201 304 430 Hand-made Random Pattern Nano Matte Stainless Steel Plate

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.

Distinctive Aesthetics and Texture
This hand-made random pattern nano matte stainless steel plate sets a new standard for visual and tactile appeal. Each sheet features a unique, non-repeating design crafted through artisanal techniques, ensuring that no two installations are identical. The nano-level matte finish delivers an exceptionally smooth, refined surface that resists fingerprints and minimizes visible smudges, making it ideal for high-end architectural and interior applications. The subtle, low-reflective surface enhances depth and character while complementing various design styles—from industrial to luxury minimalist. Its custom, organic appearance provides a sophisticated alternative to generic, machine-rolled metals, allowing designers to create one-of-a-kind spaces with enduring elegance.

Exceptional Durability and Ease of Maintenance
Engineered for long-term performance, this stainless steel plate offers superior resistance to corrosion, abrasion, and everyday wear. The nano-matte coating not only enhances its aesthetic qualities but also strengthens the surface against scratches, moisture, and chemical exposure. Unlike conventional finishes, it maintains its appearance over time with minimal upkeep—simple wiping with a damp cloth is sufficient for cleaning. This makes it a practical choice for high-traffic areas such as commercial buildings, kitchens, elevators, and public installations. Additionally, the material retains its structural integrity under varying temperatures and environmental conditions, ensuring lasting beauty and functionality.

Versatile Material Options and Broad Applicability
Available in grades 201, 304, and 430, this stainless steel plate provides flexibility to meet diverse project requirements and budgets. Grade 304 excels in environments requiring high corrosion resistance, while grade 430 offers excellent value with reliable performance in indoor settings. Grade 201 serves as a balanced, cost-effective solution for decorative applications. The combination of hand-crafted artistry and advanced nano-technology ensures consistent quality across all variants. Suitable for wall cladding, furniture, signage, and custom fixtures, it empowers architects and designers to incorporate stainless steel’s inherent strength and sophistication into a wide array of creative and functional projects.
