Xpanda has been manufacturing roller shutter doors since 1974. These security barriers are manufactured to the highest standard, and like all Xpanda products, are recommended by the police and the insurance industry as key to keeping criminals behind bars. Below are different types of Roller Shutters offered by Xpanda.
In part 7, we will discuss track layouts in detail.
There are four different track layouts available which are common to all types of sectional doors.
The reason for various track layouts is to enable the horizontal tracks to be fitted as close to the roof as possible. This has 2 advantages:
1.The installer does not have to undertake major steelwork fabrication on site, to ensure that the horizontal tracks are fixed securely to prevent lateral movements.
2.The end user has the advantage of utilizing the space under the door when it is open.
The available headroom, which is the space required for the torsion shaft and counterbalance springs, will determine what track layout is used. These are fitted directly above the opening in the case of Standard, Lift Clear of Full Vertical tracks. Low headroom tracks have the springs and cable drums fitted to the rear of the horizontal tracks. Sectional doors up to 3000 high and approximately 5000 mm wide can be push pull operation; thereafter a chain hoist or electric operation is normally used.
