Window & Door Customization
Last reviewed: September 2026
You don’t need to adapt your project to a catalog. Send us your window and door schedule, your drawings, or simply a photo of the look you want—and we match the design, engineer it, produce it, certify the documentation for your market, and load it into a container. Custom-made orders are dispatched within 30 days; standard-configuration products ship within one week of confirming materials, style, and price. That is what sourcing custom windows and doors from China looks like when the whole supply chain sits in one place.
The offer in one paragraph: any size, any RAL color (dual-color inside/out included), any glass from tinted to stained, any opening type—manufactured to your specification, matched to your destination’s certification requirements, at the cost structure of the world’s largest building-materials supply chain. Custom production to dispatch: ≤ 30 days. Finished products: ≤ 1 week.
Why China Can Do This: The Numbers Behind the Promise
Speed and price are not slogans; they come from industrial concentration. China produces roughly 60% of the world’s primary aluminum—the raw material of modern window and door systems—and accounts for about 28% of global manufacturing value added, the largest share of any country. For a window and door buyer, this concentration means every input of your order—profiles, glass, hardware, coatings, gaskets—sits within one supply radius instead of three continents.
| Indicator | Figure | What it means for your order | Source |
|---|---|---|---|
| China primary aluminum output, 2024 (est.) | ~43 million tonnes of ~72 million world total (~60%) | Profile systems of every series and finish are produced domestically at scale—no imported-material lead time | USGS Mineral Commodity Summaries 2025 |
| China share of global manufacturing value added, 2024 | ~$4.65 trillion of ~$16.6 trillion (~28%) | The deepest subcontracting ecosystem in the world: glass plants, hardware makers and coating lines clustered together | World Bank national accounts data |

Your Requirements, Matched: What We Customize
Tell us what the project needs in any format—a window schedule, architectural drawings, a specification document, or reference photos. We translate it into a manufacturable design and quote it line by line. These are the axes we match:
| Your requirement | How we match it |
|---|---|
| Non-standard sizes, oversized entries, shaped openings | Made-to-measure production to your schedule; oversized pivot and sliding entries; arched, round and angled windows; oversized units engineered against the system’s tested limits |
| A specific look or a photo to replicate | Design matching from reference images—profile proportions, divided-lite patterns, colors and hardware style reproduced and quoted |
| Exact colors, inside and out | RAL color matching on powder coat, PVDF, anodized or wood-grain finishes; dual-color (dark outside, white or timber-look inside) on aluminum and uPVC systems; physical samples for approval |
| Performance targets for your market | Thermal-break profiles, double or triple glazing, Low-E, argon, laminated and tempered build-ups specified to hit your U-factor, SHGC and wind-load requirements |
| Decorative and privacy glass | Tints, frosted, reflective; true divided lites, simulated divided lites and grilles-between-glass; stained and leaded panels; integral blinds between the panes |
| Door systems for every opening | Swing, sliding, bifold, French and pocket doors in engineered wood, WPC, steel, and aluminum-and-glass—see our door product range and window systems |
| Hardware to your tier | From proven domestic sets to international brands, named in the quote; corrosion-class options for coastal projects |
China Speed: From Your Requirement to a Loaded Container
Two commitments define our timeline. Finished, standard-configuration products—once materials, style, and price are confirmed—are dispatched within one week. Fully custom orders move from confirmed drawings and samples through production to container dispatch within 30 days.
This pace is only possible because of the supply chain described above: profile extrusion, glass processing, hardware, and coating are all sourced within the same manufacturing cluster, so nothing waits on an overseas supplier. Your order moves through five steps, each with a clear output:
| Step | What happens | What you receive |
|---|---|---|
| 1. Send your requirement | Schedule, drawings, or photos—any format | — |
| 2. Design matching & quotation | We match systems, glass, colors, and hardware to your design and budget | Line-item quotation with every option priced |
| 3. Drawing & sample confirmation | CAD shop drawings per unit type; physical color, finish, and glass samples | Drawings and samples for your written approval—the production master |
| 4. Production | Fabrication to the approved drawings, with milestone updates | Progress photos on request |
| 5. Pre-shipment check & dispatch | Quantity, labeling, finish, and operation checked; export packing; container loading | Inspection and loading photos; your container on the water—≤ 30 days for custom orders |
Working to a project deadline? Send us your schedule and target date—we will confirm the production slot and quote within days.
China Price: Where the Value Actually Comes From
Buyers who compare like for like—same profile system, same glass build-up, same hardware tier, certified to the same destination standard—consistently find that sourcing from China lands at a significantly lower total cost than procuring the same specification locally in the US, Europe, or Australia. The gap is structural, not a discount:
- Inputs are local and at scale. When 60% of the world’s aluminum and the world’s largest glass industry are domestic, material surcharges and import markups disappear from the cost chain.
- Everything is made to order anyway. Local suppliers route most non-standard sizes to custom shops at custom-shop prices; in China, made-to-measure is the default production mode, so customization carries a far smaller premium.
