external scraping processes to ensure uniform zinc coating. The entire production line is equipped with laser diameter measurement systems (tolerance ±0.15mm), real-time zinc coating thickness monitoring, and dual passivation treatment. Compliant with ASTM, JIS, EN, and other international standards, we provide galvanized pipe solutions with strong corrosion resistance, high dimensional accuracy, and suitability for demanding applications worldwide.


In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.


Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
