For panic opening in automatic sliding doors, a special stile has been developed to hinge outwards for emergency exit.









The Commercial door can accommodate glazing panels between 6mm and 24mm.

The commercial doors can either be a pivot door or a sliding door.  Sliding doors are ideal for car showrooms, airports and shopping complexes. We understand how important the reliability of the doors are.  Many of the installations shown on the website were installed over 20 years ago when CMC Aluminium was first started!

In the event of an emergency, the system can be opened up in a safe, trouble-free way.

If an incident arises, the sliding doors (which are fitted with hinges)  can be opened manually with the same swivel action as a normal door to provide an escape exit and access route for the emergency services. Especially helpful in the event of panic. They have practical full-width opening system.  Push open the raised sliding leaves and side panels to create a wide, practical opening for transport access or for use in summer. Bulky objects, or even vehicles, can then be moved from one area to another without difficulty.   In day-to-day operation, the automatic drive system opens and closes reliably to ensure unhindered, contact-free access.
