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.

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.

Ridge Vent

Ridge vents come completely assembled for ease of installation. Ridge vents supplied by Metal Building Depot are of a low profile design to provide gravity type ventilation. Because gravity ridge vents are designed to allow free airflow, some penetration of water during blowing rains is to be expected. Standard available finishes for the ridge vents are polar white and galvalume. Other colors may be available at an additional cost. Nominal ridge vent length is 10'-0". Ridge vents are available with 9" and 12" throats. Bird screens are provided as a standard. The ridge vents can be ordered as continuous or single units. Exterior parts are 26 gage painted or galvalume. Interior parts are all made of G90 galvanized steel. The substructure consists of 10 gage saddle straps with interior baffles of 24 gage steel. Lifter arms and damper slides are made of 18 gage steel. Manual operation is through activation of a pull bar which is attached internally to bell cranked type lifter arms connected to the damper with Teflon coated pins through the damper slides. Dampers are spring loaded to remain in the open position until the pull bar is operated and locked in the closed position. Dampers operate in a vertical manner. Each vent is opened by a pull chain that extends approximately 12" below the roof unless noted otherwise on the order documents. Other opening mechanisms are available at an additional cost upon special request. Ridge vents should not be placed closer than 5’-0" to the endwall steel line to allow room to properly flash the building. For example, a 90’-0" long building with ridge vents required the entire length should have no more than (8) units. The ridge vents are available with the following accessories:

On The Farm

I don't know of any farm operation that could get buy without barns for equipment storage, feed storage or any other general warehousing needs. Many older farms are now removing old wooden structures and replacing their old buildings with new steel structures. While the old antique tractor may look good in front of the old barn, many are weary of storing precious items in an old rotten structure. Steel is stronger, straighter and will last eons longer than wood. In a home, wood is fine. Houses are designed so that the wooden structural components do not have direct exposure to the elements, but on the farm it is often hard to prevent the outside from coming into the barn.

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.
