ArcelorMittal launches the extended version of its Orange book

ArcelorMittal is launching the extended version of its Orange book, an essential aid for engineers in the design of steel buildings and structures.

Already including data of ArcelorMittal Europe – Long Products’ structural sections, the ArcelorMittal Orange book is now completed with information about ArcelorMittal Europe – Flat Products for cold formed and welded sections.

What is the Orange book?

The Orange book is an online database for engineers and steel structure designers. It allows them to select the best profile shape and steel grade according to the construction specific architecture and requirements. Thanks to the Orange book and its multiple load tables, it is possible to optimize structural calculations for all type of buildings (tertiary, commercial, industrial, residential…) as well as for bridges in order to:

  • Increase spans
  • Make lighter structures thanks to higher resistance steels
  • Maximise load bearing capacities

The Orange book is part of ArcelorMittal’s digitalisation strategy which involves the creation of specific internet tools for customers, engineers, fabricators and contractors.
