HIGH SPEED DOOR CURTAIN

 

In cases of heavy impacts or after many years of operation of the high-speed door, it is possible to notice tears in the pvc curtain. The latter can be replaced with a new curtain or in extreme cases it is advisable to replace the industrial closure with new automatic high-speed doors.

In fact, when replacing the curtain, it is a good idea to have all the safety accessories checked, because if they are worn, they can create a risk to personnel or material where the high-speed door is installed. Inside the pvc curtain of the old high-speed doors is a safety edge that allowed the door to open automatically when touching the bottom of the curtain. With the new safety edge, the door avoids the risk of crushing by using new 2 metre high light curtains barriers to reduce the possibility of collision and breakage of the curtain.

Roller shutter door curtain

High-speed roll-up doors are characterised by a smooth pvc curtain with or without a porthole with a space-saving vertical opening. This door is characterised by the curtain rolling up at the top inside a protective casing. It is installed both inside and outside of halls with dimensions of less than 6 metres in height.

The curtain is free from straps that raise the curtain. In fact, the roll-up door is opened by zips installed on the sides of the PVC curtain that slide on tracks inside the door post. This system allows the high-speed door to be hermetically sealed and rigid, even withstanding strong winds.

The curtain of the high-speed roll-up doors is 1200 g and is welded electrified with precision machines and checked at every stage by specialised personnel to ensure quality and strength even after many opening cycles.

Replacing the pvc curtain of the high-speed doors is easy, but it is important to check the correct side of the curtain and the correct winding direction given by the motor. After installation, it is necessary to check the end stop of the opening and closing of the rapid door; for instructions, please refer to the installation and use and maintenance booklet.

High speed folding doors curtain

The fold-up door, unlike the roll-up door, has a curtain that is raised upwards by means of galvanised steel straps and tubes. The curtain has transparent portholes and pockets to ensure the door can be opened quickly.

In contrast to the roll-up door, this industrial closure is not airtight, but offers a wider opening even in external areas of the hall exposed to strong winds.

There are different types of folding doors with different technical specifications and performance, let’s take a look at the characteristics that identify them:

  • Speed fold-up door. As described above, it is a single curtain with visible straps. These rapid doors are placed in areas where vehicles and few personnel pass through for safety reasons.
  • Dual-air double curtain speed door. This type of door has the pvc curtain positioned on both sides of the industrial closure. Thanks to this feature, the straps, which remain inside the curtain, lift the galvanised steel latticework. Double curtain high-speed doors are more resistant and reach even large dimensions; in fact, they are installed in warehouses and warehouses located even in windy areas such as airports and naval ports.

When to replace the high speed door curtain ?

The rapid door is made of PVC sheeting, i.e. a resistant and flexible material, it is easy to wash, which is why rapid doors are used in areas where it is necessary to keep a clean, sterile or humid environment such as: car washes, pharmaceuticals, foodstuffs, biocells …

Thanks to the strength of the tarpaulin, the speed doors remain intact for many years. Heat and shocks can ruin the ends of the transparent tarpaulin portholes, which, being made of normal plastic, wear out faster.

The replacement of the curtain of high-speed doors occurs especially when it suffers heavy impacts from lifting equipment that cut the curtain or disconnect the pvc welds. For this reason, Giesse Uk installs the two-metre high Safety light barrier sensors, which allow the rapid door to open automatically, avoiding shocks and breakages.
