Notes:

• This design requires vent holes to be placed as close as possible to the flattened area.
• More than one hole may be required for larger cross section areas.
• The total area of the vent holes must equal to the area of a hole with a diameter of at least 25% of the diagonal cross-section of that joint.
• It is important to include the opposing vent holes on the other end and opposite face in a manner such that zinc will not flow out and solidify onto the steel fabrication.
• In all cases, the location of the vent holes must conform to the requirements of AS/NZS 5131 and AS 4100.
