Windows and Doors Wholesaler in China: Door Window Accessories, Soundproof Specs & Pricing
Windows and Doors Package Pricing from a China Wholesaler
Package pricing is quoted per square meter of clear opening for windows and per unit or per square meter for doors, all on the same commercial invoice. The bands below are FOB Foshan/Guangzhou for thermal break aluminum frames with double glazing (5+12A+5 tempered), powder coating and standard hardware.
FOB Price Bands by Product Line
| Product line | FOB band | Typical config | Price driver |
|---|---|---|---|
| Casement window | $48-72 / m2 | 60 series, 24 mm PA66 strip, 5+12A+5 | Glass build, opening sashes per m2 |
| Sliding window | $42-60 / m2 | 80/90 series, twin track, rollers | Track count, screen option |
| Awning window | $50-70 / m2 | 60 series, chain winder or friction stay | Hardware grade |
| Entrance door | $180-320 / unit | 900×2100 mm, multi-point lock | Panel fill, lock brand |
| Sliding patio door | $95-140 / m2 | 100/120 series, 2-4 panels | Roller load class, lift-and-slide option |
| Folding door | $120-190 / m2 | 75/80 series, 3-7 panels | Panel count, top-hung vs bottom-rolling |
Bands assume 300-800 m2 mixed orders; smaller lots add 8-12%.
Volume Discount Tiers on Mixed Orders
| Order volume (windows + doors) | Discount vs list | Extra terms |
|---|---|---|
| 100-300 m2 | list price | Standard 30/70 T/T |
| 300-800 m2 | -6% | Free 2% spare hardware |
| 800-1500 m2 | -11% | Free shop drawings + PVDF upgrade at cost |
| 1500 m2 and up | -16% | Dedicated QC inspector, weekly production report |
What Actually Moves the Price
- Triple glazing (5+12A+5+12A+5) adds $18-26 / m2 and roughly 10 kg per m2 of frame load.
- Laminated acoustic glass (6+1.14PVB+6) adds $22-34 / m2 over standard double glazing.
- PVDF coating instead of polyester powder adds $6-9 / m2 but extends salt-spray rating from 1000 to 3000 hours.
- Widening the thermal strip from 24 mm to 34 mm adds about $7 / m2 and cuts Uw by 0.3-0.4 W/(m2-K).
Doors and Windows on One Extrusion Platform
Every product line in the package runs on the same 6063 aluminum billets, the same PA66GF25 thermal strips and the same 14 mm Euro-groove hardware channel. One platform means one set of shop drawings, one gasket profile and one spare-parts shelf for the whole house.
6063-T5 vs 6063-T6 Mechanical Data
| Property | 6063-T5 | 6063-T6 |
|---|---|---|
| Tensile strength | >=160 MPa | >=205 MPa |
| Yield strength | >=110 MPa | >=180 MPa |
| Elongation | >=8% | >=8% |
| Typical use | Standard windows, interior doors | Wide-span doors, high-wind zones, oversized sashes |
| FOB impact | base | +$3-5 / m2 |
Thermal Break Strips and Series Selection
| Series | Strip width | Frame depth | Uw with 5+12A+5 | Wind rating |
|---|---|---|---|---|
| 55 | 20 mm | 55 mm | 2.4 W/(m2-K) | Class 6 / 2.5 kPa |
| 60/65 | 24 mm | 60-65 mm | 2.0 W/(m2-K) | Class 7 / 3.0 kPa |
| 70 | 24-28 mm | 70 mm | 1.8 W/(m2-K) | Class 8 / 4.0 kPa |
| 80 | 34 mm | 80 mm | 1.4-1.5 W/(m2-K) | Class 9 / 5.0 kPa |
Surface Finishing Lines
- Polyester powder coating, 60-80 um film, AAMA 2603, 1000 h neutral salt spray.
- PVDF fluorocarbon, >=30 um film, AAMA 2605, 3000 h salt spray – specify for coastal projects.
- Anodizing 15-20 um in silver, champagne or bronze for scratch-prone commercial entrances.
- Wood-grain sublimation over powder base for villa projects that need timber aesthetics with aluminum maintenance.

