The main categories of high speed doors are hard high speed doors and soft high speed doors. Hard high speed doors mainly refer to aluminum high speed doors, and soft high speed doors mainly refer to PVC high speed doors. Now let's learn about hard high speed doors and soft high speed doors. Some of the similarities and differences of them. The hard high speed door is the same as the soft high speed door in that: 1. Compared with traditional rolling shutter doors, their switching speed is very fast, which can reach 0.5-2.5M/S (adjustable). 2. They are all high-tech products, and there are many ways to open doors, such as radar, remote control, geomagnetic, photo cell and so on. 3. They are all very durable and can withstand up to 100,000 to several million openings and closings. 4. They all look great and can be customized with view windows and colors. The difference between hard high speed door and soft high speed door is: 1. Hard high speed door more firm, more anti-theft, suitable for outdoor doors, soft high speed doors are lighter and more suitable for indoor doors. 2. Hard high speed doors cost more and are more expensive, while soft high speed doors cost much less and are much cheaper. At the same time, t

There are many functions of high speed doors, including: heat preservation, energy saving, sealing, high efficiency, dustproof, sound insulation, lighting and other functions. But in the face of all kinds of high speed doors, how do we choose and customize the high speed door that suits us? The following experience is for your reference: 1. First of all, we need to look at the main functions to choose the type of high speed door. If strong wind resistance and anti-theft are required, we should choose a hard high speed door(aluminum high speed door), otherwise we can consider a more economical soft high speed door, that is, a PVC high speed door. 2. In terms of lighting, if the requirements for lighting are relatively high, you can consider making more view windows, otherwise you don't need view windows. 3. From the perspective of sealing, if the sealing requirements are high, you can consider the zipper high speed door(auto recovery high speed door), otherwise you can consider the economical ordinary high speed roller door. 4. If it is dedicated to the cold storage, you can consider the cold stor

In dust-free workshops or clean areas, air showers are important facilities to ensure a clean environment. Its commonly used AB door scheme is: when people enter, door A opens through the automatic sensing system, and door B remains closed at this time; when people pass through door A and enter the air shower area, door A automatically closes to perform necessary air shower dust removal. Operation: After completing the air shower, door B opens and personnel leave the air shower room. At this time, door A remains closed again. This design effectively avoids direct convection of internal and external air, ensures the air shower effect, and improves the cleanliness of the sitting-free workshop. At present, more and more companies choose fast rolling shutter doors as the AB door solution for air shower rooms. The fast rolling shutter door is perfectly adapted to the working environment of the air shower room with its efficient opening and closing speed, excellent sealing performance and intelligent sensing system. When door A or door B needs to be opened, the fast rolling door can respond quickly and open automatically; when people pass through, the door can be closed immediately to ensure the sealing of the air shower room and prevent external dust from entering. This efficient door system not only improves production efficiency, but also greatly enhances the cleanliness of the workshop. Hongfa Doors is a professional industrial door manufacturer.

Recently, customers often come to inquire about a problem. The automatic metal sectional garage door body always shakes during the descent process. The customer is worried that the door body will fall and personnel safety accidents may occur. This article will introduce to you the possible problems based on this question. and its solutions for everyone to take a look at. Causes and solutions for shaking when the sliding door descends 1. The track is loose. Some unprofessional installations may cause this problem. The screws of the track are not fixed with the body or the square brush, which is easy to cause the entire lift door to fall off, which is easy for people. In this case, it needs to be screwed. Or just add wire; 2. The torsion spring shaft is loose. If this part is not installed in place, the entire transmission shaft will shake, which will affect the door panel. In this case, the spring spring needs to be tightened, and then check whether the door body is fragrant or not. dithering; 3. The twisting force calculated does not match the weight of the door panel. Generally, the door body shakes because the twisting force is greater than the weight of the door panel. The entire door will be pulled beyond the normal range of motion, and jitter will occur; the opposite twisting force will occur. When it is less than the weight of the door panel, it will open slowly, and even cause the wire rope to bear too much weight, causing it to break and the entire door panel to fall down. In order to avoid total accidents, it is necessary to match the twisting force of the corresponding force, loose tracks, loose torsion shafts and mismatched torsion load are basically the causes of door panel jitter. This is also a problem for most low-priced sliding door manufacturers. In order to cont
