Secondary Framing

X - Bracing

X-Bracing is used in buildings to provide additional bracing and strength. X-bracing is very economical and the most common bracing system MBMI offers. Bracing design depends on the steel building size and the local county loads. Our design engineers create a bracing system that is economical, yet very strong. This can be accomplished with steel cables, solid rods or even steel angle in severe cases.

Wind columns

Wind columns are used when x-bracing causes an interference with openings in a particular wall. Whether there are doors, windows or open walls, wind columns are an economical substitute for standard x-bracing. A wind column is basically an "I" beam that bolts to the rigid frame and the foundation to provide strength and rigidity.

Portal frames

Portal frames are used when you have the same situation as a wind column, but a wind column does not provide enough support. These frames are usually used on larger buildings and steel buildings with very high snow or wind loads. When x-bracing is not allowed in a wall and a wind column is not strong enough, a portal frame is used. Portal frames are very heavy frames that connect two rigid frames and increase the lateral support greatly.

Welded clips

All of our girt and purlin clips are factory welded on all structural steel. Some of our competition uses bolted clips on the structural steel which take longer to install and are not as strong as a welded clip. MBMI uses welded clips to save you time and money when erecting your metal building.

Endwall framing

Endwall framing can be designed many different ways. Endwalls can be built with C-channel, welded I-beams and even rigid frames depending on the situation. Endwalls can be designed to be closed or open depending on your application. The strength of the endwall components depends on the size and loads of the steel building. Our engineering staff can design the perfect endwall for your needs.

Girts

These steel members span the length of the building between frame lines on the walls. The wall panels are fastened to these members and provide the strength and framework of the walls. Girts are pre-punched "Z" shaped with a yield strength of 55,000psi and fabricated in 12, 14, and 16 gauge depending on the building loads. If your application calls for a spandrel beam, MBMI can supply heavy channel or I-beam sections. MBMI girts are bolted to the welded clips without any welding or cutting. They are coated with a durable primer that will protect the steel from rust and corrosion.

Purlins

These steel members span the length of the building between frame lines on the roof. The roof panels are fastened to these members and provide the strength and framework of the roof. Purlins are pre-punched "Z" shaped with a yield strength of 55,000psi and fabricated in 12, 14, and 16 gauge depending on the building loads. MBMI purlins are bolted to the welded clips without any welding or cutting. They are coated with a durable primer that will protect the steel from rust and corrosion.

Eave strut

These steel members span the length of the building between frame lines on the roof at the eaves of the building. Eave Struts are pre-punched "C" shaped with a yield strength of 55,000psi and fabricated in 12, 14, and 16 gauge depending on the building loads. MBMI eave struts are bolted to the rigid frames without any welding or cutting. They are coated with a durable primer that will protect the steel from rust and corrosion.

Roof extension

Roof extension can be added to any building and to any wall. Roof extensions can follow the roof line or can be designed below the roof. Roof canopies are great at providing covered area without any columns. This is the most economical way to keep the sun, rain and snow off the wall of a building and to cover openings or walkways. MBMI extensions are available with & without soffit panels depending on the look you want.
