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.

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.

Steel Buildings

Why should I build with steel instead of wood? - The number one reason is strength. Steel buildings can withstand high load conditions. Steel buildings are fastened together with high-strength bolts and screws. The connections remain secure because there is little to no movement in the structural members and panels. However, wood connections in conventional construction become loose due to expansion and contraction and the result is warping of the wooden frame. Steel does not warp, shrink, or change with time so the connections remain secure. Wooden buildings can suffer damage do to insects such as termites, and this deterioration will reduce the quality of wooden buildings. Furthermore, metal building material is not a flammable substance so your insurance costs will be reduced.

How does the price of a steel building compare with others? - Conventional construction materials are affected by demand and availability; conversely, steel has remained relatively constant for many years. When it comes to pre-fabricated steel buildings it would be difficult to find a like structure to compare with the low cost of a steel building.

Is everything I need to construct my building included? - Everything you need to construct your new metal building will be included with the exception of the anchor bolts, which should be supplied by your foundation contractor.

What is Bay Spacing? - It is the space between 2 frames. For example, the end wall of the building is the End-Frame, and the distance between the End-Frame and the next column/rafter section is the Bay Space, or the distance between two column/rafter sections.

How do I assemble my steel building? - Steel building assembly couldn't be easier. We provide you with the necessary information to erect your steel building quickly and efficiently. Many of our clients erect their steel buildings on their own, although a professional contractor can also used at an affordable price.

Are the steel buildings painted? - Yes, the walls and trim are painted with a long-lasting factory-applied paint manufactured by a leading manufacturer of heavy duty, high performance protective coatings for steel building components. There is a wide selection of colors for you to choose from. You can select the wall panel, trim, and roof colors on the color chart section of our website.

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.

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.
