- Bearing Bars Placement: Place bearing bars into a work-holding device that is suitable for holding bearing bars in place.
- Pressure Welding: Cold pressing of cross bars into bearing bars at high pressure and resistance welding of the bar materials under great pressure at high temperature.
- Flush Trimming for Edges: Remove the excessive portion of cross bars that extends beyond the edges of the grating panel.
- Cutting to Size and Shape: Cut in strict accordance with the desirable dimensions and shapes provided by the buyer's working drawings.
- Banding for Open Ends: Welding process that closes open ends of bearing bars, and the line of cutouts if any, of the grating panel.
