The hot dip galvanized grating is fabricated from steel bars before the completed grid receives its zinc coating. Cutting, joining and edge preparation take place ahead of the immersion stage. This sequence treats the assembled intersections as part of the finished panel. The open construction allows rain and cleaning water to drain away, while the bearing bars carry loads between supports. Walking surfaces can use plain or serrated tops, with other bar forms available in the range. It serves exposed access areas where the steel structure and its coating must suit the location and the planned maintenance conditions.

Main Applications
The hot dip galvanized grating floors outdoor plant platforms with drainage beneath the panel.
Maintenance routes around tanks and service lines retain an open surface.
Project-shaped covers can include openings and edge bands before zinc treatment.
Completing the panel outline before finishing allows the main grid and fabricated edges to enter the same protective-coating operation.
Fabricated stair landings and walkway sections can share a finishing route while retaining different dimensions. Their panel marks keep those parts associated with the correct installation positions.
Why choose us
Our hot dip galvanized grating workshop combines automatic pressure welding, punching and general fabrication equipment. Technical staff review non-standard panel drawings and coordinate the required finishing sequence. Repeated pieces can be organized in batches for project delivery. Buyers have one production route from the agreed grid layout through assembly and surface treatment, with packing arranged around the resulting panel schedule and installation areas.
Any site cutting should be identified during order review so the finish specification also addresses the newly exposed steel at the altered edge.
FAQ
Q: Is hot dipping the same process as electro-galvanizing?
A: No. Molten-zinc immersion and electro-deposition use different coating processes.
Q: Can the walking surface be serrated?
A: Yes. Serrated bearing bars are an available option.
Q: Can openings be made before coating?
A: Yes. Their positions can be included in the fabrication drawing.
