The first project we consulted on was for the United States Army Corps of Engineers. We put a specification for submittal which was subsequently approved. “The Corps” opted to approve a 12” wide cast iron grate in a 1.5” thickness. They chose to use an ADA style grate with a bolted assembly option. Each section had 4 stainless steel bolts for an extra layer of security. This is our first and most proud project. The United States Army Corps of Engineers demands the highest quality and technically sound product and we were approved.
