How To Install A Metal Carport

How To Install A Metal Carport – A Step-By-Step Guide

Has your storage outgrown your garage space? If so, a metal carport is an investment-worthy option. A carport can protect your valuables like the car, ATV, boat, farm tractor, and so on from the elements and provide shelter for outdoor parties and recreation. And being available at such competitive prices at Steel and Studs makes perfect sense to invest in one. But the big question is how to install a metal carport?

But before this big question comes to another question. Which metal carport type to install? Steel and Studs provides a variety of do-it-yourself metal carport kits.

So, before learning how to build a metal carport, let’s first see the various types of kits available.

Metal Carport Kits

Our metal carport kits are completely customizable. They can match the color of the roof to your building’s exterior, forget the thickness of the steel frame customized to your requirements.

There are three distinct types of metal carports kits depending on the type of roof your weather demands.

  1. Standard Horizontal Roof Style – The standard horizontal roof is the most cost-effective and practical choice. It might not have the bells and whistles of the other two roofs but protects your valuables from sun, rain, and snow.
  2. A-Frame Horizontal Roof Style – They are a little pricier than the horizontal roof style but are more stylish too. Also known as the boxed evade style, its most interesting detail is that it has sheet panels running from the sides for added protection.

  3. A-Frame Vertical Roof Style – It is the most expensive option but comes with additional ridge caps that provide a lot of stability. These are especially useful for those living in harsh conditions.

Whenever you buy from us, we not only provide free on-time delivery across the US but also help you get permits from your respective city or county regulations. We also ensure that our structure meets the local development standards.

Electric Wires

If you want to add lights or other charging points to your steel carport, you must do the required electric wiring. It is suggested to plan the wiring before starting the carport building. You can consult an electrician for the same.

Anchors Bolts

Different anchor types are used for various foundations. Mobile home anchors are primarily used while using a dirt foundation. They are fixed on the bare surface without any foundation. However, you need to level the surface for a good hold. At the same time, concrete anchors are used where concrete footings are made.

Base Rails & Trim

Base Rails form the building footprint and tie your metal structure together. Good quality base rails are made up of galvanized steel. In addition to base rails, bracing both U-channel and Hat channel is available. This extra bracing provides support and stability if you live in an area with a harsh climate like high winds. Also, trims finish up the structure. They are made available in the same color as the panels so that your carport looks as good as it is strong.

Bows And Trusses

Bows and trusses are basically the skeletons of your metal structure’s roof. Their crucial role is to give strength and stability to your garage.

Depending on the type of roofs available, the different types of bows and trusses come. The standard bow for horizontal roofs and A-frame bow for boxed eave horizontal and vertical roofs.

Doors & Windows

If you plan to cover the sides of your steel carport, doors and windows are a must and are available as an add-on to the carport materials.

Remember to use headers when installing doors and windows to support the stresses of opening and closing doors and windows.


Panels are metal sheets that cover the structure’s roof and sometimes the sides too.

How are Metal Carports Anchored to the Ground?

Before you start anchoring metal carports or even prepping the ground, you need to take care of the below steps. These will ensure a hassle-free metal carport building later on!

  • Check with your local city or county planning departments whether you need a permit to build a metal building on your land. Don’t worry. Your very own Steel and Studs experts will assist you in the feat.
  • If you need water or electricity at your metal carport, ask a plumber or electrician to inspect the site before laying the foundation. Most contractors and even you would prefer it that way!
  • Call 811 to mark underground buried gas, electric, or water pipelines.

Metal Carports Anchored to the Ground

1. Level The Site Before Carport Installation

The first step here is to clear any debris or vegetation from the site. And then level the ground properly.

Proper leveling will ensure that the carport structure stays balanced even in high winds and other harsh conditions.

Also, the leveling required depends on the types of foundation– dirt, gravel, concrete, and asphalt.

Lastly, the foundation you choose and the anchors used to secure that foundation to the ground will make all the difference when rains pour and hailstorms strike.

