Specifications for Steel Sheet Pile Packaging and Handling /Transportation
Packaging instruction
Steel sheet piles are packaged in bundles, each tightly platestack bundled with metal or plastic strapping to maintain the stack during transport.
End Protection
To protect the ends of the bundles from being bent or dented, they are wrapped with a thick plastic sheet or the ends are protected with wooden blocks - they are well protected from impact, penetration, or damage.
Rust Prevention
All the stacks are treated with rust prevention : by applying anti-rust oil or by wrapping it with waterproof plastic film, which keep the materials away from getting rusted and maintain the quality during the transportation and storage.
Handling & Transportation Protocols
Loading
Bundles are safely hoisted onto trucks or the shipping containers relying on overhead cranes or forklifts, with due attention given to load-bearing limits, weight distribution, and the avoidance of tipping or damage.
Transit Stability
Stacked bundles are arranged such that stability is achieved, and tied down (e.g., through additional strapping, blocking, etc.) to also prevent shifting, bumping, or rattling during transit – which is essential to maintain product integrity and alert-free transportation.
Unloading
On the construction site, the packs are unloaded cautiously and placed for promptly use, which makes the procedure much easier and saves extra labors.
Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling. This guarantees the H-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!

ISO9001, ISO14001, ISO45001
CE,BRC and FPC (Factory Production Control)
Inspection by SGS can be arranged on request.
Q5: What kinds of interlocks are offered?
A:Larsen interlock ans.
Hot-rolled interlock
These were used to connect reliably and to provide a continuous sheet pile wall for a retaining wall, cofferdam or seawall.
Q6: What are its typical uses?
A:Ports, harbours and seawalls
Riverbank and seashore protection
A: Cofferdams and foundation pits
A:Retaining walls within cities and irrigation canals.
Projects of land reclamation in Southeast Asia.
Q7: What kinds of processing services are there?
A: You are able to perform cutting, punching, welding and machining.
Q8: Comparison of the mechanical properties of SY295 / SY390 and S355 / S355GP?
A: SY295 / SY390 is the JIS standard equivalentS to European S355 / S355GP. They have comparable structural properties, but the JIS version is based on Japanese standards for design codes, material tolerances and certificates issued.
Q9: Is it possible to buy custom sizes?
A: It's true that there are custom widths, heights, thicknesses and lengths available for engineering projects.
