  • ACB® and Angelina® beams

The castellated ACB® and Angelina™ beams, with their circular and sinusoidal web openings, elegantly combine function with flexibility. Alternatives to trusses and open-web joist systems, castellated beams are lightweight, long-spanning, structural elements that enable the design of vast column-free spaces. They can be used in composite or non-composite systems. 

Their web openings permit installation of mechanical, electrical and plumbing (MEP) pipes and ducts within the depth of the beam, thereby allowing for compact ceiling systems and maximized floor-to-ceiling heights. In addition, the repetition of the perforations ensures that variations, during construction or throughout the life of the structure, in the layout of the MEP system can easily be accommodated. 

Architecturally striking, castellated ACB® and Angelina™ beams are every year seeing increased use in the built environment. Today, with improvements that have been implemented in design standards, analysis tools, and manufacturing, it is easier than ever to incorporate them into a framing system. 

 

Angelina® with composite slab

 

Cofraplus® 220 combines the outstanding resistance of the patented steel profile with the performance of a ribbed reinforced concrete slab. The total load bearing capacity results as the sum of the resistance of both elements, as no composite action is taken into account.
The high values of moment of inertia and moment of span guarantee large span without propping.
Cofraplus® 220 sheets are available with thicknesses of 1, 1.13 and 1.25 mm, with a maximum length of 9 m.
