Hat-Type Sheet Piling Adopted for Construction of Retaining wall for Mass Rapid Transit System (MRT)

Steel Sheet Pile is an effective earth retention and excavation support construction material, Used worldwide for the construction of quays walls and breakwaters in harbours, locks, and for bank reinforcement on rivers and canals. The Interlocking Sheet Piles also offer considerable resistance against water seepage.

FAMOUS has one of the widest ranges of steel sheet piles for sale: with over 15 series' and over 400 profiles in hot rolled sheet piles, cold rolled sheet piles and cold formed sheet piles in assortment of steel grades and production standards.
Applications include port and harbour structures, river revetments, retaining walls, cutoff walls, slope protection and cofferdams.

Hot Rolled Sheet Piles
Hot Rolled Sheet Piles are formed by profiling the steel with high temperatures as the rolling process occurs. Typically, hot rolled sheet piles are produced to BS EN 10248 Part 1 & 2. Greater thicknesses are achievable than cold rolled sheet piles. The interlocking clutch tends to be tighter as well.

Cold Formed & Cold Rolled Sheet Piles
Cold Rolling and Forming processes are when the steel sheet pile is profiled at room temperature. The profile thickness is constant along the width of the profile. Typically, cold rolled/formed sheet piles are produced to BS EN 10249 Part 1 & 2. Cold Rolling occurs in a continuous section from hot rolled coil whereas Cold Forming occurs is discrete lengths either from decoiled hot rolled coil or plate. A wide range of widths and depths are achievable.

Types

Steel sheet piling is manufactured in three basic configurations: “Z”, “U” and “straight” (flat). Historically, such shapes have been hot-rolled products produced at structural mills. Like other shapes such as beams or channels, the steel is heated in a furnace and then passes through a series of rolls to form the final shape and the interlock, which allows the sheet piles to be threaded together. Some use a cold-forming process in which steel coil is rolled at room temperature into the final sheet pile shape. Cold formed sheet piles have hook and grip interlocks.

Z-Type Shape

The Z type configuration is generally considered the strongest and most efficient.

These shapes resemble wide-flange beams, having a web and two flanges. The interlocks are located out on the flanges at maximum distance from the neutral axis, and this provides a high section modulus for resisting bending moments.

Because of this, Z-shapes have traditionally been used for heavier construction projects. However, they are now complemented by the arch or U shapes for lighter work, and lightweight Z-shapes have been also introduced into the marketplace.

Because of their inherent strength, Z-piles can be handled and shipped with less exposure to possible damage than some other style sheets.

Z-piles are generally used in constructing straight wall structures – cofferdams, bulkheads and retaining walls.

U-Shape Piles

U-type sheet piles are not generally used in some area as they are not as efficient or economical as Z-type sheet piles. Interlocks on u-type piles are located on the neutral axis of the pile, so the sheet piles must be crimped in order to achieve their full capacity. These types of sheet piles are still available in the international market.

Flat Sheet Piles

Flat sheet piles are used for circular cell applications where the cells form a gravity structure. The sheet piles are interlocked together to form individual cells, or a series of cells, and are then filled with soil. Whereas z-type sheet piles require resistance in bending, the strength of the flat sheets come from their interlocks. Flat sheet interlocks are larger than those on z-type sheet piles and are designed to resist significant tensile forces. Flat sheet piles have limited bending capacity.

FAMOUS offer a wide range of Z piles, from EZ17s through to ZZ46-700s.
