Steel pipe is not only used for conveying fluid and powdery solid, exchanging heat energy, manufacturing mechanical parts and containers, but also an economic steel. Using steel pipe to manufacture building structure grid, pillar and mechanical support can reduce the weight, save 20-40% of metal, and realize factory mechanized construction. Manufacturing Highway Bridges with steel pipes can not only save steel and simplify construction, but also greatly reduce the area of protective coating and save investment and maintenance costs.
