304SUS 316SUS Stainless Steel Honeycomb Core Panel Plate Lightweight

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.

The primary advantage of our 201, 304, 316, and 430 Series Honeycomb Panels lies in their exceptional strength-to-weight ratio and structural integrity. The unique honeycomb core structure, bonded between two stainless steel sheets, creates a remarkably rigid and stable panel that resists bending and buckling under pressure. This design allows for significant weight savings compared to a solid plate of equivalent strength, leading to easier handling, lower transportation costs, and reduced structural support requirements. Despite being lightweight, these panels offer outstanding impact resistance and load-bearing capacity, making them an ideal material for applications where both durability and weight are critical factors, such as in architectural cladding, vehicle bodies, and industrial machinery.

Beyond their structural prowess, these panels offer superior durability and tailored corrosion resistance to suit various environments and budgets. The 304 series provides excellent all-around corrosion resistance, making it a versatile choice for most interior and exterior applications. For more demanding settings like coastal areas or chemical processing plants, the 316 series, with its molybdenum content, offers enhanced protection against chlorides and acids. The 430 series provides good resistance to nitric acid and organic chemicals, serving as a cost-effective option for specific indoor uses, while the 201 series offers a balanced performance for general purposes. This range ensures you can select the optimal material for your specific environmental challenges without over-specifying.

Finally, our stainless steel honeycomb panels deliver significant functional and aesthetic benefits. The core acts as an effective thermal and acoustic insulator, contributing to energy efficiency and noise reduction in buildings and vehicles. The non-porous, smooth surface of stainless steel is easy to clean and maintain, ensuring long-lasting hygiene and a modern, professional appearance. Available in various finishes—from brushed and mirror to colored PVDF coatings—the panels offer immense design flexibility. Combined with their inherent fire resistance and longevity, these advantages make the 201, 304, 316, and 430 Series Honeycomb Panels a smart, sustainable, and high-performance solution for a wide array of industrial and architectural projects.
