Hat-Type Sheet Pile 900 was developed as a new generation sheet pile with improved drivability, higher structural reliability, and more economical merit compared with traditional U type sheet piles. Hat-Type Sheet Pile 900 which has thin and large section shape of 900mm in effective width has been developed on the basis of state-of- the-art rolling technology and design/construction know-how, and has been commercially available since 2005.

The Hat-Type Sheet Pile 900 is a structural steel product that incorporates the essence of sheet pile manufacturing technology and application technology relating to design and construction work. Its application extends beyond conventional civil engineering works, such as river revetments and port piers. It can also be applied to road retaining walls and stress insulating walls, waterway walls, watertightening walls, etc. as measures to prevent ground subsidence.

• Superb drivability The large sectional area of the Hat-type sheet pile realizes superior drivability.
• High structural reliability No reduction is required in sectional properties to consider the possible lack of shear force transmission at the interlocks, which is true for U-type steel sheet piles.
• Excellent cost-effectiveness The amount of steel per unit wall can be reduced, resulting in improved total cost
