Sourcing Aluminum Windows from Foshan
How to specify, verify and compare finished aluminum windows from Foshan without treating listing prices or platform badges as proof.
Decision summary. Finished aluminum windows are made to a dimension schedule. Compare suppliers only after one drawing, one glass build-up, one hardware schedule and one Incoterm are fixed. Public listing prices are not comparable quotations, and this edition publishes no category price range.
Is This Product Suitable for Your Business?
Finished aluminum windows are made to a dimension schedule, so the buying decision starts with who will measure, install and handle warranty. A small importer with a contractor or installer in the destination market can make custom windows work. A Shopify seller shipping single units to consumers faces packing, damage and installation risk. An Amazon FBA seller must treat inbound eligibility, oversize handling and after-sales parts as unverified until the marketplace and carrier confirm them.
The table below is an editorial judgement, not a platform eligibility decision.
| Fit | Buyer type | Reason |
|---|---|---|
| Unknown — not verified | Amazon FBA | Inbound eligibility, oversize handling and return or installation support have not been verified for this category. |
| Conditional | Shopify | Possible for made-to-measure orders when the seller controls packing, freight and installation support; consumer damage claims remain a material risk. |
| Conditional | Small importer | Workable with a local installer and an approved drawing; requires factory verification, preshipment inspection and a spare-parts plan. |
Fit labels are editorial judgements based on customization, shipping, installation and after-sales constraints. They are not platform eligibility decisions.
Specifications to Include in Your RFQ
A window quotation is comparable only when every supplier prices the same drawing. Use a dimension schedule with location, quantity, opening direction and elevation; attach the architectural drawing where one exists. Ask each supplier to quote the same unit, quantity and Incoterm, and to state what the price excludes.
Frame, Profile and Thermal Break
Specify the alloy and temper, the profile system or drawing reference, the required wall thickness, and the thermal-break material and geometry. Do not accept "standard aluminum" as a specification. Profile wall thickness is one input to structural and durability assessment, not a standalone quality grade; installed performance also depends on reinforcement, hardware, glass and workmanship.
Glass, Hardware and Opening Configuration
Record the glazing build-up (glass type, thickness, cavity, spacer, coating and gas only if actually specified), the hardware schedule, and the opening direction as seen from inside or outside. Confirm screen, sill, drainage, handles, locks, hinges or rollers, and whether anchors and installation accessories are included. Ambiguous handing is a common source of remake cost.
Destination-Market Performance Evidence
Ask for reports that name the tested model, dimensions, glass build-up and hardware configuration, and ask which test method and laboratory issued them. A CE, UKCA or other mark on a profile or company page is not the same as a model-specific report. The importer remains responsible for confirming the destination's applicable requirements with a qualified local professional.

Blank values are intentional. They must come from the buyer's drawing, the destination requirement or a supplier's written quotation; this site does not fill them with invented specifications.
Where Foshan and Dali Fit in the Supply Chain
Foshan is a prefecture-level manufacturing city in Guangdong; Dali is a town in its Nanhai District. Public supplier profiles often present extrusion, finishing, fabrication and trading together, but these are different operations. A showroom address, a platform badge or a company name containing "Foshan" does not prove that the seller owns the plant that will make the order.
Read the Dali supply-chain guide for the cluster context, and put the production address and legal entity in the contract.
What Public Listings Reveal About MOQ and Pricing
Public pages show prices per square metre, per piece or per set, often before glass, hardware, crating and freight are defined. This edition records only samples whose date, unit and missing data can be inspected. It does not average them or label the result a market price. If no comparable sample exists for a category, the page says Not verified.
One supplier FAQ observed on 10 November 2026 states an MOQ of 100 units per model. It does not define the model, size or configuration, and it cannot be applied to another supplier.
Not verified. No dated, like-for-like price sample was collected for this product category. Public listings often show a price per square metre, per piece or per kilogram without a comparable specification. Ask for a quotation against the same drawing, quantity and Incoterm.
| Observed | Quantity | Scope |
|---|---|---|
| 10 November 2026 | 100 pieces | Supplier FAQ states 100 units per model; model, size and configuration are not defined and the statement covers one supplier only. |
Supplier Verification and Inspection Checklist
Verification has two stages: identity and capability before money moves, then conformity before shipment. The checklists below are recommendations for the buyer's process, not a finding that any named supplier is deficient.
