Featured Projects

National Museum

World War II

New Orleans, LA

 

When Architect/Engineer Voorsanger Mathes LLC secured their design plans for the new WWII museum in New Orleans, they partnered with us to make their breakthrough design a reality. Our team produced a number of metal features using specific metallic silver and battleship gray colors to fit the museum’s brand and achieve the interior design. We developed custom ceiling grilles and aluminum dovetail handrail infilling to ensure the National World War II Museum did justice to our fallen soldiers.

Big River

Crossing

Memphis, TN

 

The Big River Crossing is the country's longest active bridge for rail, bicycles, and pedestrians. This mile-long engineering feat provides residents new opportunities for recreation and fitness with a stunning view. In partnership with the City of Memphis, OGI provided a combined 124,000 square feet of materials to construct the walkway deck, fence, and handrails to make this Mississippi river crossing a reality.

LeMay Wastewater

Treatment Plant

St. Louis, Missouri

 

When the Metropolitan Sewer District needed to upgrade a crucial water treatment plant in St. Louis, we provided more than 45,000 SF of aluminum swaged bar grating to enhance the safety and functionality of twelve water clarifiers. Nearly thirty years later, the materials we used are still in service today and continue to play an integral role at LeMay Wastewater Treatment Plant—the fourth largest wastewater collection system in the US.
