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.
