The steel frame skeleton lightweight board 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. It inherits the reliability of traditional reinforced concrete roof panels and absorbs the advantages of other lightweight boards. 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 board is mainly suitable for roofs of buildings such as rail transit, industrial workshops, 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, and has a wide range of applications.
