Cellular beam



Mario Kleff Introduced The Cellular Beam In Park Royal 2


Cutting edge design and construction

Large spans of 20, 30 and even 40 meter without columns in between, is a design trademark of the architectural brand Mario Kleff ™. The Pattaya-based architect use the cellular beam not only in premium condominium construction, but also in luxury villas he designs for customers in Thailand.

At Majestic Residence on Phra Tamnak Hill, Mario Kleff set a new record with a cellular beam length of 48 meter.

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.

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, and later by B.S.Y. Plc. Read the full article.

Mario Kleff designs post-tensioned concrete and is the engineer on all Wandeegroup construction sites. When it comes to technical approval, Dr Songkiat Matupayont is a professional engineer and supporting partner.

For his 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.
