The steel frame skeletal lightweight roof panel is a new type of lightweight roof load-bearing inorganic board that integrates functions such as light weight, load-bearing capacity, durability, thermal insulation, heat insulation, waterproofing, fireproofing, sound insulation, explosion venting, and seismic resistance. This board inherits the reliability of traditional reinforced concrete roof panels and absorbs the advantages of other lightweight boards. While achieving light weight and multifunctionality, it emphasizes 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 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, with a wide range of applications.
