Based on the local climate conditions and seismic requirements of the area where Mengxi Company is located, the primary structural forms include: rough stone foundation with steel-reinforced concrete independent foundations and steel trusses; rough stone foundation combined with composite brick wall columns and steel trusses; steel truss independent foundation with a door-type light steel rigid frame. The retaining structures mainly consist of masonry walls and color steel sandwich panels, while the roof systems include large roof slabs with thin web beams, gantry light steel frames with color steel plates, and triangular steel roof trusses. After several evaluations, the company chose between traditional masonry envelope structures and color steel panels for the walls and columns. For the roof, they considered grid color steel panels versus light steel color steel panels. The decision was largely influenced by the long construction period associated with large roof slabs and thin web beams, as well as the high maintenance needs of such roofing systems. Although the cost is similar to new materials, the appearance is unattractive, and this type of structure is rarely seen in areas like Zhangjiagang Economic and Technological Development Zone, Shanghai Zhangjiang Industrial Park, and Tianjin Development Zone. In addition to these drawbacks, there are also issues with difficulty in modification, dismantling, and an unappealing interior design. Color steel panels or sandwich insulation boards are still relatively new materials in China, especially in the central and western regions. However, they have been used in coastal developed areas for nearly 20 years. Initially, they were imported as complete sets from abroad and were mainly used in large-span warehouses and industrial plants along the Yangtze River. In recent years, their application has expanded to various types of buildings. These materials offer an attractive appearance, lightweight design, integrated thermal insulation and waterproofing, fast construction, minimal daily maintenance, and can be customized according to the owner's preferences. Most components are manufactured in factories, and on-site installation requires little labor. Due to their adaptability to different climates, they have achieved large-scale standardized production. While the price was high in the past, limiting their use, they are now widely adopted and gradually gaining acceptance across industries. Light steel structures have been used abroad for over 50 years, particularly in mobile applications such as military and field operations. They are known for their lightweight, ease of transportation, assembly, and disassembly, and can be customized in terms of height, span, and length. When combined with color steel retaining panels, they provide owners with flexible, comfortable, and clean spaces suitable for work, production, and living in mobile environments. Recently, the Chinese government has also promoted the use of light steel structures in commercial sectors. Their main advantages include lightweight, high standardization of components, and the ability to be mass-produced in factories. With increasing applications, the maximum span has reached nearly 100 meters. However, one disadvantage is that the overall rigidity is low, making it a flexible structure. It performs poorly under uneven loads such as wind, snow, and sudden impacts.
