Explanation of the difference between steel space frame and steel roof frame

Steel space frame and steel roof frame are constructed on the building, but the two structural forms are different. Steel space frame is usually composed of horizontal and vertical steel bars, shaped like a rectangular grid, their intersection welded. Steel roof frames, on the other hand, are made up of multiple columns and beams, and their overall shape is similar to a trapezoidal or fan-shaped.

Second, the difference in the scope of application

The use of steel mesh racking is relatively narrow, applicable to the roof of the storage room, machine room, garage and other buildings, while the use of steel roof racking is much wider, applicable to factories, commercial markets, public buildings and other large-scale building roofs.

 

Third, the construction process of different

Steel space frame construction process is relatively simple, mainly on the ground, will be assembled into a grid of steel billet, and then processed and turned, and finally installed on the building. The construction process of steel roof frame is more complex, each column and beam need to be accurate processing and adjustment, in order to achieve stability and meet the design requirements of the effect. Second, the scope of application of the different

Steel space frame is relatively narrow, applicable to the storage room, machine room, garage and other buildings of the roof, while the scope of use of steel roofing is more extensive, applicable to factories, commercial markets, public buildings and other large-scale buildings of the roof.

 

Fourth, the other differences

In addition to the above differences, steel wire space frame and steel roof frame also have the following differences:

1.Different materials used: the material of steel space frame is generally ordinary low carbon steel, while steel roof frame uses high strength steel.

2.Different installation methods: the installation of steel space frame needs to use expansion bolts to connect it with the building, while the steel roof frame is generally installed using the welding method.
