Trough shaped steel sheet pile is a cold-formed buckle type thin-walled steel sheet pile with a groove shaped cross-section, which has high bending resistance, shear torsion stiffness, and stability. Trough shaped steel sheet pile is a foundation steel composed of steel plates, with the characteristic of a groove shaped cross-section. It can be formed as a steel sheet pile for foundation pit support structure by overlapping or side by side.

As a sturdy guardian in modern engineering, steel sheet piles play an important role in various construction projects due to their advantages such as high strength, easy construction, and good waterproof performance. Steel sheet piles, as a steel structure with linkage devices at the edges and can be freely combined, play a crucial role in the engineering field. Due to their high strength, easy construction, and superior waterproof performance, they are widely used in various construction projects.
