Expandoor is the only high security trellis door manufactured in New Zealand for our conditions. The trellis doors lattice is constructed from steel and powder coated to any colour of your choice. This security door is fully framed and hangs on top rollers for an easy glide with a bottom track guide. This protects the door opening in a curtain of steel. The use of high quality bearings on the head gear makes the opening and closing of this heavy duty grille a breeze. The bottom track can be removed during trading hours to provide unhindered access to the entrance way. Each trellis door is manufactured in our Auckland factory and tailored to individual client requirement. The locking system can be keyed alike to existing systems. The Expandoor stacks to 15% of its locked size requiring reduced stacking space.
