Panel Profiles

Roof Panel Profiles - Our standard roof sheeting is the "PBR" panel, which is available in bare Galvalume Plus® as well as a variety of colors. Wall sheeting is available in "R" and "PBR" panel. Depending on the color and your geographic location - PBR panels may not be available for certain colors.

Liner Panels - For liner panels we offer a low-rib 29-gauge panel. Liner panels are an interior covering for the walls of a steel building. Like exterior walls, liner panel consists of 3-foot wide panels that are attached to the framing in the same manner as exterior sheeting. Full-height liners run from floor to roof. Partial-height liners typically attach to the girt at 7'4" and extend a few inches above it. Buildings with liner panels must have a base connection for the bottom of the panel (see base conditions).

Advantages - Liner Panels enhance appearance, providing a finished look for the interior. The biggest advantage is that liners protect the insulation and the outside walls. Because un-reinforced insulation facings tear easily, and even the best-reinforced materials can be damaged, liner panels are the intelligent solution to protect your investment. Although 26-gauge exterior walls can withstand a lot of punishment, a steel liner will protect your building's interior and performs at a lower cost than other wall coverings, which will require their own framing.

Thermal Conductance (C-Value)

A measure of the amount of heat that passes through materials of any thickness.

Condensation Control

The condensation process occurs when warmer moist air comes in contact with cold surfaces such as framing members, windows and other thermally conductive accessories, or the colder region within the insulation itself (if moisture has penetrated the vapor retarder). Warm air, having the ability to contain more moisture than cold air, loses that ability when it comes in contact with cooler surfaces or regions. When this happens, excessive moisture in the air is released in the form of condensation. If this moisture collects in the insulation, the insulating value is decreased.

In dealing with condensation, air may be considered to be a mixture of two gases-dry air and water vapor. One thousand cubic feet of air at 75°F can hold up to 1.4 pints of water. At 45°F, it can hold only 0.5 pints.

Relative Humidity is a percentage measurement of the amount of water vapor present in the air in relation to the amount it is capable of holding at that temperature. Therefore, 50% Relative Humidity would mean that the air is carrying only one-half of the total amount of moisture that it could be holding at that particular temperature. Cold outside air is usually much drier than warm inside air. Therefore, you can lower the Relative Humidity by bringing in outside air to mix with and dilute the moist inside air. At 100% Relative Humidity, the air is "saturated."

The temperature at which the air is saturated and can no longer hold additional moisture is called the dew point temperature. Whenever air temperature drops below its dew point, excess moisture will be released in the form of condensation. Condensation problems are most likely to occur in climates where temperatures frequently dip to 35°F or colder over an extended period of time.

COMMERCIAL OFFICES

Your place of business should and can be more than just a place to work. It should reflect your company's image and be no less comfortable, functional or attractive than your living environment. Entry-ways and lighting, interior wall placement, and location of restrooms are as important in your office building as they are in your own home. Properly planned, your facility will serve your needs for many years to come, and you will avoid future changes or costly remodeling.

Modern ceiling and interior wall systems are very easily adapted to our manufactured building components using standard methods. For instance, perimeter sheet rock walls may be installed by simply attaching metal furring strips (hat channel) to the secondary wall framing members (girts). Similarly, acoustic panel or dry-wall ceilings may be installed by simply wrapping the ceiling suspension wires around the secondary roof framing members (purlins). Additionally, port-a-wall systems may be installed as needed throughout the structure.

Additional loads from heating and air conditioning systems, dropped ceilings, electrical conduit and lighting fixtures, or large mechanical sprinkler systems can be accommodated easily at your request with minimal cost, assuring a full roof-load certification.

The building components may represent a small percentage of the total cost of your office budget. Therefore, we are careful to ensure that the main structural components we provide will be reliable, helping to protect your investment against any water seepage, leaks or storm damage that can deteriorate your office complex.

When selecting the manufacturer of your building components, careful consideration must be given to both function and price. Your dealer will encourage you to have an architect review all aspects of your building plan, including lighting requirements, window heights, storage space, carpet wear ability, entrances, landscaping, parking and signage, to ensure you of a facility that will maintain its value and be a source of pride for years to come.

Frame Types

Unlike any of our competitors, we allow you to price all building frame types. Select from Clear-span or Modular rigid-frame buildings. We allow you the full flexibility to choose Gable, Single Sloped or Offset Peak building shape. By far, we offer the widest selection of building and frame types. For options not available through the online system, you will need to request a special quote.

Clear-span Frames - A clear-span rigid frame offers strength and economy. Since no interior supports are necessary, this design is best when you require large areas of clear and uninterrupted space. Factories, warehouses and agricultural buildings are just a few building types that may utilize a clear-span frame building. A clear-span design does have size limitations. As the desired width increases, the frames will become larger and heavier to carry greater loads across the length of the frame. At some point the cost will outweigh the benefit. Even so, clear-span buildings are still effective for buildings as wide as 150' feet and wider in some cases.

Modular Frames - Modular frames use interior columns to evenly distribute the load; reducing the cost of both the frame and foundation of extra wide buildings. The economical advantages become obvious when a building width is about 100' wide or wider. As a result, almost all buildings 100' wide or wider have interior support columns. Modular designs are often used for large factories and warehouses.

Single Slope Frames - Single slope frames have high and low eave heights creating a roof that "slopes" from side to side. To select a single slope design, you specify one eave height and define the roof pitch. Single slope designs are frequently used for strip shopping centers, offices, and RV/Boat storage facilities.

Just about every steel building has at least one framed opening. It is not unusual for buildings to have several openings. Most openings are created for an overhead door, but can be used for the installation of glass fronts or other entries. Most other online sellers offer "field located" framed openings, which require cutting and fabricating on the job site. Metal Building Depot always provides factory-located openings unless your project requires something otherwise.
