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, durability, thermal insulation, heat insulation, waterproofing, fire resistance, sound insulation, explosion venting, and seismic resistance. The panel 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 safety and durability of the structure. The product range is comprehensive, installation is quick, and maintenance is simple. The product is mainly suitable for roof applications in buildings such as railway transportation, industrial workshops, warehousing logistics, large public buildings, and sports venues. It can be matched with various structural forms such as concrete structures, lightweight steel structures, and spatial grid structures, with a wide range of applications.
