Steel Sheet Pile Packaging & Handling/Transport Specifications
Packaging Requirements
Strapping
Steel sheet piles are bundled together, with each bundle firmly fastened using metal or plastic strapping to ensure structural integrity during handling.
End Protection
To avoid damage to bundle ends, they are either wrapped in heavy-duty plastic sheeting or capped with wooden guards—effectively shielding against impacts, scratches, or deformation.
Rust Protection
All bundles undergo anti-rust treatment: options include coating with anti-corrosive oil or full encapsulation in waterproof plastic film, which prevents oxidation and preserves material quality during storage and transit.
Handling & Transportation Protocols
Loading
Bundles are safely hoisted onto trucks or shipping containers using industrial cranes or forklifts, with strict adherence to load-bearing limits and balance guidelines to avoid tipping or damage.
Transit Stability
Bundles are stacked in a stable configuration and further secured (e.g., with additional strapping or blocking) to eliminate shifting, collision, or displacement during transportation—critical for preventing both product damage and safety hazards.
Unloading
Upon arrival at the construction site, bundles are carefully unloaded and positioned for immediate deployment, streamlining workflow and minimizing on-site handling delays.

2. What is the difference between S355 and S355GP?
S355: Typical engineering steel section. Applications of it includes beams, plates etc.
S355GP: Grade of sheet pile, with more stringent requirements on chemical composition and mechanical properties to provide best piling performance, durability and weldability.
3. What are S355 / S355GP sheet piles mainly used for?
They are implemented in medium and heavy duty applications such as the following:
Ports and harbors
Seawall / Coastal Defense
Cofferdams
Bridge foundations ,
Permanent/temporary retaining Wall,
Protection from floods, riverbank protection

Material specifications: EN 10025 (S355), EN 10248 (S355GP)
Design standards: Eurocode, AISC (converted), JIS (for Asia projects)
Certificate: CE, FPC, ISO9001, SGS (if necessary)
5. What sizes are available for S355 / S355GP sheet piles?
Typical effective widths and heights comprise of:
Widths of 400 mm, 500 mm and 600 mm
Heights 100–225 mm
Thickness range: appr ox. 9. 4–19mm
Length: 6–24 m (custom lengths available)
6. Are hot-rolled sheet piles better than cold-formed ones?
Yes for rough work:
Hot-rolled piles have stronger interlocks
Better water tightness
Stronger fatigue resistance and durability
Good for permanent works.
7. Can S355 / S355GP sheet piles be welded or cut?
Yes. They have good weldability and may be:
Cut to length
Punched (as for metal sheets)
Welded with fitting plates, corners and taping beams
Machined to order.
8. Can S355 / S355GP be used as a substitute for ASTM A588 or JIS SM490B?
Yes, for many applications S355 / S355GP is the nearest equivalent strength class to:
ASTM A572 Grade 50
ASTM A588
JIS SM490
It has to be approved by the Project Engineer and follow the projects Design Code as a final substitution.
9. Are custom profiles and lengths available?
Yes. In addition to normal PU/U profiles, customized sizes, locks and lengths can be manufactured based on the project drawing.
