Hormann FST MZ Industrial Sliding Steel Door System

The Hormann FST MZ is a heavy-duty, double-skinned industrial sliding steel door system engineered for high-traffic commercial and industrial environments where durability, safety, and reliable operation are essential. Available in single-leaf, double-leaf, and telescopic (2- or 3-part) configurations, this system is the ideal solution for warehouses, production halls, logistics centres, and vehicle depots requiring wide, unobstructed openings and robust performance.

Key Industrial Applications

• Multi-Purpose Performance: Designed specifically for factories, logistics hubs, storage buildings, maintenance halls, and large plant rooms.
• Large Opening Capabilities: Engineered to span large clear opening widths and heights, facilitating the easy movement of forklifts, heavy machinery, commercial vehicles, and oversized goods.
• Safety Critical Zones: Can be specified in versions with smoke protection capabilities, making it suitable for escape routes and designated safety areas within industrial complexes.

Heavy-Duty Construction and Engineering

• Seamless Design: The door leaf elements are 72 mm thick, fully bonded, and flush-fitted. They feature a patented V-groove joint with concealed fixings, delivering a modern, uniform industrial appearance free from visible screws.
• Superior Stability: Interlocked, toothed labyrinth plug-in profiles combined with threaded rod alignment ensure high torsional rigidity and perfectly parallel door edges, even on the largest door sizes.
• Single-Piece Elements: Individual door elements can be manufactured up to 9 metres high from a single piece of steel, eliminating unsightly weld seams and ensuring a premium finish for architectural industrial projects.
• Integrated Wicket Door: An optional wicket door (personnel door) can be integrated within the sliding leaf, allowing safe pedestrian access without the need to cycle the main industrial door, thereby maintaining thermal efficiency and traffic flow.

Fire, Smoke, and Safety Options

• Certified Protection: Available as a standard multi-purpose door or in special fire and smoke-tight versions (e.g., FST MZ OD), offering tested performance compliant with European fire protection standards.
• Smoke Control: Smoke protection variants can be fitted with stainless steel floor rails or adapted for seamless floor requirements to improve sealing performance in smoke control zones.
• Controlled Operation: The door system can be combined with closing weights and hydraulic track control, offering adjustable closing speeds (typically 0.08 m/s to 0.2 m/s) to ensure safe, controlled closure in busy operational environments.

Industrial Finishes and Customisation

• Corrosion Resistance: Supplied as standard in galvanized sheet steel, providing long-term corrosion protection essential for demanding commercial and industrial climates.
• Surface Textures: Door leaves and wicket doors are available in either Pearlgrain (durable textured) or Smooth sheet steel surfaces. Frame components are always supplied with a smooth finish for a consistent aesthetic.
• Colour Matching: Factory finishing options include a standard Grey White (RAL 9002) primer, or powder-coating in seven preferred RAL colours. Custom RAL, metallic, and NCS colours are available to coordinate with corporate branding or industrial cladding.
• Exclusive Finishes: For architectural projects, an exclusive Corten steel powder coating is available, offering a weathered-steel look with modern sliding door performance.

Premium Stainless Steel Specification

For hygiene-sensitive facilities (such as food processing or pharmaceutical plants) or architecturally demanding sites, the Hormann FST MZ is available in a Stainless Steel V2A (1.4301) version.

• High-Grade Finish: Features a 240-grain brushed finish for a sleek, professional look.
• Complete System: In this specification, all key components—including the door leaf, tracks, cladding, weight boxes, cables, rollers, and support brackets—are manufactured from stainless steel for superior hygiene and corrosion resistance.
• Hardware: Optional stainless steel closing weights can be specified to ensure the entire assembly maintains a consistent material specification.

Applications & Sector Suitability

The Hormann FST MZ is engineered to adapt to the varied architectural and operational requirements of British industry. Its robust steel construction makes it the primary choice for securing large structural openings where durability and ease of access are paramount.

External Building Envelope

Ideal for closing large apertures on warehouses, agricultural barns, and aircraft hangars, the FST MZ provides a secure, weather-resistant barrier. When specified with mineral wool infills, it serves as an effective thermal break, protecting internal stock and machinery from UK weather conditions while accommodating the ingress and egress of HGVs and agricultural plant machinery.

Internal Partitioning & Workflow Segregation

Within manufacturing plants and logistics centres, the door acts as a dynamic partition wall. It effectively separates distinct operational zones—such as dividing "clean" production areas from general storage, or quarantining dusty maintenance bays from assembly lines—without occupying the valuable headroom required by roller shutters.

Environmental & Compliance Control

• Acoustic Control: In noisy production environments, the double-skinned construction aids in sound dampening (up to 31 dB), helping facilities meet workplace noise regulations by isolating loud machinery.
• Fire & Smoke Safety: For facilities requiring strict adherence to building regulations, the door can be specified as a fire-rated or smoke-tight barrier, essential for creating safe compartments and protecting escape routes in commercial complexes.
• Thermal Regulation: Suitable for large plant rooms and boiler houses where temperature containment is necessary.

Operational Flexibility

Standard units are supplied for manual operation, offering a low-maintenance solution for low-frequency use. For high-traffic areas, such as busy loading bays or distribution hubs, the system can be fully automated to ensure seamless workflow integration and reduced operator fatigue.