2. Carport With Dirt Foundation.

A dirt foundation demands maximum leveling and clearing of the ground and the space around the site.

You can use mobile home anchors to fix the metal structure to the ground.

However, a dirt foundation is less costly; you may have to deal with standing water and muck as the rain eventually erodes the surrounding soil.

3. Carport With Gravel Foundation.

A gravel foundation too requires much leveling and clearing before you dump stone over the site. Gravel is another cost-effective solution and gives you a slightly more stable foundation for your metal building than soil-based.

However, gravel stone moves with time, so you may have to invest in re-leveling with time.

4. Carport With Concrete Foundation:

Concrete slabs are your best bet to keep your storage safe from the elements. However, you need to hire a concrete professional to pour one.

But be vary of poor quality slabs, redoing them is not an easy alternative.

Also, keep the dimensions of the length of the roof and base in mind while constructing the concrete slab.The building footprint on the slab will measure one foot shorter than the roof length.

Finally, ensure no likelihood of seepage of water under the base rails.

5. Carport With Asphalt Foundation.

An asphalt foundation is constructed on similar lines as concrete. Just that asphalt is cheaper than concrete.

Asphalt foundation can last you years but may need sealing as the years pass as it will get deteriorated due to the elements.

How To Prep For Footings For Metal Carport Kits?

Here is the process of prepping for footings:

  • The first task in laying footings is to mark the centers for each footing.
  • Next, take care the post you want to lay in a footing should be at a maximum of 4′ from the edges.
  • Ensure that your lines are correctly squared. This ensures the footings and posts will go at their exact places.
  • Further, secure your footings by laying string lines to help align the installation of the post. The lines should be applied at a distance of 4″ from the posts and not right onto the posts so that the line is still visible for checking even when the posts have been straightened up.
  • Lastly, mark your post at the depth you want to install them at. This depends on the type of footing you need to use.

Pro Tip: The choice of footing depends on your state and city laws. Therefore, always check with a local engineer before placing your footings. The width, depth, and type of footings will vary depending on your state’s building codes and your carport type.

Here is a step-by-step process:

  • Use a gas-powered auger to dig a deep enough hole, at least 30 inches deep and 10 inches wide, depending on your carport type and local regulations.
  • If you do not have access to an auger, give it a shot with your hands. However, a simple shovel won’t cut it as the hole goes deep.
  • As soon as your holes are dug, start filling them with ACI-specified concrete and keep your post anchors handy.
  • Mostly you will need a 10 – 12 ½ inch galvanized steel anchor for your footings. And be ready with a sledgehammer. You might need a whack or two to push it down if the concrete is stiff.
  • Once you have placed the anchor bolt down far enough, put your post on the top and finish it with a washer and nut.
  • After fixing it is time to adjust it in the right place. To do so, restring the string line and measure it to the center of the anchor.
  • After the anchors are done, final adjustments can be made by sliding them into their adjustable mounting plate to get them exactly where you need them to be.

How Do You Install a Spread Footing for a Steel Carport Kit?

Here is a step-by-step process:

  • Use a spade to excavate the area. You can dig a 2′ wide and 2′ deep hole or as specified by your local regulations.
  • After the excavation, you need to insert a rebar base of size depending on your footings specifications.
  • Next, fill the fill with concrete upto 1′, place a 10″ mold over it,and fill it with ACI-specified concrete.
  • Now, use a 10 – 12 ½ inch galvanized steel anchor for the footings and push it down the concrete utilizing a sledgehammer.
  • Finally, place the post on the top and finish the task with a washer and nut.
  • Measure the alignment of footings with the help of the string line.
  • You can also use a scrap post of the right length to measure the distance from the string line with ease.
  • After the anchors are done, make final adjustments by sliding them into their adjustable mounting plate to bring them in their exact positions.

How to Install A Carport Canopy?

Let’s follow the process step-by-step:

Step 1: Before starting with the assembly, stack the peak tubes on top of each other and line up the ends.

