Customized Prefabricated Hot Dip Galvanized Steel Frame Buildings
1, The cost is much lower than that of concrete structures, and our steel structure has a high repurchase rate.
2, Prefabricated building, the workload is small, the customer only needs to use bolts to assemble the components, and the construction speed is fast.
3, The structure is firm and the ductility is good. It is designed according to the load and can be designed to have anti-seismic and wind-resistant properties.
1. The tensile strength of steel is much more times greater than concrete.
2. Steel is also ductile in nature.
3. Steel has also the high strength to weight ratio as compared to concrete.
4. Steel structures are also preferred when time span is small. Construction rate is very fast.
5. Steel bars are also reusable.
6. Steel structures can be extended in any direction.
Qingdao Ruly Steel Engineering Co.,Ltd is a professional steel structure fabrication and construction company for light and heavy steel structure project. Our service include design, fabrication for all the steel structure components and insullation panel, installation on site.
