Heat Transfer

Effectively controlling temperature in a steel building requires insulation to be present along exterior walls and roof. When a temperature differential is present in an enclosed steel building, heat will work from warmer areas to colder areas until the temperature in the building has stabilized. At the point of thermal stabilization, the cooler (and heavier) air will be present at lower elevations and warmer air will be present at the roofline. The function of insulation is to help stabilize air temperature at more desirable levels. When it is hot outside, preventing heat from transferring into the building is the goal, and of course in the winter we want heat to remain inside.

Heat transfer occurs in three ways:

Conduction : Occurs in a solid or liquid when heat from one object is transferred by touch to another object. An example of this occurs when a pot on a stove will heat up by conductive heat transfer from an electric coil.

Convection : Occurs with the physical movement of air. There are two types of convectional heat movement. The first is natural, where hot air rises displacing the cold air and moving it down. The second type is forced or mechanical convection. This occurs when an object, like a fan, physically moves or "forces" the air to move.

Radiation : Occurs when an object is warmer or hotter than the air around it. For example, the sun, which is hotter than everything around it, radiates heat waves that travel through the air and is either absorbed by or reflected by the surface it comes in contact with.

Visible Condensation

To effectively control visible condensation, it is necessary to reduce the cold surface areas where condensation may occur. It is also important to minimize the air moisture content within a building through the use of properly designed ventilating systems.

Metal Buildings

Maybe you have already purchased a small backyard storage unit. If so, you have more than likely discovered that it offers inadequate space. A custom designed metal building can still easily fit in your backyard and provide you with the space you need.

Steel buildings can be designed to your specifications; these buildings are complement to your home. Youngsters appreciate the extra space to play, practice, or hang out with their friends. If you are in need of extra space but can't afford pricey construction work, a pre-engineered metal building is the way to go.

Frame Features

Connection Clips - Specially fabricated clips are designed to securely connect structural components. Many companies supply only blank plates that must be cut, drilled and/or welded to components before assembly can begin. In some cases it may require many hours of work to connect required clips. Metal Building Depot details and supplies each clip and placement to every building manufactured. We factory weld all clips onto rigid frames and guarantee the correct placement of all component connections. Don't waste your time and money attaching clips that should have been factory located.

Structural Bracing - Most buildings under 60' have sufficient diaphragm action or "panel shear" that provides all the bracing needed to stabilize the building. In some cases of high winds, seismic or snow loads may cause more stress than panel shear can handle, so additional reinforcement may be required. In these extreme cases we will employ the use of X bracing to reinforce the frame. In situations where X bracing cannot be used a wind column is an excellent addition to strengthen a vertical rigid frame column. A portal frame is sometimes used in extreme load circumstances. Portal frames are fairly expensive and only necessary in rare circumstances.

Roof Pitch

The angle of a steel building's roof is determined by roof pitch. Roof pitch indicates the rise vertically for every 12 inches of travel horizontally. Our online system allows you to choose up to a 6:12 pitch. There are many considerations with both higher and lower roof pitches. Higher pitched roofs may add to the cost of the building, but can add performance to a building in a heavy snow region. Additionally, you can take advantage of extra space above. High-pitched roofs are less likely to leak and can add style to your building.

Low-pitched roofs require less material and therefore cost less. Also it is easier to heat and cool a building with a low-pitched roof. One major advantage of a low-pitched roof is expandability. If you ever add-on to your building you will be able to add more space while keeping the loss of headroom to a minimum.
