Listings reflect public official-site product evidence and SAMR registry data. We do not certify factory capability, audit production, or guarantee delivery. Confirm specs, MOQ, certifications, and lead time directly with each supplier.
Check the SAMR business scope for aluminium extrusion / manufacturing — not just 'sales' or 'trade'. A genuine mill controls its own die shop, extrusion press and surface-treatment line; an agent resells someone else's. Ask for press tonnage and in-house anodizing/coating evidence.
Treat a generic ISO 9001 logo as table stakes. For a facade or window project, request a project-specific test report (air / water / wind-load and thermal performance) plus a mill test certificate for the exact alloy and temper — not a stock certificate that names no project.
Compare on verifiable signals first: SAMR-registered identity, years in operation, profile-series coverage and export experience. Narrow to a handful, then request samples and quotes in parallel so price and capability are judged side by side.
Common failure modes when sourcing architectural profiles from China, with the mitigations buyers typically use. General industry practice — not a claim about any specific mill.
Mitigation: Specify alloy, temper, coating thickness and tolerance in the PO; require pre-shipment inspection and keep a sealed reference sample to check repeat orders against.
Mitigation: A new die adds production lead time (confirm per order). Lock milestones in the proforma invoice and build buffer into the first run before scheduling repeat orders.
Mitigation: Verify the company on SAMR before paying, use staged payments (deposit, then balance against pre-shipment inspection / B-L), and consider a third-party factory inspection (SGS, Bureau Veritas, Vinacontrol).
Benchmark a quote against today's mill price, then estimate the all-in landed cost to your port before you negotiate. A workable price is a pre-condition for an RFQ — not an afterthought.
You already know the product — use these to confirm a shortlisted mill can actually make what your project needs.
6063-T5 is the workhorse for windows, doors and curtain-wall framing — good extrudability, anodizing and corrosion resistance. 6061-T6 is used for members that need higher structural strength.
Many export-grade mills extrude thermal-break casement and sliding systems comparable to mainstream Vietnamese and European series. Always confirm the exact die profile, gasket and hardware compatibility for your project.
Anodizing, powder-coat (RAL colours), PVDF (Kynar) and wood-grain transfer. Choose by climate, warranty requirement and aesthetic.
For sourcing: match the application to a mill's actual production line — a window-profile specialist isn't automatically a curtain-wall fabricator. Confirm the mill has produced your specific product type before.
For sourcing: ask for the mill test certificate (chemical composition + temper) for the exact alloy — a spec sheet alone isn't proof. Re-melt-heavy mills can drift out of spec batch to batch.
Durable oxide layer; natural silver + bronze/black
RAL colour range; cost-effective for volume
15+ year exterior weathering grade
Heat-transfer film over powder base
For sourcing: finishing (anodizing, PVDF, powder-coat) is often outsourced. Confirm whether the mill coats in-house and to which film/coating-thickness standard — it drives both warranty and weathering performance.
Industry-applicable standards that govern this product type — not a certification claim for any individual mill.
For sourcing: request a project-specific test report against these standards — not a generic certificate. A standard that governs the product type is not proof a given mill's output was tested to it.
Chinese mills supply the bulk of the world's architectural aluminium profiles — window, door, curtain-wall and thermal-break systems in 6063-T5 and 6061-T6, finished in anodized, powder-coat, PVDF or wood-grain. Export-grade mills extrude to your drawings (casement, sliding and system windows, facade framing members, sun-shading louvres) and can match mainstream Vietnamese and European profile series. Sourcing direct from a SAMR-registered mill rather than a trading layer cuts cost and gives you a verifiable factory identity, mill test certificates and project test reports on request. Use the supplier shortlist to compare architectural profile mills and send one RFQ.
Send one RFQ; we review your request and can help arrange an introduction to SAMR-registered profile mills that match your alloy, finish and volume.
