Product description

TKL 604 Steel Sheet Pile – The Powerhouse for Deep Excavations and Heavy Loads

When earth pressure increases and standard profiles reach their limits, the TKL 604 comes into its own. With an elastic moment of resistance of 1,618 cm³/m and an impressive wall height of 390 mm, this steel sheet pile is specifically designed for demanding civil engineering projects where lighter profiles, such as the 603 series, must be structurally adequate. Every single Larssen-type sheet pile of this quality transforms its enormous structural bearing capacity into pure economic efficiency on the site. Thanks to its perfectly balanced geometry, this Larssen profile confidently withstands extreme bending stresses in deep excavation pits and in harbour constructions.

Good for your construction site

Maximum driving stability: The robust wall height of 390 mm and a web thickness of 9.0 mm ensure that each sheet remains dimensionally stable even on hard building ground.
Precise interlocking geometry: The proven Larssen interlock ensures low-friction interlocking during driving and guarantees excellent force transmission between the sheet piles.
Outstanding system watertightness: The tight linkages reliably withstand water pressure and minimize the need for additional waterproofing measures in the excavation.

Good for your budget

Optimized material efficiency: With a dead weight of 121.8 kg/m², the profile offers an excellent ratio of static resistance to steel weight used, which significantly lowers material costs.
High reusability: Thanks to its robust back thickness of 10.0 mm, the Larssen-type 604 profile is extremely durable and can be easily pulled in multiple times and reused on subsequent construction sites.
Reduced logistics costs: The optimized construction width of 600 mm ensures rapid construction progress and also allows for the optimization of transportation costs per square meter of installed sheet piles.

Good for your planning

Legally compliant design: The structural values for the elastic (1.618 cm³/m) and plastic moments of resistance (1.885 cm³/m) allow for a seamless, uncompromising load-bearing capacity calculation in accordance with Eurocode 3.
Design flexibility: The profile can be ideally combined with lighter types (such as the tkL 603) or the even heavier profiles of the 605 and 606 series to perfectly adapt the wall to varying depths.
Sustainable Foundation: Steel is 100% recyclable, which significantly improves the environmental footprint of your entire structure right from the planning phase.
