02 / DEFINE THE CHECKS
Tell us what needs to be verified. Inspection and documentation can be arranged to your order requirements, subject to agreement before production.
Outside diameter, wall thickness, length, end finish and visual condition can be checked against the agreed order specification.
Coating thickness measurements and the agreed sampling method can be arranged. Specify the required internal and external coating criteria when requesting a quote.
Material documentation, mechanical tests, hydrostatic or other applicable tests, and third-party inspection can be discussed before order confirmation. Availability, scope, fees and timing are agreed per order.
Agree test scope, acceptance criteria and required reports before placing the order.
03 / PLAN THE APPLICATION
Start with the intended use, then confirm the right material, dimensions and coating for your project.

For fencing frames, guardrail posts and rails. Share your required outside diameter, wall thickness, length and end processing so the supply specification can be matched to your design.
Discuss your application
For greenhouse structures and agricultural equipment framing. Confirm size, wall and coating grade for the corrosion environment of your site.
Discuss your application
For furniture frames, clothes-drying racks and fitness equipment. The clean pre-galvanized surface takes powder coating and electrophoresis well.
Discuss your application
For storage racking, gates, machinery guarding and general fabrication. Confirm the required finish, joints and fabrication allowance with the order.
Discuss your application04 / PLAN THE DELIVERY
Dispatch timing is confirmed for your order. Quantity, availability, processing and inspection all form part of the schedule.
Agree the size, grade, applicable standard, zinc coating, pipe ends, quantity and inspection requirements.
Your quotation confirms availability, minimum quantity, payment terms, packaging and the estimated dispatch date.
Production or stock preparation and any agreed inspection are scheduled after the order and agreed payment conditions are met.
Bundle packing, end protection, shipment documents and transport arrangements follow the order. Transit time is quoted separately from preparation time.
Steel-strapped bundles are a common packing option. Request end caps, thread protection, bundle identification or additional export packing when enquiring. Packing, shipping terms and documents are confirmed in the quotation.
BEFORE YOU ORDER
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.
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.
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.
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.
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.
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.
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.
Tell us the size, quantity and destination. We will confirm the supply options, inspection scope and dispatch schedule in your quotation.
