The steel frame skeletal lightweight roof panel is a new type of lightweight roof-bearing inorganic panel that integrates functions such as lightness, load-bearing capacity, durability, thermal insulation, heat insulation, waterproofing, fire resistance, noise insulation, explosion relief, and seismic resistance. This panel inherits the reliability of traditional reinforced concrete roof panels while absorbing the advantages of other lightweight panels. It emphasizes both lightness and multifunctionality while highlighting 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, lightweight steel structures, and spatial grid structures, with a wide range of applications.
