Tanzania 25*40 Steel Structure Cement Production Workshop
Steel buildings are becoming more and more popular in the construction industry. It is widely used as commercial shop buildings, warehouse, workshop, storage buildings, and logistics bases. The advantages of steel buildings include their durability, low cost compared to conventional construction, and the fact that they take much less time to build than other types of new construction.
The main steel frame structure consists of welded H-section steel columns and beams connected by high-strength bolts. All steel structure components are welded in our factory with CNC machines. We design various structures including single span, double span, portal frame, or truss roof systems.
