Steel Frame

Metal buildings are strong. It is the nature of their design. Because they are built to survive the harshest conditions, you can rest assured that you investment will last for years to come. The basic design provides great structural stability, even in an earthquake or windstorm. The rigid steel frame reinforces the secondary structural framing system. Any building is only as good as its foundation. A steel frame is the ultimate starting point for your building.

The last thing you need to worry about is the structural integrity of your office, shop or storage buildings. An advantage with pre-engineered buildings is there are no roof shingles for you to worry about replacing later. A smart investment is one that requires the least amount of cost now and in the future. Steel frame buildings are just such an investment.

If you have questions about steel frame buildings, just turn to an expert. There are many qualified steel building manufacturers to answer any question that you may have.

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.

Installation and Selection of Insulation

We provide the highest quality products available. However, proper installation and selection is imperative for maximum effectiveness. Please refer to installation instructions to ensure correct procedures are used. Facings that have been torn or punctured are no longer capable of blocking water vapor and may eventually do more harm than good. Be sure to quickly patch any holes in the vapor barrier.

When selecting a facing, special consideration should be given to its reflective quality. A facing with high reflectivity reduces the need for high light levels in work areas. This results in reduced energy costs and increased productivity.

Although the fiberglass insulation itself is not affected by cold weather, the facing is. Colder temperatures can cause cold crack, a situation where the facing becomes brittle and if handled can crack. Bay Insulation recommends that vinyl faced fiberglass products never be installed in temperatures below 40 degrees.

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:

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.
