Antique bronze-gold stainless steel sheet with ice-crack pattern

Substrate Pre-treatment: The raw stainless steel sheet undergoes wax, oil, rust, and dust removal to ensure a clean surface, establishing a solid foundation for subsequent plating and coating adhesion. Antique Gold Base Coloring: PVD vacuum ion plating is the mainstream method, offering a stable coating with salt spray resistance exceeding 10 years; alternatively, a lower-cost water plating process can be used, involving copper deposition, blackening, and polishing to achieve an antique gold finish. Ice-Crackle Texture Formation: A specialized primer is applied followed by "ice-flower" paint; uniform, web-like cracks are generated via either UV curing or low-temperature freezing, with the density of the texture adjustable to requirements. Post-treatment and Protection: A transparent, dust- and stain-resistant protective lacquer is applied along with an anti-fingerprint finish; final inspection and protective film application yield the finished product, combining the three-dimensional ice-crackle texture with the sheet's wear and stain resistance.
