A primary framing system forms the structural backbone of pre-engineered or steel buildings. It includes essential components like columns, rafters, and beams, designed to carry the building\'s load and transfer it to the foundation. These frames are typically made of steel and are engineered to withstand various stresses, including wind, snow, and seismic loads. The primary framing system provides stability and rigidity, ensuring the durability and safety of the structure. This system is customizable based on the building\'s purpose, making it ideal for warehouses, factories, commercial buildings, and other large-scale applications.
