- Sheet Piles
The steel sheet piles of Nippon Steel are used in many fields (port and harbor structures, river revetments, retaining walls and cofferdams) and have acquired high market acceptance due to their excellent product quality and construction efficiencies that derive from their use.
- U-type sheet pilesPorts and rivers
-
- 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 ㎤/m to 3,820 ㎤/m.
- Hat-type sheet pilesPorts and rivers
-
Hat-type sheet pile is 900mm in width.- Superb drivability：The large sectional area of the Hat-Type sheet pile realizes superior drivability.
- High structural reliability：No reductioon 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,resulring in improved total cost.
- Hat-type and H-shape combined high stiffnes steel sheet pilesPorts and rivers
-
- Availability of numerous sectional properties：Hat-type and H-shape combined high stiffness steel sheet piles come in combination of Hat-type sheet piles which have four types and H-shape sections which have many types.Eventually they provide more than 200 types of economical properties(Section modulus per meter of wall:Approx.2,320 to 19,970㎤/m)
- Ease of Installation：An ordinary vivratory hammer is directly applicable for driving.The Hat-type and H-shape combined high stiffness steel sheet pile,having higher moment of inertia per pile compared with Z-type and other type piles,is very easy to work with.
- Straight web-type sheet pilesPorts and rivers
-
- High joint strength：This type of sheet pile boasts extremely high tensile strength at its interlocking sections,up to 5.88MN per linear meter of joint length,and is suited for use in celluar-type structures,such as quay walls,manmade island seawalls,cofferdams,and other similar projects.In addition,we can provide the longest product currently possible :a maximum of 38.0m.
- Large deviation angle：This sheet pile has large deviation angle at interlocks(the interlock swing),the maximum angles for the combination of the identical types of straight web-type sheet piles are respectively 10.0 and 12.5.
- Steel pile cell-type ship collision prevention facilityMain tower foundation
-
To build a steel sheet pile cell, linear steel sheet pile is connected in a circle and they are buried deep into the ground. Then, the steel sheet pile wall closed in a circle is filled with soil. Since it is buried deep in the ground and tightly filled with soil and it has a gravity structure with large diameter, energy absorption capability is much higher compared to the pile type. It is used as a ship collision prevention facility in ocean areas where large tankers cruise.
