What We Build in Aluminum

Off-Road Components

Aluminum is ideal for weight-sensitive off-road parts. We fabricate:

  • Skid plates
  • Roof panels and doors
  • Dash panels and switch mounts
  • Battery boxes and coolant shrouds
  • Custom bodywork and armor

Structural & Industrial Parts

We also provide aluminum fabrication for:

  • Custom brackets and trays
  • HVAC and marine components
  • Machine covers and housings
  • Racking and frame supports

Each piece is laser cut, bent, and TIG welded to your spec—no warping, no shortcuts.

Why Choose Aluminum?

  • Lightweight Strength - Aluminum offers an ideal strength-to-weight ratio for off-road and racing applications, reducing overall vehicle weight without sacrificing integrity.
  • Corrosion Resistance - Aluminum’s natural resistance to rust makes it perfect for exposed parts—especially in marine or wet environments.
  • Clean TIG Welds - We specialize in TIG welding aluminum, giving each seam a clean, strong finish that stands up to vibration, heat, and fatigue.
  • Versatility - From sheet panels to formed enclosures, aluminum is one of the most versatile materials we work with—and one of our top specialties.

FAQs About Our Aluminum Services

  • What types of aluminum do you work with?

    We commonly work with 5052, 6061, and 3003 grades in sheet, tube, and plate form. Contact us for special requests.

  • Can you help design aluminum parts?

    Yes. We offer basic CAD assistance and can reverse engineer from an existing piece or sketch.

  • Do you work with thin-gauge material?

    Absolutely. We fabricate in gauges from .040” and up for panels, dashes, and shrouds.

  • Is aluminum stronger than steel?

    It depends on the application. Aluminum is lighter and rust-resistant, but steel is stronger in direct stress. We’ll help you choose the right material for your use case.
