Egg Crate

Ornamental grating with your choice of blade size, orientation, configuration and frame

EG series grilles are extremely versatile and add aesthetic enhancement to any building. We manufacture grilles using single-barrel or double-barrel spacing to customize your look and geometric pattern. EG series grilles range from 1” to 6” in depth with customizable bar spacing from 2” up to 12”. The pressure lock construction method provides a strong, durable connection without welding and prevents rattling in the wind. Our EGS series features one-directional bars with a 45-degree rotation for a custom look and enhanced solar screening. You can choose between a weather-resistant mill finish or PVDF or polyester powder coat finish.

Physical Science Building

Mesa Community College

Mesa, AZ


The SmithGroup architects needed sleek, reliable aluminum grating to achieve their innovative design on Mesa Community College’s campus. We partnered with the firm to supply 1,168 square feet of LEED aluminum grating for modern scrims at the planetarium, impressive staircases and a walkable observation platform. The Physical Science building is the first of its kind on campus and was the first major LEED project in the Maricopa County Community College District.

Big River


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.
