​​Applying coating to miscellaneous metal coating encompasses a broad number of industries and businesses.  These type of operations include metal fabrication, sign making, and large scale manufacturing.


Coatings:  A material applied to a surface to identify, beautify, protect, convey a message, or minimize detection of such surface.

Miscellaneous metal parts and products:  Any metal part and product except for products that fall under other district coating rules (e.g. automobile coating, architectural coating) or specifically exempt operations and coatings (e.g. data storage discs, stencil coatings).
