- Hollow vessels may require temporary stays during the galvanizing process to prevent distortion
- Hollow vessels should have at least 1 vent hole and 1 drain hole
- Standard minimum venting and draining for an enclosed volume is a 50mm diameter hole for each 0.5m3 (see Table 4)
- Openings should finish flush inside the vessel
- Baffles inside vessels should have openings to allow free flow of liquid throughout. A minimum of 75mm snipes is required. See Figures 8 to 11 for more information on snipes
