Precast panels are large, factory-made concrete sections used in construction. They are produced in controlled environments, allowing for consistent quality and faster assembly on-site. These panels can be designed for walls, floors, or facades, making them versatile for various building types. The use of precast panels offers several advantages, including reduced construction time and lower labor costs. They are also durable and can be designed to meet specific insulation and aesthetic requirements. This makes them a popular choice for commercial, industrial, and residential projects.
