ALC (Autoclaved Lightweight Concrete) wall panel is a high-performance precast building material made from cement, lime, silica sand, aluminum powder, and reinforced steel mesh, cured under high-temperature and high-pressure steam. It has become a preferred wall solution for residential, commercial, industrial, and public buildings due to its all-around performance.
First, lightweight & high strength: ALC panel is about 1/4 the weight of traditional concrete, greatly reducing building deadweight and foundation costs while maintaining reliable structural strength and seismic performance. Second, excellent fire resistance: as an inorganic non-combustible material, 100mm–150mm panels reach A-class fire rating with fire resistance up to 4 hours, protecting structure and safety. Third, sound & thermal insulation: its porous internal structure delivers stable sound insulation and low thermal conductivity, cutting energy consumption for heating and cooling. Fourth, eco-friendly & dry construction: low waste, no harmful emissions, compatible with dry installation to shorten construction period and reduce wet work.
ALC wall panels fit interior partitions, external walls, fire barriers, and wet-area walls. They integrate multiple functions and support prefabricated and green building goals, making them an ideal choice for modern construction.
