Brushed Green Antique Bronze Colored Stainless Steel Sheet 201 304 316 430

The production of colored stainless steel sheets via PVD (Physical Vapor Deposition) involves three core stages: pre-treatment, PVD coating deposition, and post-treatment, with strict parameter control throughout.

This stage ensures a clean, smooth surface for coating adhesion.

Cutting & Polishing: Cut stainless steel coils/plates to required dimensions via laser or shearing. Polish with abrasive belts/wheels to achieve finishes like mirror, brushed, or matte, and remove minor scratches.

Cleaning: First, degrease with alkaline/solvent solutions to eliminate oil and fingerprints. Then, pickle with nitric-hydrofluoric acid to remove oxide layers and polishing residues. Finally, rinse with deionized water and dry with hot air/infrared to avoid water spots.

Completed in a high-vacuum chamber to ensure coating quality.

Vacuum Setup: Load dried substrates into the chamber, then pump to 10⁻³–10⁻⁵ Pa (high vacuum). Heat substrates to 150–300°C and use argon ion bombardment for deep cleaning.

Target Sputtering & Reaction: Select targets based on color (e.g., titanium for gold, chromium for silver). Use magnetron sputtering (plasma bombards targets to release atoms) or arc ion plating (electric arc melts targets) to vaporize targets. Introduce reactive gases (nitrogen for nitrides, oxygen for oxides); target atoms react with gases to form colored compound films (e.g., TiN for rose gold) on substrates.

Thickness Control: Monitor via a quartz crystal sensor to keep coating thickness at 0.1–1 μm (too thin = poor fastness; too thick = brittleness).

This stage enhances performance and ensures compliance.

Cooling & Finishing: Cool the chamber to room temperature, release vacuum, and unload. Optionally, lightly polish coated surfaces for better gloss.

Quality Checks: Test coating hardness (≥2000 HV via Vickers tester) and adhesion (no peeling via cross-cut tester). Use a spectrophotometer to verify color consistency (ΔE ≤ 1 vs. standards).

Packaging: Wrap qualified sheets in anti-scratch film, then pack in cartons/wooden pallets for transport.

Superior Aesthetic Appeal and Versatile Finishes

Our Brushed Green Antique Bronze stainless steel plates offer a uniquely sophisticated and elegant appearance, blending the rich, earthy tones of antique bronze with a subtle green patina and a low-reflectivity brushed texture. This distinctive finish provides a timeless, vintage charm that is highly sought after for architectural and design applications. It effectively conceals minor fingerprints and scratches, maintaining a consistently beautiful surface with minimal upkeep. This aesthetic versatility makes it an ideal choice for a wide range of projects, from classic and traditional designs to modern and eclectic spaces, enhancing interiors and exteriors with a touch of organic, artisanal character across all available grades—201, 304, 316, and 430.

Enhanced Durability and Corrosion Resistance for Diverse Environments

The core advantage of this product lies in the inherent properties of the different stainless steel substrates. Each grade is selected to meet specific performance needs. Grade 304 offers excellent all-around corrosion resistance, suitable for most indoor and general atmospheric conditions. For more demanding environments, such as coastal areas or those with exposure to de-icing salts, Grade 316 provides superior pitting resistance. Grade 201 represents a cost-effective solution for interior applications with less aggressive conditions, while Grade 430 offers good resistance to atmospheric corrosion and is a stable base for the finish. The PVD (Physical Vapor Deposition) coating process used to create the Green Antique Bronze color is exceptionally durable, ensuring the vibrant hue is resistant to fading, tarnishing, and wear, guaranteeing long-term performance.

Exceptional Value and Practical Application

By offering this premium finish across four steel grades, we provide unparalleled flexibility and value, allowing you to select the perfect balance between performance and budget without compromising on the desired aesthetic. This material is not only visually striking but also highly functional. It is easy to fabricate, clean, and maintain, resisting the need for frequent polishing. Its durability translates into a lower total cost of ownership over the lifespan of a project. This combination of beauty, strength, and practicality makes it an outstanding choice for architects, designers, and fabricators working on applications including elevator cladding, feature walls, column covers, furniture, signage, and luxury retail fixtures.
