Crossbar spacing can also be at 50mm or 100mm centres. Also available with serrated surface for slip resistance. Rectangular Bar Grating is the most widely used aluminium pressurelocked grating. The square crossbars are inserted through punched holes in the rectangular load bars, then permanently locked into place by swaging. Recessed crossbars provide clean, crisp lines, while the advanced swaging process eliminates the need for welding to form the panels, allowing for variety of spacing. Its aesthetic appeal and ability to meet tight tolerances make this grating ideal for architectural applications.
