Steel Sheet Pile
Category: Related products
Point:
Steel Sheet Pile is a special steel profile designed for creating retaining structures in soil and hydraulic engineering structures. The elements are connected to each other into a continuous wall using interlocking connections.
Production Technology
The manufacturing process includes the following stages:
1. Profile Design: Development of the optimal profile shape and interlock connection.
2. Hot Rolling: Rolling on special mills through a system of complex profile rolls.
3. Lock Forming: Creation of a precise interlock connection on the profile edges.
4. Cutting to Measured Lengths: Cutting by hot or cold method.
5. Quality Control: Checking lock geometry and mechanical properties.
6. Anti-Corrosion Treatment: Application of protective coatings if necessary.
Types of Sheet Pile Profiles
• Larssen (U-shaped): The most common type.
• Z-shaped: With increased bending rigidity.
• Flat: For special applications.
• Tubular: Combined profile.
Characteristics and Assortment
• Profile Width: 400-800 mm.
• Profile Height: 75-420 mm.
• Wall Thickness: 8-24 mm.
• Length: 6-24 meters.
• Mass per 1 m²: 70-240 kg.
• Section Modulus: 800-4200 cm³/m.
Advantages
• High Strength and load-bearing capacity.
• Tightness of profile connection.
• Possibility of Multiple Reuse.
• Fast Installation and dismantling.
• Resistance to aggressive environments.
• Durability (50+ years).
Areas of Application
• Hydraulic Engineering Construction: quays, embankments, dams.
• Civil Construction: excavation shoring.
• Transport Construction: bridges, tunnels, overpasses.
• Environmental Construction: anti-filtration curtains.
• Port Facilities: quay walls, breakwaters.
• Industrial Construction: retaining walls.
