Galvanized Steel Grating
Bar grating provides a lightweight and strong open grid steel panel that permits the passage of light, heat, and liquid, making it ideal for industrial applications, where drainage, visibility, and ventilation are critical.

BAR GRATING – CARBON, STAINLESS AND ALUMINUM: Untreated carbon steel grating, also known as bar grating, is a highly popular choice for areas where corrosion resistance is not a critical factor. We also stock painted black grating. Available in a variety of spacings, bar grating offers lightweight strength and versatility. Stainless steel and aluminum are also offered to meet your needs in a corrosive environment, or where weight is a factor.
GALVANIZED STEEL GRATING: Galvanized steel grating or painted grating is recommended in high traffic areas or locations susceptible to excessive wear, rust and other types of environmental corrosion. Galvanization is a process where bar grating stock is dipped in molten zinc, providing a tough and corrosion resistant finish. Wear-resistant painted finishes are also available in a wide array of colors.
SERRATED CARBON STEEL BAR GRATING: Serrated carbon steel bar grating is designed for anti-slip protection. Processed with a serrated top edge, serrated carbon steel bar grating is a very popular option for areas where slip protection is critical. Available in galvanized, painted, unpainted or stainless steel. Serrated grating products are used for flooring, catwalks, mezzanines, decking, stair treads, fencing, ramps, docks, trench covers, drainage pit covers, maintenance platforms, wash racks, ventilation screens, storage racks, window and machinery safeguards, factories, workshops, motor rooms, trolley channels, heavy loading areas, boiler equipment and in heavy equipment areas.
ALUMINUM GRATING: Aluminum grating products are highly prized for their strength, lightweight performance, and corrosion resistance. GNEE Steel can source a wide selection of aluminum grating sizes and spacings available for your ongoing projects.
