Product sourcing guide
Sourcing Aluminum Casement Windows from Foshan
Casement and awning window specification: hinges, friction stays, wind load, egress, drainage and the evidence to request from Foshan suppliers.
Decision summary. Casement windows project outward and depend on hinge or friction-stay quality, wind load and a clear opening direction. Specify the handing, stay limit, egress requirement, screen and drainage before comparing quotes.
Is This Product Suitable for Your Business?
Casement windows provide good ventilation and a relatively tight seal when closed, but an open sash projects into the facade and can be affected by wind. They suit projects where the opening direction, cleaning access and screen strategy have been thought through. Large or high-level sashes need hardware rated for the leaf weight and wind exposure; a small sample window does not prove that the largest size will perform.
| Fit | Buyer type | Reason |
|---|---|---|
| Unknown — not verified | Amazon FBA | Inbound eligibility and consumer installation support were not verified for projecting windows. |
| Conditional | Shopify | Requires accurate site measurement and installation support; returns are costly once a custom sash is made. |
| Conditional | Small importer | Suitable for projects with a fixed opening schedule and a local installer who can adjust hinges and restrictors. |
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
Draw the elevation from inside and outside, mark the hinge side and opening direction, and state the clear opening required for ventilation or egress. Record the leaf width and height, glass weight and expected wind load. Confirm whether the quote includes the friction stay or hinge, the restrictor, the handle, the screen and the sill detail.
Frame, Profile and Thermal Break
Specify the profile series, alloy and temper, wall thickness and reinforcement. Outward-opening sashes transfer wind load to hinges and the frame, so reinforcement and hinge fixing details matter. If a thermal break is required, confirm that the break is continuous around the opening and that the hinge screws do not bridge it. State the frame depth and the rough opening.
Glass, Hardware and Opening Configuration
Record glass build-up, weight, edge clearance and whether safety glazing is required. Specify hinge or friction-stay model, restrictor, handle, lock and screen. State the maximum opening angle and whether the window must remain open at a limited position. For top-hung windows, confirm the stay and the cleaning position. Ask how the sash is supported during installation.
Destination-Market Performance Evidence
Ask for evidence that covers the opening type, sash size, glass and hardware. Casement performance is sensitive to sash size and hinge position, so a report for a small fixed window is not enough. If the project requires egress, fall protection or a specific wind-load class, state it and ask for a model-specific report or calculation. A local code professional should confirm the requirement.

Where Foshan and Dali Fit in the Supply Chain
Casement fabrication is a downstream operation that combines extruded profiles, hinges, seals and glass. Dali's documented cluster role is upstream extrusion. Ask whether the seller fabricates the window or buys completed units, and name the production site in the contract. The Dali guide distinguishes cluster evidence from a supplier's own claims.
What Public Listings Reveal About MOQ and Pricing
Casement listings commonly quote a frame rate or a per-square-metre rate without the hinge model, glass package, screen or restrictor. Those differences change both price and safety. This edition collected no configuration-complete casement sample, so no price range is shown and MOQ is marked Not verified. Compare quotations only after the drawing and hardware schedule are fixed.
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.
Not verified. No dated MOQ sample was collected for this product category. MOQ can be quoted per piece, per set, per square metre, per kilogram or per tonne; confirm the unit, the model scope and whether a sample order is available in writing.
Supplier Verification and Inspection Checklist
Inspection should include full-travel operation, hinge fixing, restrictor function and a check that the sash does not strike the frame or the wall. For large or high windows, confirm the installation and safe-cleaning plan.
Before Paying a Deposit
Approve an elevation with handing, opening direction, restrictor position and screen. Confirm the hinge or stay model and its rated leaf weight. Ask for the fixing detail and the maximum permitted sash size. Confirm the legal entity, production address and the party responsible for replacement hardware.
Before Shipment
Open and close every sash through its full travel, check the restrictor and lock, and inspect hinge fixings for movement. Confirm that the sash clears the frame and that drainage is unobstructed. Photograph the hinge detail and the packing. Check that the glass does not bear on the frame and that the edge clearance matches the glazing detail.
Inspection checkpoints
- Hinge or stay fixingpreshipment
- Risk: Insufficient fixing or reinforcement can let the sash drop or pull out under wind load.
Verification: Check screw length, reinforcement and movement at every hinge; confirm the hardware rating against the sash weight. - Full-travel operation and restrictorpreshipment
- Risk: A sash that binds or opens beyond its intended limit is a safety and weather risk.
Verification: Operate the sash through its full travel and verify the restrictor, lock and handle function. - Handing and opening directionsample
- Risk: A mirrored sash cannot be corrected on site without a remake.
Verification: Compare the hinge side with the approved elevation marked inside and outside. - Drainage and weather sealpreshipment
- Risk: Outward-opening sashes can trap water at the bottom rail if drainage is wrong.
Verification: Check drain slots, seal continuity and the sill detail against the system drawing. - Model-specific performance evidencerfq
- Risk: A small fixed-window report does not cover a large projecting sash.
Verification: Match the report to the opening type, size, glass and hardware being shipped.
Common pitfalls and checks
- Specifying the sash before the wind loadrfq
- Risk: A large sash with light hardware may be unsuitable for an exposed facade.
Verification: State the design pressure and confirm the hardware and reinforcement are rated for it. - Adding a screen after the window is maderfq
- Risk: Screen tracks and fixings may conflict with the sash or the opening limit.
Verification: Freeze the screen type and fixing detail before fabrication. - Ignoring safe cleaning accessproduction
- Risk: Outward-opening sashes on upper floors may be difficult or unsafe to clean.
Verification: Confirm the cleaning position, restrictor and any fall-protection requirement with the project designer.
Shipping, Replacement Parts and Total Cost
Projecting sashes increase the packed depth and the risk of hinge or handle damage. Ask for packing that protects the hardware and for a loading plan that does not put weight on the sash. Keep spare handles, restrictors and hinge components. The shipping guide explains the packed-dimension and freight questions to ask.
Questions to Send Your Supplier
Send the elevation, the hardware schedule and the destination requirement in one package. Require the supplier to state the maximum sash size covered by its hardware and test evidence.
Prepare your RFQ. Send one drawing, one schedule and one destination. Ask every supplier to answer in the same units and to state exclusions.
