Steel Sheets Piles - Royal Steel Group
Steel sheet piles constitute the building blocks of earth-retaining systems such as waterfront bulkheads, cofferdams, seawalls and levees. They provide strength, stability, and water-tightness to construction projects for civil engineering, marine and industrial applications.
Hot-Rolled Sheet Piles
Produced at high temperature above recrystallization point.
High toughness, good ductility, large thickness options.
Ideal for heavy-duty permanent structures and marine applications.
Cold-Rolled Sheet Piles
Produced at room temperature for precise dimensions and smooth surfaces.
Moderate strength, high dimensional accuracy.
Suitable for temporary structures or lightweight walls requiring fast installation.

Larssen Sheet Piles
Larssen Sheet Piles are the most widely used hot-rolled U-type steel sheet piles globally. Named after the classic Larssen interlock design, these piles are valued for their superior mechanical performance, water-tight sealing, and excellent reusability. They are core materials in foundation support, flood control, marine engineering, and river management projects.
Type Ⅱ (Type 2) steel sheet piles and Type Ⅳ (Type 4) steel sheet piles are the two most commonly used U-shaped hot-rolled steel sheet pile models among Larssen Sheet Piles. The numerical designations represent an increasing sequence of their cross-sectional dimensions, weight, and load-bearing capacity, and they are widely used in various foundation pit supports, seepage prevention and soil retaining, as well as hydraulic engineering projects.
| Parameter | Type Ⅱ (SP-Ⅱ) | Type Ⅳ (SP-Ⅳ) | Key Differences |
| Width (mm) | 400 | 400 | Same width for easy splicing and connection |
| Height (mm) | 100 | 170 | Type Ⅳ features a 70% increase in section height, which improves the section modulus |
| Thickness (mm) | 10.5 | 15.5 | Type Ⅳ has a 47.6% increase in thickness, enhancing overall structural strength |
| Unit Weight (kg/m) | Approx. 61.2 | Approx. 76.1 | Type Ⅳ boasts a 24.3% weight increase, delivering stronger load-bearing capacity |
| Section Modulus (m³/m) | Approx. 0.000874 | Approx. 0.00134 | Type Ⅳ realizes a 53.3% improvement in bending stiffness |
| Interlock Type | Larssen Standard Interlock | Larssen Standard Interlock | Both adopt high-waterproof performance tongue-and-groove interlocks |
