Key Features and Benefits

The 201 series provides excellent cost-effectiveness with good corrosion resistance, perfect for budget-conscious projects. The 304 series boasts superior rust resistance and longevity, making it a top choice for high-moisture environments like kitchens and bathrooms. The 430 series offers magnetic properties and reliable performance for functional applications. All series feature a brushed texture that hides fingerprints and scratches, ensuring lasting beauty with minimal maintenance.

Versatile Applications

Whether you’re designing statement furniture, crafting custom appliances, or enhancing interior decor, these plates deliver unmatched versatility. Their aged appearance effortlessly complements various styles, while the stainless steel foundation guarantees strength and reliability. Easy to cut, weld, and shape, they empower creativity without compromising on quality. Upgrade your projects with the timeless appeal and practicality of dark spot brushed aged stainless steel.

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.

Dark spot brass aged stainless steel plates (201, 304, 430 series) offer a rare fusion of vintage elegance and modern durability. The dark spot brass finish delivers an artisanal, timeworn patina that evokes rustic charm and industrial sophistication — perfect for designers seeking character-rich surfaces without compromising structural integrity. Each series brings distinct advantages: 304 excels in corrosion resistance and hygiene, ideal for kitchens, bathrooms, and coastal installations; 201 provides cost-effective strength for interior applications with moderate exposure; 430 offers magnetic properties and heat resistance, suited for appliances and decorative fixtures.

The aged brass texture conceals minor scratches and fingerprints, reducing maintenance while enhancing visual depth over time. Unlike painted or coated alternatives, this finish is chemically bonded to the steel, ensuring longevity and fade resistance under UV exposure or high-traffic use. Architects and fabricators value its versatility — easily cut, welded, or formed without finish degradation.

The dark undertones complement both warm wood accents and cool minimalist palettes, making it a seamless fit for luxury retail, boutique hospitality, or residential statement walls. With sustainable production methods and recyclable base materials, it meets eco-conscious project specifications without sacrificing aesthetics. Whether used for elevator panels, bar fronts, cabinet cladding, or custom furniture, this material transforms ordinary spaces into curated experiences — where history, resilience, and design converge.
