Steel is a material that you can count on no matter where you live.
In the south, severe storms with excess rainfall or high winds are no match for a good quality steel outdoor shelter.
The same can be said for the cold frigid temperatures of the north.
Excess snow and ice will not pose a problem for your steel structures.
Most steel product manufacturers offer a warranty with their products because they are confident in the materials and in their manufacturing processes.
If you are debating whether or not to pay the extra cost of getting a steel frame carport for your vehicle, consider the cost of maintenance to any other shelter material.
Wood, vinyl, and even aluminum can be damaged easily or deteriorate over time.
Long term exposure to humid or damp conditions can cause a wooden shelter to decay and collapse.
Carports made from aluminum can easily rust under the similar conditions.
A hail storm can cause dents to the surfaces of an aluminum structure which is left alone will eventually begin to rust.
A fire can easily damage a wooden or vinyl shelter beyond the point where you can repair it yourself.
You will likely need to tear the whole thing down and purchase a new one.
Even though a steel carport will weight more than one that is constructed from aluminum or vinyl, you should still find that it is easy to construct.
You should definitely not have a problem assembling a kit.
Kits come prefabricated in large pieces that may need more than one person to lift but once in place, fasteners are all that is needed to attach the pieces.
Once you have all of the pieces in place and fastened together you will likely want to anchor the entire shelter in place.
This is usually accomplished with anchors which may or may not be included in the kit.
