Steel sheet pile products are divided into two types according to production technology: cold-formed thin-walled steel sheet piles and hot-rolled steel sheet piles.

(1) Cold-formed steel sheet piles include non-bite type cold-formed steel sheet piles (also called channel plates) and bite-type cold-formed steel sheet piles (divided into L-type, S-type, U-type, and Z-type) . Production process: Thin plates (commonly used thickness 8mm ~ 14mm) are continuously rolled and formed in a cold bending unit. Advantages: less investment in production lines, lower production costs, and flexible product length control.

(2) Hot-rolled steel sheet piles. Hot-rolled steel sheet piles in the world mainly include U-type, Z-type, AS-type, H-type and dozens of specifications. The production, processing and installation processes of Z-shaped and AS-shaped steel sheet piles are relatively complex and are mainly used in Europe and the United States; in China, U-shaped steel sheet piles are mainly used. Production process: It is formed by high-temperature rolling in a section steel rolling mill. Advantages: standardized size, superior performance, reasonable cross-section, high quality, and tight water-proof lock bite.

In engineering construction, cold-formed steel sheet piles have a narrow application range and are mostly used as supplementary materials. Hot-rolled steel sheet piles have always been the leading product in engineering applications.
