What the door is

High speed doors, described plainly.

A tall rolling steel door on a metal building

A high speed door is built around one idea: the less time an opening spends open, the less it costs you. They move quickly, cycle constantly, and are usually chosen to hold a temperature, keep dust or contamination on one side, or keep traffic moving through a busy internal opening.

That speed and that cycle count change what wears. These are doors specified around traffic first and appearance last, with their own controls, sensing and activation — and on many sites they sit behind or alongside a conventional sectional or rolling steel door that does the security job at the end of the day.

Because the type covers a wide range of equipment, the honest first step is a technician looking at what you actually have. We will tell you plainly what we can take on and what belongs with the equipment’s own specialist, rather than quote around it.

Where it is usually working

Cold and temperature-controlled openings Where every second the opening is open has a cost on the meter.
Clean, dust-controlled and paint areas Where the door is separating two environments rather than inside from outside.
Busy internal traffic openings Between production and warehouse, where forklifts pass constantly.
Car wash and vehicle throughput bays High cycle counts, wet conditions, and doors that cannot be the bottleneck.
Openings paired with a security door A fast door for the working day and a conventional door for the night.

What actually fails

The six things we are called out for.

Described the way a facilities manager sees them rather than by part number. If what your door is doing is not on this list, call and describe it — a person answers 24/7.

Cycle wear, everywhere At these cycle counts every moving part reaches its service life sooner. That is the defining characteristic of the type.
Impact and misalignment Forklift contact, and doors that no longer run true in their guides.
Activation and sensing Motion sensors, pull cords and photo-eyes — a door that will not trigger, or triggers when it should not.

Controls and limits Boards, encoders and travel settings on equipment that runs all day.
Seals at the perimeter The whole point of the door on a temperature-controlled opening.
The conventional door beside it Frequently the neglected one, and frequently the one that fails when the fast door is out of action.

Before you call

Five things worth having to hand.

Start with what you have. Each detail narrows what the technician needs to check.

The maker’s plate Find the label or serial plate. Its position varies: a side column, the operator or the control box.
Opening and curtain Width, height, headroom and side room, and whether the curtain is fabric, vinyl, rubber or slats.
What opens it, what guards it Push button, pull cord or motion sensor to open; photo-eyes, reversing edge or light curtain to guard.

Cycles, roughly A daily estimate of cycles, or a logbook count, shows where the door stands against its maker’s intervals.
Faults and conditions Any fault message exactly as shown, and whether wind, cold or dust affects the door.

Safety rules

What the rules ask of a fast door.

Mostly about not trapping anyone, and knowing protection still works.

UL 325 The safety standard for door operators, aimed at keeping a moving door from trapping anyone. DASMA says high performance doors may or may not need it, depending on specification, insurance, local ordinance or the owner, so ask the maker.
Monitored protection For commercial operators, UL says a door closing on a timer or remote needs a floor-level photo-eye or edge that the operator keeps checking. If the check fails, the door closes only while a button is held, a sign a protection device is not working.

Photo-eye, edge, break-away A photo-eye signals a stop or reversal when its beam is blocked; a sensing edge does so on contact. Break-away, on some fabric doors, releases the curtain from its guides in a forklift hit.

Upkeep

How often a fast door needs attention.

DASMA has makers supply the schedule. These are examples; yours governs.

Daily Rytec’s Spiral manual asks for a visual check of panels, columns, photo-eye lenses and the reversing edge, then four or five full cycles.
Monthly For doors above 50,000 cycles a year (about a thousand a week), Hörmann’s HD rubber door manual lists monthly checks of the reversing edge, photo-eye, limits, fasteners and curtain tracking.

Quarterly Rytec recommends inspecting its high performance doors quarterly; its Spiral manual has the disconnect locked and tagged for electrical and head-assembly checks.
By cycles Albany’s RapidRoll manual sets some intervals in time or cycles, such as half-yearly or 50,000 cycles. Hörmann’s lower-cycle doors get annual servicing plus the tests local rules require.

What a visit involves

The estimate is the document you route.

A technician looks at the opening with you and writes the price before anything starts. Nothing begins until it comes back approved, and the invoice matches the number you approved.

Tell us what you have, in whatever words you have A photograph of the opening and of the controller label is worth more than a model number you are not sure about.
We say what is ours and what is not You get a straight answer about scope before a number, not after it.
The opening keeps working where it can If the fast door is down, the conventional door beside it is usually what keeps the site running — so it can be looked at in the same visit.
Repairs scheduled around operating hours Tell dispatch when the opening can be taken out of service. A person answers 24/7.
5-Year Warranty on All Parts & Labor. Five years on parts and labor, every repair and every install.

Describe it however makes sense to you

Tell us which opening, and when it has to run.

Tell us about the opening, the door and the traffic it has to carry. A technician measures on site, and nothing is ordered until the written estimate comes back approved.

No spec sheet needed. The opening and how the dock runs are enough to start.
The written estimate is free. Nothing owed if you pass.
Nothing is ordered until the estimate comes back approved.

Questions people ask

Straight answers.

Do you work on high speed doors?

Tell us what is on site and a technician looks at it. High speed covers a wide range of equipment, so we give you a straight answer about what we can take on and what belongs with the equipment’s own specialist before any number is quoted.

Our fast door is down and the bay is open to the yard

Say so on the call. An opening that cannot be secured changes how a job is handled.

Can you service the sectional door next to it?

Yes, and it is usually worth doing in the same visit — the conventional door is the one keeping the opening usable while the fast door is out.

High speed or high performance: what differs?

DASMA calls a powered non-residential door high performance if it generally runs 100 or more cycles a day or opens at 20 inches a second or more. Within that, high speed means opening at 32 inches a second or more.

How do we test the safety devices?

Follow your manual’s test. Generally a blocked beam should stop or reverse a closing door, and tapping the reversing edge should send it back up. Keep clear of the door’s path; stop using a door that fails.

Why does it keep reversing?

It may be a safety device reacting: a blocked or misaligned photo-eye, a dirty lens, or a tripped reversing edge awaiting reset. One maker’s manual says to clean the lens first, then align or replace the eye.

Should we lubricate a fast door ourselves?

Only as the manual says. One maker says tracks may need grease more often than every six months; another says its door must not be lubricated, because lubricant attracts dirt and can make the panel bind.

Can a fast door run in high wind?

Ask the maker for its operational wind load. DASMA notes that running a door on momentary controls in wind above that load can damage it, and says to contact the maker for doors in windy conditions.

Are you insured?

Yes. Insured & Bonded, with Background-Checked Technicians.

How does approval work on a PO?

The written estimate is the document you route. Nothing starts until it comes back approved, and the number on the invoice is the number you approved.

Do you charge to come out?

No. We look at the door with you and give you a written estimate. You approve it before any work starts, and there is no charge if you decline.

What does the warranty cover?

Five years on parts and labor, every repair and every install. The scope is on the estimate you approve and on the invoice.
