While we believe hot dipped galvanizing is the superior process for protecting your ornamental metalwork project from rust, metalizing is another option worth considering for some exterior scenarios. Metallizing also applies a protective zinc layer like in galvanizing, but it is sprayed onto the piece instead of dipped. This allows fabricators to perform metallizing in house, as well as metallize pieces that are too large for hot dipped galvanizing. However, consider these disadvantages when evaluating metallizing as a potential option:  - Uniformity of the applied zinc layer will depend on the experience of the operator; some variation, and thus corrosion protection, are to be expected.  - Will not reach interior or difficult-to-access surfaces such as the area between a railing caprail and channel. This means that rust is guaranteed to develop in these areas and propagate outward.  - Reduced zinc layer density compared to hot dipped galvanizing.  At the end of the day, we recommend metallizing as a great option when hot dipped galvanizing isn’t a possibility. It will provide better rust protection, longevity, and lower lifetime maintenance requirements than going with only paint or powder coat finishing.
