North American Aggregates

North American Aggregates mines sand from the Ambrose Federal Navigation Channel, a naturally replenishing source in the lower New York Bay. Their process begins with their trailing suction hopper dredge, Eleanor, mining and sizing virgin source aggregates. The Ambrose Channel’s clean sands have a long history of successful use in the tri-state area.

Their environmentally friendly process avoids the erosion and destruction of habitat caused by traditional sand mining, while ensuring that the Ambrose Channel remains navigable without relying on government funding for maintenance. The company is permitted by both the New Jersey Department of Environmental Protection and United Sates Army Corps of Engineers to mine two million cubic yards annually from the Ambrose Channel.

The new sand processing plant that was designed and built by Mellott Company was unveiled for the public. Mellott Company chose hot-dip galvanizing for this project since it is in some of the harshest conditions for any metal is submerged in or near water whether fresh water or sea water. Steel and zinc are no exceptions. However, hot-dip galvanized steel has been successfully used in both fresh and sea water exposure for decades on dams, docks, piers, and even the harsh conditions of water treatment facilities.

Mellott Company worked directly with the galvanizer to hot dip galvanize the structural steel for the sand mining equipment, conveyors and processing. They utilization of a the AGA Design Seminar during the design process helped to set up both the manufacturer and the galvanizer for success. The project consisted of 500-tons of galvanized steel.
