What is Painted Steel?

Painted steel (Baked Enamel or Powder Coated Steel) refers to a surface treatment process where the air outlet box is made from high-quality cold-rolled steel plate. After undergoing rigorous pretreatment steps including degreasing, acid washing, and phosphating, it is coated with high-performance epoxy powder coating. Finally, the coating is cured through high-temperature baking.

Steel plate baked enamel high-efficiency air diffusers can be configured with different grades of filters according to customer requirements:

Filter Grade	Efficiency (MPPS)	Application Scenarios
H13	≥ 99.95%	ISO Class 7/8 Cleanroom (Class 10,000 / 100,000)
H14	≥ 99.995%	ISO Class 5/6 Cleanroom (Class 100 / 1,000)

Advantages:

Cost-Effectiveness: Lower cost than stainless steel, making it a budget-friendly option.
Wear Resistance & Aesthetics: Features an even paint finish with strong adhesion, offering excellent wear resistance and visual appeal, with color options available.
Corrosion Protection: A high-quality baked paint coating effectively isolates air and moisture, delivering reliable rust prevention.
