Rolling Steel Doors: Space-Saving Security for Docks, Retail, & Industrial Bays

Upgrade Security, Fire Rating, & Floor Clearance

Rolling steel curtains occupy zero head-room and coil tight above the opening, freeing valuable ceiling space for HVAC, conveyors, and lighting. Engineered slats and end-locks resist forced entry and wind load, while optional fire-rated models deploy automatically to compartmentalize smoke and flames. From distribution centers combating Michigan winters to storefronts needing after-hours protection, Altech Doors supplies, installs, and maintains UL-listed doors that keep operations safe, productive, and code compliant.

What We Offer

Turnkey Installation & Replacement

Select curtain gauge, slat profile, insulation value, and fire rating. Our crews remove old grilles, set new guides & barrels, wire operators, and test every release device before turnover.

Retrofits & Motor Upgrades

Convert manual chain-hoist doors to UL 325-compliant operators, add battery backup, or integrate alarm-activated fire release systems without full curtain replacement.

24/7 Repair & Emergency Response

Damaged slats, failed governors, or stuck curtains can halt receiving. Call anytime—stocked service vehicles roll out fast across Southeast Michigan.

Preventative Maintenance

Annual drop tests, spring counter-balance checks, and curtain alignment adjustments keep doors compliant and extend component life. Our reports outline findings and budget-friendly fixes.
