Mubea bietet Leichtbaukomponenten mit beanspruchungs- und funktionsoptimierter Blechdickenverteilung.


Tailor Rolled Products

Ever-increasing requirements with regard to crash performance, weight, emissions and cost-effectiveness call for efficient lightweight construction. Mubea offers lightweight components with load- and function-optimized sheet thickness variation to generate the corresponding benefits:


  • Reduced weight
  • Improved component performance
  • Simplified design with the potential to reduce costs

Technology pioneer with more than 20 years of experience : MANY YEARS OF EXPERIENCE WITH TAILOR ROLLED PRODUCTS

We developed flexible rolling technology in the late 1990s. With the construction of our first rolling mill in Attendorn, Germany, in 2004, technology pioneer Mubea began large series production. Having in excess of 15 years experience in the manufacture of tailor rolled products, Mubea now supplies series products to almost every international customer in highly diverse vehicle segments ranging from subcompacts to luxury sedans.

Tailor rolled components are primarily used in main crash load paths : Making light work of safety

Tailor rolled products exhibit different stresses and demands along their length. With tailor rolled technology, components can be cost-effectively and optimally adapted to local requirements.

Longitudinal and transverse structures for maximum lightweight construction potential and optimized performance : TOP APPLICATIONS IN THE CAR BODY


Examples of series applications for longitudinal structures:

  • Tunnels, rocker panels, front/rear side members, A-pillars/roof frame


Examples of series applications for transverse structures:

  • Heelboards, seat cross members, cowl cross members, front bulkhead cross members
Maximales Leichtbaupotenzial bei optimierter Performance

Ideal construction design for maximum leverage of TRB advantages:

  • Reduction in weight and cost with simultaneously increased performance
  • Linear, harmonious sheet thickness transitions to reduce stress peaks in crash-critical components
  • Lightweight construction potential greater than 20 percent per component
  • Individual material concepts for optimum lightweight applications
  • Cost optimization through the integration of components

B-pillar: ideal component design for maximum benefit to the customer : TOP APPLICATIONS IN THE CAR BODY

The B-pillar is exposed to a conflict of objectives in the vehicle: the very complex occupant protection tasks contrast with the challenging package requirements determined by the vehicle design. As a result, there are numerous different cross sections along the component that are in turn subject not only to highly diverse loads such as side impact and roof load, but also to stiffness requirements. The use of the correct wall thickness at the right point on the TRB offers substantial advantages in this respect.

Ideale Bauteilauslegung für maximalen Kundennutzen


  • Maximum weight reduction through the use of ultrahigh-tensile structural components with load-adapted wall strength characteristics
  • Possibility of introducing a soft zone for additional local ductility depending on load profile
  • Linear, harmonious sheet thickness transitions to reduce local stress peaks
  • Avoidance of stiffness deflection compared with reinforcement patches
  • Better crash performance: wall thicknesses determined by simulations to harmonize stresses in the event of a crash
  • Cost optimization through the integration of components: additional joining operations and logistics costs no longer required
  • Improved corrosion behavior compared with multipart variants/welded blanks

Crash management system: fulfils all functional requirements while minimizing weight : TOP APPLICATIONS IN THE CAR BODY

Erfüllung aller Funktionsanforderungen bei gleichzeitiger Minimierung des Gewichts.


  • Optimal, even distribution of stresses through the localized adjustment of wall thickness to improve performance and material utilization
  • Efficient design for various vehicle derivatives by adapting the wall thickness profile to different vehicle weights/local market requirements
  • Cost optimization through the integration of components: additional joining operations and logistics costs no longer required
  • Perfect design of energy absorption and collapse behavior in crash boxes by optimizing the wall thickness profile with harmonious transitions; no need to install crash initiators
  • Determination of wall thicknesses enables a constant component section with uniform performance for optimized material utilization
  • Improved corrosion behavior compared with multipart variants
  • Functional synergies of different TRB components in one modular element



In the flexible rolling procedure, the continuous control of the roll gap in the cold rolling process incorporates different wall thicknesses in the longitudinal direction with linear, harmonious transitions into the material.


The fully laser-controlled monitoring in a closed control loop makes it possible to achieve minimal wall thickness tolerances regardless of sheet thickness.
