Bearing bars and cross rods are electroforged into one through use of hydraulic pressure and heat fusion. Most popular and economical choice. |
Bearing bars and cross rods are electroforged into one through use of hydraulic pressure and heat fusion. Additionally, filler bars are welded between bearing bars for added support.
|
Bearing bars and cross rods are hydraulically pressed together by cross rod deformation without welds or rivets to form a permanent bond. The permanent bond is achieved by slotting the bearing bars with a wider 'dovetail' shape at the bottom of the slot, thus locking in the cross rod when hydraulically pressed together. |
Square cross rods are swaged through punched diamond shaped holes in rectangular bearing bars. Provides lower cost alternative to press-locked grating with the same strength. Swage-locking does not provide a cross rod flush with the walking surface. |
A type of press-locked grating in which cross rods are flush with the walking surface. Provides a lower cost alternative to the traditional press-locked product. |
Bearing bars are thicker at top and bottom to provide similar strength to rectangular bar but with lighter weight. Cross rods are swage-locked. The striated top and bottom flanges provide a "built-in" skid resistance without serration. This product is the lightest weight aluminum grating alternative. |
