The Amarr 2400 series is a heavy duty steel sectional commercial door in 24 gauge steel, 2 inches thick, and it takes the widest standard opening of Amarr's three commercial series, up to 30 ft 2 in wide and 26 ft 1 in tall. It comes as the 2402 (single layer, no insulation), the 2412 (two layer) and the 2422 (three layer), with the insulated versions at R 7.0. We supply and install it across Palm Beach County, from West Palm Beach, Lake Worth Beach and North Palm Beach to Wellington, and it is quoted after we measure the opening, with the wind load option specified at order and the Florida Product Approval on the permit.
The 2400 is the door most commercial openings in Palm Beach County end up with, and the reason is the size range rather than the steel. The 2500 series stops at 20 ft 2 in wide, so any bay wider than that is already out of its reach, and the 2000 series is 20 gauge extra heavy duty steel that most warehouses, service bays and storage buildings do not need. The 2400 sits between them: heavy duty 24 gauge steel, the same deep ribbed smooth panel as its two siblings, and a standard width that runs all the way to 30 ft 2 in.
Most of the searches that reach us for this door are a model number and a town, "amarr 2400 wellington" or "2400 north palm", which usually means a spec has already been written by an architect, a property manager or the last contractor, and what is wanted is somebody local who will measure, order the right construction with the wind load package, pull the permit and hang it. That is the job we do. We are an independent installer, not an Amarr dealer, and we say so on every quote.
The one decision the model number does not make for you is the construction. The last two digits carry it: 02 is single layer, 12 is two layer, 22 is three layer. That choice is about how much the door gets knocked, how much heat the building can take through it, and how quiet it needs to be, and it is covered below.
2402, 2412 or 2422: choosing the construction
Bare 24 gauge steel with no insulation. The lowest cost way into the 2400 series and the right door for an unconditioned building: a boat or equipment store, a covered bay that is open on another side anyway, a barn. The trade off is stiffness. A single skin section dents more easily at the bottom, where forklifts, trailers and carts meet it.
Steel with vinyl-coated polystyrene insulation behind it, R 7.0. The common middle choice in Palm Beach County: stiffer than the 2402, quieter in use, and it stops a west facing bay from turning into a radiator in the afternoon, which matters as soon as the space behind the door is air conditioned.
Steel on both faces with the insulation between, also R 7.0. The finished interior face is the reason to choose it: it looks right in a showroom or a customer facing service bay, it cleans easily, and a steel inside face takes knocks from the inside that a vinyl back would not.

When the 2400 is the right door, and when it is not
We specify it for
- Openings wider than 20 ft 2 in, which the 2500 series cannot take
- Warehouse, distribution and light industrial bays that cycle through the working day
- Service and repair bays where an insulated door keeps an air conditioned shop workable
- Marina, boat and equipment storage buildings where a wide opening matters more than heavy gauge steel
- Equestrian and farm buildings in Wellington and the western county that take trailers
Choose something else when
- An opening that takes real abuse every day from forklifts or trucks, where the 20 gauge 2000 series is worth the extra
- A small bay under 20 ft wide on a tight budget, where the 2500 series does the same job for less
- A house. The 2400 is a commercial door, and a residential opening is better served by a residential wind rated door
Wind load in Palm Beach County
Palm Beach County is outside the High Velocity Hurricane Zone, but the design wind pressure is still high and it rises as you get closer to the coast, so a door on a building in Lake Worth Beach or North Palm Beach is working against more than the same door out in Wellington. A replacement commercial door needs a Florida Product Approval that covers the design pressure at the address, and a building permit pulled by a licensed contractor.
Amarr lists wind load as an option on the 2400 series, not the default, and that is the single thing most worth getting right. It has to be specified when the door is ordered, because the approval covers the assembly that was tested, with its reinforcement and its track, not a standard door with parts added later. We confirm the current approval for the size and pressure before we quote, and it goes on the permit. For a building in Broward or Miami-Dade, inside the HVHZ, the requirement is a Miami-Dade NOA instead, and we confirm one exists for the size before anything is ordered.
Where we install the 2400 in Palm Beach County
Across the county, and the permit goes to whichever building department holds the address. West Palm Beach, Lake Worth Beach, Riviera Beach, North Palm Beach, Palm Beach Gardens, Jupiter and Wellington each have their own. The large unincorporated areas, including the Lake Worth addresses west of the city and much of the western county, go through Palm Beach County, and we check which one applies before the quote so the timeline is real.
Close to the water, salt air is the other local factor. On a building within a few miles of the Intracoastal, we specify galvanized or stainless hardware where it is offered and look at the bottom bracket and cable on the old door, because that is usually what failed first.

How a 2400 quote works
- We measure the opening. Width, height, headroom above the door, sideroom each side and backroom behind it. The track configuration and the spring follow from those numbers, and a quote without them is a guess.
- We confirm the construction and the wind load. Single, two or three layer, and the approval that covers the design pressure at your address. If the building is inside the HVHZ we confirm the NOA exists for the size.
- You get one written price. Door, wind load package, springs sized to the finished door weight, operator if you want one, removal of the old door, permit and installation. No list price and no surprises after the order.
- We order, permit and install. The permit is pulled while the door is in production, and it is inspected after installation as the department requires.
Amarr 2400 questions
How much does an Amarr 2400 commercial door cost?
It depends on the opening, the construction and the wind load package, which is why we quote after measuring rather than from a list. A 2402 costs less than a 2412, which costs less than a 2422 of the same size, and the wind load option adds to all three. The quote you get is one written number covering the door, the wind load package, springs sized to the finished door, removal of the old door, the permit and installation.
What is the difference between the Amarr 2400 and the 2500?
Duty rating and size. The 2400 is heavy duty 24 gauge steel and takes openings up to 30 ft 2 in wide and 26 ft 1 in tall. The 2500 is medium duty in nominal 24 gauge, aimed at budget sensitive work, and stops at 20 ft 2 in wide and 16 ft 1 in tall. Both are 2 inches thick, both come in single, two and three layer versions, and both have an R 7.0 insulated option and a 10 year limited warranty. If the opening is wider than 20 ft 2 in, it is a 2400 or a 2000 regardless of budget.
Is the Amarr 2400 rated for hurricanes in Florida?
It can be, when it is ordered with the wind load option. Wind load is an option on the 2400 series, not the default, and in Palm Beach County a replacement commercial door needs a Florida Product Approval covering the design pressure at the address. The option has to be specified at order, because the approval covers the tested assembly, not a standard door upgraded afterwards.
Do you install the Amarr 2400 in Wellington, Lake Worth and North Palm Beach?
Yes, and across the rest of Palm Beach County: West Palm Beach, Riviera Beach, Palm Beach Gardens, Jupiter, Boynton Beach, Delray Beach and Boca Raton, plus the unincorporated county. We check which building department holds the address before we quote, because the permit goes there.
Should I get the 2402, the 2412 or the 2422?
The 2402 for a building that is not air conditioned and where the door does not take knocks. The 2412 for most working bays, because the insulation at R 7.0 makes it stiffer and quieter and keeps afternoon heat out of a conditioned space. The 2422 when the inside face will be seen by customers or needs to take knocks from the inside, because it is steel on both faces.
Can you repair an existing Amarr 2400 door rather than replace it?
Usually. Springs, cables, rollers, hinges, bottom seals and operators are all repairable, and a single damaged section can often be replaced when the same series and construction is still made. We look at the door and tell you plainly whether repair or replacement is the better money, in writing, before any work.
