"Roll-up door" is a description, not a product. It is what most people call anything that coils above an opening, and it covers at least four different products that are built to different standards, carry different price bands, and are wrong for each other's jobs.

That matters because the most expensive mistake in commercial door work is specifying the right size and the wrong product. A door that is too light for its cycle count fails early. A door that is heavier than the opening needs costs money for no benefit. And a fire-rated opening cannot legally take a non-rated door at all.

This page is the comparison we would walk you through on a site visit.

The four products people call "roll-up doors"

These are not marketing categories. DASMA publishes mutually exclusive ANSI standards for them, which means the standards themselves treat them as different products:

Two things worth pulling out of that table:

The 10,000-cycle figure is a floor, not a target. ANSI/DASMA 203-2020 §11.1.2, DASMA 207-2018 §11.1.2 and DASMA 204-2018 §12.1.2 all require springs to be designed for "a minimum of 10,000 cycles of operation." Commercial practice goes well beyond that: standard service doors are commonly sold at 20,000–50,000 cycles, and high-cycle builds run into the hundreds of thousands. The standards set no upper classification, so "high cycle" is a manufacturer's number, not a code term — ask for it in writing.

Sheet doors and rolling steel doors are not interchangeable. ANSI/DASMA 203-2020 §1.3 expressly excludes rolling sheet doors from its scope. A sheet door on an opening that gets cycled heavily is the single most common specification error we see in self-storage and light industrial buildings, and it is why those doors fail early.

Sizing and headroom

Rolling doors coil into a headplate above the opening, which is the opposite of a sectional door — the sectional door needs ceiling depth, the rolling door needs vertical space above the opening. Neither is universally better; it depends on your building.

What we need to size an opening correctly:

• Clear opening width and height
• Available headroom above the opening, and what the wall above it is made of
• Side room on each side, and how much of it is structural
• Whether the wall is masonry, tilt-up, pre-engineered metal or stud
• What the opening is used for, and — the one people leave out — roughly how many times a day it cycles

Cycle count is the most important number on that list and the least often supplied. A door used twice a day and a door used two hundred times a day can be the same size and need completely different hardware.

Duty and wind

Two specification items that get skipped and then cause problems:

Duty rating. Given as a cycle count. Ask what the springs are rated for and whether the balance of the components matches — a high-cycle spring set on standard-duty hardware moves the failure somewhere else rather than removing it.

Wind load. Houston requires site-specific basic wind speeds under ASCE/SEI 7-2022 rather than a fixed citywide number (Houston Permitting Center CE-1110), and doors must be able to resist the resulting design pressures. ANSI/DASMA 108-2017 is the test standard for structural performance under uniform static air pressure difference, and it covers rolling doors as well as sectional. If a door is supplied without a pressure rating for your site, that is a gap, not a detail.

What drives lead time

Lead time is usually the longest part of a commercial door project, and it is the number facility managers most need and least often get. It varies with:

• Door type and duty — standard sizes move faster than custom
• Finish and colour — special colours add time
• Whether the opening needs a fire rating, which brings labelling and documentation with it
• Operator and controls, if they are not already on site
• Current mill and fabricator backlog

We state lead times on the quote with the date we confirmed them, because a lead time without a date is a guess.

What we ask for before quoting

Send these and you will get a line-item number rather than a range:

• Door count, and opening sizes as width × height
• Door type if known, or a photograph of the existing door
• What the opening is used for and roughly how often it cycles
• Whether the site is occupied, and any access restrictions
• Wall construction at the opening
• For anything with a fire rating: the rating required and where the requirement comes from

You do not need to know the product name. That is our job, and "it's a big grey door that goes up and down a lot" is a perfectly good starting point.

Where each product lives in more detail

• Rolling steel and coiling service doors — the workhorse product, and how to specify it
• Self-storage unit and drive-up doors — the sheet door class, and why it fails the way it does
• Fire-rated overhead doors — ratings, drop testing and what the building owner is responsible for
• Commercial door operators and controls — when the door is fine and the operator is not
• Loading dock doors — dock openings, shelters and the impact problem
• Installation and replacement — how a project actually runs
