Roof Pitch

The angle of a steel building's roof is determined by roof pitch. Roof pitch indicates the rise vertically for every 12 inches of travel horizontally. Our online system allows you to choose up to a 6:12 pitch. There are many considerations with both higher and lower roof pitches. Higher pitched roofs may add to the cost of the building, but can add performance to a building in a heavy snow region. Additionally, you can take advantage of extra space above. High-pitched roofs are less likely to leak and can add style to your building.

Low-pitched roofs require less material and therefore cost less. Also it is easier to heat and cool a building with a low-pitched roof. One major advantage of a low-pitched roof is expandability. If you ever add-on to your building you will be able to add more space while keeping the loss of headroom to a minimum.

Structural Framing

All frames are welded on a state-of-the-art computerized submerged welding system. We are capable of producing structural members up to 72" in depth, which gives us the ability to manufacture clear-span buildings up to 150 feet wide! A factory primer coating is applied to protect the beams during shipping and erection.

All framing members shall be shop fabricated for field bolted assembly unless otherwise noted on plans and specifications. All building parts shall carry an identifying mark for easy field identification. Structural framing shall include tapered beam frames, tapered rigid frames, modular beam and columns, lean-to rafters and columns, canopy beams, intermediate columns bearing end frames and end wall columns. Steel used in the fabrication of built-up primary structural members shall have a minimum yield of 50 KSI. Hot rolled primary structural members shall have a minimum yield of 50 KSI. Cold rolled structural members shall have a minimum yield of 55 KSI. Primary framing shall be shop fabricated and include all holes required for attachment of secondary members and bracing. A continuous arc-welding process shall join flanges and webs of built-up welded members. End wall columns and rafters shall be "hot-rolled" built-up "I" or standard "cee" sections.

Connections - All field connections shall be bolted. All primary bolted connections shall be furnished with high strength bolts conforming to A.S.T.M. A-325. All secondary bolted connections shall be furnished with machine bolts conforming to A.S.T.M.-A307.

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:

Gutters & Downspouts

These are generally not required on steel buildings. However, use of these components often enhances the appearance of a building, control drip, splash and drainage.

Gutters and downspouts are an optional accessory that serves as trim. Gutters dramatically improve the appearance of buildings, and we recommend them for most building applications. Downspouts control the water falling from the roof, preventing the water from splashing up on the sides of the building.

On every Metal Building Depot building, die-formed ridge caps are used to cover the peak opening in the center ridge of the building. Some sellers provide a ridge roll cover that must be sealed with closures. Installing ridge roll trim is not an easy task. Over time the exposed foam closures deteriorate and there can be potential leak problems. Our die-formed ridge caps match the panel profile perfectly and are formed to fit the pitch of the roof. Die-formed ridge caps create an almost seamless transition across the roof.

Metal Buildings for Retail

Every retailer knows the importance of the manner in which merchandise is housed and displayed. In the highly competitive arena of retail sales, appearance can make a tremendous impact on attracting customers and influencing purchasing decisions.

Your retail facility can be enhanced with decorative brick, wood, stucco, glass, aggregate panels, landscaping and signage. A Metal Building Depot Acceptance Corporation dealer can help you with efficient designs and a more delightful appearance, yet stay within your budget.

Strip malls throughout the nation are being built with steel, utilizing the ability to add on or incorporate other fascia items - representing savings of up to 30% over other conventional construction methods. Owners and developers have come to realize that the pace at which a steel building system can be designed, manufactured, delivered and completed, is measurably less than that of any type of conventional construction. The short completion time and overall durability of steel building systems assure a more efficient turnkey project, as well as a quick return on the initial investment.
