Honeycomb Panel Stainless Steel Sheet 201 304 316 430 Series

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.

Structural Superiority and Exceptional Durability

Honeycomb Panels made from stainless steel series 201, 304, 316, and 430 offer a remarkable strength-to-weight ratio. Their unique core structure, bonded between two metal sheets, provides exceptional rigidity and resistance to bending and deformation, outperforming solid sheets of the same weight. This makes them highly resistant to impact and harsh weather conditions, ensuring long-term structural integrity and dimensional stability. The panels are exceptionally flat, minimizing oil-canning effects for a flawless, high-end appearance. This structural efficiency allows for larger spans with less supporting framework, reducing material and installation costs while maintaining superior performance and a modern, sleek aesthetic.

Versatile Material Properties for Diverse Applications

The availability in 201, 304, 316, and 430 series stainless steel ensures a perfect match for any environmental requirement and budget. The 304 series provides excellent all-around corrosion resistance, ideal for most architectural and interior applications. For more demanding coastal or industrial settings, the 316 series offers enhanced protection against chlorides and acids. The 201 series presents a cost-effective alternative for less corrosive environments, while the 430 series provides good resistance to nitric acid and is a practical choice for specific interior or dry exterior applications. This material diversity, combined with a wide range of available surface finishes (e.g., brushed, mirror, colored), grants architects and designers immense creative freedom for facades, cladding, ceilings, and interior feature walls.

Practical Benefits and Sustainable Performance

Beyond their structural and aesthetic appeal, these panels deliver significant practical advantages. Their lightweight nature simplifies handling, transportation, and installation, leading to faster project completion and lower labor costs. The stainless steel surfaces are non-porous, extremely easy to clean and maintain, and highly resistant to vandalism and graffiti. Furthermore, stainless steel is a fully recyclable material, contributing to sustainable building practices and often qualifying for green building certifications. The inherent fire resistance of the stainless steel construction enhances building safety. Combined with their longevity and minimal maintenance needs, honeycomb panels represent a smart, long-term investment that delivers enduring value and performance.
