A repair bay lives or dies on clear space. Lifts, engine hoists, tool chests, and a line of cars — the last thing you need is overhead door hardware eating the room above your lifts. That's exactly why so many shops spec commercial roll-up doors: the steel curtain coils straight up into a drum above the opening. No tracks running back across the ceiling where your lift posts and lighting go, and when the door's open, it's gone — full headroom, full width.
We're Steel Curtain Doors, a commercial roll-up door company in Suwanee, Georgia. We sell buy-direct with pickup at our shop, and our crews install across metro Atlanta.
### What shop owners ask us about
- Clearance over lifts. A two-post lift needs real overhead room. A roll-up door's drum sits tight above the opening — check your drum clearance against your tallest lift setting when you measure the opening.
- Door size. Most single service bays take a 10-ft or 12-ft wide door; 12 ft gives a tech breathing room pulling trucks in. Bigger shops run 14-ft or 16-ft doors for dually and box-truck bays.
- Chain hoist vs. electric operator. Bay doors cycle dozens of times a day. A chain hoist is simple and bulletproof on smaller doors; an electric operator earns its keep on the wider bays your crew opens all day.
- Security. Roll-up doors take slide locks and keepers; padlocks and latches hold the curtain down after hours when the shop's empty.
- Dust, fumes, and seals. Brush and jamb seals plus a header seal cut the dust and exhaust creep between bays — a cheap upgrade for shops that share a building with clean work.
- Insulated models. If you've got a customer waiting area or climate-controlled shop, insulated curtain models are available — ask about cost and lead time.
### Repairs happen — plan for them
Shop doors take hits: a mirror clips a guide, a forklift kisses the curtain. Roll-up doors are made to keep working through that — individual slats and guides are repairable, and because the whole curtain is steel, small dents don't jam the door the way a bent sectional panel does. When something does need service, call a commercial door tech — roll-up springs are under serious tension and aren't a DIY job.
### Getting a door for your shop
Measure each bay opening (width, height, and side room — our How to Measure guide covers all three), decide on hoist vs. operator, and send the numbers through the quote request page. We'll price the right Janus model for each bay.
