Prefabricated Panels for Steel Structure Factory Building Roofs
Prefabricated panels for steel structure factory building roofs can utilize steel frame lightweight panels, which use galvanized steel frames as the load-bearing structure and are filled with Class A non-combustible thermal insulation cores. These panels combine lightweight strength, thermal insulation, fire resistance, and sound absorption properties, making them an ideal choice for steel structure factory building roofs.
Product Features and Performance Advantages
- Material Composition: Steel frame lightweight panels feature galvanized steel frames as the core load-bearing structure, filled internally with Class A non-combustible thermal insulation cores (such as BAS ultra-lightweight concrete, 'Pengshi' high-strength inorganic lightweight materials, etc.), and covered with flexible waterproof layers or specialized panels. For example, Tianji panels combine light steel frames, high-strength corrosion-resistant steel wire mesh, BAS core layers, and waterproof layers, achieving a thermal conductivity as low as 0.07–0.08 W/(m·K). The core thickness is adjustable to meet different thermal insulation requirements.
- Load Reduction and Enhanced Safety: The lightweight nature significantly reduces the load borne by the building structure, while the synergy between the steel frame and the core enhances overall safety and durability. For instance, the Golmud project employed 180mm-thick prefabricated panels, maintaining structural stability even under extreme climatic conditions.
- Strong Environmental Adaptability: Designed for harsh environments such as high altitudes, large temperature variations, and strong winds and sand, steel frame lightweight panels utilize a composite design of galvanized cold-formed thin-walled steel or angle steel truss frames, thermal insulation cores, and specialized panels to achieve thermal insulation, fire resistance, wind and snow load resistance, and the ability to support maintenance personnel.
- Convenient and Efficient Installation: The factory-prefabricated, on-site hoisting and welding process significantly reduces wet work volume, with a single-shift installation capacity of up to 2000㎡/day. The Golmud project achieved rapid construction with controllable quality through standardized node designs.
- High Standardization Level: Board selection and node design are carried out with reference to national standard drawings (such as 16CG27, 16CJ72-1), allowing construction teams to work according to the drawings and ensuring consistent quality.
Application Cases
Steel frame lightweight panels have been widely applied in industrial plants, warehouses, sports venues, and other fields. For example, the Golmud steel structure factory building project adopted prefabricated assembled lightweight panels, achieving standardization and rapid installation of the enclosure system; Tianji panels are used in conjunction with concrete and steel structures, covering scenarios such as roof panels and additional floors.
Manufacturers
Companies such as Beijing Yishi Zhuye Technology Development Co., Ltd. and Beijing Tianji New Materials Co., Ltd. supply related products, including steel frame lightweight roof panels and grid panels, meeting the diverse needs of steel structure factory building roofs.
