You've picked your building size, your roof style, and your color. Then the configurator asks about frame-outs and you stop cold. Most first-time buyers do.
Frame-outs show up during the ordering process without much explanation, and missing them entirely is one of the most common mistakes we see. Know what they are before you finalize your order, and you'll save real money and real headaches down the road.

Key Highlights
A frame-out is a reinforced opening built into your building's steel wall frame to accept a door, window, vent, or other insert.
Standard end wall openings (your main garage door, for example) are base frame openings, not frame-outs. Frame-outs are the additional openings beyond that.
You can add frame-outs for walk doors, windows, side wall roll-up doors, and custom equipment or ventilation openings.
Frame-out cost scales with the size and location of the opening. Side wall openings require more reinforcement than end wall additions.
Planning your frame-outs before you order matters. Adding or repositioning one after installation is a field modification job. It's doable but far more expensive.
We deliver and install your complete building with frame-outs already engineered in. Call 888-486-6913 to talk through your layout before you design.
What Is a Frame-Out on a Metal Building?
Picture your building's walls as one continuous run of steel panels. By default, the panels cover everything except the main opening on the end wall. A frame-out is what happens when you need an opening somewhere else.
We build additional steel framing members around the cutout, which keeps the wall structurally sound even where the panel is removed. The opening gets a header across the top, vertical jambs down each side, and a sill or base plate at the bottom depending on the type. Without that framing, you're cutting through structural steel with no support on the edges, and that creates a weak point in the wall.
How Frame-Outs Differ from Your Main Opening
Every metal building has at least one base opening on the end wall. That's where the big roll-up door typically goes. The structural frame is designed around that opening from the start, so nothing extra is needed.
A frame-out is the add-on version of that process. Walk door on the side wall? Frame-out. Window on the back wall? Frame-out. Side wall roll-up for a second equipment entry? Frame-out. Same concept, just applied to any opening outside the base frame design.
Where Frame-Outs Can Go
The most common locations:
Side walls (left or right): the most frequently requested location, especially for walk doors and secondary roll-up access
Back end wall: additional openings beyond the base opening, or the primary opening if your building faces the other direction
Front end wall: secondary doors or windows alongside the main entry
Side wall frame-outs take the most engineering because the horizontal girts that span the wall get cut and reinforced. End wall frame-outs are structurally simpler. Both need to be ordered upfront.
Types of Frame-Outs You Can Order
Walk-in Door Frame-Outs
The most ordered frame-out by a wide margin. Standard walk-in doors are 36 inches wide by 80 inches tall, and the frame-out is sized to match. These go on side walls, back walls, or anywhere you need a person-entry point separate from the main end wall opening.
Roll-up Garage Door Frame-Outs
Farmers order these regularly. One main roll-up for equipment and a walk-in door on the side for daily foot traffic. No reason to roll up a 12-foot overhead door every time you need to grab a tool from the workbench, after all.
For enclosed layouts with large access doors, walk-in entries, and workspace storage, see our metal garages with roll-up doors and walk-in entries.
Window Frame-Outs
Window frame-outs come in a range of sizes. Single windows, double windows, vent panels, and more. The frame-out is just the opening with its steel reinforcement. What goes into it is a separate decision.
Workshops and offices inside metal buildings usually need 3 to 5 window frame-outs for usable natural light. A 40x60 building with no windows works, but it's not a comfortable place to spend a full workday.
Side Wall Garage Door Frame-Outs
Roll-up doors don't have to sit on the end walls. If your site layout puts the vehicle approach on the side, or if you need drive-through access from front to back, a side wall roll-up frame-out handles that.
These are larger frame-outs and they require more reinforcement because you're interrupting a bigger section of the wall. Pin down the opening size early. A 10x10 frame-out and a 14x14 frame-out are very different engineering problems.
Product example: See this 18x25 A-Frame Utility Carport with side frame-outs if you want a real product layout with framed side access.
Custom Frame-Outs for Ventilation and Equipment
Sometimes the opening isn't for a door or window at all. HVAC units, exhaust fans, industrial vents, and equipment pass-throughs all need frame-outs sized to the specific unit going in.
When Do You Actually Need a Frame-Out?
Side Wall Access
This is reason number one. Your standard building entry is on the end wall. If you want a second way in from the side, a walk door frame-out is the answer. Site layout often drives this. The driveway might approach from the side, or the end wall might face a fence line that can't easily be accessed daily.
Light, Airflow, and Ventilation
A building you plan to actually work in needs both. Window frame-outs bring in natural light. Vent and exhaust frame-outs pull out fumes, heat, and moisture. If you're welding, painting, running combustion equipment, or just spending serious hours in the space, plan ventilation frame-outs the same way you'd plan them in any other workspace.
Equipment Access from Multiple Directions
Agricultural and commercial buyers often need equipment to enter from more than one wall. One roll-up on the front end, one on the back end, and you have a full drive-through. Side wall roll-up frame-outs let you bring equipment in from a different approach angle entirely. That setup gets planned and ordered from the start.

