How To Build a Carport Yourself

The carport is a structure used to protect cars, trucks, boats and other vehicles from snow and rain. There are several types of carports. In terms of material, carports include metal, wood and canvas. No matter what kind of carport, it can protect the car and prolong its life. In addition to being a carport, it can also be used as a storage space or shade structure.

Compared to wood and fabric, most metal carports are made of steel, which is more durable and strong, withstanding wind and rain, unlike wooden carports, which corrode easily. Plus metal carports are low-maintenance than wood.

Building a metal carport yourself requires only steel carport kits, tools, a suitable site, and know-how, which is not as difficult if you have construction experience. This guide will solve your difficulties by introducing the preparation and steps for building a steel carport.

What are the factors to consider before building a carport?

1. Structure size

The first step is determining the size of your desired carport.

The standard carport size is 12ft × 20ft for one vehicle. If you want to park more vehicles or a larger tractor, you will need to consider purchasing double carports or triple carports.

2. Budget

The budget is an important factor in choosing the right type of metal carport.

• For a tight budget: Consider an open-sided carport, it uses less steel material, and no doors or walls, making it easy for cars to enter and exit.
• For an ample budget: The enclosed carport may be a good choice, it includes side panels or doors, which better block the wind and sand, and have better protection performance.

3. Ground

When choosing the ground, it is necessary to avoid power or gas lines for safety. Additionally, the type of ground surface significantly impacts the building of the carport.

Concrete ground: This surface is known to be the most solid, extending the lifespan of the carport. Building on concrete is relatively straightforward without additional ground preparation.

Soil ground: The stability of the soil foundation can be influenced by weather conditions. Therefore, it is crucial to level the ground and lay a layer of gravel before constructing the carport.Building permit.

4. Building codes

Before building a carport, verify local building codes. Typically, you will need to apply for a building permit and submit a construction plan that includes details such as size, location, and other relevant information. If your community has a homeowners association (HOA), you comply with the HOA's standards in addition to the building code.

What materials are needed when building a carport?

1. Carport Structural Parts: The posts are usually made of high-quality steel, which provides excellent strength and durability. They are anchored into the ground to support the weight of the carport structure. The panels are corrugated metal panels.

2. Gravel and concrete: Gravel is used to level the ground and provide a stable base. It helps with drainage and prevents water from pooling under the carport. Before laying the gravel, please clear the area of any debris or vegetation and ensure that the ground is relatively flat. Concrete is used to secure the posts of the carport. Concrete footings or piers are poured into the ground to provide a solid foundation for the posts. The posts are then inserted into the wet concrete and allowed to set, ensuring a stable and long-lasting structure. The concrete mix should be of good quality and properly proportioned to ensure strength and durability.

3. Screws: Screws are a crucial fastening element in the construction of a carport. A large number of screws are needed to attach the beams and panels securely. The screws should be of appropriate size and strength to withstand the forces exerted on the carport structure. Stainless steel screws are recommended for outdoor use as they are resistant to corrosion. When fastening the beams and panels, it is important to ensure that the screws are tightened properly to provide a secure connection. This will help prevent the carport from swaying or collapsing in windy conditions.

4. Tools: Other tools you may need include：The post hole digger is used to dig holes for the concrete footings or piers. Mason lines and a level are used to ensure that the posts are installed in a straight and level position. The mason lines help to align the posts, while the level is used to check for horizontal and vertical alignment.

A power drill can be used to drive screws and drill holes. The power saw can be used to cut the steel beams and panels to the desired lengths.

In addition to these tools, you may also need other items such as wrenches, pliers, measuring tapes, and safety equipment such as gloves and safety glasses. It is important to follow proper safety procedures when using power tools and working on the construction site.

How to build a steel carport?

1. Measure the perimeter

• Measure the required perimeter and mark it. For a family car, for example Toyota Camry, the space should be 16 feet long and 12 feet wide.
• Plot the exact locations for the holes to insert posts along the longer side of the carport. A single carport requires at least 3 posts on one side, while a larger carport will need additional posts for added stability.

2. Prepare the ground

• Clear out weeds using a shovel, level the soil, and use a level to ensure the surface is even.
• Add a layer of gravel.

Tip: If you are building your carport on a concrete ground you can skip this step.

3. Dig the holes

Use a post-hole digger to dig holes at least 2 feet deep at the marked post locations. In windy and snowy areas, make sure to check the frost line. The holes should be deeper than the frost line to ensure the long-term stability of the carport.

4. Set post

• Pour the mixed concrete into each hole and insert posts ensuring that they are vertical to the ground.
• Once all the holes are filled, allow the concrete to set for one day to secure the posts then check the stability of each post.
• The height of the posts from the ground to the beams should be at least 7 ft. Make sure to mark the required height on the posts and use a cutter to make the posts the same height.

5. Install crossbeams

• Secure the crossbeams to the tops of the posts using screws. This will create a stable frame for the carport.
• Assembling the panels onto the frame, start from the center and ensure that the panels overlap to prevent rain from leaking through.

6. Attach the roof and trim

• Fasten the panels along their seams and attach them to the beams using screws.
• Attach a trim to the edge of the panels for safety.

7. Prefabricated metal portable carports

Building a carport yourself is a challenge for most people without construction experience. Veikous prefabricated metal portable carports can solve this problem. The Veikous Metal Carport has a newly improved structure. This makes the frame more stable and makes installation easier. The metal carport can be installed according to the instructions and installation video.

• Screw the base tubes together, and anchor them to the ground.
• Connect the front, center, and back beamsto form a frame.
• Install themetal roof and rubber strip.

Metal carports built yourself are durable yet take time and effort to build. In contrast, prefabricated metal carport kits are simpler to install but require reinforced anchoring to the ground for long-term protection. Regardless of your choice, whether it’s a DIY metal carport or a prefabricated kit, your vehicles will be safeguarded.

Frequently asked questions about Carports

How long does it take to build a carport？

The answer varies depending on the type of carport you're planning to build. DIY a carport typically requires at least two days with help from another person. Building experience and the right tools will significantly speed up the process. On the other hand, installing a prefabricated carport is relatively simple and doesn't necessitate construction skills, but having a helper for a day can enhance efficiency.

How long do metal carports last?

Metal carports are generally seen as permanent since they are commonly anchored to the ground and cannot be moved. Using heavy-duty galvanized steel and regular maintenance can extend the life of the carport. Considering different ways to build a carport, it is advisable to check your local building codes about carports.
