Marco’s Aluminum Bar Grating Options

You can choose from various types of aluminum bar grating including:

Aluminum-Bar-Grating-I-BarSwaged-Locked I-Bar Grating

Aluminum I-bar grating is extremely popular due to its superior strength, lighter weight, and low cost. It has essentially the same load-carrying capacity as rectangular bar products of equal depth. I-bar utilizes a time-test swaging process that locks the I-bars to the cross rods that are positioned at 2” to 4” intervals.

Aluminum-Bar-Grating-SwagedSwaged-Locked Rectangular Bar Grating

Aluminum rectangular bar profile is available with plain or serrated surface with the cross bar below the walking surface and fully secured within the bearing bar. This swage-locked bar grating technique closely resembles the I-bar process but the rectangular-shaped bars are used instead of I-bars.

Press-LockedPress-Locked-Aluminum-Bar-Grating Rectangular Bar Grating

Press-Locked aluminum bar grating, also called flush top grating, makes use of intense hydraulic pressure to fuse together two close-tolerance slotted bars. The pressure forces the deep cross bar into the bearing bar to achieve a permanent lock. Both the cross bars and the bearing bars provide a more comfortable walking surface with the flush top design.

Rectangular-shaped aluminum bar grating, whether swaged or press-locked, offers the most effective long-term solution when maximum lateral stiffness is essential. You can also choose a rectangular grating with a serrated surface to improve traction and prevent slipping on walkways.

Aluminum bar grating is an excellent choice for use as walkways, platforms and wherever else nonslip, corrosion-resistant surfaces are needed in high-moisture environments such as:

  • Wastewater and sewage treatment plants
  • Petroleum refineries
  • Pumping and compressor plants
  • Chemical processing plants
  • Breweries/bottling facilities
  • Food preparation/processing plants
  • Storage facilities

Our aluminum bar grating does not produce sparks, which means it can also be safely used in munitions plants and other potentially volatile manufacturing operations where fire and explosion pose a constant threat.
