Characteristics of Architectural Aluminum and Steel Coating Processes

Architectural aluminum and steel coatings involve applying protective layers to metals used in facades, windows, and structural elements. In the Netherlands, where cycling paths and windmills blend with modern skyscrapers, these processes must withstand salty coastal air and frequent rain. The exhaust from spray booths and curing ovens contains solvents like xylene and ethyl acetate, along with fine metal particles from pretreatment.

High humidity in Dutch winters can condense in exhaust streams, leading to corrosion if not managed. Our RTOs incorporate dehumidification stages to prevent this, ensuring longevity in regions like Zeeland with its maritime climate. Variability in production—such as seasonal demands for building renovations—requires systems that adjust to fluctuating exhaust volumes without losing efficiency.
