OMD’s aluminium concertina doors (folding doors) offer a modern alternative to traditional sliding or hinged doors, with panels that fold in a zigzag pattern for compact storage. The aluminium frames are reinforced for stability, while the concertina mechanism ensures smooth operation even in high-traffic areas. These doors can be fitted with Low-E glass for energy efficiency or frosted glass for privacy, making them suitable for office partitions or residential living spaces. Customization includes color-matched hardware and integration with building automation systems.
