I-Bar Grating

I-bar grating uses a bearing bar with wider flanges and a narrower web instead of a solid rectangular section. The profile places material where it contributes efficiently, making it a practical lightweight option—commonly in aluminum systems—when the selected span and load fall within its confirmed range.

  • I-shaped bearing profile with visible flange and web
  • Lower material use than a comparable solid rectangular profile
  • Common in lightweight aluminum grating systems
  • Profile series confirmed against span and load

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, follow the related product route; do not force an I-bar into the specification.

Variants

Recommended Types

Plain I-bar profile

A smooth top flange for dry or controlled areas where additional slip resistance is not specified.

Serrated I-bar profile

A profiled walking edge considered for wet or exposed access; exact surface is confirmed per project.

Fabrication & QC

Fabrication & Quality Notes

  • Profile geometry, alloy, cross-bar arrangement and panel size are confirmed per project.
  • Cut-outs and banding details follow approved panel drawings.
  • Finished panels are protected from carbon-steel contamination during handling and packing.

Packaging

Packaging & Delivery

  • Packing method is selected from strapped bundles, pallets or steel frames according to panel type, finish and site handling.
  • Panel tags and packing-list references follow the approved layout numbering when a project panel schedule is supplied.
  • Container loading is calculated per shipment from panel dimensions, bundle weight, packing method and destination limits.

FAQ

I-Bar Grating FAQs

Is I-bar grating always aluminum?
It is commonly supplied as an aluminum profile, but the actual material and series must be confirmed from the project specification and available construction.
Is an I-bar automatically equal to a rectangular bar?
No. Compare the verified profile geometry, material, span, load type and deflection criteria. Similar depth does not prove equal capacity.
What information is needed for selection?
Provide clear span, load types, support details, environment, slip requirement, panel layout and quantity. The alloy and profile series are then confirmed per project.
