SOHD – Security Considerations
- The panels of a Sectional Overhead Door are made from 2 layers of high strength galvanised steel or zinc.
- Strengthened panels and joints without compromising on energy efficiency and design.
- Window sizes can be reduced and tailored to suit security requirements.
Each of the large Industrial doors have their own engineered features and functions. The Sectional Overhead Door falls within the mid-range for specialised engineered functions while also being mid-range as a security protection barrier.
Engineered Features & Benefits
Tracking Options Explained
Definition: Tracking or rail systems, in the context of sectional overhead doors, refers to the steel structure along which the door frame travels as it raises up into the open position.
Constraints: Roof height, as well as the pitch of the roof dictate the scope of the angle of the tracking as it must be securely fixed to the load-bearing structure of the building – whether that be a high wall, as in the case of a large open warehouse, or a low level roof or ceiling, in the case of a lower more constrained area.
Motor position: In addition to the pitch of the tracking, you must also consider the positioning of the drive motor.
Drive Motor features to consider
- Availability of 3-phase or single phase electricity at location where you want to install door.
- Number of opening/closing cycles needed to perform per day or per hour.
- Speed / power of motor, single speed versus variable speed inverter driven options.
- Temperature and climatic conditions at area where door is to be installed.
- Over-ride of motor in the event of a power outage e.g. ups battery back up (single-phase applications).
Entry Controls – features to consider
- Speed and frequency of opening / closing cycles.
- Standard speed V controlled / variable speed settings.
- Opening: Automatic e.g. loop detection, or manual.
- Adjustable hold-open phase or manual close.
- Operation of door during power outage.
- Temperature control and energy saving.
- Remote control fob.
- Radar presence detector.
