For developers & contractors
Window and Door Supply for Building Projects
Start with a coordinated opening schedule rather than a model name alone. Match each opening to its size, quantity and project requirements, then discuss the configuration and quotation scope with EOUXIN. Shipping, installation and regulatory requirements need to be agreed for the particular project.
Build one coordinated project brief
An opening ID is the link between the plan, elevation, quantity schedule and later configuration discussions. Use the same IDs across documents, include the drawing revision and separate alternatives from the base request.
Project context
Country and city, building use, procurement role, project stage and intended destination.
Opening schedule
IDs, widths and heights with units, dimension basis, quantity, opening direction and viewing side.
Configuration & requirements
Preferred systems, glazing, finish, hardware, screens and any required performance evidence.
Scope & programme
Target milestones, requested quotation alternatives, packing, transport and installation responsibilities to discuss.
Separate inputs, decisions and records
A preliminary inquiry can begin before all selections are complete. The useful output of each discussion is a clearer record of what is included, what is excluded and what is still open.
| Buyer input | Confirm together | Record to keep |
|---|---|---|
| Plans, elevations, schedule and revision | Opening IDs, quantities, dimension basis and missing details | A coordinated opening list and unresolved questions |
| Selected model and requested glass, finish or hardware | Applicable configuration, options and any supporting evidence | Configuration reference for each opening or group |
| Destination, site constraints and target milestones | Packing, transport, unloading and installation scope | Agreed quotation scope, exclusions and responsibilities |
| Reviewed drawings and quotation | Final dimensions, directions, specifications and commercial terms | The expressly agreed revision before an order is confirmed |
Connect the brief to real systems
Compare the existing window and aluminum door ranges by their listed configurations. Where a model has an interactive opening demonstration, use it to understand movement; the demonstration does not establish a project's final size, load or performance.
Confirm the boundary of the quotation
Do not assume that delivery includes import clearance, unloading or installation. Write the agreed boundary into the quotation and order documents, including the exact named destination where relevant.
Technical approval
Identify who checks final measurements, installation details, project requirements and the scope of any test report.
Packing & transport
Discuss package type, labels, loading and handling constraints, required documents and the agreed transport scope.
Arrival & installation
Agree who receives, unloads, stores and installs the goods and how quantity or damage discrepancies are recorded.
Changes
Tie changes to the relevant opening IDs and drawing revision; reconfirm any effect on configuration, quotation and programme.
Questions before requesting a project quotation
Can we start with preliminary drawings?
Yes, use the current inquiry form to explain the project and share available information. Label preliminary sizes and unresolved selections; an accurate quotation still needs an agreed scope.
Does a catalog configuration satisfy our local requirements?
That cannot be assumed. Provide the applicable requirements and required report or approval scope so the specific product configuration can be discussed.
Are installation or import services included?
Only expressly agreed services are included. Confirm technical, transport, customs, unloading and installation responsibilities separately.
Start with your requirements.
Share your project location, opening schedule and the requirements already known. Mark preliminary information so it can be separated from confirmed instructions.
