Cellular beam
Type of beam
Cellular beam is a further development of the traditional castellated beam. The advantage of the steel beam castellation process is that it increases strength without adding weight, making both versions an inexpensive solution to achieve maximum structural load capacity in building construction.
The difference between cellular beam and castellated beam is the visual characteristic. A cellular beam has round openings (circular pattern) while the castellated beam has hexagonal openings (hexagonal pattern), both of which are achieved by a cutting and welding process. Cellular beams are usually made of structural steel, but can also be made of other materials. The cellular beam is a structural element that mainly withstands structural load laterally applied to the axis of the beam, and influences the overall performance of steel framed buildings. The type of deflection is mainly done by bending.
Introduction
In 1987, Westok Structural Services Ltd of Wakefield invented and patented the structural steel cellular beam.
In 2009, the Steel Construction Institute developed software to assist engineers evaluating the dynamic behaviour of composite floors supported by cellular beams.
Since 1940, civil engineers have endeavoured to find solutions to reduce the cost and weight of steel frame construction.
Begin with the source’s own compact description: “Cellular beam” is type of beam. The dossier treats that line as a proposition to test through Cellular, beam and Type, not as a finished interpretation.
Why this record matters
The phrase “type of beam” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 24, 2026. The linked authority identifier is Q107133217. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1987, 2009 and 1940.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
