The application of MS plate in prefabricated construction promotes the development of efficient, green, and standardized building systems. Prefabricated components made of MS plate are processed in factories with high precision and then assembled on site, significantly improving construction efficiency and reducing labor costs. Excellent formability and weldability allow the production of standardized beams, columns, wall panels, and floor slabs, meeting modular design requirements. High structural strength and stability ensure the safety and durability of prefabricated buildings, suitable for residential, commercial, industrial, and public construction projects. Light weight compared with concrete structures reduces foundation load and transportation costs, supporting sustainable building development. MS plate can be recycled and reused at the end of building service life, in line with green environmental protection concepts. Tianjin Gaosteel Group's MS plate has stable mechanical properties and precise dimensional tolerance, adapting to automated prefabricated production lines.
