PREON box - Hall solution


PREON® box - 
The unbeatable duo, combining MSH with unique planning software for column-free hall construction 

PREON® box drastically simplifies the construction of wide span steel structures and saves up to 30% in materials..

PREON® box: A unique software

Vallourec developed planning software that integratesMSH static values in load

assumptions for foundation and structural calculations.
  • Provides the planning data you need: for processingyour project at every phase
    - from foundation to detailedengineering
  • Easy to use:
    allows comparisons of single and multi-aisled halls to be made at the push of a button

PREON®box: The MSH hollow section

Vallourec, MSH hot-finished hollow section (acc. EN 10210) brings numerous advantages compared to open sections: 

  • Higher static values: allow weight savings up to 30%
  • Simplied operations: sharp edges, tight corners make welding easier
  • Less surface area: saving 50% in surface coating material
  • Visually impressive: closed and simple geometry creates clear lines with sharp edges

Advantages of PREON® box

  • Unique iterative planning software for faster, more secure and flexible structural design
  • Easy modification of the statics during the entire planning period
  • Attractive appearance and high load-bearing capacity thanks to steel framework elements made from hot-rolled structural hollow sections (MSH)
  • Up to 30% savings on material weight due to automated static calculations
  • Substantial time and cost savings during workshop production of the load-bearing modules as well as during transport and assembly as a result of the software-optimized structural design
  • Up to 30% shorter planning times
  • 30% to 50% less material required for corrosion protection (due to fewer surfaces compared to open sections)
  • Particularly suitable for applications with high demand on cleanliness through the use of closed sections


MSH Section Properties

  • Application-specific steel grades
  • A wide size range
  • High load-bearing capacity
  • Tight corner radii (up to 1 x T on request) for optimum joint and welding properties
  • Higher weights and higher static values than cold formed profiles due to the hot finishing process
  • Ideal corrosion- and fire protection
