Airports are unique public spaces—with people in constant movement through shops and concourses amid concrete and steel. Architects creating or redesigning airports today are incorporating stainless steel into both the interiors and the exteriors of their projects.
In addition to its pleasing aesthetic (alongside concrete and steel), Outokumpu stainless steel is also being specified for its structural strength, cleanability (i.e. bacteria, dirt, and stain removal), corrosion resistance, and—in the case of patterned finishes—scratch and impact resistance.
Sticking with the pattern in Miami
For the Miami International Airport reconstruction (which was completed in several phases over many years), Outokumpu’s Nyby, Sweden mill created PR17, a special linen pattern of Deco stainless sheet manufactured to meet a specific design for both interior and exterior applications.
To complement PR17 (used in an early phase), the airport’s architects selected Type 316 stainless from Outokumpu for a more recent phase of the project. Type 316 was specified for the airport’s interior column covers and for the cladding of elevator interiors and exteriors in the outdoor parking structure that connects to the airport.
The airport’s proximity to the Atlantic Ocean (an area with seawater and high humidity) required a material with exceptional corrosion resistance performance. While increasing corrosion resistance, the Outokumpu stainless selected also required less maintenance (because the linen pattern is designed to hide scratches and dirt).
Deco selected for Toronto Airport
As part of a $4.4 billion makeover at Toronto Canada’s Pearson International Airport, a linen pattern of 304 Deco stainless (provided by Outokumpu) was specified for the interior elevators. For the airport’s exterior, additional stainless steel from Outokumpu was used to form 43 roof girders in the passenger terminal. Curbside, 172 stainless steel plates were fastened with flathead socket bolts to vertical diagonal braces on the building’s roof.
With it’s exposure to road and aircraft de-icing products during the winter months, these Outokumpu products were selected for their corrosion resistance, structural strength, and aesthetic appeal.
The Miami and Toronto airport projects each used more than 100,000 lbs. of Outokumpu stainless steel.
