Construction materials are very important when building a portable structure. Considering that most times you aren’t heating or cooling the inside of a portable storage building, the materials are continually expanding and contracting. When this happens, joints shrink and expand with the temperatures and if the materials are not high quality, this can cause air gaps or leaks which would allow the elements to enter and degrade the structure. With a portable cabin, you may or may not have continual air conditioning and heat, which makes it even more important to use the best materials.

Using kiln dried lumber for framing and choosing an exterior covering that will last and hold up to the elements is critical. Sheathing the exterior walls with metal is even more critical because it will certainly take a beating. Our Portable Storage Buildings, Portable Cabins and Portable Barns all come with metal cladding. This product is steel roofing with hard, baked on paint which is designed to protect the roof and sides of the building. Super durable and low maintenance, these panels will not need any painting for many, many years if ever.

We deliver your portable building and set it up on your level lot using our amazing mechanical Mule. This enables us to place your building in the precise spot without damaging the lawn. We offer free delivery within a 50 mile radius of our location and if you’re over 50 miles, we’ll quote you an affordable price on the additional mileage.
