3.3.3 Metal pretreatment cost
Typical pretreatments for metal work pieces include phosphating and abrasive blasting.
Phosphating (i.e., iron and zinc phosphating) is a process of depositing a conversion
coating onto steel or galvanized steel to enhance the paint coating’s adhesion to the metal
surface. Abrasive blasting is a method of both cleaning corrosion and other surface
contaminants from metal work pieces and giving the substrate a textured profile. Costs
associated with these activities may be assigned to products based on the number of
products for phosphating.
