Low Headroom and High Security
The Spiral® Low Headroom Hurricane Zone Door brings high speed and high security to applications with unique space limitations in High Velocity Hurricane Zones. Whether headroom is severely limited because of low ceilings, joists or other overhead obstructions, the LH-HZ is engineered for all types of low lintel challenges.
Clean lines and a refined structural design gives the Spiral LH-HZ door a stylish and high-tech look. With 192 powder coat options, the door can be customized to compliment any colour palette. Even without the custom colors, the anodized aluminum slats will not corrode, so you can count on that look to last for many years even under the worst weather conditions, including hurricanes.
