Roof Extensions and Overhangs

Extensions can improve the appearance of a building but will cost more. Roof extensions add "curb-appeal" to some buildings, but will take more time to complete the erection of the building because of the amount of extra covering trim. Extensions can also help a building merge in better in an environment of conventionally constructed buildings in commercial areas. An overhang offers you some protection from the rain and shade from the sun. These options can be important when you receive many visitors to your building, by offering shelter from the elements.

We offer two types of roof extensions: (1) Gable Extensions for endwalls (2) Eave Extensions for sidewalls. Using our system, you can easily and quickly design and price buildings with overhangs up to 5' on any or all of the walls. When in the Building Accessories section select Roof Extensions.

Why are steel buildings so popular?

That's easy. Price. All around price. They are less per square foot than any other known form of construction, and can be erected quickly, offering its owners faster access to their new building. We are seeing more buildings sold for residential use. People are putting up shops and garages faster than you can count. As rural America gets divided into smaller ranches, we see the increase for barns, arenas, horse stalls... etc.

Foundations

Do I need a foundation for my metal building? - Some people choose to pour a full slab foundation, however if you're planning on leaving the floor in a dirt or gravel condition, concrete piers will do the job just fine. Please contact a customer service representative if you don't plan to pour a full slab foundation.

Can you provide an engineer stamped foundation layout? - Yes, but in some cases your soil conditions play a major role in the type of foundation you can use. Contact our special sales department for more information. If using a local engineer, we will provide anchor bolt plans to aid your engineer in designing the foundation.

Do you supply the hardware to attach the frame to foundation? - No, the anchor bolts are usually supplied by a concrete contractor and placed when the foundation is poured.

Frame Features

Connection Clips - Specially fabricated clips are designed to securely connect structural components. Many companies supply only blank plates that must be cut, drilled and/or welded to components before assembly can begin. In some cases it may require many hours of work to connect required clips. Metal Building Depot details and supplies each clip and placement to every building manufactured. We factory weld all clips onto rigid frames and guarantee the correct placement of all component connections. Don't waste your time and money attaching clips that should have been factory located.

Structural Bracing - Most buildings under 60' have sufficient diaphragm action or "panel shear" that provides all the bracing needed to stabilize the building. In some cases of high winds, seismic or snow loads may cause more stress than panel shear can handle, so additional reinforcement may be required. In these extreme cases we will employ the use of X bracing to reinforce the frame. In situations where X bracing cannot be used a wind column is an excellent addition to strengthen a vertical rigid frame column. A portal frame is sometimes used in extreme load circumstances. Portal frames are fairly expensive and only necessary in rare circumstances.

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.
