Introduction

Manufacturing transport equipment, particularly large shipping containers (like those used by Maersk) and road trailers, requires welding materials that balance high deposition rates with long-term structural integrity. Our filler wires, mainly high-Magnesium alloys, deliver the necessary strength and resistance to fatigue and corrosion that these constantly stressed structures demand. The consistent quality supports continuous, high-speed welding processes, maximizing production efficiency while ensuring compliance with stringent freight classification requirements.

Applications

  • Welding of aluminum dry freight and refrigerated shipping containers (e.g., Maersk containers).

  • Fabrication of heavy-duty aluminum dump truck bodies and flatbed trailers.

  • Construction of specialized transportation tankers and silos.

  • Repair and modification of existing container fleets.

FAQ

  • Q: What is the main benefit of using ER5556 over ER5356 for heavy-duty trailers?
  • A: ER5556 has a slightly higher Magnesium content, which provides an incremental increase in tensile strength and typically better performance in elevated temperature applications compared to ER5356.
  • Q: How do you ensure the wires feed consistently on container fabrication lines?
  • A: We use precision layer-winding on our spools and drums combined with proprietary cleaning techniques to minimize wire friction and eliminate helix/cast issues that cause feed interruptions.

Advantages

  • High Deposition Rate: Wires are optimized for stable performance at high current settings, allowing for maximum weld metal throughput on thick plates.

  • Excellent Fatigue Strength: The weld joints maintain structural integrity under constant loading/unloading and road vibration cycles, extending equipment life.

  • Minimizes Spatter: Exceptional surface cleanliness and consistent wire geometry lead to stable arc transfer, minimizing cleanup time in high-volume production.

  • Approved by Industry Leaders: Successfully supplies representative global companies like Maersk, demonstrating proven product quality in critical logistics applications.

Payment and Shipping

  • Supplier Reliability: Capacity to meet high-volume demands with a monthly production capability exceeding 200MT.

  • Flexible Terms: Open to establishing long-term, competitive pricing models for consistent bulk purchasers.

  • Global Reach: Expertise in exporting to over 30 countries, ensuring smooth customs and delivery processes globally.
