Perfect for luxury interior design, signage, automotive trim, kitchen backsplashes, and artistic installations. Whether for commercial or residential use, this coil provides a sleek, modern look that enhances any space.

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.

Crafted for brilliance and durability, our 201/304/430/316 Mirror Stainless Steel Coil delivers a flawless reflective surface that enhances both aesthetics and functionality. Ideal for architectural cladding, luxury appliances, and decorative interiors, each grade is precision-polished to a mirror finish that resists fingerprints and smudges while maintaining its luster under daily wear. The 304 and 316 variants offer superior corrosion resistance, making them perfect for coastal or high-humidity environments, while 201 and 430 provide cost-effective brilliance for indoor and moderate-exposure applications.

Engineered for versatility, these coils are available in multiple thicknesses and widths to suit custom fabrication needs—from elevator panels to kitchen backsplashes and retail displays. Our advanced rolling and annealing processes ensure uniform grain structure and consistent reflectivity across every meter, eliminating visual distortion. The mirror surface not only elevates design but also simplifies maintenance, requiring only mild cleaning to restore its showroom shine. Whether you’re crafting modern minimalist spaces or opulent statement pieces, this coil delivers unmatched visual impact with structural reliability.

Backed by strict quality control and international certifications, our stainless steel coils guarantee performance across industries—from hospitality and transportation to medical and food service. The 316 grade meets stringent hygiene standards, while 430 offers magnetic properties useful in specialized engineering. With rapid global delivery and custom-cut options, we ensure your project stays on schedule without compromising on finish or function. Choose our mirror-finish coil for a seamless blend of elegance, endurance, and engineered excellence that turns surfaces into statements.
