Galvanized pipe, also known as galvanized steel pipe, is a pipe coated with zinc layer on the surface of welded steel pipe, galvanized pipe is divided into hot galvanized pipe and cold galvanized pipe two main types. Hot dip galvanized pipe is formed by dipping the steel pipe into molten zinc, this treatment can produce a thick and uniform coating, with strong adhesion and long service life.

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 (average coating ≥275g/㎡). 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.
