Dome in China: VMZINC at the very top!



Dome in China: VMZINC at the very top!

Zinc is not frequently used in very tall buildings. In general, the roofs of tall buildings are topped with terraces that often house air conditioning and ventilation equipment, as well as lift motors.

Built in 1928, the Chrysler Building in New York opened the way for spectacular roofs on tall buildings, with its facetted stainless steel crown.

Striking examples of zinc in emerging markets

Today, the rapid development of the use of zinc in facade and the fact that it is now possible to integrate composite zinc panels in cladding of curtain walls (unitized systems) have given us some striking examples, especially in emerging markets.

Several recent constructions in Asia confirm this trend.
I chose one of these, which I particularly like, for this post.
It's a hotel in the city of Taichung, in Taiwan, which was built by Taipei company Chungan Welsun.

The zinc elements were installed using the standing seam technique on the dome itself, and using simple seaming on concentric panels. These are traditional techniques for which fixing was reinforced to resist the effects of significant low pressure winds that prevail at the site of the building.

Although technically this roof did not pose any real problems during design, things became a little more complicated during installation. As zinc is not very well known in China, we had to find and train local roofers, organise the site and make sure our technician was present during the main stages of installation.

My architecture teacher used to tell us that the beauty of a building was linked to the quality of its visual anchorage in the ground, but especially to the quality of its relationship with the sky!

Although this dome may appear modest seen from the ground, it elegantly crowns this building and at night gives it the appearance of a powerful urban signal.
