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.
