Steel sheet pile products are divided into cold-formed thin-walled steel sheet piles and hot-rolled steel sheet piles according to production technology. There are two types of cold-formed steel sheet piles: non-occluded cold-formed steel sheet piles (also known as trough plates) and occluded cold-formed steel sheet piles (divided into L-type, S-type, U-type and Z-type). Production technology: continuous rolling of thin steel plate (commonly used thickness is 8mm~ 14mm) on a cold bending unit.
U-shaped steel sheet pile is easy to drive into hard soil layer; Construction can be carried out in deep water, and if necessary, diagonal braces can be added to form a cage. Good waterproof performance; Cofferdams with various shapes can be formed according to needs and can be reused for many times.
