Skylink People Mover - Maintenance Access Stairs
DFW, TX United States | 2005
Denver International Airport (DIA) found out the hard way painted stairs on the parking garage only last 15 years. After learning this lesson, the stair towers were hot-dip galvanized (HDG) to provide durability, and realize sustainable, cost effectiveness on that portion of the $7.5 million renovation for worn out components.
Painted stairs in the airport environment have a proven track record of premature failure...
Safety has always been a major concern so HDG's projected 50 years or more of life lessened the concern. The HDG coating is harder than the steel itself making it perfect for the abrasive wear and tear of the 600 million passengers passing through the airport. The airport environment is very corrosive due to engine exhaust and extreme temperatures of hot and cold weather. Painted stairs in the airport environment have a proven track record of premature failure, and other forms of corrosion protection such as weathering steel would have required tremendous design modifications. Hot-dip galvanizing with it's metallurgical bond was the wise choice.
