Aluminum alloy folding doors are classified into the following types according to different methods:

By style: mainly divided into side-mounted folding doors and push-pull folding doors. Side-mounted folding doors move along the upper guide rail through the guide wheel on the upper part of the door leaf to achieve the folding and opening of the door leaf; push-pull folding doors are pushed and folded through the pulley or track at the bottom.

By the ease of installation: can be divided into simple folding doors and complex folding doors. The hinges for connecting the folding door leaf of simple folding doors are relatively special; the upper and lower tracks of complex folding doors use rotating hardware accessories.

By usage: there are manual folding doors, electric (traditional) folding doors, and electric (dual-machine) folding doors. Manual folding doors require manual operation of the switch; electric (traditional) folding doors achieve automatic opening and closing through motors, racks and other devices; electric (dual-machine) folding doors rely on two sets of crank-type door opening mechanisms to complete the opening and closing actions.

By regional characteristics: there are southern and northern differences. The northern styles are more stable, often with elements such as lattice and aluminum flowers, among which the most distinctive one is Tang grid; the southern styles are relatively lively and diverse.
