Black Mirror Stainless Steel Sheet 0.8mm 1.0mm 1.2mm 4ft*8ft Sandblasting, Matte Finish

1. Introduction to Black Mirror Stainless Steel Sheets

2. Production Process

1. Base Material Preparation: Start with high-quality stainless steel coils or plates (e.g., 304, 316L). The base metal is first cleaned via degreasing and pickling to remove oil, rust, or oxide layers—this step is critical to ensure uniform adhesion of subsequent coatings.
2. Mirror Polishing: The cleaned stainless steel surface is polished using abrasive materials (such as diamond pads) and advanced polishing equipment. This process creates a smooth, reflective surface with a high glossiness (typically 8K or higher, meaning it reflects up to 80% of light, comparable to a glass mirror).
3. Black Coloring Treatment: Two primary methods are used to achieve the black finish, both ensuring color fastness and corrosion resistance:
   • PVD (Physical Vapor Deposition): Under high vacuum and controlled temperature, metallic compounds (e.g., titanium nitride, chromium nitride) are vaporized and deposited onto the polished stainless steel surface. This forms a thin (nanometer-scale) black film that bonds tightly with the base metal, offering excellent scratch resistance and resistance to fading from UV exposure.
   • Electrolytic Coloring: The polished sheet is immersed in an electrolyte solution, and an electric current is applied to form a black oxide or chromium-rich film on the surface. This method is cost-effective and produces a uniform color.
4. Sandblasting for Matte Finish: For the specified matte effect, the colored mirror surface undergoes sandblasting. High-pressure air propels fine abrasive particles (e.g., aluminum oxide, silicon carbide) onto the sheet, creating a subtle, non-reflective texture that reduces glare while preserving the black hue.
5. Quality Inspection & Cutting: The finished sheets are inspected for surface uniformity, color consistency, and thickness accuracy. They are then cut into standard 4ft*8ft sizes (or custom dimensions per order) and packaged to prevent scratches during transportation.

3. Common Grades & Specifications

Common Stainless Steel Grades

Standard & Custom Specifications

• Thickness: The listed 0.8mm, 1.0mm, and 1.2mm are popular for decorative uses. Other common thicknesses include 0.5mm (ultra-thin, for lightweight designs) and 1.5mm–3.0mm (for heavy-duty applications like door panels).
• Size: 4ft8ft (1220mm2440mm) is the global standard. Custom sizes (e.g., 4ft10ft, 5ft10ft) or cut-to-size pieces are available for specific projects.
• Finish: As specified, the product offers a sandblasted matte finish; other finish options are detailed in Section 4.

4. Other Surface Finishes

• 8K Mirror Finish: The classic "mirror" effect with ultra-high glossiness (8K), ideal for creating a luxurious, modern look in high-end spaces (e.g., hotel lobbies, retail storefronts).
• Brushed Finish: A linear, satin-like texture created by mechanical brushing. It hides fingerprints well and is commonly used for kitchen backsplashes, elevator doors, and furniture handles.
• Hairline Finish: A finer version of the brushed finish, with extremely thin, subtle lines. It adds a delicate, sophisticated touch to decorative elements like cabinet doors or wall accents.
• Etched Finish: Intricate patterns (e.g., geometric designs, logos) are etched onto the black mirror surface using chemical or laser techniques. This is popular for custom signage, art installations, or branded interior decor.

5. Applications

1. Architectural & Interior Decoration

• Wall panels, ceiling tiles, and column cladding in hotels, restaurants, and luxury residences (the matte finish reduces glare in well-lit spaces).
• Elevator cabins, door frames, and handrails (corrosion resistance ensures long-term beauty in high-traffic areas).

2. Furniture & Appliances

• Tabletops, cabinet doors, and drawer fronts for modern kitchens and bathrooms (304 grade resists moisture and stains).
• Panels for refrigerators, ovens, and smart home devices (the black finish complements contemporary appliance designs).

3. Commercial & Retail

• Display stands, store fixtures, and signage in malls, boutiques, and electronics stores (the sleek surface highlights products).
• Kiosk exteriors and reception desks (durable enough to withstand daily use and easy to clean).

4. Outdoor & Specialized Uses

• Facades, canopies, and outdoor railings in coastal or urban areas (316L grade resists rain, salt, and air pollution).
• Medical equipment casings and laboratory countertops (non-porous surface prevents bacterial growth and is easy to sanitize).
