The aluminium alloy hard speed gate can withstand up to 100,000 opening and closing cycles, and up to 100,000 opening and closing cycles in a single maintenance interval.

Due to its sturdy structure, The high -speed rolling door can still thnction normally even when the wind speed is as high as 120KM/H,And it isvery suitable for use as an external door. 

For all entrances and exits that often travel in both directions, the installation of such a door provides a clear view, effectively avoids accidents, and ensures unimpeded transportation.

Door curtain structure

Components: aluminum alloy curtain, soft connection rubber strip, load-bearing rubber chain, guide wheel and other parts

>The thickness of the aluminum alloy curtain is 1-200mm, the surface is anodized and organically colored, the tensile strength exceeds 230B/MPA, in line with the GB/T5237.1-5-2000 standard, the color is pasteur gray, and there are two optional colors of aluminum alloy sand white and Chinese red;

>After connecting the aluminum door curtain station through the soft connection rubber strip, the folding life of the soft connection part is more than one million times;

>The angle chain load-bearing design makes the door curtain joint not stressed, the door curtain does not change its shape, and it can maintain flatness after a long time;

> When the door body is running, it slides in the aluminum alloy track through the guide wheel made of polyampheta, and there will be no friction and dry sound when running at high speed.

Security system

1. Infrared safety protection electric eye: there are counter-radio eyes on both sides of the door frame, and there are objects under the fast door to keep the door open; When the door body is lowered, there is an object passing through, and the door body will open to the * open position, and then delay the descent when there is no obstacle below.

2. Bottom safety protection edge: When the door body is descending, because the object is in the blind spot of infrared safety protection, when the door body is pressed against the obstacle below, the door body will rebound quickly in the door opening, and the effective object or pedestrian below the household will avoid accidents.

3. Light curtain protection system: this configuration is a unique and effective safety protection method of BIST industrial door, a grating wall is installed in the direction of the heavy straight place, it is usually composed of 18 groups of light heads, using 485 communication protocol, and according to the actual height of the door curtain body to calculate the position of the door curtain and give an effective measure to protect pedestrians or objects.
