Introduction

Offshore structures, deck equipment, and specialized marine vessels face extreme corrosive conditions. Our filler metals are specifically focused on high-magnesium content (e.g., ER5183, ER5087) to provide the highest level of resistance to saltwater and atmospheric corrosion available in aluminum consumables. Beyond corrosion, the wires deliver high-strength weldments essential for maintaining stability and load-bearing capacity in dynamic sea states, often required by leading classification societies for critical marine use.

Base Metal Compatibility5083-H116, 5456, 5086 (Marine Grade Alloys)
Magnesium ContentTightly controlled (e.g., 4.5% to 5.2% Mg)
Weld PorosityMinimal, controlled to meet NDT requirements

Applications

  • Welding aluminum components on FPSOs (Floating Production, Storage, and Offloading units).

  • Fabrication of aluminum pipework and gangways on offshore platforms.

  • Repair of high-speed ferry and catamaran hulls exposed to continuous sea spray.

  • Joining components in desalination plants and near-shore installations.

Payment and Shipping

  • Export Readiness: Expertise in handling export documentation required for marine and specialized international projects.

  • Packaging Integrity: Enhanced moisture barrier packaging is utilized to prevent any atmospheric degradation before use in humid shipyard environments.

  • Certificates: Full compliance certification issued for every marine-grade shipment.
