Steel beam ANGELINA®

Ihollowfor flooring

Sleek, open, transparent and flexible, Angelina® beams offer a new architectural dimension within an environmentally friendly approach. With their sinusoidal web openings, they elegantly combine function with flexibility, integrating technical installations and optimising the weight/height or load/weight ratio. These lightweight, long-spanning, structural elements enable the design of vast column-free spaces and present an interesting alternative to trusses and open-web joist systems. Thanks to a reduced production time and substantial material savings, Angelina® also meets the economic requirements of your projects. Thanks to their numerous benefits, Angelina® beams are included in ArcelorMittal’s comprehensive, science-based Steligence® concept which will facilitate the next generation of high-performance buildings and construction techniques, creating a more sustainable life-cycle for buildings. Angelina® beams are fabricated based on the exclusive use of hot rolled sections. A single cut-out is made in the web by flame cutting and the two obtained T-sections are shifted and rewelded leading to an increase in height. The structural product thus obtained has an increased ratio of moment of inertia to weight. For a given section, height, length, and spacing of openings are variable resulting in extremely adjustable beam geometry and perfect suitability to project requirements.
