Large Prefab Buildings That Hold Up in Snow and Wind

Our large and extra-wide clear-span buildings are designed with the vertical roof style. This roof design allows the snow to slide off instead of weighing on your building. These roof styles look good and are super-easy to maintain. Steel is known to last way longer than lumber and is easier and time-effective to put up than concrete. So for shop buildings, warehousing needs, or retail/office space, buy a Pre-engineered Boss Building.

We offer horizontal and vertical PBR paneling on the carports and pre-fab large commercial steel structures. With this, you can enclose your big metal building and the installation crew will do a perfect job to make a large fully enclosed garage on your lot of land. We build our trusses according to your load and speed codes.

Our prefab big buildings are manufactured to support 140 miles strong winds and 35 pounds of ground snow load. However, these codes can be upgraded to 170 MPH winds and 65 PSF snowload. Our special trusses are placed 3D’ or less apart for higher-rated wind and snow rated prefab commercial large steel buildings. This leg spacing (also known as 3’ or less on centers) are anchored using a host of anchoring solutions such as the rebar, ground, mobile-home, or concrete anchors.

Sizes and Specs of Large Metal Buildings and Pre-fab Carports

These large metal storage buildings can be built with 14-gauge steel tubing or a thicker 12-gauge steel tubing. The tube framing comes with a 20-year rust-through warranty to ensure that these commercial carports are long-lasting. Our 32-to-60-foot-wide metal buildings are anchored for free to your level concrete pad with cement anchors or to the ground with mobile home anchors. The side height on these steel buildings comes standard with 8-foot legs but can be made taller with a 10-, 12-, 14-, 16-, 18-, or 20-foot-tall side height if you need an extra-large metal shop size

What Buildings Are Considered Big Buildings?

Metal buildings that are longer than 52’ are usually considered big buildings. Why 52’? Because that is the longest custom size most of the steel buildings & structures contractors build. Any prefab steel garage or pre-engineered carport, longer than 52’ in length (the gable end of the building), requires an end-to-end connection. Boss buildings can build commercial shop buildings, steel warehouses, and other buildings, and the prices depicted below are for 8’ tall metal structure that is top-only(open). Remember, you can customize a Boss Building by adding panels to enclose or partially enclose your building.

You can also select your colors for roof, trim, and walls, and you can also add accessories including framed openings, garage doors, Dutch-style openings, cupolas, and skylights. Our commercial buildings for sale are delivered and installed free for the quote of pre-fab extra-span building that we provide to you.
