Components/Accessories

Which base trim option should I choose? - The base trim that you choose for your steel building will depend on your building's needs and the type of foundation you use. Although we strongly recommend a notched base, we do offer several additional base trim options to suit your specific needs. Please see base conditions for more helpful information and illustrations.

What type of windows do you offer? - We offer a selection of windows for your building. To learn more about what's available please visit the accessories section of our website.

What comes with the doors and windows? - All of our doors and windows come with the required hardware to install them into your steel building. We provide the framing, trim, and flashing for a proper installation.

How do I know where to place my windows and doors? - Windows and walk doors are generally "field located." You, as the customer, will pick the location, cut the corresponding panel to size and proceed to mount the doors and windows. If you choose to include a large number of windows or doors we may ask you to give us your proposed location to ensure proper building bracing.

How do I attach my doors and windows? - All of our walk doors are self-framing, so they include the necessary items to mount them on your building. Our windows are secured by screwing the window trim directly into the building. This is also known as self-flashing. If you live in a high wind area, please talk to one of our design consultants about additional door and window mounting options.

What is the R-Value of your insulation? - The r-value of our insulation depends on the thickness you choose. It will vary between R-10 and R-19. Please see the r-value section of our website for more helpful information.

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.

Engineered Buildings

Don't be reluctant to purchase an engineered building because you think that it will limit your options. There are unlimited building styles and configurations to choose from. A person needing a metal church building will most likely want a different construction style than someone looking to erect a steel building horse barn. For this reason, engineered buildings are as diverse as the purposes they are used. If you require assistance in addressing your particular needs and specifications many steel building manufacturers offer design services to walk you through the process, some even offer online design programs.

Most pre engineered metal building manufacturers will have a common design that suits your needs, but never hesitate to ask for custom designed plans. A qualified manufacturer should make no hesitation in designing the exact building you desire.

Mini Storage Buildings

If you have thought of being a small business owner you might consider the self-storage market. Self-storage and mini storage buildings are a fairly inexpensive way to start a business that is designed to bring in dependable monthly revenue. Many storage facilities currently have waiting lists due to the ever-growing need for space. Mini storage buildings can be designed to include any number of individual units, depending on the site constraints. Steel frame mini storage buildings can be designed with a variety of options.

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:
