Standards, Sizes, Production Processes and Applications of U type steel sheet piles-Royal Steel

Steel Sheet piles are structural profiles with interlocking edges that are driven into the ground to form a continuous wall. Sheet piling can be used in both temporary and permanent construction projects to retain soil, water, and other materials.

2. Sizes for U-type Steel Sheet Piles

U-type sheet piles come in different profiles depending on bending moment resistance, interlock type, and section modulus. Typical ranges:

Length: 6–18 m (customized up to 24 m or more)
Thickness: 6–16 mm
Width (effective): 400–750 mm per pile
Height (depth): 100–380 mm
Section Modulus (Wx): ~400 – 4000 cm³/m
Moment of Inertia (Ix): ~80,000 – 800,000 cm⁴/m
Weight: 40 – 120 kg/m² of wall (varies by profile)

3.Production processes for U-type Steel Sheet Piles

The manufacturing of U-type sheet piles mainly follows hot rolling or cold forming:

Hot Rolled U-type Sheet Piles

Process:

(1). Raw material: steel billet reheated in furnace (~1200 °C).
(2). Hot rolling through specialized sheet pile rolls to form U profile.
(3). Cooling, straightening, cutting to required lengths.
(4). Interlock finishing & inspection.
Features:

Higher strength and tighter interlocks.
Better water-tightness.
Heavier sections possible.
Common in Europe, Japan, and China.

Cold Formed U-type Sheet Piles

Process:

(1). Steel coils uncoiled and leveled.
(2). Cold bending/forming by a continuous roll-forming machine at room temperature.
(3). Cutting to required lengths.
Features:

More economical, flexible in length.
Wider section choices.
Slightly looser interlocks (less water-tight).
Common in North America and China.

Application

1. Ports and Water Conservancy Projects

Ports and Wharves: Used for wharf retaining walls, berth walls, and dock cofferdams.

Revetments and Breakwaters: Used to prevent scouring and landslides on coasts, riverbanks, and lakes.

Docks and Locks: Used as temporary or permanent soil/water retaining structures.

2. Foundation and Underground Engineering

Pit Support: Used for temporary or permanent support in excavation pits for subways, underground garages, tunnels, and pipeline corridors.

Retaining Walls: Support soil in soft soil layers or sites with uneven elevation.

Waterstop Curtains: Used in conjunction with grouting or sealing materials to prevent seepage in underground projects.

3. Flood Control and Emergency Engineering

Flood Control Dikes: Used for embankment reinforcement and river channel seepage control.

Emergency Engineering: Rapidly construct temporary protective walls in emergency situations such as floods and landslides.

4. Industrial and Energy Projects

Power Plants/Waterworks: Water retaining and revetment at cooling water inlets and outlets. Oil, Gas, and Chemical Facilities: Used for anti-seepage and foundation reinforcement of liquid storage tank foundations.

5. Transportation and Municipal Engineering

Bridge Engineering: Used for cofferdam support during bridge pier construction.

Roads and Railways: Used for retaining roadbed slopes and preventing landslides.

Urban Infrastructure: Used for temporary retaining walls during pipeline and subway construction.
