Size and shape of the fabrication is an important consideration to make, during the design process for parts to be galvanized. Because hot-dip galvanizing is a total immersion process, the design must take into consideration the capacity of the galvanizing kettle; therefore, it is wise to verify kettle constraints with your galvanizer early in the design process. Almost any component can be galvanized by designing and fabricating in pieces suitable for available galvanizing facilities. Parts can also be progressively dipped by the galvanizer, to accomodate larger sizes and abnormal shapes. For reference, the average kettle length in North America is 40 feet (13m), and there are many kettles between 50-60 feet (15.24 m - 18.28 m).
