The Hormann FST MZ is a sturdy, double skinned, sliding steel door which can be specified for multiple uses in many environments, commercial or industrial.
It is available as a single and double leaf system and also as a telescopic slidng door - 2 or 3 part.
It can also be specified to be used for smoke protection and is available in stainless steel too.

Hormann sliding doors offer a modern door appearance through a patented V groove at the element joint without visible screw connections. The high stability is ensured through the interlocked, toothed labyrinth plug-in profile. The elements are 72 mm wide, fully glued and flush, and aligned with each other through threaded rods. This creates a high-quality door leaf with parallel, uniformly wide edges. The individual elements are up to 9 m high and are produced from a single piece without any unattractive weld seams. Surface finishes and colours. The flush and fully bonded sliding doors are delivered in galvanized sheet steel as standard. For the door leaf and door leaf on the wicket door you can choose between the standard Pearlgrain and smooth sheet steel surfaces. The frame parts are supplied with a smooth surface in both versions. For a harmonious door appearance, the doors including frame parts are optionally available in primed Grey white RAL 9002 or with powder-coated primer in 7 preferred colours, RAL to choose, metallic colours or NCS colours and as an exclusive powder coating in Corten steel.
