Omega Type (Hat / Pan) Steel Sheet Piles
Omega type sheet piles (also known as hat type, pan type, L type, or S type sheet piles) are cold formed steel sections with a hat-shaped cross-section. Their relatively thin thickness combined with wider sectional geometry enables efficient pile driving, reliable structural performance, and cost-effective solutions for light-duty retaining structures.
Manufacturing & Structural Characteristics
Omega type sheet piles are produced using cold forming technology, where steel plates are shaped through continuous rolling processes.
- Uniform thickness along the entire profile
- Hat-shaped cross section with larger effective width
- Interlocks located at the outermost edges of the section
- Neutral axis of each pile aligns with the overall wall system
👉 Engineering Insight：
Because the neutral axis aligns with the wall system, Omega (L/S type) sheet piles can maintain stable structural performance across various soil conditions while improving deformation control during installation.
Product Characteristics
- Thin gauge design (starting from approx. 3mm)
- Larger sectional width compared to U/Z types
- Lightweight and easy handling
- High rigidity → better deformation control
- Capable of long-length driving
👉 Key Benefit：
Efficient driving performance with smaller equipment such as light hammers or compact rigs.
Naming & Market Classification
Omega sheet piles are known by different names globally:
- USA → Pan Type Sheet Pile
- Japan / Korea → Hat Type Sheet Pile
- Europe → L Type / S Type Sheet Pile
- Asia / China → Omega Type Sheet Pile
👉 Originally developed by Oriental Sheet Pile, widely used in Asia and increasingly adopted in other regions.
Engineering Application Scope
Omega (hat type) sheet piles are primarily used for:
- Drainage ditches
- Small retaining walls (residential / private projects)
- Golf course structures
- River bank protection (limited space conditions)
- Deadman walls / Anchored wall systems
👉 Design Positioning：
Light-duty retaining structures with economic efficiency as priority.
