The hangar door and side-folding doors are opened by vertical wings climbing each other with hinges and folding the wings sideways.
All system details used in folding doors comply with EU standards and norms. These doors, which are used as hangar doors, are among the most preferred door models.


The AT model is a door where the vertical wings are hinged one another, and whose folding system complies with the EU rules & regulations. Its features are as follows:

Structure of panels :

Pre-painted zinc sheet, 8/10 thick, both on inside and outside; inner frame: metal sheet section bar, hot dip zinc galvanised, 15/10 thick; inner filling: B2 self-extinguishing class, CFC-free foamed polyurethane (density 40-45 Kg/cubic metre).

Standard outside colours :

Similar to RAL 9002, RAL 5010, RAL 8019, RAL 6005, RAL 3003, and RAL 9006

Inside colour :

Standard is similar to RAL 9002. Like outside colour if requested

Side pillars :

Hot dip zinc galvanised metal sheet, 15/10 thick.

Sliding guide :

Press-formed hot dip zinc galvanised metal sheet, 30/10 thick.

Rotation hinges for wings :

Zinc plated and painted metal sheet, with a 20 mm diameter hinge pin and axial ball bearings, with zinc plated and black powder-painted solid balls. They are burglar resistant, as fastening screws are inaccessible when door is closed.

The AT model design is functional, strong and essential, like an industrial product must be.
The outside metal sheet, 8/10 thick, and the large hinges ensure great resistance to all the stress that an industrial door unavoidably undergoes year by year.
With their overhead sliding guides and their 180° wings pack rotation, both exclusively patented, Arco Industrie has reached an unparalleled standard of simplicity, reliability, tradition synthesis, experience and constant research.
