Numerous design considerations guided roof material selection, including proximity to the airport, a coastal location, moderate pollution levels, and the need for longevity and low-maintenance. Any large roof near an airport must have a low reflectivity surface finish so that pilots are not blinded. Type 316 (S31600, EN 1.4401, SUS 316) stainless steel was selected because it provides the desired corrosion performance and durability. Long-term maintenance was minimized by avoiding the need for a protective paint coating, which would deteriorate over time due to jet fuel residue, pollution, and coastal salt exposure. InvariMatte, a proprietary, textured, non-directional, low-reflectivity, finish from Contrarian Metal Resources was selected for the project because of its performance on similar projects.
