Ferralloy Inc. performed investment casting services for a subcontractor to the United States Department of Homeland Security. The project required placement of perimeter bollard pipes that provide security around the main terminal of the Reagan National Airport in Washington DC. One of the biggest challenges the architect had was figuring out how to ensure the performance, durability and structural integrity of the bollards, while at the same time, incorporating a design that would be aesthetically pleasing to the public. The bollards, caps and collars were constructed from machined and polished 304 stainless steel. This project was successfully completed in 2003.
