Trellis Doors

What is the Expandor?

During the day these trellis doors and windows are virtually invisible, folding behind curtains and blinds, or to the side of the opening.  At night they close to provide formidable strength and maximum ventilation.  The expanding trellis doors are also very popular in securing shopfronts and commercial premises, acting as a deterrent to ram-raids, break-ins, and vandalism.  During the day the doors tuck out of the way to ensure an unobstructed view of merchandise.  At night they provide maximum through-vision enhancing store presentation.

It has a super secure slam-lock for quick protection and is easily operated under all conditions.  The product is galvanised and epoxy-coated for corrosion protection

Why should I choose the Expandor for my home or Business?

The Expandor is a strong expanding trellis door with steel verticals fully supported by the surrounding tracking mechanism. Each vertical section comprises two vertically opposed square steel tubes in each upright. The steel cross linkages span across three vertical uprights forming a strong formidable security barrier.  The Expandor has been treated, epoxy powder-coated and galvanised against corrosion to make it a long lasting security product.

The Expandor does not require a key to lock.  It takes only seconds to close and lock making it perfect for protection in open areas such as homes, units, banks, shop fronts, hotel bars, closed warehouse areas etc. After stringent burglar resistant static load testing, the Slam-lock proved to be unquestionably stronger than other locking systems. It utilises 12mm pins for extra strength, has three locking points in the lock style, including a double hook for extra strength

During the day the door folds away out of site to approximately 15-20% of its opening size, making it very unobtrusive.  At night they close to provide formidable strength and maximum ventilation. 

This trellis door is custom made with measurement and fitting being carried out by our design team.
