The Z-shape is for purlins and girts and the C-shape is for eave struts. They are prepared by welding the steel coil in order to give it the desired shape. In this preparation, no welding is needed. Purlins, Girts, & Eave Struts: These are the secondary cold-formed members of the components of the PEB.These supporting the horizontal rafters are known as end wall rafters. The beam end wall system of framing consists of columns with pinned ends. End Wall Framing: This is designed as a main rigid frame.They are fabricated using the state of the art technology while the flanges are welded. The steel rigid frames are made up of, tapered columns and tapered rafters. Main Framing or Vertical Columns: The mainframes include the steel rigid frames of the building.The major components of PEB are divided into different types they are, The pre-engineered buildings are becoming popular in today’s world since they perform better than conventional buildings in terms of cost-saving and construction benefits. This leads to a potential saving in the structural framework. These buildings can be adapted to suit a wide range of structural applications. In order to design an accurate pre-engineered building, engineers consider a clear span between bearing points, roof slope, live loads, dead loads, wind uplift, and many more. These are built up with bolted connections. The components are fabricated at the factory to exact size, they are transported to the site and assembled at the site. Usually, pre-engineered buildings are steel structures and it can act as an alternative to conventional structural steel buildings. A pre-engineered building is a building that is made up of components that are manufactured at a factory and assembled together at a particular site. In the field of structural engineering, a pre-engineered building or (PEB) is designed by a PEB supplier or a PEB manufacturer that has a single design and that is fabricated using various materials and methods that can satisfy different types of structural and aesthetic design requirements.
