201 304 316 Brushed Stainless Steel Sheet Metal PVD Coated In Bulk

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.

The primary advantage of our Brushed Red Bronze Stainless Steel Plates lies in their exceptional and versatile aesthetic appeal. This unique finish combines the warm, rich tones of red bronze with the sophisticated, low-luster texture of a brushed surface, creating a visually striking material that stands out from standard metallic finishes. This collection offers this premium look across four key stainless steel grades: the cost-effective 201, the versatile 304, the corrosion-resistant 316, and the value-oriented 430. This allows designers and architects to select the perfect underlying material for their project's specific requirements without compromising on the desired high-end, contemporary appearance. It is an ideal choice for creating statement pieces in interior design, luxury retail spaces, and modern architectural cladding.

Beyond its captivating appearance, this product line is engineered for superior performance and remarkable durability. The PVD (Physical Vapor Deposition) coating process used to create the Red Bronze finish is highly durable, offering excellent resistance to fading, scratching, and wear, ensuring the vibrant color lasts. The underlying stainless steel substrates provide their inherent strengths: 304 offers excellent general corrosion resistance, 316 provides enhanced protection against chlorides and acidic environments, and 430 delivers good resistance to organic acids. The brushed surface also helps to conceal minor fingerprints and scratches, making it a practical choice for high-traffic areas and applications requiring frequent cleaning.

Finally, these plates offer outstanding application flexibility and long-term value. Available in multiple series, they provide solutions for diverse budgets and performance needs, from interior decorative panels, elevator cladding, and furniture to exterior architectural features in moderately corrosive environments. The combination of a durable, low-maintenance finish with the structural integrity of stainless steel reduces the need for frequent replacement or refinishing, lowering the total cost of ownership. This makes the Brushed Red Bronze collection not just a visually compelling choice, but also a smart, economical, and reliable solution for projects demanding a perfect blend of aesthetics, functionality, and longevity.
