Corrosion resistance is one of the most critical factors for marine and coastal projects.
Royal Steel Group offers multiple anti-corrosion solutions:
Black Steel Surface
Suitable for inland construction and secondary processing.
Fusion Bonded Epoxy (FBE) Coating
Offers excellent chemical resistance and long-term protection.
3PE Coating System
Consists of:
Epoxy primer
Adhesive layer
Polyethylene outer layer
This system is widely used in marine projects, offshore structures, and pipeline foundations.
1. Basement Wall Foundations: Pile foundations for the substructure of multi-story buildings, factories, warehouses, commercial and residential buildings (suitable for any building type).
2. Bridge Pile Foundations: Robust foundations for highway bridges, railway bridges and urban viaducts; suitable for simple, lightweight, fixed or floating bridges spanning rivers, lakes and oceans.
3. Port Construction: Reliable foundations for port wharves, shipyards and dock platforms, as well as port heavy equipment and cargo handling facilities.
4. Marine and Offshore Wind Power and Engineering Projects: Structural products for marine industry and offshore wind turbines, with resistance to tides, waves and marine corrosion.
5. All Large-Scale Civil Engineering: High-load-bearing piles for large-scale civil engineering projects such as dams, underground stations, tunnels, as well as industrial machinery and structural loads.

3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging
1. Packaging:
Wooden blocks or dunnage are used between layers of packaging bags or containers to prevent damage during transportation.
Surface treatment (optional): Black paint, rust-preventive oil, or plastic film rolls.
Hot-dip galvanized piles can be covered with a temporary protective film to prevent surface scratches.
Custom packaging is available.
2. Transportation:
Stock bending lengths: 6 meters, 12 meters. Non-standard lengths are also available upon project request.
Suitable for sea, rail, or road transport.
Delivery time is typically 15-30 days after receipt of payment, depending on product type and specifications.
Suitable for worldwide export, with a full set of documents (certificate of conformity, packing list, bill of lading).
3. Handling Precautions:
Securely fasten the pipes using a crane or forklift equipped with slings or slings to prevent deformation.
Store the pipes in a dry, ventilated, and cool place before installation to prevent rust.
Oversized/overweight shipments must comply with local transportation regulations.
1. Why is ASTM A500 suitable for deep foundation pipe piles?
ASTM A500 is a cold-formed structural steel pipe with tight dimensional tolerances, a high strength-to-weight ratio, and stable structural performance, ensuring precise installation of deep foundation piles for heavy infrastructure.
2. What is the difference between ASTM A500 Grade B and Grade C?
Grade B: Minimum yield strength 42,000 psi (290 MPa), suitable for piles under conventional loads.
Grade C: Higher minimum yield strength, up to 46,000 psi (317 MPa), lower maximum carbon content, suitable for high-load projects, and has good weldability.
3. What are the differences between ASTM A500 and ASTM A252 for foundation piles?
A252 is the standard pipe pile specification; A500 has tighter dimensional tolerances and a smoother surface, making it ideal for open-pit, marine, and precision foundations.
4. Can A500 steel piles be welded in the field?
Yes. Controlling carbon and manganese content reduces carbon equivalent, prevents cold cracking, and facilitates on-site splicing.
5. What types of anti-corrosion coatings are suitable for marine/exposed environments?
Three main options: Balck oil, 3PE coating, and FBE coating, suitable for corrosive coastal/marine environments.
6. Can you customize processing according to project drawings?
Yes, we can provide: customized outer diameter/wall thickness, fixed cutting length, bevels, end plates, drive bases, and lifting lugs.
7. What quality certificates are provided upon shipment?
We provide an EN10204 3.1 material testing certificate (MTC); we accept pre-shipment inspections from third-party organizations such as SGS/BV/TUV/DNV.