What Frame-Outs Cost and What Affects the Price
Frame-outs are line items on your building quote. Each one adds to the total, and the price scales with a few things.
Opening size is the biggest factor. A 3x7 walk door frame-out is a small addition. A 14x14 side wall roll-up frame-out is significantly more, both in materials and in the engineering it requires.
Wall location matters too. Side wall frame-outs involve cutting and reinforcing the horizontal girts that span between frame columns. That's more work than adding a secondary opening to an end wall. The complexity gets reflected in the price.
Number of frame-outs adds up linearly. A building with 6 window frame-outs, 2 walk door frame-outs, and a side wall roll-up costs more to produce than the same building without them. That's expected. It's also far cheaper than ordering a bare building and having a contractor modify it in the field after delivery.
Whether a door or window is included or you're ordering the bare opening also changes the number. Some buyers supply their own doors and windows. Others order them as part of the package.

What to Plan Before You Order
Walk Your Site First
Where will you enter the building every day? Where will you bring equipment in from? Which wall faces the driveway and which faces the field or property line? Answer those questions before you finalize your configuration.
Moving a frame-out after installation is possible but expensive. The panels get cut, the framing gets added, and the opening gets sealed back up around the new frame. That's several times the cost of ordering it correctly from the start. A 10-minute site walkthrough before you order prevents that entirely.
Measure for Equipment-Specific Openings
If you're ordering a frame-out for a specific HVAC unit or exhaust fan, get the manufacturer's rough opening requirement before you call or configure. Don't estimate. Generic walk door and window frame-outs have standard sizes. Equipment openings do not.
And if you're sizing a roll-up door for equipment access, think about the widest and tallest thing you'll realistically be pulling through. Add clearance. A 10-foot-wide combine header or a flatbed trailer loaded with supplies is a lot closer to the frame edge than most buyers expect the first time through.

Frequently Asked Questions
Q: What is a frame-out on a metal building?
A frame-out is a reinforced opening built into the building's steel wall frame to accept a door, window, exhaust vent, or other insert.
Q: Can I add a frame-out after my metal building is already installed?
Yes, but it costs more and takes more work than ordering it upfront. Structural changes after installation can also affect your metal building warranty coverage, especially if the modification is not performed by Get Carports.
Q: Do frame-outs cost extra?
Yes. Each frame-out is an individual add-on to your building price. The cost depends on the size of the opening and where it's located on the building.
Q: How many frame-outs can I add to one building?
There's no fixed limit. Your building's structural design adjusts based on the number, size, and location of the openings. More frame-outs in a single wall section require more reinforcement, which the engineering handles automatically when configured properly.
Q: Do frame-outs come with doors and windows included?
Both options are available. You can order a frame-out as a bare opening and install your own door or window, or order the door and window as part of the package. We'll walk you through both when you configure your building.
Q: What's the difference between a frame-out and a rough opening?
Same thing, different terminology. Rough opening is the standard construction term. Frame-out is how it's commonly called in the metal building industry. Both refer to the reinforced structural cutout in the wall designed to accept a door, window, or other insert.
Q: Does adding a frame-out affect my building's wind or snow load rating?
Every opening affects the surrounding wall structure, which is exactly why we frame the opening properly. The framing members maintain the wall's load-bearing capacity around the cutout. If you're in a high-wind zone or a heavy-snow region, communicate that when you order so the engineering accounts for your local conditions correctly. For more detail, read our vertical roof, gauge, and wind rating guide or review the International Building Code for broader code context.
Conclusion
Frame-outs are one of the details that seem minor right up until you've finished a building without them and realize you have no side wall entry, no natural light, and no way to ventilate the space you're working in every day. Plan them before you order. Know where you need access, know your dimensions, and build the openings in from the start.
