Dofasco TUBULAR PRODUCTS is a fully integrated steel tube fabricator specializing in high strength, low alloy steels for automotive structural components. Our tubular engineering design and production experience includes the following assemblies: axles, driveshafts / propshafts, suspension structures, engine cradles, crossmembers, side impact protection structures, instrument panels and trailer hitches. MultiWall T3 is our variable wall thickness tube technology producing benefits such as: mass savings, NVH optimization, enhanced energy management, component and weld reduction and improvements in dimensional capabilities.

Instrument Panel Assembly Case 1
The Improvement
Tubular Products worked cooperatively with customer to redesign the current hybrid (steel/magnesium) design to an all steel mainstream design.

The Benefits

  • Design resulted in a cost savings of 43%.
  • Annual Cost Savings exceeding $50 million.

    •  

    Instrument Panel Assembly Case 2
    The Improvement
    Co-located design engineering resources at customer’s facility to support the design responsibilities.

    The Benefits

  • Exceeded affordable target at launch and provided ongoing specification cost reductions.
  • Developed mass effective design.
  • Maximized the use of tubular solutions, while minimizing stamping content to provide ongoing flexibility for change with minimal investment.
  • The weld specifications for instrument panel assembly were written in the absence of weld specs from customer.
