Dealer buying guide
How US Dealers Can Evaluate an Aluminum Door Supplier
The best comparison is not factory A versus factory B. It is one complete, documented project scope versus another. This checklist helps a small dealer compare quotations without overlooking the items most likely to affect margin and delivery.

1. Start with the project requirement, not a generic price list
Aluminum door pricing changes with size, panel count, system depth, glass, finish, hardware, threshold, screens, quantity and destination. Ask every supplier to quote the same scope. At minimum, send the rough opening width and height, preferred layout, quantity, project city or ZIP code and required date.
2. Confirm which performance documents the project actually needs
A product name or series number does not prove suitability for every US project. Ask the supplier which test reports apply to the exact system being quoted. Provide the project location and requested standard early, then have the documentation checked by the responsible local professional or authority before ordering.
3. Compare the complete quotation
4. Make drawing approval a purchasing checkpoint
The production drawing should capture the agreed dimensions, panel layout, handing, glass, threshold, finish and related screen. Assign one person on your side to review it against the customer order. Any change after approval should be documented before manufacturing continues.
5. Ask for order-specific inspection and packing records
A general factory photo is useful background, but an order record is more actionable. Discuss which checks, assembly steps, labels, packing photos and loading records will be produced for your order. Agree on the evidence you need before shipment.
Dealer FAQ
What should be compared besides the unit price?
Compare the complete specification, included hardware and glass, packing method, documentation, delivery scope, replacement-parts policy and the assumptions behind the quote. A low unit price can be misleading when these items differ.
When should local code requirements be checked?
Before selecting the final system or paying a deposit. Requirements can vary by state, city, exposure and project type. Give the supplier the project location and requested performance standard, then have the applicable documents reviewed by the responsible local professional or authority.
Why is a production drawing important?
The drawing records dimensions, panel layout, opening direction, glass, threshold, finish and other order details. Dealer and supplier can resolve differences before manufacturing instead of after delivery.
How can a dealer reduce replacement-parts risk?
Ask how the supplier records the order, identifies hardware and handles documented after-sales issues. Keep the approved drawing, order reference and photos so the correct component can be identified later.