- One shipment, one supplier group. Windows and doors consolidated with cabinets, tiles, sanitary ware, and other materials in a single container spread freight and eliminate multi-supplier coordination costs.
What this means for minimums: small orders are welcome when the palette and systems are consolidated—limit the colors and profile systems in one order, and minimums are rarely an obstacle. Sample units sit outside minimum-order logic entirely, so you can validate quality before committing. For the full cost picture—price structure, duties, and how to compare a China quote against a domestic one—see our 2026 windows and doors price breakdown.
Export-Grade Quality, Certified for Your Market
Price and speed mean nothing if the product fails inspection—yours or your market’s. Our windows and doors are produced for export from the start, and our certification portfolio covers every major destination market: CE and RoHS for Europe, ETL and UL for North America, SAA for Australia, TÜV-CB under the international CB Scheme, 3C for safety glass, and ISO quality management across production. For each order, we identify the standard framework your market requires and provide the certification documentation matched to your destination—not a generic certificate waved at every quote.
| Destination | Framework your project will ask for | What we provide |
|---|---|---|
| United States / Canada | NFRC-rated performance; NAFS (AAMA/WDMA/CSA 101/I.S.2/A440); safety glazing CPSC 16 CFR 1201 / ANSI Z97.1 | ETL and UL certified; configuration-matched test documentation; verifiable listings such as the NFRC Certified Products Directory where applicable |
| European Union / UK | CE/UKCA marking under EN 14351-1 | CE and RoHS certified; Declarations of Performance for the quoted configuration |
| Australia / New Zealand | AS 2047, referenced by the NCC | SAA certified; test evidence matched to the quoted system and configuration |
Quality is also controlled physically, not just on paper. Color, finish, and glass samples are approved before production; a full-size sample unit can be produced first for large or first-time orders; and every order passes a pre-shipment check with photo documentation before the container is sealed. Your approved samples stay on your side as the objective acceptance reference at delivery.
From Our Factory Floor to Your Site: A Custom Order in Pictures
The workflow above is what a real export order looks like. In the factory, frames are assembled to the approved drawings—like this dual-color unit, white on the interior face and dark on the exterior, being fitted out by our assembly team. Dual-color is one of the most requested customizations: the inner and outer profiles are finished separately, so a project can keep a dark, uniform facade and a bright interior in the same product.
Finished units are checked, labeled against the schedule, packed for export, and loaded—as the container photo in the speed section shows. And this is where the process ends: our dark-framed glazed door installed on a residential project overseas, delivered to the same drawings and finish that were approved weeks earlier at the factory.
Want your project to be the next case? Send your drawings or reference photos—we will match the design and quote it line by line.
Why George Group: A Chinese Supplier, a Tier Above
China has thousands of window and door factories. What separates a project-grade supplier from the rest is scale, consistency, and experience—and that is where George Group stands among Chinese suppliers:
Scale is what makes our promises hold. A 100,000 m² factory base and a 2,000-strong team mean your order is not queuing behind someone else’s: production slots, engineering capacity for shop drawings, and quality-control staff for pre-shipment checks are all in-house. Two decades of serving clients across North America, Europe, Australia, the Middle East, and Southeast Asia mean we already speak your market’s language—specifications, certification paperwork, packing standards, and the documentation your customs and your certifier expect.
And because George Group supplies the full package—windows and doors alongside kitchen cabinets, wardrobes, tiles, marble, sanitary ware, flooring, and lighting—your entire material schedule can come from one supplier, with one quality standard, one point of contact, and one consolidated container.
Talk to us about your project. Send your drawings, your schedule, or a photo of the look you want, and our team will come back with a matched design, a line-item quotation, and a production slot.
Frequently Asked Questions
How fast can you really ship custom windows and doors?
Fully custom orders move from your approval of drawings and samples to container dispatch within 30 days. Standard-configuration products dispatch within one week once materials, style, and price are confirmed. Sea freight time to your port is additional and depends on the destination—ask us for the current sailing estimate with your quotation.
Can I order custom windows and doors in small quantities?
Yes—customization itself doesn’t create the minimum; scattered specifications do. Keep one order to a tight palette of colors and profile systems and small orders are straightforward. A full-size sample unit is always available before the main order so you can validate quality first.
How much cheaper is sourcing from China, really?
Compared like for like—same system, glass, hardware, and certification—the China quote is typically significantly lower than local procurement in the US, Europe, or Australia, because materials, fabrication, and finishing all sit inside one supply chain. The honest comparison is always on identical specifications; our price breakdown shows how to build it, including duties and freight.
Will the products meet my country’s certification requirements?
We produce to export standards and hold CE, RoHS, ETL, UL, SAA, TÜV-CB, 3C, and ISO certification, with market-specific documentation matched to your destination and to the configuration you order. Your local architect, engineer, or certifier defines what your project must meet—we match the specification and provide the paperwork for it.
What should I send to get a quotation?
Whatever you have: a window and door schedule, architectural drawings, a specification, or photos of the look you want. We come back with a matched design and a line-item quotation, then CAD drawings and physical samples for your approval before anything enters production.
