Philadelphia Airport Parking

Situated across two major hotels, Philadelphia Airport's new parking entrance is both eye-catching as well as durable. Hot-dip galvanizing (HDG) was always included in the plan in order to ensure corrosion protection; however, the HDG finish alone was considered too industrial.

In order to cover the structure with powder coating, a smooth HDG finish was required. The airport parking was an accelerated project with a minimal time frame, which necessitated the fabricator, architect, galvanizers and painter to work together efficiently. Together they achieved a beautiful and corrosion resistant duplex system. This system, and all HDG coating provides both cathodic and barrier protection. The barrier protection simply isolates the steel from the potentially corrosive environment of Philadelphia. The cathodic protection, also known as sacrificial protection, comes from zincs ability to sacrifice itself so small areas of exposed steel are guarded. The powder coating of the duplex system provides an extra layer of barrier protection. Ultimately, Philadelphias goal to boast an unforgettable and durable airport entrance was fulfilled.