Before Paying a Deposit
Confirm the legal entity name, bank account name, production address and the person authorised to sign the contract. Ask for a business licence, the profile system drawings and a model-specific test report. Approve a drawing that fixes dimensions, handedness, glass, finish, hardware, packing and acceptance criteria. Pay only against a contract that names the product, quantity, price basis, Incoterm, delivery scope and remedy for nonconformity.
Before Shipment
Inspect before crating and before the balance payment becomes unconditional. Check dimensions against the approved schedule, operate every opening type, inspect finish under consistent light, verify glass and hardware markings, and confirm that agreed tests were performed on the agreed configuration. Photograph packing, corner protection, labels and container loading. Record defects and the correction deadline in writing.
Inspection checkpoints
- Dimensions against the approved schedulepreshipment
- Risk: One incorrect width or height can make a unit unusable on site and expensive to return.
Verification: Measure every unit and compare it with the approved schedule before packing; record the measurement method and tolerances. - Handing and opening directionsample
- Risk: A mirrored sash or wrong hinge side may only be discovered at installation.
Verification: Operate every unit and compare the handing with the approved elevation marked inside/outside. - Glass and glazing build-uppreshipment
- Risk: A different spacer, coating or glass thickness changes performance, weight and price.
Verification: Check glass labels, spacer markings and the report against the ordered configuration; photograph each marking. - Finish, seals and drainagepreshipment
- Risk: Scratches, colour variation and blocked drainage paths lead to claims after installation.
Verification: Inspect under consistent daylight, check drain slots and weep holes, and compare finish against an approved sample. - Hardware operationpreshipment
- Risk: Binding hinges, stiff rollers or misaligned locks may indicate frame distortion or poor assembly.
Verification: Operate every opening at least five times, check lock engagement and record any noise, binding or alignment issue. - Packing and corner protectionpreshipment
- Risk: Sea freight and multiple handling events cause frame and glass damage when crating is inadequate.
Verification: Photograph crates, corner protection, internal blocking, labels and the loading plan before the container is sealed. - Report scope matches the orderrfq
- Risk: A generic certificate or a report for another size does not demonstrate the ordered configuration.
Verification: Match model, dimensions, glass, hardware and test method in the report to the approved drawing. - Replacement parts routeaftersales
- Risk: Proprietary rollers, handles or gaskets can be difficult to source after the project closes.
Verification: Ask for a spare-parts list, part numbers, minimum quantities and the lead time for a repeat order.
Common pitfalls and checks
- Comparing a price per square metre without the same scoperfq
- Risk: Glass, hardware, finish, crating and freight can change the effective cost more than the quoted frame rate.
Verification: Re-quote every supplier against one drawing, quantity, Incoterm and inclusion list. - Treating a platform badge as an order guaranteerfq
- Risk: A verified profile does not prove that the ordered model or destination documentation is correct.
Verification: Ask for the production address, model-specific reports and an inspection plan in addition to the badge. - Paying a deposit before drawing approvalsample
- Risk: Once cutting starts, a dimension or handing error is difficult and costly to reverse.
Verification: Make deposit release conditional on a signed, dimensioned drawing and a sample or first-article check.
Shipping, Replacement Parts and Total Cost
Windows are bulky, fragile and project-specific; freight is rarely a simple per-unit number. Ask for packed dimensions and gross weight per unit, crating method, container loading plan and the freight basis. Clarify who supplies replacement glass, rollers, handles, hinges and gaskets after arrival, and whether those parts are standard or proprietary. The shipping guide and landed-cost guide show which cost lines to collect.
Questions to Send Your Supplier
Send the same question set to every candidate and require written answers. A supplier who cannot answer the evidence questions is not automatically unsuitable, but the gap must be priced and managed before the order is placed.
Prepare your RFQ. Send one drawing, one schedule and one destination. Ask every supplier to answer in the same units and to state exclusions.