Guangdong Aluminum Alloy Doors and Windows Supply Chain
Guangdong aluminum alloy doors and windows benefit from the densest fenestration supply chain in China: extrusion presses, thermal strip lines, glass processors and hardware die-casters all sit within a 60 km radius of the fabrication plant in Foshan. Short supply legs are why mixed windows-and-doors packages hold 25-35 day lead times.
60 km Supply Radius Map
| Input | Cluster location | Distance | Lead leg |
|---|---|---|---|
| 6063 billets + extrusion | Nanhai / Dali, Foshan | 8-15 km | 7 days per die run |
| PA66GF25 thermal strips | Shunde, Foshan | 20 km | 2-3 days |
| Float + tempered glass | Dongguan / Zhongshan | 40-60 km | 5-7 days |
| Hardware die-casting | Jinli, Zhaoqing | 50 km | 4-6 days |
| Powder coating line | in-house / Foshan | 0-10 km | 3 days |
Lead Time Breakdown for a Mixed Package
- Days 1-7: extrusion of package profiles (windows and doors share the run).
- Days 8-10: powder coating or PVDF; glass cutting and tempering in parallel.
- Days 11-24: cutting, machining, assembly, glazing of all lines.
- Days 25-27: 100% QC + water spray test; packaging and container booking.
- Total: 25-35 days FOB for a 300-800 m2 mixed order.
QC and Pre-Shipment Inspection
Every unit passes dimensional check (+/-1.0 mm), operation torque test and a 10-minute water spray at 300 Pa before crating. Third-party inspection (SGS/TUV/BV) is accepted at buyer cost, typically $180-260 per man-day, and most wholesalers book it on the first order of a new series.
Soundproof Doors and Windows Packages
Soundproof doors and windows are specified as a glass-and-sealing package, not a separate frame series. The same 70/80 thermal break frames accept acoustic glass builds; the difference is lamination, cavity asymmetry and perimeter sealing.
Rw / STC by Glass Configuration
| Glass build | Rw (lab) | Field STC after install | FOB adder vs 5+12A+5 |
|---|---|---|---|
| 5+12A+5 double | 30-31 dB | 28-29 | base |
| 5+12A+5+12A+5 triple | 36-38 dB | 34-35 | +$18-26 / m2 |
| 6+1.14PVB+6 + 12A + 5 laminated | 40-42 dB | 37-39 | +$22-34 / m2 |
| 6+1.14PVB+6 + 16A + 8 asymmetric | 43-45 dB | 40-42 | +$30-42 / m2 |
Lab values per ASTM E90 / ISO 10140 on 70 series casement, 1.5 x 1.5 m test specimen.
Sealing and Installation Impact
- Three-layer EPDM perimeter gaskets with welded corners hold compression for 10+ years.
- A 5 mm unsealed install gap costs 3-5 dB of field STC – specify expanding foam plus backer rod plus acoustic sealant.
- Sound-rated doors need drop-down bottom seals; add $9-14 per door leaf.
- Pair acoustic windows with solid-core entrance doors (>=42 kg/m2) or the door becomes the weak path.

Even after a 5% contingency for breakage and re-supply, the package route saved NZ$580,000+ and removed two supplier interfaces from the program. Related door-side pricing: entrance door manufacturer price tables and french doors manufacturer specs.
Package vs Split Sourcing: When Each Route Wins
Side-by-Side Comparison
| Factor | Single package (one wholesaler) | Split sourcing (2-3 factories) |
|---|---|---|
| Lead time | 25-35 days, one clock | 30-45 days, slowest factory rules |
| Frame color match | Same powder batch, delta-E <1 | Two batches, visible mismatch risk |
| Container use | 92-96% cube fill | 70-85% fill, two partial loads |
| QC interface | One inspection, one report | 2-3 inspections, duplicated cost |
| Hardware compatibility | One groove standard | Risk of mixed groove systems |
| Price leverage | -6% to -16% volume tiers | List price on small splits |
When to Split Anyway
- Projects over 5,000 m2 where two plants de-risk a force-majeure stop.
- Specialty lines outside the platform (curtain wall unitized systems, fire-rated steel doors).
- A local code requires a hardware brand the package factory does not stock – buy hardware separately and confirm groove compatibility first.
