Aluminum windows and doors from Foshan: where a small buyer should start
This site turns public supplier listings, technical references and documented trade practice into buying checklists. It is built for importers, renovators and small online sellers who need to ask better questions before paying a deposit.
Start with the decision, not the catalogue. Choose a finished window or door if you need an installed product; choose the profile guide if you are buying upstream material. Then use the RFQ, inspection and landed-cost guides to compare suppliers on the same basis.
Product guides
Six product categories, each with different RFQ fields and inspection risks. A sliding window and a thermal-break casement are not interchangeable quotations.
- Aluminum WindowHow to specify, verify and compare finished aluminum windows from Foshan without treating listing prices or platform badges as proof.
- Aluminum DoorA practical guide to buying finished aluminum doors from Foshan, covering thresholds, hardware, destination evidence and quote comparison.
- Thermal Break Aluminum WindowWhat a thermal break does, which strip and glazing details to specify, and how to check whole-window evidence before buying from Foshan.
- Aluminum Sliding WindowSliding-window specification, track and roller checks, drainage, and a dated public listing sample that is not a quotation.
- Aluminum Casement WindowCasement and awning window specification: hinges, friction stays, wind load, egress, drainage and the evidence to request from Foshan suppliers.
- Aluminum Window ProfileBuying extruded aluminum window profiles from Foshan: alloy and temper, die ownership, wall thickness, finish, tolerance and mill evidence.
Where the supply chain sits
Foshan is a prefecture-level city in Guangdong. Dali is a town in Nanhai District within Foshan, not a separate city. Public sources describe Dali's aluminum extrusion cluster; they do not prove that any particular seller owns a factory there.
- FoshanHow Foshan's districts, supplier types and public evidence fit together for an overseas buyer of aluminum windows and profiles.
- DaliDali is a town in Nanhai District, Foshan, described as an aluminum extrusion cluster. What is documented, what is not, and how to verify a seller.
Process guides
RFQ, inspection, MOQ, shipping, landed cost and platform comparison. The guides deliberately avoid universal MOQ or price ranges.
- Aluminum Window RFQA repeatable RFQ process for aluminum windows: one drawing, one destination requirement, one quote format and a written evidence gate.
- Aluminum Window InspectionA preshipment inspection sequence for aluminum windows and doors: documents, dimensions, operation, finish, evidence and packing.
- MOQ for Aluminum WindowsHow to compare MOQ figures for aluminum windows when suppliers quote pieces, sets, square metres or tonnes, and why a headline MOQ is not a category norm.
- Shipping Aluminum WindowsPacked dimensions, crating, LCL versus FCL, Incoterms and damage prevention for aluminum windows shipped from China.
- Aluminum Window Landed CostBuild a landed-cost model for aluminum windows from China: quote basis, freight, insurance, duties, taxes, port charges, delivery, installation and spares.
- Alibaba vs Made-in-ChinaA dated, scope-limited comparison of Alibaba.com and Made-in-China for aluminum window sourcing, including what could not be reviewed.
Terms that change a quote
Short explanations of the labels buyers see in listings, and the evidence to ask for instead of trusting the label alone.
- Thermal BreakA plain-English explanation of thermal breaks in aluminum window frames, the labels suppliers use, and the evidence a buyer should request.
- Aluminum ExtrusionHow aluminum extrusion works, what die, alloy, temper and tolerance labels mean, and what to verify when buying window profiles from Foshan.
- 6063 T5 vs T6The difference between 6063-T5 and 6063-T6 for window profiles, with sourced reference values and the checks a buyer should add.
- Powder Coating vs AnodizingHow powder coating and anodizing differ, what their labels do and do not prove, and which finish questions to put in a Foshan profile RFQ.
How this edition was researched
The first edition uses desk research: public supplier profiles, manufacturer catalogues and general technical references. Each page separates source-backed statements from editorial recommendations and records the exact claim behind a factual sentence. One Alibaba supplier profile was accessible on 10 November 2026; a Made-in-China showroom returned HTTP 403 and a manufacturer PDF could not be machine-read, so neither is used as proof of capability.
No price range is presented as a market norm. One dated listing sample is retained on the sliding-window page because its scope and missing data can be inspected; it is not a quotation. MOQ is handled the same way. Where no comparable sample exists, the page says Not verified.
No local visits, interviews or factory audits have been conducted for this edition. The local field-note modules therefore render an explicit empty state rather than a story.
