Steel Space Frame Installation

Steel Structure Factory Building

Structural components can be prefabricated in the factory with high precision and high production efficiency. After being transported to the site, they only need to be simply assembled, which can greatly shorten the construction period. Compared with traditional concrete structure plants, they can be built and put into production faster, reducing the time occupied by investment costs. Efficient space utilization: The cross-section of steel structure columns is relatively small, which can provide a wider indoor space, facilitate the layout of large-scale production equipment and complex process flows in heavy industrial plants, and also facilitate the installation, commissioning and operation of large equipment, improving the convenience of production operations and space utilization. High design flexibility: Steel has good plasticity and processability. It can be flexibly customized according to the needs of different heavy industrial production processes and processes. It can also achieve large-span design, reduce the number of columns and beams, and provide spacious space for production. Good durability: The steel frame can be made of super anti-corrosion high-strength cold-rolled galvanized sheet, which can effectively avoid the rust problem of steel plates during construction and use, and increase the service life of light steel components. Under normal maintenance, the life of the steel structure plant can reach 100 years, and it is easy to repair, only regular simple maintenance is required.