Step 2: Now mark a line 17 1/8″ from one end if your carport is 10′, 12′, 18′, 24′, or 30′ wide. Or mark the same line at 3 5/8″ from one end if your carport is 14′ or 20′ wide.

Step 3: Next, start assembling the roof/wall structure by joining the peak bends to rafters, rafters to side posts, and side posts to height extensions (If needed).

Pro Tip: Driving in two stakes at the bottom and two stakes at the top helps you give accurate dimensions to the structure.(Keep in mind the outer dimensions of the carport)

Step 4: Now that the structure is in place, drill in #12 hex head self-drilling screws at all joints. 4 screws on each side for the peak to rafter joint and side post to rafter joint. And two screws each for the side post and height extension joint.


Use the first assembly as a template and keep stacking the rest of the roof/wall assemblies on top of the previous ones so that you know they all fall in a line. Also, try to keep all the joints equal.

How To Install Truss Bracing?

How To Install Truss Bracing steelandstuds
Guide To Install Truss Bracing

A carport doesn’t always need truss bracing. Truss bracing is done to provide strength and stability to the steel building. Thus, if your county experiences a lot of high winds and snow, brace up because it is time for truss bracing.

However, as a general guideline, 10′, 12′, and 14′ wide carports do not require truss braces. While 6′, 18′, and 20′ carports may need truss braces. But large steel structures like 24′ and 30′ wide carports require bracing.

There are two types of truss bracing:

  1. Collar Tie With Vertical
  2. Collar Tie With Web Braces

For the scope of this article, we will discuss only collar ties with vertical.

Note: Bracing is done on all inside frame sections but not on the two end frames.

Here is the step-by-step process of installing a collar tie with vertical:

  • Step 1: Collar ties comprise three parts- one center tie and two end ties. Attach the end ties to the center tie with six #12 self-drilling screws.
  • Step 2: Install collar tie brackets on both ends of the collar tie vertical.
  • Step 3: To install the vertical to the roof/wall frame, take equal measurements from side to side. Mark the ends and place the vertical carefully. Fasten these collar tie brackets to the rafters with six self-drilling screws on each side.

How To Install Roof/Wall Sections To Base Rails?

This part of carport installation requires at least two people. You can also use a ladder to help you give support for raising the sections into the base rails.

Start by placing the first section, the one with no truss bracing. Once the section is placed inside the base rail, fasten it with two #12 self-drilling screws on each side. Repeat the task with the rest of the sections as well.

How To Install A Metal Carport Roof?

How To Install Roof/Wall Sections To Base Rails steelandstud
Roof/Wall Sections To Base Rails

Follow the below steps closely to install a carport roof:

Step 1: Installing Panel 1

Take a pencil and mark the overhang on the bottom of the panel. This line will help you place the panels in perfect alignment.

Pro Tip: Install the first panel on the lower side of the carport to ensure proper drainage of rainwater.

Do you remember putting a line at 17 1/8″ or 3 5/8″ from the end while assembling the roof/wall sections?

This is the same line that will guide you to place your first panel.

Once the panel is appropriately placed, clamp the panel before drilling screws.

Next, drill your first #12 x 1″ self-drilling screw with a rubber washer 1″ above the major ribs. Don’t install screws on the edge ribs because the adjacent panels will slide onto them. Similarly, screw the second frame as well.

Do not screw the third section because another panel will slide over this first panel there.

Step 2: Installing Panel 2

Let the second panel overlap the first panel by 2″.

Taking care of the overhang and other measurements, screw in the second panel as well.

Continue paneling until the entire roof has been assembled.

How To Install A Trim On A Metal Carport?

Our structure is ready, but we need to apply a vinyl edge trim to give it a perfect finish.

We need to install the trim on the front, side, and back edges of the metal paneling.

You can start at one of the gable ends, work up your way to the peak, and then down to another gable end. Use your tin snips to cut off the trims at the ends. Repeat the process for both the back and front edges.

Also, apply the trim to the side edges. Lastly, use a small hammer to fit the trim over the major ribs.

With this last effort, your metal carport installation process is complete! Voila!
