Manufacturing & sourcing
A clearer brief. A better window.
Choosing a China window manufacturer starts with matching the proposed system to your building, your market and the responsibilities in your order.
Discuss your requirementsChoose the assembly, then compare the offer.
Two quotations described as “aluminum double-glazed windows” can represent very different products. The profile, thermal break, glass build-up, opening hardware and perimeter details all affect the finished result.
Give each manufacturer the same written brief. Ask them to identify the proposed system, confirm what is included and list any assumptions. A comparable quotation is more useful than a lower figure built around a different specification.
From first drawing
to an agreed order.
A practical sequence for reducing uncertainty before production starts.
- 01
Review the opening schedule.
Check quantities, dimensions, opening directions and locations. Mark where dimensions are preliminary and confirm who will measure and approve the final sizes.
- 02
Agree the technical proposal.
Review frame sections, glass composition, hardware, drainage and fixing interfaces. Ask for applicable test reports and confirm how closely the tested specimen matches the proposed construction.
- 03
Approve the sample and documents.
Where appropriate, review a corner sample, finish sample or full-size mock-up. Record the approved drawings, material selections and any variations in the purchase documents.
- 04
Define inspection and delivery.
Agree inspection points, acceptance criteria, packaging, labels and shipping terms. Confirm the documents needed at destination and the process for reporting transit damage or non-conformity.
Evidence before assumptions
Ask what the documents actually cover.
A test report or certificate should identify the issuer, standard, specimen and relevant conditions. Do not assume that a result for one size, glazing configuration or opening type applies to another. The project designer or responsible local professional should confirm the evidence needed in the destination market.
Manufacturing location alone does not establish quality or regulatory compliance. Written specifications, traceable approvals and an agreed inspection process make the decision more defensible.
