Lightweight PVD Coated Hairline Brass Colored Stainless Steel Sheet 2000mm

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.

Versatility and Aesthetic Appeal

Our Brass Aged Stainless Steel Plates offer a unique blend of timeless aesthetics and modern material science. This collection, available in grades 201, 304, 316, and 430, features a warm, rich brass-toned surface that delivers the luxurious and vintage appeal of aged brass without the maintenance concerns of actual copper alloys. The deep, consistent golden hue is achieved through advanced PVD (Physical Vapor Deposition) coating or electroplating techniques, ensuring exceptional color fastness and resistance to fading. This makes it an ideal, cost-effective solution for architects and designers seeking to create a statement in interior applications such as feature walls, elevator cladding, boutique retail displays, and luxury furniture, providing an instant touch of classic elegance and warmth.

Tailored Performance for Every Application

Beyond its striking appearance, this product line leverages the distinct mechanical and corrosive properties of each stainless steel grade to suit various environments and budgets. Grade 304 offers excellent all-round corrosion resistance, making it perfect for most indoor settings. Grade 316, with its added molybdenum, provides superior resistance to chlorides and is highly recommended for coastal areas or applications requiring enhanced durability. The cost-effective 201 grade is a robust choice for interior decorative projects with less demanding conditions. For primarily indoor, dry applications where form is prioritized over extreme corrosion resistance, the 430 series provides a reliable ferritic option. This strategic selection ensures there is a brass-aged plate perfectly suited for your specific project requirements, balancing performance with cost-efficiency.

Durability and Low Maintenance

The primary advantage of this product lies in its fusion of enduring beauty and the inherent strength of stainless steel. Unlike raw brass, which tarnishes and requires regular polishing, our brass-aged plates are topped with a clear, protective coating. This layer shields the vibrant finish from scratches, fingerprints, and oxidation, ensuring the elegant look lasts for years with minimal upkeep. The substrate stainless steel provides structural integrity, impact resistance, and longevity that far surpasses painted or laminated alternatives. By choosing our Brass Aged Stainless Steel Plates, you invest in a sustainable, durable material that reduces long-term maintenance costs while delivering an uncompromising, sophisticated aesthetic for both residential and commercial projects.
