From supplier search to technical decision
Choose a China aluminum door factory by what arrives on site—not by catalogue appearance alone
For developers, contractors, distributors and design teams, sourcing aluminum doors from China involves more than selecting a visual style. A door package must coordinate opening dimensions, panel movement, frame depth, glass weight, threshold, drainage, locking, surface finish, wall interfaces and international handling.
DER Building uses drawings, door schedules and project requirements to organize these decisions before material is processed. This specification-first workflow helps buyers compare quotations on the same basis and reduces avoidable changes after production begins.
✓
Clear quotation basis: door type, configuration, included components and assumptions can be recorded for review.
✓
Project-oriented customization: sizes, colors, glass, hardware and packing are discussed around the actual application.
✓
Responsible performance language: test reports, certificate scope and technical values should be matched to the offered series and configuration.
A complete door specification connects the frame, glass, seals, hardware, threshold and installation interface.
Aluminum door product range
Match the opening method to space, traffic and weather exposure
The right system depends on how the opening is used, how much clear access is required, where panels can move, the expected glass weight and the level of environmental control needed.
Aluminum Hinged Doors
Single- or double-leaf arrangements for entrances, service rooms, offices and commercial access. Hinge capacity, lock function, closer, threshold and opening direction require early coordination.
Aluminum Bi-Fold Doors
Multiple panels fold and stack to create a broad opening. Panel count, stacking side, traffic leaf, track support, floor transition and hardware load should be defined in the drawing stage.
Folding Door Configurations
Suitable where flexible division and a generous opening are priorities. The system can be reviewed for villas, restaurants, showrooms and interior–exterior transitions.
Thermal-Break Aluminum Doors
For conditioned interiors, the insulated profile, glass make-up, spacer, gaskets, threshold and perimeter sealing should work as one system. Final values depend on the selected configuration.
Commercial & Hospitality Door Packages
Retail, hotel, restaurant and office projects may require higher traffic hardware, controlled access, coordinated finishes, package labels and a clear replacement-parts plan.
Four decisions that shape the door
Start with use conditions, then select the aluminum door system
A product name alone does not determine suitability. These four questions establish a practical starting point for system selection.
01 · MOVEMENT
How should the door open?
Sliding conserves floor space; hinged gives direct access; folding creates a larger clear opening.
02 · ENVIRONMENT
What must it resist?
Review wind exposure, rainfall, temperature difference, noise, salt air and interior humidity.
03 · OPERATION
Who will use it?
Traffic frequency, panel weight, accessible transitions, locking and maintenance affect hardware choice.
04 · DELIVERY
How will it reach the opening?
Package size, lifting route, assembled or knock-down condition and glass handling influence production planning.
Aluminum door specification table
Items to confirm before production release
| Specification area | Project choices to discuss | Procurement impact |
|---|---|---|
| Door type | Sliding, hinged, folding or bi-fold; single or multiple panels; fixed sidelights where required. | Controls opening space, panel movement, frame layout, hardware and site clearance. |
| Aluminum system | Frame series, depth, sash design, thermal-break or non-thermal-break construction, visible sightline. | Influences strength, insulation, appearance, glass capacity and wall interface. |
| Dimensions | Overall frame size, panel divisions, mullions, handing, stacking position and allowable tolerances. | Determines manufacturability, operation, package size and coordination with structural openings. |
| Glass | Tempered, laminated, insulated, Low-E, tinted or acoustic build-ups, subject to project requirements. | Affects safety, thermal behavior, sound control, daylight, weight and hardware capacity. |
| Surface finish | Powder coating, anodized appearance or wood-grain finish; color code, texture and gloss reference. | Supports façade coordination, appearance consistency and approval control. |
| Hardware | Rollers, hinges, handles, locks, multi-point locking, closers, stops and access-control interfaces. | Determines load capacity, security, operating effort, serviceability and user experience. |
| Sealing & drainage | Gaskets, brush seals, corner treatment, drainage paths, sill and perimeter sealant interface. | Contributes to air and water control when matched with the correct installation method. |
| Threshold | Standard, raised, recessed or project-specific transition within the selected system limits. | Affects drainage, weather resistance, finished floor coordination and accessibility. |
| Accessories | Screens, trims, subframes, flashings, anchors, connectors, spare parts and installation items. | Clarifies the boundary between factory supply and site work, reducing missing-item risk. |
| Packing | Assembled or knock-down condition, protective film, foam, crates, glass protection and labels. | Supports international handling, opening identification, unloading and installation sequencing. |
Custom aluminum door manufacturing workflow
A controlled path from inquiry to export shipment
Complex projects move faster when technical and commercial decisions follow a defined approval sequence.
Requirement Review
Drawings, opening list, quantities, project location, intended use, performance needs and delivery requirements are collected.
System Proposal
Opening type, frame series, glass, finish, hardware, threshold and package approach are proposed for discussion.
Quotation Clarification
Included components, assumptions, exclusions and commercial terms are organized so the scope can be compared accurately.
Drawing & Sample Approval
Door elevations, details, handing, color references, glass and hardware samples are approved as required.
Production & Inspection
Profiles, glass and components are processed, assembled and checked according to the confirmed order.
Packing & Dispatch
Protection, labels, accessories, quantities and shipping documents are reviewed before shipment release.
Quality control for aluminum doors
Inspection should follow the door through each manufacturing stage
A finished frame can hide dimensional, sealing or hardware issues. Staged checks help identify deviations before doors are packed for international delivery.
1
Material verification
Check profile series, finish reference, glass make-up, gaskets and specified hardware against approved documents.
2
Profile processing
Review cutting, machining, drainage openings, lock preparation and component positions before assembly.
3
Frame geometry
Confirm width, height, diagonals, joint condition, panel alignment and visible workmanship.
4
Glazing & seals
Check glass orientation, setting support, gasket continuity, edge protection and seal condition.
5
Operation test
Open, close, lock and adjust the door; verify rollers, hinges, handles, stops and clearances.
6
Export package check
Confirm protective materials, package labels, accessory cartons, quantities and loading information.
For regulated or performance-sensitive projects, request documents that identify the applicable product series, configuration, size range and test scope. General company credentials should not be assumed to cover every possible door option.

China aluminum door sourcing guide
Compare quotations line by line before comparing the total price
Two suppliers may use the same product description while offering different profile systems, glass, hardware, thresholds, accessories and packing. These checks help expose differences before a purchase decision.
1. Ask for the exact frame series
Review section drawings, frame depth, sash design, thermal-break construction and proposed panel size—not only a rendered image.
2. Confirm glass and hardware as named items
Glass build-up and hardware capacity affect safety, performance, panel weight, operation, replacement and cost.
3. Review the threshold and drainage detail
The sill transition must coordinate with floor levels, weather exposure, support, waterproofing and installation access.
4. Match documents to the offered configuration
Check whether tests or certificates relate to the exact series, opening type, glass, size range and target market.
5. Define packing and labeling in the order
Record whether units ship assembled, how glass is protected, how packages are labeled and where accessories are packed.
