Steel Awards 2017 Winner of the Global Roofing Solutions Metal Cladding Category.
The new terminal building of Kasane airport caters for the airport’s growth plan and increases its capacity for international flights. The meandering floor plan called for a roofing profile that could be tapered from ridge to eaves, thereby eliminating the need for unsightly kite flashings which are notoriously difficult to waterproof on flat roofs. Zip-Tek 420 profile solved the problem.
The roof design was especially difficult as every roof sheet used on the curved sections had to be calculated and measured individually as to the required width of the sheet and also to ensure a correct radius for the curved section. The complex geometry of this project is what makes it stand out from other entries in the category.
Judges comment: Dennis White
“With cladding being continuously rolled, the profile is parallel. This building, because of its serpentine shape requires the profile to be fanned. The profile used for this project is a single pan that can be shaped to meet the requirement of curves”
