Applications

Where galvanized pipe is used

If your project is one of these, tell us which — it decides the wall class and the zinc coating we recommend.

WA

Water supply & plumbing

Medium and heavy wall pipe, threaded with couplings, for building water lines and risers.

SC

Construction & scaffolding

48.3 mm and other scaffold sizes for frames, guard rails and access platforms.

AG

Greenhouse & agriculture

Light wall round and square tube for greenhouse frames, irrigation lines and livestock structures.

FE

Fencing & gates

Square and rectangular tube for fence panels and gate frames, with a coating that tolerates weather.

HV

HVAC & air ducts

Round pipe for ducting runs and supports, cut to length for fabrication in your workshop.

FP

Fire protection & structure

Pipe for fire lines and structural framing where a zinc coating is specified.

How it works

From your size list to a loaded container

Send the list

Diameter, wall thickness, length and quantity — a photo of a handwritten list is fine. Add the standard you buy to if you have it.

We confirm and quote

You get the price, the zinc coating and wall thickness we will supply, the lead time and the loading port — normally within 24 hours.

Production, photos, loading

Goods are bundled, capped and marked; you receive photographs of the bundles and the container loading before the vessel sails.

Packing & loading

Bundled, capped and photographed

Every shipment is photographed from the bundle to the container, so you know exactly what left the yard.

Terms

FOB, CFR and CIF from Tianjin or Qingdao. Delivered terms quoted when your project needs them.

Marking

Size, wall thickness and heat number marked on the bundle tag and stencilled on the pipe where required.

Documents

Mill certificate stating the zinc coating, packing list, invoice, bill of lading and certificate of origin.

Buyer questions

FAQ

What do you need to give me a price?

Four points: diameter (or DN / inch size), wall thickness, length, and quantity. If you do not know the wall thickness, tell us the application — water line, scaffold, greenhouse frame — and we will recommend it.

Is the pipe hot-dip galvanized or pre-galvanized?

Both are available. Hot-dip galvanized pipe has a heavier coating and is specified for outdoor and wet service; pre-galvanized pipe is made from zinc-coated coil and suits dry, indoor work at a lower cost. Tell us the application and we will quote the right one.

Can the ends be threaded?

Yes. Threads are cut to ISO 7/1 or NPT as you specify, gauged before packing, and protected with plastic caps. Couplings can be fitted to one end of each length.

What is the minimum order?

Mixed container loads are normal — pipe plus fittings. Trial quantities are accepted so you can check the thread, the coating and the packing before a project order.

How is the coating verified?

The zinc coating mass is stated on the mill certificate, and coating thickness can be checked with a magnetic gauge by your inspector or ours before loading. Photographs of the test are provided on request.

Do you supply fittings with the pipe?

Yes — elbows, tees, couplings, nipples and caps in matching galvanized finish, packed inside the same container so nothing is missing on site.
