Steel Bar Grating Galvanized- 3/16″ x 1″ (24″ x 48″)

This galvanized steel bar grating panel is built from 3/16 in (4.8 mm) thick by 1 in (25.4 mm) deep bearing bars with cross bars, and is supplied as a 24 in x 48 in (610 mm x 1219 mm) panel. The grid is protected by a zinc coating and offers a plain flat top surface with an open grid pattern. Its open design provides high strength-to-weight performance while letting water, light, air, dirt and debris pass through, which keeps walking surfaces drier and cleaner.

Bar grating is one of the most widely used flooring and cover materials in industrial, commercial and infrastructure projects. The 1 in bearing-bar depth gives a good balance between load capacity and span, making this panel a practical option for platforms, mezzanines, catwalks, trench and drain covers, equipment access areas, machine guards and ventilation panels.

Why Choose Galvanized Bar Grating

Galvanized steel is carbon steel protected by a zinc coating. The zinc acts as a barrier against moisture and oxygen and also protects the steel sacrificially at small scratches and cut edges, which is why galvanized material is a long-lasting choice for outdoor, damp and industrial settings. Compared with solid plate, bar grating reduces weight, avoids water ponding and allows inspection and maintenance of equipment beneath it.

Fabrication and Installation

Panels can be field-cut with an angle grinder, abrasive saw or plasma cutter. Cut ends should be finished with edge banding where required for appearance and strength. Fix panels to supports with saddle clips, bolts or welded fixings according to your design. Galvanized steel can be cut, drilled, welded and fastened with standard metalworking tools. Zinc fumes are released when galvanized steel is welded, so work in a well-ventilated area, use appropriate respiratory protection and grind away the coating near the weld zone where possible. After cutting, welding or drilling, touch up exposed steel with a zinc-rich cold galvanizing compound to restore corrosion protection.

Storage and Handling

Handle and store the material off the ground, on dunnage, in a dry and ventilated area. Avoid stacking wet material tightly, as trapped moisture can cause white storage stain (harmless zinc oxide). Dimensions, weights and finish appearance (spangle) may vary slightly between production lots. Please verify critical dimensions and load requirements with your engineer before purchase; this product description is for general guidance and is not a substitute for engineering design.

Frequently Asked Questions

Is this grating suitable for outdoor use?
Yes. The zinc coating provides corrosion resistance suitable for outdoor and damp environments.

How is the grating sized?
This listing is a 24 in x 48 in panel with 3/16 in x 1 in bearing bars. The 1 in value is the bearing-bar depth, which drives load capacity and allowable span.

Can I cut it to a custom size?
Yes, panels can be cut on site with standard metal-cutting tools. Finish cut edges and touch up with cold galvanizing compound.
