prefab

Basic components of prefabricated steel industrial buildings. Good material properties and high reliability. The steel is produced by the factory, with strict quality control, good material uniformity, and good plasticity and toughness, which is more in line with the ideal isotropic elastic-plastic material. Therefore, the currently adopted calculation theory can better reflect the actual working performance of the steel structure, high reliability. Cold-formed thin-walled purlins are the main sub-structural form of portal rigid frame structure systems with a column distance of less than 12 meters. The commonly used purlin spacing is 1.5m. High-strength hot-dip galvanized materials are used, which are continuously rolled and formed by the production line, with standardized pre-punching holes, C and Z section specifications, and are connected in a simply supported or continuous manner. · Z-shaped purlins are mostly used in the design of continuous purlins on house walls; · C-type purlins are mostly used in walls, door and window openings, etc.
