Product description

tkL 604A Steel Sheet Pile – The Economical Solution for Deep Excavations and High Earth Pressures

The tkL 604A steel sheet pile bridges the gap between the lighter profiles of the 603 series and the heavy-duty profiles designed for extreme depths. With a flexural moment of resistance of 1,564 cm³/m at a profiled wall height of 390 mm, these Larsen-type sheet piles safely withstand massive loads without straining the budget with unnecessary additional weight. Compared to the tkL 601 through tkL 603 models, it offers a significant increase in bearing capacity and thus represents the most economical solution for demanding civil engineering projects in urban and infrastructure settings. This profile helps overcome the classic challenge of meeting high structural requirements while optimizing material usage per square meter of wall area.

Good for your site

Maximum driving stability thanks to a web thickness of 8.8 mm and a back thickness of 9.6 mm, which guarantees deformation-free driving even in dense grounds.
Optimized interlocking geometry of the Larssen interlock ensures smooth interlocking, precise guidance, and fast, secure interlocking during the driving or pressing process.
Excellent system compatibility and robustness, allowing the profiles to be driven in and pulled out multiple times without damage, even at the harshest job site conditions.

Good for your budget

Optimized steel weight of 118.3 kg/m², which, in the ratio to the high moment of resistance of 1,564 cm³/m, ensures outstanding material efficiency.
Reduced logistics costs for transport and handling, as the lower weight per meter of the individual sheet (71.0 kg) allows for more square meters of installed sheet pile wall per truckload.
High resale value and first-class investment security thanks to the durability and market presence of the proven tkL profile.

Good for your planning

Reliable and precisely calculable bearing capacity according to Eurocode 3 with a plastic moment of resistance of 1,823 cm³/m for maximum planning reliability at the stage of structural analysis.
Design flexibility thanks to the system width of 600 mm and a high moment of inertia of 30,495 cm⁴/m, which minimizes deflection at deep excavations.
Full sustainability and recyclability of the steel used, which can be 100 percent recycled or reused in a reusable system after its service life.
