Both of the PVC high speed door and stacking door/folding up door have the advantages of automatic opening and closing, rapid lifting, heat insulation, anti-fouling, and energy saving. The similar appearance and performance index characteristics also make customers difficult to choose. What are the differences between such a stacking door and PVC rapid rollup door? In terms of appearance, the wind-resistant ribs of the strap-up stacking door are combined with the curtain and integrated with the curtain, while the pvc fast-rolling door applied aluminum alloy profile curtains as the reinforce bar for wind-resistance. The wind-resistant aluminum bar appear on the outside of the curtain as we can see. In terms of lifting methods, industrial stacking doors applied the shaft cylinder to rotate and the straps to vertically raise the curtains, so that the curtains have a practical effect of overlapping and stacking; normal type rapid doors used the rotation of the door hinge to immediately achieve the goal of rolling up the curtain. Wind resistance of Fast rolling door is the difference between a garage stacking door and a high-speed rolling door. In view of the large total number of wind resistant ribs, the stacking door has stronger wind resistance and can be assembled outdoors. The actual effect of the wind resistance of the rapid soft curtain rolling door is not that good as stacking door, and it is more suitable for indoor use, mostly in industrial production workshops. The strapping stacking door produced by Shenzhen Hongfa Door and the PVC fast rolling door have difference also on running speed.

It can meet high-performance logistics and clean places, and save energy, high-speed automatic shutdown, improve working efficiency, and create a better working environment for the installation sites, therefore has become a good option of industrial doors.

High-speed doors are door systems, mainly used in industrial applications. They are technical enhancements of the generally known sectional doors, PVC fabric doors or roller shutters. The main difference is that the durable construction provides a higher operating speed and they are able to sustain a higher number of cycles (opening and closing cycles) and require lower maintenance and repair cost. Depending on the intended field of application, horizontal or vertical operating door types are available. There are many reasons why you should use a high-speed door. Here are some good ones: Speed- traditional roller shutter doors move extremely slowly while high speed doors can fully open in as fast as 1.7 second which means minimised cycle time, thus decreasing energy loss and minimising the chance of forklift impact, improving productivity, and lowering the risk of costly repairs. Safety – Manual roller shutter doors are heavy and can damage your back and automatic roller shutter doors are just too slow, allowing them to be easily damaged. High speed doors have in built safeties to prevent closing when obstructed, and a wireless reversing bottom edge reverses door when coming in contact with an object. Window Kombypanels can also be added to enhance visibility when closed or opening, both maximising safety to prevent personnel harm and vehicle damage, and in situations where security is the main concern our Komby Door is the perfect fit, the compromise and best of productivity and security in one.

BENEFITS OF HIGH SPEED DOORS Improved work environment With high speed doors, it easier for people and equipment to move more efficiently around the premises. No one is required to wait for doors to open or to manually open heavy doors. They also enhance safety which is vital in any working environment. Reduced pollution High speed doors are designed to reduce noise and odour pollution. This is why they have become so important in recycling and food industries. In these industries, environmental control is of paramount importance. Maintaining steady temperature For many industries, the temperature of a whole building or certain areas of a building must be maintained. Having to heat or cool the area every time a door is opened will significantly increase the operating costs. Due to their speed of both opening and closing, the heat lost from the premises or gained from the outside is minimised. This will increase the efficiency of premises temperature control hugely. Time-saving With a high speed door, you don`t have to wait for a slow door to drag itself upwards. This saves a lot of time and energy. Reduced contamination In highly sensitive environments, a speed door will help minimise the impact of dirt or dust that comes from outside into the premises. This will help keep the space clean and anything that is being processed is more likely to be of better quality.
