Pre-engineered buildings (PEBs) are structural buildings that are engineered and manufactured off-site. They are composed of steel frames and roof/wall panels, which are assembled on-site. PEBs offer versatility for industrial facilities, warehouses, commercial buildings, and more. They provide advantages such as faster construction, cost-effectiveness, design flexibility, durability, and resilience to environmental conditions. PEBs are a popular choice due to their efficient construction process and customizable features. With off-site manufacturing and on-site assembly, pre-engineered buildings offer a modern and efficient solution for various construction needs.
