Essential design guide for sections

ArcelorMittal Orange book allows you to rapidly flip through tables on structural 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 optimise 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.

ArcelorMittal Europe is the undisputable leader to deliver high strength steels for construction applications.

  • S355/HISTAR®355 and S460/HISTAR®460

HISTAR® steels are structural grades with a low alloy content, combining high strength, good toughness and superior weldability. HISTAR® grades are delivered in accordance with the European Technical Assessment ETA-10/0156 and are available with minimum yield strengths of 355 or 460 MPa. When compared to standard structural steels, HISTAR® grades feature improved guaranteed mechanical characteristics.
