ISO SECTIONAL OVERHEAD DOORS
Modern Door Concept With Optimum Performance
Guardian's ISO range of sectional overhead doors is a result of the most modern design and manufacturing techniques that are currently available. These doors are robust, exceptionally durable and available in both 40mm and 60mm panel sizes. The metal end-caps, metal re-inforcing sections and the anodised aluminium bottom section, invisible from the outside, are generously sized. The use of anodised aluminium top profiles of different heights means that the ISO sectional overhead door can always be offered with an optimum overlap relative to the lintel.
All these characteristics combine to make the ISO sectional overhead door a high quality, hard-wearing product that not only improves the appearance of a building but also saves energy and reduces maintenance bills. Easy to integrate into modern architectural designs and fully compliant with the most recent technical requirements in terms of safety and ease of use. ISO sectional doors can be ordered with either manual or electric operation.

T240 Track System - MAX DOOR SIZE 22m2
The T240 system is used when headroom of 240mm is available above the clear opening. A rectangular tube profile is mounted at the rear of the tracks. The spring assembly is fastened to this tube. This system can also be used if headroom above the clear opening is less than 240mm when the sectional door will remain visible in the clear opening when the door is fully open.
T340 Track System - MAX DOOR SIZE 22m2
The T 340 system is suitable for standard situations. This system is used when a headroom of 340 mm is available above the clear opening. A rectangular tube profile is mounted at the rear of the horizontal tracks. The spring assembly is fastened to this tube.
This type of track system is an excellent solution in cases when the available headroom of 340 mm is not suitable for other track systems. For example, if a glazed element is located above the clear opening or the wall above the opening is constructed from cellular concrete. In the first instance, the spring assembly would be visible from the outside. In the second instance, the material above the opening is not robust enough to carry the weight of the spring assembly.
T400 Track System - MAX DOOR SIZE 50m2
The T400 system is used when a headroom of 700 to 3400 mm is available above the clear opening. The vertical tracks follow the wall line until the roof is reached and then curve through the appropriate angle to lie parallel to the roof. The spring assembly is mounted to the vertical wall just under the roof.
T400hf Track System - MAX DOOR SIZE 18m2
The T400hf track system can be selected when you have a headroom of 1700 mm up to a 4500 mm. The vertical tracks will follow the wall up to the roofline. The springs are pre-assembled and pre-mounted on to a spring beam and positioned 500 mm above the clear opening height. The advantages of this system is faster installation and easy access for future repair and maintenance. A minimum high-lift of 1375 mm and a maximum door width of 4500 mm are the systems parameters.
T450 Track System - MAX DOOR SIZE 50m2
The T450 system is used as standard when a headroom of 430 to 700 mm is available above the clear opening. The spring assembly is fixed to the building wall in this case
T500 Track System - MAX DOOR SIZE 28m2
This track system is used when the available headroom is sufficient to allow the sectional door to open vertically. The spring assembly is fixed to the wall at the top of the tracks.
T500 Track System - MAX DOOR SIZE 18m2
This track system is used when the available headroom is sufficient to allow the sectional door to open vertically. The spring assembly is fixed to a mounting arrangement at approx. 500 mm above the clear opening. The door width may not exceed 4,000 mm when this system is used. The low-level spring assembly simplifies drive and spring arrangement maintenance and repairs.

Wicket Doors
The advantage of a permanent wicket door is that the doors for pedestrians and goods are completely separate. This increases safety, ease-of-use and the stability of the sectional door. A permanent wicket door is installed in the façade next to the sectional door, where the design and panel structure of the wicket door and top panel match the structure of the sectional door, unifying them and making them both architecturally and aesthetically pleasing.
Emergency Exit
If you intend to use the built-in wicket door as an emergency exit, talk to the local authorities first and enquire about the regulations. The authorities stipulate the conditions that the wicket door must meet, depending on the number of people working or otherwise present in the building. As a rule, four aspects determine whether a wicket door is suitable as an emergency exit: the type of lock, the door width, the door height and the threshold height. Lastly, an integrated wicket door must always open outwards, as is required for any door that serves as an emergency exit.
Panic Lock
A wicket door that is to function as an emergency exit must be fitted with a panic lock. Various types of panic locks are available – see page 61 for more information. A wicket door with a panic lock can always be opened using the latch on the inside, even when the deadbolt is secured.
15mm Threshold
To prevent the risk of tripping during escape, Guardian has developed a low threshold height of 15mm. A threshold of this height meets every national guideline on escape routes within the EU.
- Side pass door incl.
- Fascia to main door height (clear opening side door = production width - 240 mm)
- Electric strike, including cabling up to side door leaf (without control)
- Fixed knob

- Low sill, 100 mm
- Reduced-height sill (< 15 mm)
- Door spy

Planned preventative maintenance
See our maintenance section or contact us for more information. Guardian's repair and maintenance services and engineers are accredited to the DHF's TS004 Repairs and Maintenance standard.
It is a legal requirement - as failure to show evidence of maintenance could mean prohibition & enforcement notices being served and fines up to £5000 and imprisonment for 2 years. 'Safety In Use' - the New European CEN Standards legislation - states that all types of door should be maintained in an efficient state, in efficient working order and in good repair. For further clarification visit www.dhfonline.org.uk.
Routine maintenance prolongs the operational life of the installation and ensures that the installation is kept in good working order - helping to prevent accidents and damage which in turn results in down time, effecting work flow, productivity and resulting in loss of revenue. It assists in identifying potential problems which can easily be rectified.
