Some of the applications requiring steel sheet piling as stiff and flexible retaining wall are:

1. Waterfront structures

Steel sheet piling is suitable for offshore construction as it is designed to cater for heavy vertical loads and large bending moments with fast execution. Few types of retaining structures in waterfront structures are ship berthing area, wharf, breakwater and slipway.

2. Canalization

Steel sheet piling is used as the support, protection and beautification of river embankments. It can also function as flood protection wall during monsoon or high-tide season.

3. Basement

Steel sheet piling can be used for top down construction (permanent) or bottom up construction (temporary); both methods require minimal construction width offering significant time and cost savings. Steel sheet pile can also support vertical loads from the structure above.

4. Railway and Tunnel

As support structure for railway and tunnel construction, steel sheet piling helps to minimize excavation and disposal works, thus speed up the construction duration.

5. General Excavation

General excavation works involve temporary excavation for foundation construction and protection to underground structure, minimizing excavation volume and area.

6. Highway Construction

Most of the time, steel sheet piles act as retaining structure for excavation works. They can be installed easily and extracted anytime when the construction work is completed. The steel sheet piles can then be re-used and carried forward for later construction stages.

7. Bridge

Steel sheet piles can act as foundation and abutment of the bridge, requiring minimum space and construction time.

Types：

Z Section

Continuous form of the web and location of the interlock symmetrically on each side of the neutral axis provides positive influence on the section modulus on the Z section.

U Section

Symmetrical form of the single element made U section convenient for re-use or even applied as permanent solution.

OΩ Section
