First, choose the appropriate aluminum profile.

Aluminum alloy window and door profiles can be made of different materials and specifications according to specific needs.

Secondly, carry out profile processing.

Aluminum alloy profiles can be processed by cutting, punching, milling, etc. to meet the design requirements of windows and doors.

Then, connect the profiles.

Common connection methods include threaded connection, corner key connection by crimping machine, hinge connection, etc.

These connections ensure the stability and sealing of doors and windows.

Finally, surface preparation and assembly are performed.

The surface of aluminum alloy doors and windows can be treated with anodizing, electrophoretic coating, etc. to improve its corrosion resistance and aesthetics.
