Cold-formed steel sheet piles are made from thinner sheets (commonly 8mm to 14mm thick) using a cold-bending machine. They offer low production costs, low prices, and more flexible length control.

However, due to the crude processing method, the thickness of each part of the sheet pile body is uniform, making it impossible to optimize cross-sectional dimensions, resulting in increased steel consumption. The shape of the locking joints is difficult to control, resulting in loose joints and inability to seal water.

Limited by the capacity of cold-bending equipment, only low-strength steel grades and thin thicknesses can be produced. Furthermore, the high stress generated during the cold-bending process can easily cause the sheet pile body to tear during use, significantly limiting its application.
