Open vs. Partially Enclosed Carports: Choosing Your Panel Layout

People often toss around the word "gauge" when discussing metal buildings, but few stop to consider what it really means. For steel, its gauge is a system of determining how thick it is. The smaller the number, the thicker the material.

What Is Gauge?

Most metal buildings utilize 14-gauge steel for their framing. It’s light, sturdy, and can hold its own in most scenarios. However, some environments with higher wind speeds and snowfall demand thicker 12-gauge framing to carry the load and pass local building requirements.

And while you might not notice much of a difference in performance at first, that beefier framing makes it a lot harder for nature to bend or twist your structure out of shape.

Key Highlights

• 12-gauge = thicker and stronger
• 14-gauge = good for most small to mid-size builds
• Lower gauge = better wind and snow performance
• 12-gauge holds shape longer under stress
• Often comes with a better warranty
• Price bump is small compared to the upgrade in strength

Steel Gauge Chart

Gauge	Inches	Millimeters

10	0.135 in	3.43 mm
12	0.105 in	2.67 mm
14	0.075 in	1.90 mm
16	0.060 in	1.52 mm
18	0.048 in	1.21 mm
20	0.036 in	0.91 mm
22	0.030 in	0.76 mm
24	0.024 in	0.61 mm
26	0.018 in	0.46 mm
28	0.015 in	0.38 mm
30	0.012 in	0.30 mm

How Gauge Impacts Loads

Thicker framing doesn’t just sound tougher. It is tougher. Heavier steel stands up better to snow buildup, hard gusts, and the added stress from longer spans.

Engineers run the numbers for wind and snow loads based on ASCE 7 standards. Using this system, buildings can be rated for anywhere from 115 to 170 mph winds and 20–60 psf snow loads.

The local requirements for wind and snow loads depend on location, open exposure, and roof pitch. For example, a building sitting on a hill or near the coast deals with more pressure than one behind trees.

Upgrading to 12-Gauge Framing

At what point should you consider upgrading?

• High Wind Speeds

If your metal building will sit in an area with high wind speed calculations, you may need to upgrade to thicker framing to prevent swaying or failure.

• Heavy Snow Regions:

If you expect to see your fair share of deep snows this winter, upgrading your framing thickness is a smart move.

• Longer, Bigger Buildings:

Longer spans put more stress on the frame of your pre-engineered metal building.

• Certification Needs

Higher wind or snow ratings often call for thicker 12-gauge.

• Lower Maintenance:

Thicker steel can last longer and require fewer repairs over the course of its life.

Cost and Warranty Changes with Framing Upgrades

You can expect a small price increase when you upgrade from 14-gauge to 12-gauge framing. You pay for thicker steel, heavier anchors, and reinforced braces to match it. Usually, you’re looking at around 10–15% more on the framing side.

However, that extra spend often gets you a longer rust-through warranty, sometimes 25 years instead of 20. The thicker galvanizing takes longer to wear down, especially in damp or coastal areas.

So, while the up-front cost stings a little, you’re getting fewer repairs, less movement, and a frame that won’t quit early. In the long run, it’s usually worth every bit.

Frequently Asked Questions about Framing Gauges for Metal Buildings

Do you have questions about framing gauge, and which thickness is best for you? Below, we’ve answered some of the questions we see on this subject the most:

Is 12-GA stronger than 14-GA?

Answer: Yeah. It’s thicker, heavier, and stiffer under load.

What’s the real thickness difference?

Answer: 12-ga steel is about 0.1046 inches thick, while 14-ga runs around 0.0747 in.

Does 12-GA automatically mean better wind or snow ratings?

Answer: Not by itself. The full design, including anchors, trusses, and layout, plays a role. But thicker framing helps you hit higher numbers.

Does the 20-year rust warranty only cover 12-GA?

Answer: Usually, the heavier gauge gets longer coverage. Some 14-ga options still offer 20 years, but 12-ga often goes a few years beyond that.

For many buyers, choosing a carport isn't simply a matter of deciding on the size or roof style. One of the biggest decisions comes later: whether to leave the structure open or add partial side and end panels. The right layout can make a noticeable difference in how well the building protects vehicles, equipment, livestock feed, or outdoor workspaces from wind, rain, snow, and sun.

