The solution for this request was a custom-colored nylon netting construction that would closely blend-in with the surrounding infrastructure. All of the steel at Coors Field is painted a specific green color that is known as "Coors Green", so it was requested that the netting be fabricated to match that color pigment as to remain as camouflaged as possible when installed.
The goal over at Coors Field was to completely block-off the mezzanine stairwells to keep small birds from entering and nesting in those areas. Also, the netting would be a multi-purpose barrier to prevent various and miscellaneous objects from being able to fall or passed-through the existing rails. the best match for this type of installation, taking into account the custom coloring, was the #26 X 1" square mesh braided-knotless nylon netting. The 1" mesh size functions very well for small bird barrier (as well as general-purpose containment), and the mid-weight #26 twine thickness (2.2mm) provides for long-term durability in terms of exposure and abrasion.
Each net was constructed to particular heights and lengths to match the open areas that needed to be blocked-off, and there was a total of 231' of netting required to cover the center-field stairways. Each net was colored to the custom "Coors Green" pigment, and featured a 5/16" rope bordering sewn-in around the perimeter edges. The netting was then installed on-site by the local contractor in-charge of the project - and they clipped the netting tightly between tensioned cables.
