Rolling Steel
Doors
Need a rolling steel door for your warehouse, shop, or storefront? TyGrig installs and services commercial coiling steel doors across Chattanooga and the Tennessee Valley — heavy-gauge, secure, and built for years of daily use.
Tough, Secure,
Built To Last.
Rolling steel doors (also called coiling doors) are the workhorses of commercial buildings — interlocking steel slats that roll up into a compact coil above the opening, saving overhead space and standing up to heavy daily cycling. TyGrig installs, repairs, and maintains rolling steel doors across the Chattanooga, TN area for warehouses, loading docks, parking garages, self-storage, and security closures.
Because they coil overhead instead of running back along the ceiling, rolling steel doors free up valuable interior and overhead space — ideal for tight industrial bays, parking structures, and storefront security. We spec the right gauge, slat profile, and operator (chain hoist, or a motor with the cycle rating your traffic demands) so the door matches how hard you actually run it.
We handle new installs, swap-outs of failed units, and ongoing service — springs, barrels, guides, bottom bars, slats, and operators. Pair it with a loading dock setup, or step up to a high-speed door where traffic is heavy. One local team you can actually reach when a bay goes down, with maintenance plans that keep it from happening in the first place.
