Which Chinese aluminum extrusion and window system manufacturers actually supply the volumes and certification levels commercial building projects require? Aluminum windows and doors for a hotel, office tower or apartment complex are a different sourcing problem than a single villa order — profile consistency across hundreds of units, thermal-break performance for the destination climate, and a factory that can hold tolerances at scale all matter more than showroom finish samples. This guide — from FBM Sourcing, your sourcing agent and sourcing partner in China — covers the established Chinese aluminum manufacturers most frequently supplying commercial window and door systems.
| Manufacturer | Headquarters | Known For |
|---|---|---|
| Xingfa Aluminium (兴发铝业) | Foshan, Guangdong | One of China’s largest aluminum extrusion producers, Hong Kong-listed |
| China Zhongwang (中国忠旺) | Liaoyang, Liaoning | One of the largest aluminum extrusion producers globally, Hong Kong-listed |
| Guanya Aluminium (广亚铝业) | Foshan, Guangdong | Established building-system aluminum profile manufacturer, Shenzhen-listed |
| JMA Aluminium (坚美铝材) | Foshan, Guangdong | Major aluminum window/curtain wall systems supplier to large real estate projects |
| Alnan Aluminium (亚铝集团) | Nanning, Guangxi | Large-scale aluminum extrusion producer |
Xingfa Aluminium (兴发铝业)
Headquartered in Foshan and listed on the Hong Kong Stock Exchange, Xingfa is one of China’s largest aluminum extrusion manufacturers, supplying profiles for windows, doors, curtain walls and industrial applications at national scale. Choose Xingfa when you need a large, publicly listed supplier with the extrusion capacity to hold a multi-hundred-unit window schedule on one production line.
China Zhongwang Holdings (中国忠旺)
Based in Liaoyang and listed on the Hong Kong Stock Exchange, China Zhongwang is one of the largest aluminum extrusion producers in the world, with both industrial and building-sector product lines. Choose Zhongwang for large industrial-grade extrusion orders where global production scale is the priority.
Guanya Aluminium (广亚铝业)
Guanya, headquartered in Foshan and listed on the Shenzhen Stock Exchange, is an established building-systems aluminum profile manufacturer with a longer track record specifically in architectural/construction aluminum rather than pure industrial extrusion. Choose Guanya when your project needs a manufacturer with dedicated building-systems engineering experience.
JMA Aluminium (坚美铝材)
JMA, based in Foshan, is a major supplier of aluminum window, door and curtain wall systems to large Chinese real estate developments — relevant reference experience for overseas developers running comparable multi-tower or multi-building projects. Choose JMA when your project’s scale and building-system complexity mirrors large domestic real estate developments.
Alnan Aluminium (亚铝集团)
Alnan, headquartered in Nanning, Guangxi, is a large-scale aluminum extrusion producer serving both industrial and construction sectors. Choose Alnan as an alternative large-capacity supplier when comparing quotes across multiple factories for a bulk window and door package.

Which Manufacturer Should You Shortlist for Which Project?
Rankings matter less than fit. Use this table to map your specification to the manufacturers above — then price two or three against each other rather than negotiating with one.
| If your project needs… | Shortlist first | Why |
|---|---|---|
| A custom profile system with engineering support on a mid- or high-rise | Xingfa Aluminium | Deep custom-extrusion capability with system engineering behind it |
| Very large extrusion volume on an industrial schedule | China Zhongwang | One of the largest extruders in Asia; volume is the core strength |
| Export project pricing on proven standard systems | Guanya Aluminium | Export-oriented production of established system profiles |
| A finish-critical facade — powder coat or anodising quality leads | JMA Aluminium | Finishing quality reputation across powder and anodised lines |
| Extrusion plus fabrication capacity in one supplier | Alnan Aluminium | Integrated extrusion-to-fabrication capability |
Evidence to Request Before You Shortlist
Catalogues and showrooms all look convincing. What separates a window and door manufacturer that will perform on a commercial project is the documentation it can produce for your specification — request these items with your RFQ, and treat slow or partial answers as information:
- System test reports for the actual window system and glass build-up you are specifying — AS 2047 + WERS data for Australia, NFRC for the US, EN 14351 for Europe — not a different system from the same catalogue
- Mill certificates for alloy and temper of the profiles quoted
- Powder-coat or anodising specification in writing: coating class, film thickness and finish warranty term
- Sample corner joints from production showing fabrication tolerances and drainage detail
- Project references at comparable wind-load and height, with delivered m²
- Written lead time for your m² including tooling, extrusion, finishing and glazing stages
On FBM-managed packages our own QC team collects and cross-checks every one of these documents against the actual production batch during factory visits and inspection before shipment — so the evidence file your project holds matches the goods in the container, not just the brochure.
How to Buy aluminum windows and doors at Project Pricing
- Go through project/engineering channels, not retail. The manufacturers above sell to distributors and B2C showrooms at very different pricing and lead times than their project sales channels. A sourcing agent with existing factory relationships accesses project pricing directly.
- Match certification to your destination market. Export-configuration products differ by country; confirm the exact certificate matches the model you are ordering, not just the manufacturer’s general compliance claims.
- Inspect before the container is sealed. Pre-shipment inspection catches finish defects, dimensional drift and packaging issues before they become an installation problem on your site.
- Consolidate across categories. If your project also needs other building materials or FF&E, ordering through one coordinated sourcing plan reduces the number of shipments and QC touchpoints.
