Fast acting doors for standard logistics
To separate areas within your premises safely and efficiently while reducing maintenance costs when no other special feature is required.
Indoors, traffic can be busy and space restricted, increasing the risks of contact every time traffic passes through a door. It is therefore better if the door opens as late as possible and closes again quickly to protect the different areas within your premises without at the same time increasing risks caused by rubbing against the curtain.
The JAC high performance fast acting door for standard logistics is a roll-up door to save space at floor and lintel level, and its numerous flexible stiffeners uniformly distribute pressure over the whole of the frame to withstand strong draughts and increase insulation. Its flexible closing edge can be distorted both vertically and horizontally and is responsive over a height of 40 cm reducing repair and maintenance costs.
Each time it opens, it frees access at the last moment without posing a risk if touched, then closes again at the same speed – twice as fast as traditional fast acting doors – without endangering users, vehicles or packages. It therefore reduces accidents and production stoppages, but by also shortening the time it is open, energy consumption for heating or cold production is reduced between two areas with different environments.
Designed for corrosive and aggressive environments, the frame and mechanisms of the JAC high performance high-speed flexible door for standard logistics are in multi-composite materials which are more resistant to corrosion than stainless steel. Multi-composite, because a formulation and design specific to each mechanical and kinematic function significantly increases its resistance to galling, twisting and denting when compared with welded solutions.
They are smooth and wear-resistant without the paint or crevices inherent in welded structures. The mechanisms are more corrosion-resistant than 316L stainless steel. The toughness of the uprights, their ability to absorb an impact without becoming permanently distorted, and the absence of paint guarantees a durable, corrosion-free appearance.
External flexible folding doors
To provide effective protection from the environment, our high-speed external flexible doors use Trekking folding technology to provide greater wind resistance, up to category 5, along with better insulation.
The Trekking technology for JAC automatic folding flexible doors provide greater wind resistance by increasing the number of stiffeners distributed from top to bottom of the opening. They tension the curtain evenly down to the bottom of the slides to provide better weatherproofing. They distribute pressure over the whole of the frame uniformly thus providing reliable and continuous operation, even when subjected to a high wind load, without jamming or flapping and without any unnecessary and hazardous weight at the bottom.
The closure edge is flexible and deformable both vertically and horizontally. With no rigid feeler bar or system to restrain the curtain in the slides, it can distort without knocking the vehicle on contact. Directly responsive over a height of 40 cm, it registers the distortion and retracts above the obstacle. This patented property allows it to open just in time to provide access, and to close again immediately after at the same speed, thus reducing the exposure time of your building and energy costs due to air exchanges by up to 32%!

Lastly, because the curtain does not roll up on itself, it can accommodate flexible wall insulators of any thickness suited to different insulation requirements, for example to stand up to cold or contain heat (in an oven for example), or to reduce acoustic transmission (in the case of high noise levels for example).
The frame of JAC fast acting external flexible doors is independent of the building. Produced in steel for the widest spans (up to 200 m²), they can be made, for dimensions up to 6 x 6 m, in new materials, more corrosion-resistant than stainless steel and thermal break by virtue of their nature. Depending on the options chosen, the direct motor drive is either built into the transom or protected under a cover, with a smaller number of moving parts for easier maintenance and longer service life. Numerous options are available to adapt these high-speed doors to your requirements regarding transparency, thickness and density of the curtain, non-powered opening and transom shapes to provide access to the motor drive from the front, top or bottom. For greater productivity and uninterrupted service from the fast acting door, even in the event of an incident, its slides are of sufficient size to allow it to operate continuously even if its stiffeners are accidentally distorted.
