Pretreatment and adhesion
Ask what pretreatment the coater uses and how it is monitored. Blasting, washing and phosphate systems each suit different substrates and service environments. For outdoor or corrosive service, pretreatment is the single biggest driver of coating life.
Capacity and logistics
Oven size and line capacity determine maximum part dimensions. For large weldments, confirm both the oven envelope and the hanging method before shipping parts across the state.
