What should a buyer send for an aluminium window quotation from China?
A useful quotation request should identify the project country and city, building type, opening sizes or window schedule, opening methods and approximate quantities. Add any known glass, finish, hardware, screen, packing and delivery preferences. Architectural drawings are helpful, but rough dimensions and marked photos are enough to begin. The supplier should separate confirmed requirements from assumptions and questions, then identify large panels, exposed openings or unusual interfaces that need early review. Price alone is not a complete comparison: the quotation scope should show which frame system, glass build-up, accessories, packing and delivery terms are included. The resulting specification gives the project team a clear basis for engineering, regulatory and installation review.
Buyer decision boundary
Do not treat a rough-size quotation as a final order basis while dimensions, interfaces or delivery scope remain unresolved; local project confirmation is needed before production approval.
Evidence to request or retain
- Dated drawings or schedule with opening marks and quantities.
- Returned scope by opening group.
- Written assumptions and exclusions.
- Packing plan for the receiving location.

Minimum brief versus a quote-ready brief
| Input | Enough to start | Better for comparison |
|---|---|---|
| Openings | Rough width and height | Window schedule with marks and quantities |
| Configuration | Preferred opening type | System, glass, finish, hardware and screens |
| Delivery | Destination city | Target date, trade term and packing notes |
What drawings, schedules or sizes can start a quotation?
A factory quotation can begin from architectural drawings, a window schedule or rough opening width and height. The most useful schedule shows the opening location, floor level, width, height, quantity, opening direction and preferred system type if known.
If the project is still early, do not wait for perfect files. Send the rough sizes and mark which openings are large, exposed, curved, fixed, sliding or regularly operated. That helps the factory separate standard items from openings that need early system review.

A useful schedule connects every opening mark to its size, quantity, floor and opening direction.
Why do building type and destination matter?
Tell the factory whether the project is a villa, apartment, hotel, showroom, coastal home, builder package or replacement job. Destination country, city, floor height, coastal exposure and installation stage help the supplier avoid recommending one generic system for every opening.
A balcony sliding window in a mild inland city, a large living room door near the coast and a high-floor casement window should not be treated as the same buying problem.

Profile, glass build-up, seals and thermal breaks should be named in the quote scope instead of left to assumption.
Which glass, finish and hardware notes should be sent early?
If you already know double glazing, Low-E, laminated glass, acoustic glass, powder coat color, handle color or hardware preference, include it in the first inquiry. If you are unsure, describe the climate, noise, safety or comfort problem you want to solve.
This gives the supplier a useful direction without locking every detail too early. A serious quote should show which parts are fixed, which parts are optional and which items need local project review.
Which delivery and packing details affect the quote?
For overseas projects, delivery target, trade term, container planning and packing expectations affect the final quotation. Clear labels, packing lists and installation references help builders and installers identify each opening after shipment.
If the order will go to a warehouse, builder site or mixed project address, tell the factory early. Packing and labeling should support the receiving process, not become a problem after the goods are finished.

Packing, labels and unloading access belong in the original inquiry because they affect cost and site handling.
