What is Steel Sheet Pile?
Steel sheet piles are a type of steel sections with a vertical interlocking system, common shapes are u, z and flat web. Hot rolled steel sheet piles can be used for deep foundation pits, high water pressure, complex geology, permanent structures, or projects with strict requirements for water stopping and safety, cold formed steel sheet piles are an economical, lightweight, and temporary solution for shallow foundations, small trenches, temporary enclosures, low water-stopping requirements, and tight budgets.
Steel sheet pile working principle: A group of steel sheet piles are interconnected through the interlocking joints to form a continuous, solid retaining steel sheet pile wall. Customized steel sheet pile systems are developed for various applications for earth and water retaining, the main applications are projects such as foundation pit support, embankments, docks, and cofferdams.

Hot Rolled Steel Sheet Pile Manufacturing Capacity
AGICO has a rich history of exporting profiles and hot rolled steel sheet piles. We have supply factory of a leading domestic production base for ultra-large specialized steel sheet piles. Equipped with the world’s largest continuous steel rolling mill, the steel mill primarily produces large Z-shaped steel sheet pile, U-shaped steel sheet pile and flat web sheet pile, corner sheet pile, as well as H-shaped pile, and other world-leading ultra-large specialized steel profiles.
These products are widely used in key domestic and international projects, including railways, ships, bridges, offshore drilling platforms, and large-scale specialized facilities. In 2016, the factory successfully trial-rolled Asia’s first hot-rolled European-standard Z-shaped steel sheet pile and began mass production, breaking the European and American monopoly on the global market and ending Asia’s historical inability to produce hot-rolled Z-shaped steel sheet piles. This marked the AGICO achievement of the technology and capabilities to produce world-class ultra-large specialized profiles.

Hot Rolled Steel Sheet Pile Manufacturing Process
1. Steel Smelting
Steel Smelting: Our hot-rolled steel sheet pile production line utilizes advanced technology throughout the entire process, ensuring steel sheet pile strength and reliability from raw material. Steel Smelting begins with steelmaking in a blast furnace or electric arc furnace. Refining treatments in converters, LF furnaces, and VD furnaces effectively remove impurities and enhance purity, ensuring exceptional steel quality. The steel billets are then formed in a continuous billet caster. After uniform heating in a heating furnace, they enter the rolling stage.
2. Hot-Rolling
Hot-Rolling Process: During the hot-rolling stage, the steel billets pass through a roughing mill and a high-pressure water descaling system before entering the 9-stand universal rolling mill, where they are formed into precise sheet pile cross-sections. After hot-rolling, the steel sheet piles are cut using hot saws, then pre-bent and cooled, and then horizontally and vertically straightened to ensure dimensional accuracy and shape stability. The last step is drilling, milling. After final inspection for quality control, the final product is ready for stock or delivery.
Tips for Choosing the Right Sheet Pile Type for Your Project
- Project requirements: Excavation depth and shape, soil conditions (earth pressure, water pressure), water-stopping requirements, surrounding environment (whether buildings or pipelines require protection), and design allowable deformation.
- Steel Sheet Pile performance: Focus on section modulus (bending resistance), moment of inertia (deformation resistance), and weight per meter (which correlates with cost and construction difficulty). These parameters must be determined through rigorous structural calculations.
- Construction conditions: Existing piling equipment capacity, construction space, and construction schedule requirements.
- Economic and environmental considerations: Consider the one-time investment, reusability (rental or recycling), and overall cost. Hot-rolled steel sheet piles are reusable and are a green, low-carbon building material.
| Type | Structural Features | Primary Applications |
|---|---|---|
| U-Type (Larssen) | U-shaped profile with interlocks on both sides; can be used singly or in pairs. Advantage: Simple installation; good watertightness at interlocks; high recyclability for temporary works. | Municipal excavations; temporary cofferdams; utility corridors; urban retaining walls. |
| Z-Type (AZ Series) | Z-shaped profile with interlocks set away from the neutral axis. | Ports and quay walls; deep excavations; river/shoreline protection; flood defenses. |
| Flat Web | Flat web; often installed in pairs to form a box-like section; compatible with pipe/H-pile king piles. Advantage: Very large moment of inertia; high overall stiffness; suitable for heavy-duty, permanent structures. | Large cofferdams; dry docks and heavy quay structures; bridge abutments and foundations. |
| FSP | Narrower profiles common in JP/APAC catalogs; robust interlocks. | Water conservancy projects; deep excavations; structural strengthening in tough conditions. |
| PU | Lighter profiles for small to medium works. Advantage: Lower weight and cost; flexible handling; suitable where loads are moderate. | Small/medium excavations; temporary cofferdams; urban canals and revetments. |
