Cold-formed steel sheet piles

High Strength and Durability – Steel sheet piles are designed with strong interlocking edges, allowing them to be easily driven into hard soil layers and providing excellent stability for demanding construction environments.
Adaptability in Construction – They can be installed even in deep water, and when combined with inclined supports, they form reinforced cage-like structures suitable for complex engineering projects.
Excellent Waterproofing Performance – With tightly connected joints, steel sheet piles offer reliable water resistance, making them ideal for cofferdams, retaining walls, and other structures requiring water isolation.
Reusability and Flexible Design – Available in various cross-sectional shapes such as straight, groove, and Z-types, they can be assembled into different configurations and reused multiple times, ensuring both versatility and cost-effectiveness.

Product Details

A steel sheet pile is a steel structure with linkages on the edges, and the linkages can be freely combined to form a continuous and tight retaining wall or a steel structure. Its cross-section has straight plate, groove and Z shape, etc., with various sizes and interlocking forms. The common ones are Larson, Lackawanna and so on. Its advantages are: high strength, easy to drive into the hard soil layer; can be constructed in deep water, if necessary, add inclined support to become a cage. Good waterproof performance; can form cofferdams of various shapes as required, and can be reused many times, so it is widely used.

Classification of sheet piles

Steel sheet pile products are divided into cold-formed thin-walled steel sheet piles and hot-rolled steel sheet piles according to the production process.

(1) Cold-formed steel sheet piles continuously cold-bend the steel strip to form Z-shaped, U-shaped or other shapes of cross-section, which can be connected to each other through locks. There are two types of 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, Z-type). Production process: The thin plate (commonly used thickness 8mm ~ 14mm) is continuously rolled and formed in the cold bending unit. Advantages: less investment in production lines, lower production costs, and flexible product sizing control. Disadvantages: The thickness of each part of the pile body is the same, the section size cannot be optimized, resulting in an increase in the amount of steel used, the shape of the locking part is difficult to control, the joints are not tightly buckled, and the water cannot be stopped, and the pile body is prone to tearing during use.

(2) The hot-rolled steel sheet pile has a tight water barrier with its lock bite. The world's hot-rolled steel sheet piles mainly include U-type, Z-type, AS-type, H-type and dozens of specifications. Production process: It is formed by high temperature rolling in a section steel rolling mill. Advantages: standard size, superior performance, reasonable cross-section, high quality, and tight water-resistance for locking. Disadvantages: technical difficulty, high production cost, inflexible specification series.
