The prestressed steel structure uses special methods to get the corresponding function on the steel structure by pre stressing the stress. The prestressed steel structure can save more steel and better stability when used. It is mainly divided into four types: traditional structure type, suspended structure type, integral tension type and tension metal film type. 1. traditional structure type It is composed of two groups of cables, bearing cables and stabilizing cables, which can improve stiffness. 2. hanger structure type It is composed of sling, vertical support and roof, which can reduce deflection. 3. integral tension type It can make the whole roof structure more lightweight and novel in design. 4. tension metal film type Easy to maintain, the load-bearing performance is better. Foshan steel structure Sheng Bang believes that choosing the right steel structure will make the steel structure play a greater role.
