Industrial, security, self-storage.
Heavy-duty rolling steel, security grilles, and counter shutters for industrial, retail, and self-storage facilities. Repair, motorization, and full installation. Written quote, COI same day. Cornell, Cookson, Wayne Dalton authorized, real Metro techs since 1979.
Metro repairs and installs commercial rolling steel and coiling doors across the Atlanta metro, heavy-duty insulated curtains for industrial bays, perforated security grilles for retail closeouts, counter shutters for service windows, and fire-rated coiling doors for code-required openings. Cornell, Cookson, and Wayne Dalton authorized. COI same day, never subcontracted.
Cornell, Cookson, Wayne Dalton, we order direct, install to spec, and stand behind the manufacturer warranty plus our lifetime workmanship.
Rolling steel binds when the brake is off-spec or the motor limits are wrong. Every install gets a documented calibration so the door coils and stops cleanly through its full life.
A jammed curtain on a loading bay or retail closeout is a downtime emergency. We dispatch on a priority track, diagnostic the same day, parts ordered same day, often resolved within 24 hours.
Three components determine reliability: the curtain construction, the motor and brake, and the limit calibration. Get any one wrong and the door binds, brakes wear out, or the motor burns up.
Curtain construction. Three categories: interlocking steel slats (standard industrial, 18 to 22 gauge, galvanized or powder-coated), insulated foam-core slats (cold storage and conditioned bays, R-7 to R-12 with thermal break), and perforated/grille curtains (retail security, visibility through the door when closed, lockable for after-hours). Slat thickness drives cycle life, thinner slats deflect under wind load and bind in the tracks over time. We spec to wind exposure and cycle count.
Motor and brake systems. Standard industrial coiling doors use a hand-chain hoist as backup, an electric motor for normal operation, and a motor-mounted brake to prevent free-fall. Heavy-cycle and large-opening doors require a governor brake (centrifugal brake that engages on free-fall, code-required for some configurations). We verify the brake type matches the door size and the curtain weight before the install signoff.
Security applications. Anti-pry retail grilles use thicker slat tabs and reinforced bottom bars to resist forced entry. Bullet-resistant rolling steel exists for cash-handling areas (UL 752 Level 1 through 8, most retail uses Level 1 or 2). Fire-rated coiling doors are a separate category, UL-listed, 1.5-hour to 4-hour ratings, automatic close on fire signal. See our fire-door page →
Self-storage scale. A 200-unit self-storage facility has 200 individual rolling steel doors, light-duty 24-gauge slats, manual operation typically, but high cumulative cycle count across the facility. We service self-storage at facility scale: blanket service contracts, locked-in slat pricing, and priority response on damaged units (storage tenants notice fast).
Our install process. Site walkthrough, opening dimensions, headroom (rolling steel needs 18–24 inches headroom for the coil), wind/security exposure, motor type, brake spec, electrical rough-in. Written quote within one business day. Curtain + motor + brake + tracks delivered together. Install + cycle test + brake test + limit calibration. Operator and emergency-stop training before signoff.
If your curtain is binding, your motor's burning out, or your brake's off-spec, call (770) 526-1214, we keep common slats and motor parts on the truck.
First diagnostic: pull the motor off-line and try a manual hoist. If it still binds, the slats or tracks are damaged (often after a forklift impact or a winter freeze). If it manuals freely, the motor limits are off and we recalibrate. Either way, same-visit fix when parts are stocked.
Two causes: the motor was undersized for the curtain weight (common when previous installer cut corners), or the brake is dragging because the lining wore out. We size the replacement motor to current curtain weight + 25% safety margin, and replace the brake assembly if it's dragging.
Free-fall on a heavy curtain is a serious safety incident, the door can crush vehicles or pedestrians. We install or rebuild the governor brake to current code, document the test, and tag the door with the inspection sticker. Required for some insurance carriers.
Rolling steel, coiling, and roll-up doors share one failure pattern: the door works until the day it does not, and that day the bay is closed. Metro repairs every part of a commercial roll-up door, from a single self-storage unit door to a 24-foot insulated dock curtain, and most repairs are finished on the first visit.
What a roll-up door repair call covers. The curtain and its slats, the end locks and wind locks that keep the curtain in the guides, the barrel and the counterbalance spring inside it, the guides and their wear strips, the bottom bar with its astragal seal and safety edge, the hood, the locks and slide bolts, and on motorized doors the operator, brake, limits, and controls. A tech opens the hood, checks each of those in order, and quotes the repair in writing before touching a wrench.
The five repairs we make most. Slat replacement after a forklift or truck strike, usually same-visit for common 18 and 20 gauge profiles. Counterbalance spring re-tension or replacement when the door has gone heavy on the hoist chain or the motor is straining. Guide realignment and wear-strip replacement when the curtain scrapes or binds on one side. Operator and brake service, from a burned motor to a dragging brake lining to limits that stopped where they should not. And bottom bar and astragal replacement when the door no longer seals to the floor or the safety edge stops reversing.
Manual roll-up doors. Most self-storage unit doors and many small-shop doors are push-up or chain-hoist doors with no motor at all. The usual complaints are a door that will not stay up, a door that takes two people to lift, or a curtain that jumped a guide. All three are spring tension, guide, or lock repairs, and a tech carries the parts to fix them without pulling the door. Multi-unit facilities get a per-door price for a walk-through repair pass, which is how a 200-door site keeps every unit rentable.
Emergency roll-up door service. A dock door stuck open is a security problem and a stuck-closed one is a revenue problem, so both go to the front of the queue. Call (770) 526-1214, tell dispatch it is a commercial door down, and a Metro commercial tech is routed the same day across the Atlanta metro. If the curtain cannot be made safe on the first visit, we secure the opening and return with the parts.
Repair or replace. A curtain that has been struck once is repairable slat by slat. A curtain that has been struck repeatedly, or one whose slats have corroded through, is a replacement, and so is a door whose barrel spring has failed twice because the door was undersized for its opening. We tell you which it is with the numbers behind it, and if the answer is replacement the quote covers a properly specified curtain, motor, and brake, itemized. Overhead sectional doors are covered separately on our commercial overhead door page, and high-cycle fabric and speed doors on the high-speed door page.
