4 Advantages of Using Castellated Beams

What are the advantages of using castellated beams?

  1. Offers durability
  2. Versatile
  3. Cost-efficient
  4. Lightweight


Major players in the construction industry have been constantly experimenting on ways to improve the stability of a particular building’s structure. Through modern innovations like stainless steel reinforcing bars, seamless pipes, or welded pipes, just to name a few, the structural integrity of a particular building is made stronger and more stable.

Another one of the more important innovations in this particular industry is the castellated beams. Many have been capitalizing on the advantages of castellated beams to provide the different parts of structures with more support, at a much lower cost. Through innovation and continued experimentation to produce the best construction materials, the castellated beam was devised, offering architectural projects with a less bulky, and more attractive appearance.

As such, if you’re a manager of a construction company, or if you simply want to understand more of the benefits of incorporating castellated beams into your construction projects, continue reading to learn more.


Offers durability

The castellated beam is not a relatively new invention. It was first utilized in the early 20th century, initially given the name of “Boyd beam”. Though modern innovations in this type of construction material have allowed the production of a variety of different patterns, it initially began with one pattern.

Simply put, the process of castellation involves making a zigzag-like incision on a rolled section of a beam. After, the other half is turned around and seamed to the other half. With the joining of the two patterns, the height and depth of the resulting beam are increased, ready to be utilized for a variety of constructional purposes.

Through the physical alteration of the material – and in this case, steel is particularly used – the stiffness of the beam is increased, without having to make any changes to the material’s weight. The increase in depth also results in an increase in the level of vibration resistance that the newly-cut castellated beam can withstand, compared to the original, and un-manipulated beam.

As mentioned before, castellated beams have now been manufactured in a variety of different shapes and patterns. Though it initially was produced by particularly cutting up a zigzag, or hexagonal pattern on the beam’s rolled section, modern architectural innovations have allowed the production of castellated beams coming in different shapes. There now exists castellated beams with circular, rectangular, or even sinusoidal openings. While these different varieties exist, the other half of the rolled section is still attached in the same way, through welding.

With the endless possibilities that construction companies are faced, once they’re presented with a material such as the castellated beam, they are able to manufacture the material in different designs, as they wish. This is why one of the advantages of the castellated beam over its non-castellated counterpart, is that it offers a higher level of versatility.

For this particular reason, the material has been used in many different constructional projects, like barebones stainless steel parking, rafters, or even pipe bridges. Construction companies have also learned to take advantage of the resulting holes of the material, by using them as passages for different wiring components for utilities, just to name an example.



Another benefit of using castellated beams is that they are more efficient. It wouldn’t be farfetched to imagine that aside from completing a stable structure, one of the goals of construction companies is to avoid a blowout in their budgeting. Typical reasons for why such an undesirable outcome might transpire, include, using expensive materials, or using materials which are too shoddy, yet will result in instability in the structure.

These types of situations would be avoided if durable, yet cost-efficient materials, such as the castellated beam is used. This does not mean that the construction company is cutting corners in terms of their architectural materials, but rather, this means they’re being prudent about the financial aspects.

Because a castellated beam is simply formed by combining the other half of a steel section to itself, no other complex chemical engineering is required. There is no need to chemically alter the internal structuring of the stainless steel material, in order to increase the strength. No other complicated and potentially expensive and time-consuming heat treatment procedures are required to change the grain properties of the beam.

Finally, the castellated beam’s lightweight property is another one of the reasons why construction companies find the material highly-desirable. There would be no requirement of applying a complicated chemical manipulation of the material, as it is simply derived from components inherent within itself.

Despite it being lightweight, this does not take away anything from the material’s strength properties. Nothing from the original beam is wasted in the process, if the material is cut evenly, all throughout.

The lightweight material compounded with the increased level of stability it can potentially provide a structure is what makes it the more sought-after beam component in many construction undertakings.


Key Takeaway

The simple guide above has listed just some of the many advantages of castellated beams in construction projects. Its cost-efficiency, durability, and versatility are just some of the reasons why it has been widely utilized in construction projects. Hopefully, the guide above has made you consider incorporating more of the castellated beam in future architectural endeavors.
