Color Coated Steel Coil
>
Manufactured to exacting surface quality and dimensional tolerance standards for the home appliance industry. Produced on precision cold rolling mills with continuous galvanizing and coil coating optimized for thin gauges from 0.12mm to 0.5mm. The coating formulation resists household chemicals, cleaning agents, food acids, and grease. Anti-fingerprint additives are incorporated, and back-side coatings are compatible with polyurethane foam insulation for refrigerator manufacturing. Color consistency is maintained within Delta E less than 0.5 across batches.
