Door type
Commercial Garage Doors & Roller Shutters
Commercial doors get specified on cycles and load, not on catalogue size. Getting that wrong is why some businesses replace a motor every two years.
Quick answer
Commercial Garage Doors & Roller Shutters: the essentials
Commercial garage doors and industrial roller shutters are specified according to opening size, curtain weight, required duty cycle and applicable workplace safety requirements, rather than on size alone. A commercial door may cycle 30 to 60 times daily against three or four for a residential door, so springs, drums, bearings and motors must be rated for that duty or they fail prematurely. Commercial installations typically require safety edges, photoelectric beams and accessible emergency stops, all of which must be functional before a door is returned to service. Service intervals are set by cycle count rather than by calendar, with high-use doors requiring servicing every three to six months. Fire-rated and high-wind-rated shutters are available where the building classification or exposure requires them. Doormec supplies, installs, services and repairs commercial garage doors and roller shutters across the Illawarra, including the Unanderra and Port Kembla industrial precincts, with 24-hour emergency callout on 0490 774 111.
Suits
Best for
- Workshops, warehouses and loading docks with high daily cycle counts
- Retail and light industrial premises needing reliable overnight security
- Strata and shared residential buildings, where residential openers fail early
- Exposed sites needing wind-rated shutter specification
Trade-offs
Worth knowing
- Duty cycle determines the specification more than opening size does
- Safety edges and beams are not optional extras on commercial doors
- Scheduled servicing outside operating hours avoids disrupting trade
- Repeated failures of the same component usually mean the original specification was wrong
Answers
Commercial Garage Doors & Roller Shutters questions
Why does my commercial roller shutter motor keep failing?
Nearly always because it is under-specified for the actual duty. A motor rated for residential use on a door doing forty cycles a day is running far outside its design envelope and will keep failing no matter how many times it is replaced. The fix is a correctly rated commercial unit, which costs more once and then stops costing you.
Do commercial garage doors need safety edges?
Where people work around the door, yes, and they are a standard requirement on powered commercial doors. A safety edge is a pressure-sensitive strip along the bottom of the curtain that reverses the door on contact, and it works where a photoelectric beam alone would not. If yours has failed, the door should not be used until it is repaired.
Can you service our doors outside trading hours?
Yes, and for most commercial customers that is the sensible arrangement. Scheduled servicing outside operating hours means no disruption to loading or trading, and we provide a documented report after each visit for your compliance records.
