U-shaped Steel Sheet Pile

U-shaped steel sheet piles are hot-rolled or cold-formed steel sections with interlocking edges that connect adjacent piles to create a continuous retaining wall. Their symmetrical profile, interlocking design, and range of section sizes make them suitable for temporary and permanent earth-retaining structures, including cofferdams, excavation support, quay walls, and riverbank protection.

Materials and steel grades

Central Steel supplies U-shaped steel sheet piles, including Larssen-type sheet piles, in various steel grades to meet the requirements of excavation support, retaining walls, riverbank protection, and marine and foundation engineering projects.

Standard	Available steel grades
European standards (EN 10248 / EN 10249)	S240GP, S270GP, S320GP, S355GP, S390GP, S430GP
Japanese standards (JIS A 5528 / JIS A 5523)	SY295, SY390, SYW295, SYW390
American standards (ASTM)	ASTM A36, ASTM A572 Grade 50 / 60, ASTM A690
Chinese standards (GB/T)	Q235B, Q295P, Q345P, Q355B, Q390P, Q420P, Q460P

Key Advantages:

Broad Range of Profiles: Wide selection of section moduli (from 500 to over 4,000 cm³/m) catering to light temporary works and heavy permanent marine structures.

Symmetrical Geometry: Facilitates ease of handling, installation, and multiple re-use cycles.

High Bending Resistance: Optimized combination of wave depth and flange/web thickness delivers superior structural efficiency.

Custom Cut Lengths: Tailored length supply minimizes job site waste and accelerates driving operations.

Applications of U-shaped steel sheet piles

U-shaped steel sheet piles are used in a variety of civil engineering and foundation projects, including:

Cofferdams and temporary excavation support
Retaining walls for roads, railways, and construction sites
Riverbank and canal protection
Quay walls, docks, and port infrastructure
Flood-control and water-management structures
Temporary trench support and underground utility works

Ordering U-shaped steel sheet piles

To confirm the suitable profile and quotation, please provide the required section designation, material grade, length, quantity, applicable standard, surface protection requirements, and project application. Drawings or a project specification are recommended when structural section properties and dimensional tolerances are critical.
