Surface Air Film Coefficient (F)

The amount of heat flow in BTU's per square foot per hour between an exposed surface of a material and the adjacent air. It is the measure of the conductance of heat through the air film that clings to all surfaces.

Metal Shop Building

Renting a retail shop can be a risky commitment. Landlords and property management companies can be hard to deal with. Rent hikes, neglect of upkeep and deliberate refusal to service facilities are a few problems commonly encountered from renters. Owning your own metal shop building is ideal, even if you are just starting a new business, a metal shop building is a great asset for your retail or personal building investment. Make an inquiry with a steel building manufacturer to get the details about construction. Ownership is an excellent way to invest once and save for many years to come.

Trim and Gutter

The trim on a steel building serves two essential functions, to close transitions and protect the building from the weather. Trim also adds to the appearance of a building. Our sculptured trim gives the building a refined, quality appearance. Trim covers corner and edge areas of a building. For instance, eave trim creates a transition from the roof to the sidewalls and roof to endwalls.

Most metal building companies often supply "box" or generic trim pieces. This trim routinely has to be modified to fit, as it is created as multi-purpose - and does not fit well on standard panels. We fabricate each profile to match the design of your steel building. We do a lot of work in the shop that will save you headaches in the field. We hem all exposed edges of our trim so it installs easily, fits neatly, and looks great for the life of your building. Our trim is easy to install and adds to the look and the integrity of the building.

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.

Misleading Information - Deceptive Practices

The standards and values of our industry are regularly masked by the deceptive practices of the unprincipled few. These companies deliberately mislead people hoping to increase their chances of a sale. At Metal Building Depot we know that the more you understand about the product you are buying, the more confidant you will be at purchase time.

Arm yourself with information - No manufacturer keeps an inventory of buildings "ready to ship." Without exception, steel buildings are made specifically to order. A building should be designed to meet your needs and more importantly - your building code. Some companies create "general" price lists for common sizes, but the selection is very limited to a geographic area with limited variance in design.

Beware of companies implying they keep an existing inventory of buildings. To find out whether a "clearance" or "cancelled order" really exists inquire on the earliest ship date. You should be able to take immediate delivery on a building "ready to ship."

There is no such thing as making simple structural changes on a pre-designed building. Moving or adding a door opening on an existing or "ready to ship" building - could require the use of a wind column or portal frame. This could change the rigid frame design and render the existing design useless. Additionally, changing the wind or snow load could require the girt and purlin spacing to change and the location of connection plates along columns and rafters may not be located properly. The bottom line is that a structural change most likely requires a new building design. The moral of this story is: If a seller claims to have a building "ready to ship" make sure it will meet or exceed you local building codes and loads and more importantly - your needs.

Proposal or Propose "ALL" - We want to help you eliminate the "gray areas" in a typical building quote. The items listed on your contract should be made clear as to exactly what is being promised. Our itemized contracts are detailed and specific and you'll never see "included" in one price (without a description). All your accessories and options are listed as separate line items. With our online quote you will always know exactly what you're paying for.
