Galvanized Steel Pipe
Both hot-dip galvanized and pre-galvanized steel pipes are available. Depending on the application, pipes can be supplied with plain, threaded, grooved, or specially processed ends. Before shipment, each order is checked for outside diameter, wall thickness, length, surface condition, and zinc coating. Mill Test Certificates (MTC) and inspection documents can be supplied with the order when required.
We work with overseas distributors, contractors, fabricators, and project buyers and can handle both regular and customized specifications. Send us the standard, size, wall thickness, length, zinc coating, quantity, and destination port. Our team will check the available production schedule and provide a current galvanized steel pipe price and delivery plan.

Galvanized Steel Pipe Application
FAQ
What is galvanized steel pipe?
Galvanized steel pipe is carbon steel pipe coated with a protective layer of zinc to improve corrosion resistance. It is commonly used in construction, water supply systems, fencing, greenhouse structures, scaffolding, and general fabrication.
What is the difference between hot-dip galvanized and pre-galvanized steel pipe?
Hot-dip galvanized pipe is galvanized after the pipe has been formed, providing zinc protection over the pipe surface and welded area. Pre-galvanized pipe is manufactured from galvanized steel strip and is commonly used for lighter structural and fabrication applications.
What standards are available for galvanized steel pipe?
Galvanized steel pipes can be supplied according to ASTM, BS, EN, DIN, JIS, and GB standards. The appropriate standard depends on the pipe application, dimensions, mechanical requirements, and destination market.
What sizes and wall thicknesses can you supply?
We supply galvanized steel pipes in a wide range of outside diameters, wall thicknesses, and lengths. Round, square, and rectangular sections are available. Custom sizes can also be discussed according to order quantity and production requirements.
Can the zinc coating be customized?
Yes. Zinc coating requirements can be specified according to the application and applicable standard. For outdoor or more demanding environments, a suitable coating level can be selected based on the required corrosion protection.
Can you provide threaded or grooved galvanized steel pipes?
Yes. Depending on the specification, galvanized steel pipes can be supplied with plain ends, threaded ends, grooved ends, or other processing. Please provide your drawing or detailed processing requirements when requesting a quotation.
How do you check galvanized steel pipe quality?
Inspection can cover outside diameter, wall thickness, length, straightness, surface condition, zinc coating, and other requirements specified in the order. Additional testing can be arranged when required by the applicable standard or project.
Do you provide Mill Test Certificates?
Yes. Mill Test Certificates (MTC) can be provided with the shipment for material verification and traceability. Additional inspection documents can be supplied when agreed before production.
How are galvanized steel pipes packed for export?
Galvanized steel pipes are normally packed in export bundles suitable for container loading and international transportation. Packing can be adjusted according to pipe size, shipment method, and customer requirements.
What information is required for a galvanized steel pipe quotation?
Please provide the pipe type, standard, steel grade, outside diameter or section size, wall thickness, length, zinc coating requirement, quantity, and destination port. With these details, we can check production availability and prepare an accurate quotation.
