Ceiling & Wall Liners

29g low rib panel applied to the interior of the building providing a clean protective covering over insulation or girt/purlin cavity.

Insulating Against Radiant Heat

Traditional forms of mass insulation, like fiberglass, are effective in preventing heat transfer by conduction and convection, but they less effect on radiant heat. Between 80 and 90% of the radiant heat striking fiberglass will pass through or be "emitted". Radiant transfer typically has as much impact on the temperature in a building as conduction and convection. For more information on radiant barrier facings click here.

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.

Secondary Framing

Secondary framing is created from rolled steel coated with a red-oxide primer finish in gages from 12 to 16 to provide an extremely rigid, and corrosion resistant structure. The following elements are formed as secondary framing:

Girts (walls) & Purlins (roof): These members run the length of the building providing rigidity, and a sturdy skeleton to attach the sheeting. They are rolled from steel coils 12,14 or 16-gauge steel, or thicker if needed. All girts and purlins are pre-punched for ease of assembly.

Eave Struts: This is a rolled member formed into a "C" to match the pitch of the roof. The eave strut is also made of 12, 14, or 16-gauge steel.

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.
