Heavy-Duty Tubular Steel Columns for Wharf and Marine Infrastructure – EN 10219 Hollow Sections with Hot-Dip Galvanizing

Our heavy-duty tubular steel columns combine the structural efficiency of EN 10219 hollow sections with the corrosion resistance of hot-dip galvanizing — engineered to withstand saltwater exposure, wave impact and heavy dynamic loads in wharfs, ports and offshore facilities.

1. EN 10219 Hollow Sections – Structural Advantage for Marine Use

Our columns are produced from EN 10219 cold-formed welded structural hollow sections in circular (CHS), square (SHS) and rectangular (RHS) profiles. EN 10219 covers non-alloy and fine-grain structural steels with specified yield strengths, making it ideal for heavy-duty marine construction.

• • High strength-to-weight ratio – reduces foundation loads and simplifies lifting

• • Uniform geometry – allows precise connection design and predictable structural behaviour

• • Closed section – resists both bending and torsion, ideal for wave and wind loading

• • Weldability – suitable for shop and field welding under qualified procedures

2. Engineered for Wharf and Marine Infrastructure

Wharf and marine infrastructure demand columns that resist saltwater corrosion, wave impact, wind loading and heavy operational loads:

• • High Load Capacity: Suitable for crane rails, mooring points and heavy deck structures

• • Fatigue Resistance: Withstands cyclic loading from waves, vessels and cargo handling

• • Impact Toughness: EN 10219 steel grades perform reliably in low-temperature marine conditions

• • Design Flexibility: Custom section sizes and wall thicknesses matched to project loads

Whether your project involves a container terminal, bulk cargo wharf, fishing port or offshore supply base, these columns provide a robust structural solution.

3. Hot-Dip Galvanizing – Corrosion Protection for Harsh Marine Environments

Hot-dip galvanizing is the preferred corrosion protection for marine steel because it provides barrier protection and sacrificial cathodic protection. Our columns are galvanized to EN ISO 1461, with coating thickness tailored to the severity of the marine environment.

The zinc coating protects the steel even if the surface is scratched or damaged — making it ideal for marine environments where maintenance access is difficult and costly.

4. Custom Fabrication & Connection Design

Every marine project has unique structural requirements. We provide custom fabrication for tubular steel columns, including:

• • Section size and wall thickness tailored to load calculations

• • Column length customized for wharf deck height and foundation layout

• • Connection details — base plates, cap plates, gusset plates, and bolted or welded interfaces

• • Cutting, drilling and beveling to precise dimensions

• • Trial assembly to verify fit before shipment

Our engineering team provides shop drawings, 3D models and structural calculations for seamless integration with your marine structure — plus prefabrication and trial assembly to reduce on-site work and speed up installation.

5. Quality Control & Inspection

• • Material Traceability: Mill test certificates for all EN 10219 hollow sections

• • Welding Quality: Qualified welding procedures and certified welders

• • NDT Inspection: UT, MT or PT on critical joints as specified

• • Dimensional Verification: Length, straightness and hole positions checked

• • Coating Inspection: Galvanizing thickness and adhesion tested

• • Documentation: Inspection reports, test certificates and as-built records provided

6. Typical Applications

These heavy-duty tubular steel columns are widely used in:

• • Wharf and jetty structures

• • Port and marine terminals

• • Offshore platforms and coastal infrastructure

• • Crane rails and mooring systems

• • Heavy-duty industrial platforms near water

• • Bridge piers in marine environments

Their combination of high strength, corrosion resistance and design flexibility suits both new construction and upgrade projects.

7. Packaging & Support

Marine-grade export packing:

• • Columns securely strapped with steel bands and wooden dunnage between layers

• • Wrapped with moisture-resistant film or VCI paper to protect galvanized surfaces during ocean transit

• • Clearly marked with item numbers, lengths and shipping marks

• • Shipped in 20ft/40ft containers, flat racks or bulk vessels for over-length units

After-sales support:

• • Technical documents: Mill test certificates, welding records, NDT reports and dimensional records

• • Installation guidance: Remote or on-site technical supervision for marine erection and connection works

• • Spare parts: Bolts, base plates and touch-up galvanizing coatings

• • Quality assurance: Full material traceability and compliance documentation for project acceptance

• • Coastal site support: Guidance on handling, storage and installation in salt-spray environments
