The cold-formed steel sheet pile is continuously rolled and formed by the cold-formed machine, and the side locks can be continuously lapped to form a steel structure of the sheet pile wall. Cold-formed steel sheet piles are made of thinner plates (commonly used with a thickness of 8mm to 14mm) and processed by cold-formed forming machines. Its production cost is low and the price is cheap, and the sizing control is also more flexible.
However, due to the simple processing method, the thickness of each part of the pile body is the same, and the cross-sectional size cannot be optimized, resulting in an increase in steel consumption; the shape of the locking part is difficult to control, and the buckle at the joint is not tight, and it is impossible to stop water; restricted by the capacity of cold bending processing equipment, only It can produce products with low steel strength and thin thickness;
Moreover, the stress generated during the cold bending process is relatively large, and the pile body is prone to tearing during use, so the application has relatively large limitations. In engineering construction, the application range of cold-formed steel sheet piles is relatively narrow, and most of them are only used as supplementary materials.
Features of cold-formed steel sheet piles: According to the actual situation of the project, the most economical and reasonable section can be selected to achieve the optimization of engineering design. Compared with the hot-rolled steel sheet piles with the same performance, the materials can be saved by 10-15%, which greatly reduces the construction cost.
