When machinery fails, it’s rarely due to design alone, it’s often down to how the equipment was fabricated. In sectors like automation, defence, and specialist packaging, components are expected to withstand years of constant use, extreme environments, and significant stress. That’s where heavy-duty fabrication becomes essential.

Heavy-duty fabrication is essential to the integrity, durability, and functionality of modern industrial machinery. As industries evolve, especially those operating in high-load or hazardous environments like aerospace, automation, and the glass sector, components must withstand extreme stress, vibration, and wear over extended service lives. Precision-engineered fabrications up to 13 metres in length and 7.5 tonnes in weight, like those produced at GWH offer the structural robustness that modern machinery demands.

This type of engineering supports the reliability of equipment under operational duress, particularly where tight tolerances and load-bearing performance are non-negotiable. In short, heavy-duty fabrication is not just about size or weight, it’s about precision, material integrity, and functional resilience.

What Is Heavy-Duty Fabrication?

Heavy-duty fabrication refers to the engineering and manufacturing of large, high-strength components capable of withstanding intense use and pressure. It goes far beyond simple welding or sheet metal work. At GWH, we produce structures up to 13 metres long and 7.5 tonnes in weight, using processes like MIG, TIG, and ARC welding across materials such as mild steel, stainless steel, and exotic alloys.

Why It Matters: Common Industry Challenges

  • Fatigue failure from repetitive stress cycles
  • Thermal expansion in high-temperature environments
  • Misalignment and vibration affecting performance and safety

In these cases, standard fabrication won’t do. Components must be robust, precisely aligned, and engineered with materials suited to the application.

Industries That Depend on It

Robotics & Automation

In robotic production cells, even tiny vibrations or warping in support structures can throw off calibration. We fabricate ultra-rigid bases and pillars that maintain alignment under dynamic loads.

Defence Applications

We support naval and land-based platforms with fabricated assemblies designed for impact resistance and longevity in harsh conditions.

GWH’s Capabilities

We’re not a sheet metal shop. We specialise in:

  • Fabrication of large-scale structures with structural tolerances
  • High-integrity welds using coded processes
  • NDT testing (dye penetrant and others) to validate weld quality
  • Collaboration with in-house machining for hybrid fabricated-machined parts

Case Study: Defence Supplier Rebuild

A UK-based defence contractor required a structural frame for a mobile radar unit. Their previous supplier struggled with weld distortion and missed tolerances. Our team redesigned the frame using reinforced gussets and controlled weld sequences, delivering on time and within spec.

Partnering for Long-Term Performance

Choosing the right fabrication partner means ensuring your equipment lasts longer and performs better. We don’t chase short-term wins, we build long-term, heavy-duty solutions that withstand years of use.
