One line, from bar stock to finished window.
A window factory, not a trading office.
Profile machining, insulating glass and final assembly happen under one roof — a drawing change does not travel between three suppliers.
BOLTON systems are engineered and assembled by GILXAN (Guangdong Jili Huangxuan Door & Window Technology Co., Ltd.) at a single manufacturing base in Guangdong. Cutting, machining, thermal-break assembly, insulating glass and final window assembly all take place in the same building.
That matters most on project orders: one technical contact owns the drawing, the sample, the production batch and the container loading. There is one place for a question to go.
We publish what can be verified. Plant area, headcount and the full machine list are released in the factory audit pack rather than presented as headline numbers on a website.
If you need to check capacity or a process, we can arrange a video walk-through of the stations relevant to your order, machine by machine and check by check.
In-house insulating glass
Glass is cut, washed, filled, sealed and pressed on site, so the glazing build-up matches the approved sample.
Machining under one roof
Cutting, drilling, milling and thermal-break assembly finish before the frame reaches the assembly bench, so dimensional issues surface at the source.
Sample before batch
A corner or full-leaf sample is approved before a production run; colour, hardware and feel follow the signed sample.
Export packing
Film, corner guards, crates and vertical glass loading are specified per order and checked against the packing list before loading.
Every joint starts at a machine.
Twelve working stations from the current line, photographed on site. No stock imagery.
Equipment images are taken on site. Model designations, acceptance records and maintenance logs are available during a factory audit.

From profile intake to container loading, each stage carries its own check — not one inspection at the end.
Materials, stated plainly.
Material categories used in the systems. Supplier names are disclosed for project evaluation on request.
These are selected materials. Listing does not imply brand authorisation, partnership or endorsement.