There isn't a one-size-fits-all answer. Some properties benefit from the accessibility of an open carport, while others need additional coverage on the sides or ends to handle local weather conditions. This guide explains the differences between open and partially enclosed carports, the most common panel configurations available, and how to choose the layout that best fits your property, climate, and the way you'll use your building.

Key Highlights

• A fully open carport has zero side panels. Add panels to any wall and it becomes partially enclosed.
• Partial enclosure gets measured in linear feet of panel, like a 10-foot enclosure built into a 30-foot wall.
• Gable ends, the triangular wall sections under the roof peak, can close even when both long sides stay open.
• Your prevailing wind direction should decide which side gets panels first.
• Snow piles up against whichever wall is solid, so plan clearance before you order.
• More panel footage adds labor and material to your quote, and it can shift how your county treats the structure for permitting.

Most Carports Land Somewhere Between Open and Enclosed

Most carport searches start as a simple choice: open, or enclosed. We cover that basic decision in our open versus enclosed metal carports guide. Read that first if you haven't settled on a general direction yet.

Almost everyone lands somewhere in between, though. Farmers close the windward wall and leave the rest open for tractor access. A contractor might panel two sides for security and leave one bay open for the truck. For homeowners, closing one long wall against a neighbor's view while keeping the drive-through side clear is common.

The real decision comes down to how much wall to close and which wall to pick, and that depends on how you use the space, which direction your weather comes from, and what you're protecting inside it, all things this guide walks through one at a time.

The Panel Layout Options We Build, From Zero Panels To Fully Closed

Every layout on this list, open or closed, uses the same 14-gauge tubing frame and 29-gauge steel panels. The frame strength stays constant no matter how many walls you close. Panels only add coverage, trim, and weight.

Fully open framing, with panels added later

An open carport is just posts, trusses, and roof panels. No walls anywhere. This is the lowest-cost starting point and the choice most buyers make when shade and rain cover matter more than wind or theft protection. You can always add panels to specific bays later. Ask us about your roof style before you order if you think you'll enclose part of it down the road, since some framing setups make future panels easier to add than others.

Partial side enclosure measured in linear feet

Partial enclosure gets measured in linear feet of panel. A 30-foot carport with a 10-foot enclosure means ten feet of one wall gets paneled, usually paired with a roll-up door, while the other twenty feet of that wall plus the whole opposite wall stay open. That's enough to lock up feed, tools, or a workbench without blocking the drive-through path your equipment uses every day.

Multi-side and fully closed layouts

Close two adjacent sides plus both gable ends and you've built a wind-block on two exposures while keeping one long side and one short side open for access. Close three sides and you're left with a single open bay, functionally similar to a one-car garage without a front wall. Close all four sides and add framed door openings, and you've got what we list as a closed carport. If you're leaning toward full enclosure, our metal garages versus carports comparison covers when a garage door and finished interior make more sense than a paneled carport shell.

Matching Your Layout to How You Actually Use the Carport

Farmers and ranchers moving equipment daily

If a tractor, combine, or livestock trailer goes in and out multiple times a day, an open drive-through side isn't optional. Close the wall that takes the worst of your winter wind, usually the north or west side depending on where you farm, and leave the entry side alone. Hay and feed do better with airflow anyway, so a fully open structure sometimes beats a closed one even when theft isn't a concern.

Contractors staging materials and tools

Job site theft usually starts with tools and copper wire sitting in plain view from the road. Two closed sides with a roll-up door gets you a lockable bay for the expensive stuff, while the open side still lets a truck or trailer pull straight through. Panel the road-facing wall first.

Homeowners storing a vehicle, RV, or boat

A vehicle or RV under an open roof stays dry from above but takes wind-driven rain on the sides during a real storm. Close the wall that faces your prevailing weather and the gable ends, and you've cut most of that exposure while keeping enough open access to back a trailer in without threading a door opening. Boats and RVs with tall profiles usually do better with panels on the sides and gables only. Doors add cost and complexity most owners don't need for something they pull out a few times a season.

Let Wind and Snow Direction Pick Your Enclosed Side

Find your prevailing wind side before you order panels

Every region has a dominant storm direction, and it's rarely a mystery if you've lived on the property through a winter. Check which way your trees lean, which side of the house gets the worst ice buildup, or just ask a neighbor who's farmed the land longer than you have. That's the wall that should get panels first, regardless of which side looks better from the road. Our guide on why metal carports sway in high wind goes deeper on bracing and anchoring if wind is your main concern.

