Depending on their load-bearing characteristics and construction requirements, steel sheet piles are primarily classified into the following categories:
1. Z-shaped steel sheet piles
These have a Z-shaped cross-section, with interlocking joints located at the edges of the sheet piles. They offer excellent flexural strength and are particularly suitable for withstanding high lateral earth pressures. They are commonly used in permanent retaining structures and heavy-duty projects with high load-bearing requirements.
2. U-shaped steel sheet piles
With a U-shaped cross-section and interlocks situated near the neutral axis, these form a stable, symmetrical wall when assembled. This type of steel sheet pile is widely used, being suitable for both temporary shoring and permanent structures.
3. Straight-web (Flat) Steel Sheet Piles
These have a relatively straight or slightly curved cross-section and are fitted with high-strength interlocks. They are primarily used in circular or cellular structures, where overall stability relies more on the structural geometry and the tensile forces between the interlocks than on pure bending resistance.
4. Combi Wall System
Comprising large-diameter main piles and steel sheet pile infill panels, this system offers extremely high overall rigidity and load-bearing capacity. It is frequently used in port and marine engineering projects where conditions are complex and structural requirements are stringent.
