Commercial Door Automation

At 3MC, our automatic sliding doors have been built using interchangeable construction principles. This allows the system to be transformed safely and efficiently. This results in benefits for the customer of shorter installation times and reduced service and maintenance costs.

Single or double leaf automatic sliding doors are exceptionally versatile.

  • Opening widths of 800 mm to 3 000 mm.
  • Can accommodate door weights of up to 1 x 200Kg or 2 x 150 Kg.

Automating swing doors are a relatively simple, yet highly sustainable way to enhance the performance, accessibility and capacity of an entrance or exit point. 

  • Take up minimal space and maximise opening width.
  • Can be used as the basis for a wide variety of swing door applications thanks to its advanced programmable micro processor and compact design.
  • It is almost silent in operation which makes it additionally suitable in quieter environments.

The versatility of this automatic door operator means it can also be used as a control system to provide fire and smoke protection and it is a system which can be extended with a master-slave function which facilitates two overlapping door leaves.

Telescopic sliding doors are linear models with more than one door leaf per side. The inner door is connected to the outer via deflection rollers, and slides at twice the speed. This enables rapid opening in very wide passages.

Bespoke Sizes and Finishes are also avaiable upon request.
