Metal Carports and RV Covers

Are you in the market for a metal carport, steel building kits, metal building, or RV carport to cover your camper? Well, you have come to the right website.

Many people are surprised by our extensive service area and flexibility with manufactured portable carports.

The combinations to create a customized carport or RV cover that is unique to you are basically limitless!

When people are looking to cover their RV, they usually like to see pictures of tall camper covers and metal carports.

One of the most important things that RV and fifth-wheel camper owners look for is a metal awning that properly covers the entire height of their trailer, including the air conditioning unit on top.

It's necessary to have the right coverage for longer and taller RV's and motorhomes with metal carports and metal buildings.

Anchoring Metal Buildings and Carports

Concrete: How is my carport anchored to my concrete slab?

Holes are drilled into your concrete slab. Then wedge anchors are inserted through pre-drilled holes in the base rail of your carport, into the holes in the concrete, and securely fastened for a secure hold.

Ground or dirt: How is my carport or RV cover anchored to the ground or dirt?

32" long anchors are inserted through pre-drilled holes in the base rail. The anchors are driven into the ground with a sledge hammer for a secure hold.

For metal buildings installed on the ground in high wind areas, we offer an option for mobile home (or helix) anchors that are screwed into the ground and bolted to the base rails at a price of $50 each.

Asphalt: How is my custom structure anchored to asphalt?

32" long anchors are inserted through pre-drilled holes in the base rail. A small hole is made in your asphalt and the anchor is driven into the ground with a sledge hammer under the asphalt.

Wood deck or other wood surface: How is my steel garage building anchored to a wood deck or other wood surface?

Lag bolts are inserted through pre-drilled holes in the enclosed carport base rails and screwed into the wood surface for a secure hold. Please note, however, that carports installed on a wood surface, can no longer be certified for a specific wind and snow load rating. Some customers add anchor bolts and structural reinforcement after we anchor the base rail to the deck.

This illustrates the three carport roof styles available:

good roof
better roof
best carport roof


Size is just one important factor to consider when shopping and seriously considering a steel building for your property.

Width ranges: 10 feet wide to 40 feet wide (and more if necessary)

Length ranges: 21 feet long to 101 feet long (if necessary)

Wall height ranges from: 6 feet tall to 14 feet tall (with the peak being taller)

This means that you could have a 24x30 or a 30x40 or a 30x50 or a 50x100 - the size is up to you.

Question: What If My Metal Building Installation Site Is Not Level?

Answer: Keep in mind normal installations allow the ground to be 3-4 inches out of level from the highest corner to the lowest. However, if it is between 4 - 12 inches out of level you do have two options.

First, you can alter the site to create a situation that will allow for the installation of a steel carport on a level site by viewing what other customer's have done.

The second option is to pay a small labor fee and have our installation team trim the legs to allow for a level roof on your carport. Labor fees for leg trimming are very reasonable and are based on the length of your structure.

Just keep in mind that if it is more than 12 inches out of level, you will need to improve the site before construction occurs. We have the expertise to help fit the carport or metal building to your needs when it comes to things like an unlevel installation surface.

Not every location is going to be perfectly level, but we are happy to advise on how to achieve the best possible installation situation despite the location and circumstances.

Custom Metal Buildings and Steel Garages

Shopping for a metal building might start out to be a tricky task, but it doesn’t have to be. Custom steel buildings are easy to understand if you know the proper facts and become informed.

Steel max-rib panels are placed on the roof and sides for very durable steel buildings in the harshest of environments. You may be considering a structure for the job site and these are tough enough for double duty.

The way the structures are made includes the framing, materials such as braces, height clearance, features and appearance. The details involving climates, condensation, weather resistance, protection from the elements and winds help you get a better overall idea of how a well-designed building of steel can really make a difference for you.

A home is much more comfortable when there is enough space for everyone. Many people are even converting buildings of steel into homes now!

A cost-effective way to add more room and keep your things secure is to consider a carport or metal building. This way, you don’t have to add on to your existing home and have the expense and mess of construction.

How do our steel structures compare in price and details? Which layout would you prefer and where is the best place to have a structure installed? Some people wonder if there are prefab metal barns available. What are the construction costs for metal buildings and barns?

Have you ever seen a large steel structure used as a carwash with a garage door or vehicle emissions station and office space included?

The best thing to do when shopping for steel buildings is to do your homework first.

This is a great question.

Well, have you ever noticed that a mattress company always seems to have a blowout sale?

The same marketing tactic is used by many of the more disreputable metal building suppliers. They make it seem like they are offering their best sale ever or that you are really going to miss out if you don't buy buildings of steel now.
