Clean Room Color Coated Steel Sheet - Mill Direct
Clean room color coated steel sheet is the material of choice for engineers and facility managers constructing pharmaceutical labs, semiconductor fabrication plants, hospital operating theaters, and food processing facilities that demand contamination-free environments. Engineered to meet the stringent hygiene and surface-integrity requirements of ISO Class 1–8 cleanrooms, this specialty steel combines a cold-rolled or hot-dip galvanized substrate with a multi-layer coating system that resists bacterial growth, chemical exposure, and particulate accumulation. Unlike standard prepainted steel, clean room grade panels undergo additional surface planarization to achieve a Ra roughness value typically below 0.2 µm, ensuring that microbial colonies have virtually no surface texture in which to harbor. Whether you are outfitting a new GMP-compliant production line or retrofitting an existing facility, sourcing directly from the mill means you receive consistent batch quality, traceable mill test reports, and cost-effective pricing without intermediary markups. Our production capacity exceeds 50,000 metric tons per year, enabling reliable supply for large-scale construction and fit-out projects worldwide.
What is Clean Room Color Coated Steel Sheet?
Clean room color coated steel sheet is a factory-applied, organic-coated flat steel product specifically formulated for controlled-environment construction. A continuous coil-coating line applies a primer layer followed by a functional topcoat—commonly polyester, PVDF, or epoxy resin—onto a zinc or zinc-aluminum alloy substrate. The resulting panel delivers a non-porous, easy-to-sterilize surface that meets cleanroom wall, ceiling, and partition standards while maintaining structural rigidity and fire-resistance classifications such as Class A per ASTM E84.
Clean Room Color Coated Steel Sheet Manufacturing Process
Production begins with a cold-rolled steel coil (base thickness 0.4–1.2 mm) that is hot-dip galvanized to a coating mass of Z100–Z275 g/m². The coil then enters a continuous coil-coating line where it is chemically pre-treated, primer-coated at 5–8 µm dry film thickness, cured at 230 °C peak metal temperature, and finished with a functional topcoat of 15–25 µm. Inline inspection systems verify color uniformity (ΔE ≤ 1.0 per CIE Lab), adhesion (0T bend per EN 13523-7), and pencil hardness (≥ 2H), guaranteeing every coil meets clean room specifications before dispatch.
