Detailed information about the product High Speed Door
It is made of strong, 0.8mm thick polyester fabric with integrated aluminium ribs, giving resistance to air pressure and moderate wind forces.
All panels are replaceable.
Door leaf- Construction
The door leaf is made from several sections of fabric, connected with each other by horizontal aluminium ribs. Each section can be replaced independently. The door leaf rolls up above the door opening and requires little space. - Top
The top of the fabric is connected to a fabric roll, located in the header box above the door opening. - Bottom
The bottom bar is equipped with break away tabs that slide through the side columns. The bottom bar contains an optical safety edge and a polyester seal to the floor. The bottom bar is made of anodised aluminium, reinforced with a steel profile. - Side
The door leaf is constructed with aluminium ribs that run through the side columns, to keep the door leaf in the side columns when exposed to air pressure.

- General
The door leaf is guided horizontally by anodised aluminium side columns. When the door is opening or closing, the breakaway tabs on the bottom bar and the aluminium ribs on the door leaf slide through these side columns to keep the door leaf straight. The side columns are connected to the wall. - Break-away tabs
The bottom bar is equipped with flexible tabs which break away under impact. When the door is hit by a vehicle, the entire bottom bar will be pushed out of the side columns. The pneumatic sensor sends a signal to the operator and stops the door movement immediately.
The break-away tabs can be manually repositioned into the tracks in a few seconds, without the use of tools. For safety reasons, the door can then only be operated again, after pressing the reset-button on the control unit.
- Fabric roll
The fabric roll is installed in the header box above the door leaf. Its function is to roll up or down the door leaf by means of the operating system. The door leaf is tensioned by its own fabric and bottom bar weight. - Header box cover
For use in dusty and dirty environments or for aesthetical reasons, an optional aluminium header box cover is available to enclose the fabric roll and/or the operator.