Snow drift builds against whichever side you close

A solid wall stops wind, and stopped wind drops snow right at the base of that wall. Plan for drift depth against any enclosed side, especially in states that see sustained wind during snow events, and keep enough clearance that a roll-up door doesn't end up frozen shut behind a three-foot drift. Our snow and wind load guidance covers how your local ratings factor into the build itself, and it's worth a look alongside your panel decision.

Open Vs. Partially Enclosed Vs. Fully Enclosed at a Glance

Here's how the three main layouts stack up on the factors that actually change day to day.

Factor	Open (no panels)	Partially enclosed	Fully enclosed
Wind and rain protection	Roof only; blowing rain still reaches stored items	Blocks wind and rain from the enclosed side	Blocks wind and rain from all sides
Airflow	Full airflow on every side	Airflow through the open side, low moisture risk	Limited airflow; plan for ventilation
Access	Any side, any time	One side stays a drive-through or walk-in bay	Framed door openings or roll-up doors only
Security	None; contents visible and reachable	Enclosed sides are secure, open side is not	Full; lockable like a garage
Typical labor and material add	Baseline framing only	Moderate; panels and doors on select walls	Highest; panels and doors on all four walls
Best suited for	Shade and quick weather cover for vehicles or equipment	Farm equipment, hay, or work trucks needing wind-block plus airflow	Tools, feed, or anything that can't get wet or blow around
Foundation and framing	Same base framing as any EMB carport	Same base framing, plus door thresholds where panels meet openings	Same base framing, plus thresholds and anchoring at every door

What Changes On Your Quote Once Panels Get Added

More panel footage means more material and labor

Every linear foot of enclosed wall adds panel material, trim, and install labor to your build. Roof style, gauge, and overall footprint usually move your total more than panel layout alone does; our carport cost guide breaks down what drives price the most. Call (208) 572-1441 and we'll price your specific layout instead of guessing from a table.

Panel choice can affect how your county classifies the structure

More enclosure can push a structure toward stricter local review in some counties, since a closed building reads differently to an inspector than three posts and a roof. Permit triggers vary by jurisdiction. We can provide engineer-certified drawings that make the permit conversation faster once you know what your county needs. Confirm requirements with your local building department before you finalize plans.

You've picked your garage size. Maybe you've settled on a roof style too. Then comes a detail plenty of buyers skip past: where the doors actually go. Metal garage door placement needs to happen on paper, weeks before the truck shows up.

Get the roll-up door on the wrong wall and you're backing a trailer through a tight turn every time you use it. Put the walk-in door too close to the roll-up track and it bangs into your truck's mirror.

In this blog, we’ll explore how we plan door layout so your garage works for the way you actually use it, and you can avoid any mishaps along the way.

Key Highlights

• Gable end roll-up doors give you a straight, drive-through path. Side entry doors free up both end walls for shelving or storage.
• Our roll-up doors run from 6x6 up through 14x14 depending on the model, so match the opening to what you're actually parking or hauling.
• Walk-in doors come in a standard 36-inch by 80-inch frame, and they work best a few feet clear of the roll-up door swing.
• Door thresholds should sit on the high side of your pad. Water runs downhill, and a low threshold collects it.
• Every opening gets framed with the same 14-gauge tubing that carries the rest of the building, wide door or narrow.
• Door placement is easier to change before you order than after the steel is cut.
• Call (208) 572-1441 or design your building online before you lock in your layout.

Where Should The Roll-Up Door Go on a Metal Garage?

Most metal garages put the roll-up door on the gable end, the narrow wall where the roofline peaks. That's the traditional layout, and it works for a simple reason. Straight in, straight out. No turning required.

Gable end entry: the straight shot

A gable end door lines up with the length of the building. Back a truck or trailer in, and you've got the full depth of the garage ahead of you, no maneuvering needed once you clear the opening. This layout works best when your driveway or approach comes in straight, without a tight turn near the door.

