Rolling steel doors in Baltimore County

A rolling steel door coils above the opening instead of tracking back into the building. This makes it the standard choice wherever ceiling space is short or the opening takes daily punishment. In Baltimore County, this describes most of the older industrial stock. We cover shops around Dundalk and Halethorpe, buildings behind Eastern Avenue in Essex, and the self-storage and service bays between them.

We supply and install new rolling service doors. We also service the ones already hanging, no matter who installed them. The common county repair is a curtain damaged by a forklift, or an end lock that let a slat wander out of line. We also replace counterbalance springs that break after 20 years of cycles, or chain hoists that stop taking the load.

When a door is replaced rather than repaired, the measurement matters more than the catalogue. Older Baltimore County openings are rarely square, and headroom is often less than a spec sheet assumes. A technician measures on site so the door that arrives fits the actual opening.

Wind load comes up on buildings closest to the water at Sparrows Point and along the Back River. Windlock construction on those openings gets engineered, not guessed. The calculation goes into the submittal.
