Swage-locked aluminum I-bar grating is assembled by permanently securing hollow tube cross bars inserted into I-shaped bearing bars with pre-punched holes using a swaging reshaping process. The I-bars bring a more economical and stronger design than the standard rectangular swaged bar grating. When the cross bars are recessed below the top surface of bearing bars, this grating type has crisp, clean lines and a striking appearance.

Available a variety of bar sizes, versatile swage-locked aluminum grating offers corrosion resistance and high strength properties in a lightweight package. The open grid construction allows for easy passage of light, air and moisture with little to zero required maintenance.

Capable of being manufactured at tighter tolerances than other grating types, swage-locked aluminum I-bar grating is ideal for a variety of applications. Those include entranceways, security screens, outdoor ventilation accents, ornamental grills, sunshades, fencing, infill panels, trench grating and bridge pedestrian walkways.

When you need aluminum grating custom fabricated to best suit your application, Indiana Gratings can take your unique design from print to production. Operating in accordance with National Association of Architectural Metal Manufacturers standards, our team combines premium materials with veteran craftsmanship and a quality-first mindset.

At Indiana Gratings, our goal is providing clients with quality products on time and at an affordable price. We value our customers, and strive to maintain relationships with loyalty, honesty and authenticity.
