PEB Explained: Structure and components
Pre-engineered buildings (PEBs) have changed the face of construction for industrial and commercial spaces and are performed in less time with low cost and scalable designs. Every PEB contains well-engineered components performing together on a structural basis. Below are the 10 key components of any standard pre-engineered steel building.
1. Primary Framing
It includes the main structural steel members, columns, rafters, and so on. These form rigid frames to carry most of the building's load and are usually built from built-up I-sections.
2. Secondary Framing
These are non-load-bearing elements such as purlins, girts, and eave struts. They support cladding and conveying loads to the primary frame.
3. Roof Sheeting
Roof panels made of pre-painted galvanized or galvalume steel sheets are intended for all-weather protection as well as aesthetics. The choice of roofing determines insulation, drainage, and longevity.
4. Wall Cladding
Wall panels protect the structure from external elements while adding to its appearance. Available in a multitude of profiles and finishes, wall cladding can also help in thermal regulation.
5. Bracing System
Bracings are steel members or rods placed diagonally to laterally stabilize the structure and resist forces such as wind or seismic activity. Cross bracing and portal bracing are two of the common bracing types.
6. Eave Struts
These are horizontal members located between the roof and the wall. It holds the panels and helps directly support the gutter system for efficient runoff.
7. Purlins and Laying Girts
Purlins (roof) and girts (wall) are cold-formed sections utilized to support the panels while reducing the span lengths. The Z and C shapes are optimized for strength and fast assembly.
8. Crane System (Optional)
PEBs would have crane-support systems, which more often than not would integrate into the design phase of the multi-story industrial structure such that anticipated vertical and lateral crane loads are handled seamlessly with the structure.
9. Mezzanine Floors
This intermediate floor creates additional usable space, typically for offices, storage, or utilities. It can be integrated into a structure without modifying the building's footprint and is supported by beams and joists.
10. Accessories and Trim
Elements such as doors, windows, ventilators, louvers, skylights, gutters, and trims are for enhancing buildings' usability and appearance. Completing a functional PEB is essential.
