The steel frame skeletal lightweight board is a new type of inorganic load-bearing roof panel that integrates lightweight, load-bearing, durable, thermal insulation, heat insulation, waterproofing, fireproofing, noise insulation, explosion relief, and seismic resistance. It inherits the reliability of traditional reinforced concrete roof panels and absorbs the advantages of other lightweight boards. While achieving lightness and multifunctionality, it highlights the structural safety and durability. The product range is comprehensive, installation is quick, and maintenance is simple. The board is primarily suitable for roofs of buildings such as rail transit, industrial workshops, warehousing and logistics, large public buildings, and sports venues. It can be matched with various structural forms like concrete structures, light steel structures, and spatial trusses, making its application versatile.
