Cellular beam



Using different construction techniques


Cutting edge design and construction

Large spans of 20, 30 or even 40 metres without columns in between are one of the trademarks of architect Mario Kleff and his Wandeegroup which he utilises not only for condominiums but also for the residences he designs for private clients.

Interesting is that these beams are not only structural components but also design elements as you can see in the middle image alongside - the cellular beam becomes part of a lifestyle experience.

But this extreme "design without compromise" needs special technology to be implemented.

The advantage of cellular beams compared to regular I-beams is significant - after laser cutting and welding these beams have twice the stability at a reduced weight.

As this technology was not readily available in Thailand in early 2000s, Mario Kleff contacted Siam Yamato Steel (SYS) and a local laser cutting company to produce these beams for his construction projects. The welding process was first provided by the Wandeegroup. Read the full article here.

The Wandeegroup introduced cellular beam technology in Thailand in 2007. For Kleff's achievements in the field of architecture and construction, Mario Kleff received a Letter of Recommendation for an honorary doctorate in architecture from Pichet Uthaiwattananonta, Head of the Construction Department of Pattaya City Hall. This is especially for Club Royal condominium, Park Royal 2 and the Wong Amat Tower. Each of the projects involved wide-span solutions, steel frame construction and post-tensioned concrete.