Side entry: freeing up your gable ends

A side entry garage moves the roll-up door to the long wall instead. We build these regularly, and the appeal is simple: both gable ends stay open for a workbench, shelving, or a second door. The tradeoff is turning radius. You need enough room on your site to swing a vehicle 90 degrees before it lines up with the opening, and a 20x30 side entry garage with two 9x8 roll-up doors, similar to some of our two-car layouts, needs more driveway width than the same building built with a single gable end door instead.

Two roll-up doors: a drive-through layout

Some metal garages use two roll-up doors, one on each gable end, instead of a single opening. That gives you a true pull-through: park a trailer, unhook it, and drive out the other side without backing up. This layout works well for farm equipment, boats, or anyone who hooks and unhooks trailers often. It costs you storage wall space on both ends, so weigh that against how often you'd actually use the pull-through.

Where to put the walk-in door

The walk-in door earns its spot by staying out of the way. Put it too close to the roll-up door and every time that door rolls up, you're stepping around it.

Set your walk-in door far enough from that opening that its swing doesn't clip the roll-up track or a parked vehicle's mirror. Most buyers leave a few feet of clear wall between the two, more if the garage will regularly park a wide truck near that wall.

Match it to how you actually walk in

The walk-in door you'll use most is the one closest to your house, shop, or the path you already walk every day, not the one that looks balanced on a drawing.

A tool run, letting the dog out, grabbing a bag of feed. Those trips happen without pulling a vehicle in first, and they add up to most of your daily traffic through that building. Place the door where that traffic already goes.

How your site changes door placement

Your lot does some of the deciding for you. Grade, wind, and how you approach the building all push door placement in one direction or another.

Grade and drainage: keep water off the sill

Water runs downhill, and a roll-up door sitting at the low point of a sloped pad collects it. Place door openings on the high side of the grade where you can, or make sure the pad extends past the threshold so runoff has somewhere to go besides your garage floor. This matters more on a dirt or gravel base than a poured slab, since a slab can be graded to pitch away from the door during the pour. Check our site preparation guidance before you finalize your pad plan.

Wind exposure and which way the weather comes from

A roll-up door catches wind like a sail when it's up. In open, exposed areas, like much of the plains or coastal flatland, buyers often orient the roll-up door away from the prevailing wind direction so it's not fighting a headwind every time it opens. If you're not sure which way storms typically move across your property, a neighbor who's lived there a while usually knows.

Sizing the roll-up door for what you're parking

The size of your roll-up door decides what can drive through it, so size the opening around your biggest vehicle or piece of equipment, not your smallest. If you haven't locked in a garage size yet, our standard garage sizes guide walks through common dimensions and how they pair with door openings.

Our most common roll-up door sizes line up with what buyers typically park behind them:

Door size	Typical fit	Best for
6' x 6'	Compact car, ATV, riding mower	Single-vehicle garages, workshops
6' x 7'	Small car, motorcycle bay	Utility buildings, side entry setups
8' x 7'	Full-size pickup, SUV	Most single and two-car garages
9' x 8'	Full-size truck with towing mirrors, small tractor	Farm and ranch garages
10' x 8'	Full-size truck, ATV/UTV combo	Two-car and working garages
10' x 10'	Truck with a topper, small equipment	Combination garage and shop buildings
12' x 12'	Tractor, skid steer, small RV	Commercial and ag buildings
14' x 14'	Larger equipment, box truck	Commercial buildings, large equipment storage

If you're between two sizes, size up. A roll-up door that's a few inches too narrow means folding in mirrors every time you pull through, and that gets old fast.

Metal garage door placement mistakes to avoid

A few placement mistakes seem to show up again and again, and most of them are easy to avoid once you know to look for them.

• Putting the roll-up door on the downhill wall of a sloped site, then dealing with water at the threshold every spring.
• Placing the walk-in door where its swing blocks a parked vehicle or a workbench that hasn't been built yet.
• Sizing the roll-up door for the vehicle you own now, not the truck, boat, or trailer you'll own in five years.
• Forgetting to check overhead clearance. A roll-up door needs the header height plus room for the tracks to curve up into the ceiling, not just the door height itself. Our metal building height guide breaks down sidewall height versus usable clearance.
• Choosing side entry without measuring the turning radius your driveway actually allows.

Conclusion

Door placement is one of the last things buyers think about and one of the first things they notice once the building's up. Gable end or side entry, single door or drive-through, the right layout comes down to your site, your driveway, and how you'll actually use the space day to day.
