A castellated beam is a rolled steel beam that has an expanded section that allows a predetermined hexagonal pattern to be cut directly on the webs of the beam. The rolled section of the beam is then cut into two individual halves.

The castellated beams are used in the construction of bridges, dams, and high-rise structures.

What is Castellated Beam?

A castellated beam is a modified I beam where the steel I section is cut longitudinally into two halves in a certain zigzag cut, and the two sections are joined back after shifting to create a beam with a deeper web and increased strength.

The castellated beam is a rolled steel beam that has an expended section that allows a predetermined hexagonal pattern to be cut directly on the webs of the beams. Castellated beam geometric properties are typically thinner than a standard steel rolled beam.

WHY CASTELLATED BEAM USE

  • COST SAVINGS
  • THINNER , LIGHTER METAL BEAM
  • SUPERIOR SUPPORT WITHIN THE ROOF AT FRACTION OF THE WEIGHT OF TRADITIONAL WIDE FLANGE CONSTRUCTION
  • DURABLE AND AFFORDABLE BEAMS

The castellated beam is a modified steel beam. In which the beam is cut in the central web portion were no great force is present.

Cut near to neutral axis of the beam where we required less amount of material mass to resist various force.

What is Castellated Beam?

The opening shape may be hexagonal, rectangular, circular, etc.

Due to opening in web we get some benifit

  • Saving in material
  • Lighter weight
  • Due to increased depth allowed, we get more strengthen beam
  • Good aesthetic view
  • Esay handle with roof febrication work.
