[0006] Steel structure house components, the main structure uses lightweight materials such as iron sheets as walls, roofs or floors. Most of them are temporary buildings, usually connected by bolts or welding. They are easy to construct and have good working conditions, but there are weak links such as anti-corrosion, sound insulation, heat insulation, and waterproofing, resulting in poor living comfort and durability.
