The Components and Structural System of Pre-Engineered Steel Framing
Pre-engineered metal buildings systems are a type of building enclosure that includes a structural system, often including roof and wall cladding. The structural system is made up of rigid frames, which are made from plate steel and then "cold-formed" by a manufacturing process.
These adjustable rooftop equipment frames are composed of roof beams and columns, which are field bolted together. Pre-engineered metal buildings are advantageous as they allow for large, column-free enclosures to be created.
Alternative structural framing options, like mill steel or light gauge metal, require more steel and are thus more costly to construct. Pre-engineered metal buildings are best suited for industrial applications, such as complex industrial facilities, warehouses, and distribution centers. It can also be used in shopping centers, motels, and auto dealerships.
THE COMPONENTS OF THE PEB SYSTEM
The primary frame of pre-engineered steel buildings is a portal frame construction that consists of primary and secondary framing and bracing system. Stable steel buildings are made from a combination of these elements and weather-covering sheeting.
Secondary structural frames
Secondary framing is mostly purlin and girt with Z or C shapes. Secondary framing is used in pre-engineered buildings to increase strength and reduce weight. Purlins/girt members transfer forces and moments between frames to ensure stability. They also serve as a framing system for weather-covering sheeting.
Roof and Wall Panels
Tin shades and curtain walls made from glass and roll-formed steel sheets are usually included in this category. The X-bracing system can be used to alter the direction of forces in order to reduce the impact of coercion. For x-bracing purposes, rods, pipes, and angles are usually used.
