Dovetail aluminum bar grating is a tightly locked and rigidly stable panel grid with clean lines. Produced by deforming pre-punched aluminum bearing bars and cross bars assembled in an egg-crate configuration under intense hydraulic pressure, this bar grating type allows for easy passage of heat, light and air.

Available in a variety of bar sizes and spacings with an aesthetically pleasing appearance, dovetail aluminum bar grating is ideal for architectural applications or areas subject to heavy pedestrian traffic. Examples include trench grating, waterfront areas, entranceways, catwalks, platforms, stage flooring, marine ramps, parking area perimeter facades and mezzanine flooring.

Indiana Gratings can custom-fabricate dovetail aluminum bar grating to meet your unique needs. Our veteran team of fabrication specialists is ready to work from your existing drawings or help take a custom design from idea to production.

Customer satisfaction is the highest priority at Indiana Gratings, a member of the National Association of Architectural Metal Manufacturers.
