Primary framing refers to the main structural system of a pre-engineered metal building (PEMB). These are the load-bearing components that support the building’s weight and resist external forces like wind, snow, and seismic activity. These primary steel framing members are produced in-house at a new advanced manufacturing facility and are available from Central States Building Works as part of a complete metal building design.
Key Components
Rigid frames include robust columns and rafters to form the building’s skeleton. Vertical integration through our advanced Steel Frame Plant manufactures high quality members.
End wall frames serve as the structure at each end of the building. The new Building Works Frame Plant produces numerous end wall frames like heavy girts and lateral braces that support the various building envelope components made from metal sheeting, insulated metal panels, brick veneer and EIFS, or CMU.
Primary structural use moment and shear connections. Moment connections resist lateral forces without bracing, using strong welds, bolts and stiffeners. Shear connections allow rotation and rely on other systems for lateral support, using bolted or welded web joints. Central States Building Works produces these critical pieces with precision welds and cuts, tight tolerances, and clean connections.
In-house frame manufacturing gives Central States Building Works customers the options for multiple frame profiles, whether hot rolled, bolt-up, cold formed or light gauge. Available in extensive building widths with customized bay spacing and a wide variety of roof slopes.
Central States Building Works engineers have options for primary framing structures to meet customer requirements. Our surface preparation and automated painting of red oxide or gray primer finish ensures the highest quality.
Using state-of-the-art technology, Central States Building Works produces primary framing structures in-house, benefiting customers with consistent quality, streamlined communication, and faster lead times.
Central States Building Works designs and fabrications pre-engineered metal systems, including in-house frame production at our new advanced Steel Frame Plant.

Primary framing serves as the anchor for secondary framing. Purlins, girts, and bracing systems attach to the primary frame, distributing loads and supporting the building envelope.
