Steel Sheet Pile

Hat-type sheet piles

• 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.

U-type sheet piles

• U-type sections have been widely used for various types of permanent and temporary structures, and are one of the most familiar sheet piles among both designers and users.
• 
  NS-SP-Ⅱ,Ⅲ,ⅢA,Ⅳ,ⅤL and ⅥL are solidly designed. These sections are especially suitable for repeated use, and have acquired high market acceptance from users.
• 
  U-type sections offer section modulus ranging from 874 cm3/m to 3,820 cm3/m.

Corner-section Sheet Piles: As Rolls

High reliability

• Corner-section sheet piles are a newly developed type produced by rolling, to replace the conventional T-shape corner-sheet piles produced by welding. Thus, these eliminate the need for welding and other fabrication processes and are far lighter in weight.
• For assembly, the conventional cast equipment can be used as-is.
• In particular, Larssen sheet piling has been adopted as a base for the shape of corner joints, in order to prevent detachment, and therefore, particularly, joint performance such as fitment and repetition endurance is excellent.

U-type sheet piles

• Close-proximity installation
  NS-SP-J piles can be installed in close proximity to existing structures, permitting the construction of retaining walls abutting site boundaries and making maximum use of the site area.
• 
  100% intelock integrity
  As interlocks are located on the outermost side of the wall, there is no need to consider the reduction of sectional properties due to slip on interlocks, and this permits economical design.
• 
  Cost-saving and Work-shortening of Temporary Work
  Cost-saving and the shortening of temporary work time Compared to conventional steel sheet piles for temporary work with an effective width of 400 mm, NS-SP-J has an effective width of 600 mm. This makes it possible to reduce the number of installed piles, with less cost and improved water tightness.
