Rapid roll doors are often chosen for warehouses, production facilities, and cold storage areas where doors should not stay open for any longer than necessary. This can add to a location's security and also help with temperature control, as a quick-closing door won't let out much heat or cold. When choosing a rapid roll door, there are some features that you might easily overlook, so that you don't get the best option for your facility. Note a few of those features here before you make your decision for a door for your location.
Speed of operation
A high-speed roller door will usually come with a wide variety of motors and in a variety of materials, and these will affect its overall speed. Note that the term "rapid roll" can mean just about any roller door that works faster than a standard door, but may not denote a certain minimum speed of operation. Check the number of feet or meters the door lifts per second, and note if it's fast enough to protect an interior temperature of a cold storage area or if it will allow forklifts and other such equipment unfettered access to the facility.
A threshold refers to a part of the doorframe on the floor; some rapid roll doors may have a threshold to keep the door locked in place. This may be more common in fabric or vinyl doors that need an extra hold against high winds. A threshold might also provide an added locking mechanism so you have more security against break-ins. However, this threshold could interfere with the ease of forklift traffic or foot traffic, depending on its overall size. Consider carefully this option and weigh your need for this security versus any interruption in traffic it might cause.
Breakaway, self-sealing panels
If you need a rapid roll door in an area with a lot of forklifts, you might opt for one with breakaway panels that self-seal. This refers to panels that actually become separated from one another when pushed, and which then fall back into place and stay attached until pushed again. If the forks of a forklift were to hit such a door, rather than causing damage or tears, the panels would simply detach from one another and then fall back into place just as quickly. This can keep you from having to make consistent repairs to the door or having to replace it sooner than you should because of quick and constant forklift traffic.
