Color metal profiled steel plates are typically categorized into two main types based on the finished product processing method: veneer panels and composite panels. Veneer panels are primarily used in structures that do not require insulation or thermal protection, and they are often combined with internal rafters or wall beams to form the roof and wall system. On the other hand, composite panels are designed for buildings that demand thermal and heat insulation performance. These panels can be further divided into two series: factory-composite panels and on-site composite panels, depending on the construction and manufacturing process. Factory-composite panels are fully processed at the factory, including the core materials, and then assembled on-site. They are integrated with internal rafters or wall beams to create a complete roof or wall envelope structure. This type of panel offers a smaller on-site workload and faster construction time, making it ideal for large-scale projects with tight deadlines. However, the initial investment in equipment is significant, requiring a certain level of production scale to be economically viable. In contrast, on-site composite panels are manufactured as individual boards at the factory, while the sandwich core is assembled on location. This method involves a longer construction period but requires less equipment investment, making it more suitable for small to medium-sized projects. Currently, this approach is considered the most practical and widely used for color steel plate installations. The core materials commonly used in composite panels include polyurethane foam, polystyrene, rock wool, and glass wool. The choice of material should be based on factors such as project size, construction timeline, technical requirements, and local industrial capabilities to ensure optimal performance and cost-effectiveness.
