I-Bar Grating

I-bar versus rectangular bearing bars

A rectangular bearing bar keeps the same thickness through its depth. An I-bar narrows the web and retains wider flanges, reducing material while preserving useful section depth. That can lower panel weight for handling and supporting structures, but the profile cannot be substituted by appearance alone.

Compare the actual profile series, alloy, clear span, load type, deflection criterion and bearing direction. Where a rectangular bar or another construction is more suitable, use the related product route rather than forcing an I-bar into the specification.

Alloy choice for I-bar profiles

I-bar grating is commonly associated with extruded aluminum because extrusion can form the flange-and-web profile consistently. The alloy, temper, profile geometry, cross-bar arrangement and surface finish must be evaluated as one system; a profile from one series is not automatically equivalent to another.

Select the alloy and finish from the environment and fabrication route, then verify capacity from the actual profile data. Anodizing, powder coating or mill finish can be considered where applicable, with color and finish requirements confirmed against the order.

• Request the exact profile series rather than a generic I-bar description
• Confirm alloy, temper, span, load and deflection together
• Check serrated or plain surface against the slip environment
• Keep rectangular-bar and welded alternatives as separate selections
