Prefabricated components are building parts that are manufactured in a factory before being transported to a construction site. These components can include walls, floors, and roofs, which are made to specific measurements and designs. This method allows for quicker assembly and often reduces construction waste. Using prefabricated components can lead to cost savings and improved quality control, as they are produced in a controlled environment. This approach is commonly used in various construction projects, including residential homes and commercial buildings, making the building process more efficient and streamlined.
