Dali, Foshan Aluminum Supply Chain: A Research-Based Buying Guide
Dali 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.
Decision summary. Dali is a town in Nanhai District, Foshan, not a separate city. Public references describe it as an aluminum extrusion cluster, but this edition found no government or association statistic to quantify that claim and no verified factory address.
What Is Documented About the Cluster?
Dali is a town in Nanhai District, Foshan, Guangdong, located north of central Foshan. Public reference material describes the town as mainly known for its aluminum extrusion industry. That sentence is a useful lead, but the entry is an encyclopedia summary and the industry statement is not backed by an inline statistic.
This edition therefore treats Dali as a documented place with a plausible extrusion cluster, not as a measured market. It does not state the number of extruders, employment, output, export share or the current status of any market. A supplier's presence in Dali is a claim to verify, not a fact established by the town's reputation.
Profiles, Finished Windows and Trading Businesses
The Dali cluster is upstream: extrusion, dies, finishing and profile supply. Finished-window fabrication and export trading can be nearby or elsewhere in Foshan. A seller's address in Dali does not tell you whether it extrudes, coats, fabricates or simply sources. The distinction changes the questions you ask and the evidence you require.
Extrusion and Surface Finishing
Extrusion pushes heated aluminum through a die to form a profile; finishing then applies an anodized oxide layer or a powder-coated film. These are separate capabilities with separate quality risks. A profile can be dimensionally correct and still fail a finish requirement, or carry a good finish on a poorly extruded section. Ask which plant performs each step, request the die number and the finish specification, and keep the certificates with the lot.
Fabrication and Export Supply
If you are buying finished windows, the important site is the fabricator that cuts, machines, assembles, glazes and packs. It may buy profiles from a Dali extruder and hardware from other suppliers. Ask for the fabrication address, the inspection plan and the name of the legal entity that signs the contract. A showroom in a profile market is not proof of a fabrication line.
How to Build a Supplier Shortlist
Build the shortlist from the operation you need. For profiles, ask for die number, alloy, temper, wall thickness, finish and mill certificate. For finished windows, ask for the fabrication address, the model-specific report and the packing plan. Then compare candidates on the same drawing and the same evidence list.
Do not use a town reputation as a substitute for a company check. Do not treat a marketplace badge as a factory audit. A shortlist should record what was checked, when, by whom and what remains unknown.
Planning a Market or Factory Visit
No market name, street address or appointment is confirmed for this edition, so no route is published. Public map pins and showroom photos are not enough to establish a production site. If you plan a visit, ask for the address in writing, confirm the production lines that will be visible, and record the date and scope of what you actually observed. A short visit is evidence of a location at a moment, not a capability audit.
Address status. Not verified. No street address or market opening detail is confirmed for this edition.
Reference coordinates 23.1119, 113.1047 (from the cited place record; not a factory location).
No confirmed appointment, opening-hours or access note has been recorded.
Local Field Notes
This edition is based on public sources. Local market visits and factory observations have not yet been added. No first-hand visit, interview or quotation record is presented as evidence on this page.
Sources, Methodology and Research Limits
This page separates published source material from editorial recommendations. Supplier descriptions are treated as claims, not as verified capabilities. The research record below lists what was checked for Dali.
Claims used on this page
public sourceverifiedDali is a town in Nanhai District, Foshan, Guangdong, at approximately 23.11194 N, 113.10472 E.
Dali, Guangdong — Lead section and coordinates
Limits: Coordinates refer to the town, not to a market entrance or factory; The page is an encyclopedia entry and should be checked against an official administrative source.
public sourceverifiedWikipedia's Dali entry describes the town as mainly known for its aluminium extrusion industry; this is an encyclopedia summary, not a government or association statistic.
Dali, Guangdong — Economy section
Limits: The sentence is not supported by an inline citation on the encyclopedia page; It does not quantify the number of firms, employment, output or current activity; It cannot be used to claim that a particular supplier owns a factory in Dali.
analysisverifiedA public supplier profile can show a Foshan name and product range without documenting factory ownership, production capacity or the specific production site for an order.
Forge Windows and Doors (FoShan) Co., Ltd. supplier profile — Profile header and overview
Dali, Guangdong — Economy section
Limits: This is an evidence-reading rule, not an accusation about any named company; A factory audit or business licence check could close the gap; neither was performed for this edition.
public sourceverifiedNo market visit, factory audit, interview or sample inspection was conducted for this edition; the published pages are based on desk research.

WANJIA high-end door and window product guide (PDF) — Manufacturer PDF review status
Limits: The record documents absence of field research; it does not claim that no field evidence exists anywhere; Future visits must be recorded separately with observer, date, scope and permission.
public sourceverifiedExtrusion pushes material through a die to create a fixed cross-section; aluminum is the most commonly extruded metal and can form complex profiles.
Extrusion — Lead section and Materials section
Limits: General process description, not a supplier capability or tolerance statement; Die design, press size and alloy determine what a specific plant can produce.
analysisverifiedPowder coating adds a polymer film, while anodizing converts the aluminum surface into an oxide layer; a finish label alone does not establish film thickness, adhesion, colour fastness or whole-window performance.
Powder coating — Lead section and Methodology section
Anodizing — Aluminium section and Sealing section
Limits: Comparative explanation, not a claim that one finish is better for every climate or budget; Finish performance also depends on pretreatment, application quality and maintenance.
public sourceverified6063 is described as the most common alloy used for aluminium extrusion and is used for window and door frames; it is heat treatable and suitable for anodizing.
6063 aluminium alloy — Lead section and Uses section
Limits: Encyclopedia summary; alloy selection depends on the structural requirement and applicable standard; Other alloys such as 6061 or 6082 may be specified where higher strength is needed.
analysisverifiedA supplier certificate or platform badge does not show that the tested model, size and glazing configuration match a buyer's destination requirement; the report scope must be checked.
