Industrial High Speed Roller Door for Factory and Warehouse

Hard fast door, it is a door with high utilization rate on the market at present, the door board is made of aluminum alloy material, divided into hollow type and heat preservation type. The most common color is silver and gray, we are usually using aluminum alloy foam door plate, the middle can be added perspective window, enhance the lighting performance of the door, its material is polycarbonate, with high temperature resistance, wear-resistant advantages.The door plate is made of thickened double-layer galvanized color steel plate, and the interior is made of high-density polyurethane foam material, which has the advantages of heat insulation, sound insulation and heat preservation, and it is applicable to large warehouse and factory gate.

Hard fast door features:

1. Door body operation: the guide wheel is used to slide inside the guide wheel of aluminum alloy. There is industrial lubricant between the guide wheel and aluminum alloy to ensure high-speed operation and protect the parts of the door body to reduce component losses caused by friction.
2. Control system: the torque ring, position ring and speed ring of the servo system are fully closed;Servo system with braking function, without external electromagnetic brake pad can make the motor stop at the designated position, make the door body stop at the limit position exactly. It has memory function after power failure. It can be reset directly without adjustment after power failure and manual operation.
3. Door soft connection: The door panels are sealed by rubber strip. The folding life of the soft connection can reach millions of times, ensuring that the rubber strip will not be aging and deformed too fast.
4. Safety device: On both sides of the door body is equipped with an electric eye, when there is an obstacle under the door body, the fast door will automatically maintain the open state, wait for the obstacle to leave, then automatically fall.
5. Door color: the color is usually aluminum alloy primary color, there are also a variety of paint colors, pearl white, Chinese red and other colors.
6. Voice isolation: start with low noise, galvanized pulley block is equipped with adjustable ball bearing and wear-resistant rubber wheel, ensuring the door to open and close quietly.

Aluminum alloy fast door is fast lifting barrier isolation door, the main role is rapid isolation, so as to ensure the air quality of the workshop dust-free level. It has multiple functions of  insulation, cold insulation, insect-resistant, windproof, dust proof, sound insulation, fire prevention, odor protection and so on, widely used in food, chemical, textile, electronics, supermarket, freezing, logistics, warehousing, and other places, can be extremely meet the high performance logistics and clean place, it has advantages of energy saving, high speed automatic shutdown, high work efficiency, creating better working environment, etc.

Hard fast door can achieve both rapid rising and falling and anti-theft performance at the same time while the traditional automatic door can not. It is suitable to be used as garage door very much due to its ability of assured guard against theft with the high intensity of aluminium alloy. Especially in some large public garages, it can achieve a large number of vehicles in and out at any time every day, and at the same time, it can ensure safety. Hard fast door can be used stably for a long-term although the price is more expensive compare to PVC fast door. Its Cost performance is very high!
