Hörmann HR 120 A Aluminium Roller Shutter Door
Classic Single-Skin Aluminium Construction for Unheated Industrial and Commercial Buildings
The Hörmann HR 120 A is a robust, economical single-skin aluminium roller shutter specifically engineered for unheated industrial and commercial buildings where thermal insulation is not a primary requirement, but durability, security and architectural appearance matter. Manufactured by Hörmann—Europe's leading door manufacturer—this proven roller shutter design delivers reliable performance across equipment halls, warehouses, storage facilities, agricultural buildings, workshops and light industrial premises throughout the UK.
Purpose-Built for Unheated Applications
Where buildings do not require controlled internal temperatures, the HR 120 A provides an optimal balance between cost-effectiveness and performance. The single-skin aluminium construction eliminates unnecessary thermal specification whilst maintaining the structural strength, wind resistance and security performance demanded by industrial applications:
- Equipment Storage Buildings: Plant hire depots, machinery stores and tool repositories
- Agricultural Buildings: Grain stores, machinery sheds, livestock buildings and farm workshops
- Warehouses & Logistics: Ambient storage facilities, distribution centres and transit sheds
- Light Industrial: Fabrication workshops, vehicle repair facilities and trade counters
- Aircraft Hangars: General aviation facilities and glider storage buildings
- Vehicle Storage: Car dealership storage, motor home facilities and classic car collections
- Leisure & Recreation: Sports equipment storage, marina buildings and outdoor activity centres
119mm Curved Aluminium Profile Technology
The HR 120 A curtain is formed from single-skin aluminium slats with a distinctive 119mm high curved profile geometry. This barrel-optimised concave design provides exceptional structural performance whilst maintaining operational flexibility:
- Profile Height: 119mm—providing greater rigidity than shallow-profile doors for improved wind resistance
- Curtain Weight: Approximately 6.0 kg/m²—lightweight construction reduces motor load and enables larger opening sizes
- Material: High-grade extruded aluminium—corrosion-resistant, durable and maintenance-free
- Curved Geometry: Barrel-optimised profile shape ensures smooth curtain roll-up and minimises storage space requirements
- Interlocking Design: Precision-engineered slat connection provides weather resistance and structural continuity
The curved profile delivers a crucial advantage over flat-slat designs: as door width and height increase, the concave geometry maintains rigidity whilst distributing wind loads more effectively across the curtain surface. This enables the HR 120 A to achieve exceptional size capabilities whilst maintaining tested wind resistance performance.
Exceptional Size Capabilities for Large Industrial Openings
Where standard roller shutters reach their structural limits, the HR 120 A continues to deliver proven performance:
- Maximum Width: 12000mm (12 metres)
- Maximum Height: 8000mm (8 metres)
- Wind Load Classification: Class 2 to EN 12424 (up to 5000mm width as standard, higher classifications available on request)
This capability makes the HR 120 A the ideal solution for aircraft hangars, vehicle maintenance facilities, large agricultural buildings and industrial premises requiring clear span openings without central columns or structural obstructions. The lightweight aluminium construction also reduces structural loading on building frames compared to equivalent steel shutters, simplifying installation and reducing building costs.
Operation Systems: Manual & Electric Drive Options
The HR 120 A is available with two distinct operation systems to suit building usage, access requirements and budget constraints:
SB Rolling Shutter - Spring Balanced Manual Operation
The manually operated SB version incorporates Hörmann's innovative tension spring assembly—a patented technology that counterbalances the curtain weight to enable effortless manual opening and closing:
- Tension Spring Assembly: Custom-dimensioned springs precisely calibrated to door size and curtain weight
- Balanced Operation: Curtain weight fully compensated, enabling one-person operation even on large doors
- Low Maintenance: Long service intervals thanks to engineered spring design and protected spring chambers
- No Power Required: Completely mechanical operation ideal for remote locations or power-failure security
- Operator Retrofitting: Electric drive can be easily added later if usage patterns change
Operation Methods for SB Version:
- Interior or exterior handle (standard)
- Pull rod operation (optional—ideal for high-level access)
- Chain hoist operation (optional—recommended for doors above 3,500mm height for easier manual operation)
The SB manual version is particularly suited to low-frequency openings where power supply is unavailable, unreliable or where operational costs need to be minimised. Agricultural buildings, equipment stores and seasonal-use facilities benefit from the simplicity and reliability of spring-balanced manual operation.
Electric Drive with Direct Motor System or Chain Drive
For frequent-use applications, the HR 120 A is available with Hörmann's proven electric drive systems—engineered for efficiency, longevity and quiet operation:
Direct Drive Motor System (Standard for Most Applications):
- Motor Type: WA 300 R S4 or WA 300 AR S4 direct drive operators
- Soft Start & Soft Stop: Standard progressive acceleration and deceleration protects door components and reduces mechanical wear
- Power Limit Safety: Integrated obstruction detection in Open and Close directions eliminates requirement for safety edges on many door sizes
- Impulse Operation: Momentary button press for automatic open/close cycles with integrated safety monitoring
- Low Power Consumption: Approximately 1 watt standby power when accessories are not connected
- Automatic Timer: Selectable auto-close delays of 30, 60 or 90 seconds
- Emergency Manual Override: Quick-release mechanism for manual operation during power failures
Chain Drive Operator (Available on Request for Specific Applications):
For certain installation scenarios or larger door sizes, chain drive operators are available. The ZAK® gear system can be supplemented depending on shutter dimensions and structural requirements.
Operator Variants:

Surface Finishes & Architectural Integration
Hörmann recognises that large industrial roller shutters play a defining role in building facade appearance. The HR 120 A is available with premium surface finishes to complement modern industrial architecture:
Bright-Rolled Aluminium (Standard):
The natural bright-rolled aluminium finish provides corrosion resistance without additional coating. This economical finish is ideal for functional applications where appearance is secondary to performance and budget control.
Coil-Coated Aluminium (Premium Option):
High-quality factory-applied colour coating on the exterior face provides long-term weather protection and an attractive, professional appearance:
- Standard Colours: RAL 9002 (Grey White) and RAL 9006 (White Aluminium)
- Preferred Colours: RAL 9016, RAL 7035, RAL 9006, RAL 5011, RAL 8028, RAL 7016, RAL 9005
- Special Colours: Any RAL or NCS colour available on request (over 1000 colour options)
- Protective Coating: Polyamide particle-enriched protective paint reduces friction and minimises operational noise
- Durability: Coil-coating provides superior UV resistance and long-lasting colour retention compared to post-applied finishes
The interior face is finished in Basalt Grey (RAL 7012) protective paint as standard when colour-coated options are specified. The bottom profile is supplied in bright-rolled aluminium regardless of curtain finish selection.
