Manufacturing Process
  1. Materials Preparation: Ready bearing bars and cross bars properly for Step 2.
  2. Bearing Bars Placement: Place bearing bars into a work-holding device that is suitable for holding bearing bars in place.
  3. Pressure Welding: This step involves cold pressing of cross bars into bearing bars at high pressure and resistance welding of the bar materials under great pressure at high temperature.
  4. Flush Trimming for Edges: Flush trimming is designed to remove the excessive portion of cross bars that extends beyond the edges of the grating panel.
  5. Cutting to Size and Shape: Cut to size and shape in strict accordance with the desirable dimensions and shapes provided for by the working drawings of the buyer.
  6. Banding for Open Ends: Banding is a welding process that closes open ends of bearing bars, and the line of cutouts if any, of the grating panel.
  7. Hot Dip Galvanizing: Once the banding process is complete, the grating panels should be finished by using the hot dip galvanizing process. The zinc coating thickness is usually 65 μm or above, which is enough to resist corrosion for 15-30 years in harsh conditions.
