As an excellent foundation support material, groove shaped steel sheet piles are widely used in fields such as natural gas, oil, ports, docks, airports, and urban construction. In construction engineering, groove shaped steel sheet piles are mainly used for foundation support of various types of land and underground buildings, retaining walls, water tanks, precipitation outlets, and other foundation projects. In addition, it is also used in multiple fields such as hydraulic engineering, transportation route buildings, waterway maintenance, civil engineering, and hydraulic engineering buildings.

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.
