• Supply Mode: Factory direct wholesale, bulk orders preferred, small trial orders (≥100kg) acceptable, OEM/ODM supported

Our products integrate four advanced processes, each step strictly controlled to ensure the perfect presentation of retro aesthetics and practical performance, distinguishing them from ordinary decorative stainless steel sheets:

Adopt advanced vacuum copper plating technology, the copper layer is uniform and dense, with strong adhesion to the stainless steel base, not easy to peel or fall off. The copper layer thickness is strictly controlled to ensure the retro texture of the subsequent blackening antiquing process, while enhancing the decorative value of the product.

After copper plating, professional blackening antiquing treatment is carried out to form a natural, uniform retro patina effect on the surface. The antiqued color is soft and layered, presenting a sense of history and retro elegance, which can perfectly match retro, industrial, and classical decoration styles. The antiqued layer is stable, no fading, and can maintain the retro effect for a long time.

After blackening antiquing, precision brushed treatment is performed with 120#-400# abrasive belts, forming fine and uniform linear texture on the retro surface. The brushed texture enhances the metallic luster of the product, makes the retro color more layered, and effectively covers minor scratches, ensuring the neatness and durability of the surface.

The final step is to apply a transparent anti-fingerprint coating, which is non-toxic, environmentally friendly, and wear-resistant. The coating can effectively prevent fingerprints, oil stains, and dust from adhering to the surface, making daily cleaning simple (only need a dry cloth to wipe), and protecting the copper-plated blackened antiqued layer from damage, extending the service life of the product.

We provide two high-quality ASTM grades, adapting to different decoration environments and quality requirements, ensuring the durability of retro decorative projects:

ASTM 304 is a classic austenitic stainless steel, with excellent atmospheric corrosion resistance, oxidation resistance, and ductility. It is the most cost-effective choice for retro decorative projects, perfectly matching the four core processes, and presenting a high-grade retro effect.

Applicable Scenarios: Indoor retro decoration, hotel lobbies, restaurant decoration, home background walls, furniture accessories, and dry outdoor retro decorative projects.

ASTM 316L is a high-end marine-grade stainless steel, added with molybdenum element, which significantly enhances corrosion resistance, especially in humid, coastal, and slightly corrosive environments. It has better durability and anti-corrosion performance than 304, ensuring the long-term stability of the retro surface in harsh environments.

Applicable Scenarios: Coastal retro building decoration, humid environment decoration (swimming pools, bathrooms), outdoor retro projects, and high-standard luxury retro decorative spaces.

• ✅ Unique Retro Aesthetics: Copper-plated blackened antiqued + brushed finish, natural retro patina, layered texture, perfectly matching retro, industrial, classical decoration styles, enhancing the high-grade sense of the space.
• ✅ Four-in-One Core Processes: Copper plating (adhesive), blackening antiquing (retro), brushed (texture), anti-fingerprint (practical), integrating aesthetics and usability, solving the problem of retro materials being difficult to maintain.
