Standard length and type of steel sheet pile

Steel sheet piles are widely used in foundation construction, port engineering, riverbank protection, and other infrastructure projects due to their excellent load-bearing capacity and soil-retaining properties. However, selecting the right steel sheet pile requires careful consideration of standard lengths and types, as different conditions demand different specifications.

So, what are the common standard lengths of steel sheet piles? What are the key differences between various types? This article will guide you through the essential details to help you make an informed choice.

Common Type of Steel Sheet Pile

Steel sheet piles come in various profiles, each designed for specific applications and soil conditions. The most common types include:

1. U-Type Steel Sheet Piles

Features: Traditional design with interlocking edges on both sides.

Common Sizes: Widths from 400mm to 750mm, thicknesses from 6mm to 20mm.

Applications: Riverbanks, retaining walls, underground structures.

2. Z-Type Steel Sheet Piles

Features: Continuous wall with higher bending resistance due to wider cross-section.

Common Sizes: Widths from 580mm to 770mm, thicknesses from 5mm to 16mm.

Applications: Deep excavation support, marine and harbor structures.

3. Straight-Web (Flat) Sheet Piles

Features: Flat design without deep interlocks, offering lower bending resistance.

Common Sizes: Widths from 400mm to 600mm, thicknesses from 8mm to 12mm.

Applications: Cut-off walls, groundwater control, temporary barriers.

4. Box-Type Sheet Piles

Features: Created by welding two U-type piles together for greater strength.

Applications: Heavy-duty retaining walls and large infrastructure projects.

Standard Length of Sheet Pile

The standard length of steel sheet piles varies depending on the manufacturer, region, and specific project requirements. However, common standard lengths include:

6 meters (20 feet)

9 meters (30 feet)

12 meters (40 feet)

15 meters (50 feet)

Manufacturers often provide custom lengths based on project needs, and steel sheet piles can be cut or welded to achieve the required dimensions. Additionally, different standards such as ASTM A572, JIS A 5528, EN 10248, and BS EN 10249 influence the dimensions and properties of steel sheet piles.

Customization & Special Treatments

Hot-rolled vs. Cold-formed: Hot-rolled sheet piles have higher structural strength, while cold-formed ones offer cost savings.

Coating & Corrosion Protection: Galvanization, epoxy coatings, and cathodic protection extend service life in marine environments.
