How to Request a Quote for Custom Commercial Doors from China
Define the quotation scope
A useful custom commercial door quotation begins with a clear package boundary. State whether the supplier should include door leaves, frames, glazing, louvers, seals, hardware, labels, spare parts and export packing. Identify any items that will be sourced locally so responsibilities are not duplicated or omitted.
Send a structured door schedule
List the door mark, quantity, size, handing, leaf material, frame, finish, rating, vision panel and hardware set for each opening. If some details are provisional, label them as allowances. The commercial door schedule guide explains the fields that make supplier comparisons more accurate.
Attach drawings and specifications
Plans, elevations, wall sections and specification pages help suppliers understand opening locations and interfaces. Mark the latest revision and identify conflicts between drawings and schedules. Provide the destination country and any project standards, evidence or document formats that must be reviewed.
Coordinate hardware and access control
- Provide hardware sets or preferred functions by door mark.
- Confirm whether hardware is installed, supplied loose or excluded.
- Show electrical preparation for locks, contacts and power transfer.
- Identify panic hardware, closers and special reinforcement.
Use the door hardware preparation guide to organize machining and reinforcement information before production.
Include commercial and delivery details
State the required currency, trade terms, delivery location, target schedule and preferred packing sequence. Ask the supplier to separate optional items, tooling or sample costs. For repeated openings, request package labels that cross-reference the approved door marks.
Compare assumptions before selecting a supplier
Review whether quotations cover the same configuration, documents and accessories. Clarify exclusions, lead times, drawing approval milestones, replacement-part handling and payment stages. The lowest total may not include equivalent scope.
Submit a complete inquiry package
Combine the schedule, drawings, specifications, hardware, finish references and delivery information into one controlled file set. Use the project quotation form to upload the package and request a door-by-door response.
