Aluminium Window RFQ Checklist for Builders and Project Buyers

An RFQ should begin with project country, city, building type, buyer role and approximate timeline. A villa owner, builder, showroom and importer may need different quote detail even when the window sizes look similar.

This context helps the factory decide how much detail to include in the first reply. A buyer comparing systems needs explanation. A repeat importer may need clearer scope, packing and trade term structure.

The strongest RFQ includes plans, elevations and a window schedule. If those are not ready, rough opening sizes and photos are enough for a first review. The factory needs width, height, quantity, opening type and any large-panel notes.

Do not send only a catalogue image and ask for the best price. A supplier cannot responsibly choose frame depth, glass or hardware without opening information.

The RFQ does not need final engineering decisions, but it should state the desired direction: casement, sliding, lift-slide, tilt-turn, folding, sunroom, thermal break, non-thermal, double glazing, Low-E, laminated glass, screen and hardware finish.

If you are unsure, say what problem you want to solve: heat, noise, safety, large opening, coastal exposure, easier maintenance or budget control. That creates a better supplier conversation.

For overseas orders, packing and delivery affect the real project cost. State whether you expect FOB, CIF, LCL, full container, warehouse delivery, site delivery or staged shipments. Mention whether labels should match the window schedule.

A quote that ignores packing can look cheaper at first but become harder to use later. Builders need to receive, identify and move the goods smoothly.

When replies arrive, check whether each supplier quoted the same sizes, glass, color, hardware, screen, packing and trade term. Also check whether they asked useful questions. A detailed question often means the supplier saw a real project issue.

A fair comparison is not the lowest number in isolation. It is the clearest scope at a price that matches the system and delivery reality.

If you ask three suppliers with three different messages, the replies will be difficult to compare. Use one RFQ format: project context, drawings or sizes, opening type, glass target, color, hardware, screen, packing, delivery term and questions to answer.

Then compare the replies line by line. The better supplier usually makes assumptions clear, asks about missing details and separates optional items instead of hiding everything inside one total number.
