Round steel tube, roll-formed from pre-galvanized steel strip — a welded tube. If your project references a standard, send the standard number and sizes; we review feasibility with the factory and confirm before quoting.
Outside Diameter (OD)
Per order — common NPS or metric size series can be followed on request.
Wall Thickness
0.6 – 2.5 mm standard; other thicknesses on request.
Steel Grade
State your required grade. Grade, dimensions and supply conditions are confirmed together for each order.
Zinc Coating
Z40 / Z60 / Z80 (40 / 60 / 80 g/m²) standard; other coating weights can be requested. Acceptance criteria and coating measurements are agreed before order confirmation.
Length
6 m is a common enquiry length. Requests for 12 m or cut lengths are reviewed against size, quantity and transport requirements.
Pipe End Finish
Plain, beveled or threaded ends with couplings can be requested. Specify thread requirements and confirm processing availability in the quotation.
Surface Finish
Clean pre-galvanized surface, suitable for powder coating, electrophoresis or wrapping; surface condition and acceptance requirements agreed per order.
Manufacturing Standard
Specify the requested dimensional series and sizes. We review feasibility with the factory and confirm in writing before quoting — we do not claim compliance we cannot evidence.
Application
Furniture frames, fencing and guardrails, greenhouse structures, clothes-drying racks, fitness equipment frames, storage racking, gates and general light fabrication.
MOQ
From 1 ton — sized for trial orders and market tests.
Lead Time & Shipment

BEFORE YOU ORDER

Useful answers.

Are all listed sizes in stock?

The size information is an enquiry reference, not a stock list. Please send the required outside diameter, wall thickness and quantity so we can confirm availability and the applicable supply standard.

Is your tube hot-dip galvanized or pre-galvanized?

Our tube is roll-formed from pre-galvanized steel strip — the strip is zinc-coated before forming. Standard classes are Z40/Z60/Z80 (40/60/80 g/m²). If your application needs a heavy post-galvanized coating, send the requirement and we confirm feasibility honestly before quoting.

Is the tube seamless?

No — and we say so. Tube rolled from strip always has a weld seam. Ours is a welded tube; seam appearance and treatment can be discussed for your application.

Can you quote other standards or sizes?

Yes, send the standard and exact outside diameter × wall thickness. Other sizes and special lengths are reviewed individually, and dimensions must be matched to the specified standard.

Can tests or third-party inspection be arranged?

Inspection can be arranged according to the order and customer requirements, subject to prior agreement. Specify the test method, acceptance criteria, sampling, required reports and inspection party before order confirmation.

What is the lead time and minimum order quantity?

MOQ is from 1 ton per order — sized for trial orders and market tests. Standard walls are ready in about 1 week. Every order gets a confirmed production and delivery schedule in writing with the quotation.

Can the pipe be used for water or fire-protection systems?

Please provide the intended service, design pressure and project requirements. Material, coating, testing and any required approvals must be agreed for that application; the size guide alone does not establish suitability.
