PEB warehouses are usually made from a steel frame, with exterior walls and roof panels that are also made from steel. The steel components are prefabricated in a factory and then shipped to the site, where they are assembled using bolts or welds.
This allows the building to be erected quickly and with minimal on-site construction. PEB warehouses are also often designed to be easily expandable, so they can be easily modified or expanded as the needs of the business change.
