The steel frame skeleton lightweight roof panel is a new type of lightweight roof-bearing inorganic panel that integrates functions such as light weight, load-bearing, durability, thermal insulation, heat insulation, waterproofing, fireproofing, noise insulation, explosion venting, and seismic resistance. It inherits the reliability of traditional reinforced concrete roof panels and absorbs the advantages of other lightweight panels. While achieving light weight and multifunctionality, it highlights the structural safety and durability. The product range is comprehensive, installation is quick, and maintenance is simple. The product is mainly suitable for roof applications in buildings such as rail transit, industrial factories, warehousing and logistics, large public buildings, and sports venues. It can be matched with various structural forms such as concrete structures, light steel structures, and spatial grid structures, and has a wide range of applications.
