Upgrade your projects with our premium stainless steel tubes—durable, adaptable, and built to last.

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.

Our 201, 304, 430, and 316 stainless steel special-shaped tubes deliver unmatched versatility for demanding architectural, industrial, and decorative applications. Each grade is precision-engineered to offer distinct mechanical and corrosion-resistant properties — 201 for cost-effective durability, 304 for all-around reliability, 430 for magnetic functionality and moderate corrosion resistance, and 316 for superior performance in harsh, chloride-rich environments. Whether you need oval, square, triangular, or custom profiles, our tubes maintain dimensional accuracy and structural integrity under load, heat, or stress.

Manufactured using advanced cold-forming and welding techniques, these tubes feature seamless aesthetics and uniform wall thickness, ensuring smooth surfaces ideal for polishing, coating, or direct installation. The special shapes not only enhance visual appeal in railings, furniture, and fixtures but also improve load distribution and space efficiency in structural frameworks. With strict quality control from raw material selection to final inspection, we guarantee consistency in chemical composition, tensile strength, and surface finish across every batch — minimizing waste and maximizing compatibility with your fabrication processes.

Backed by global certifications and tailored logistics support, our stainless steel shaped tubes offer a future-proof solution for projects requiring both form and function. From coastal installations to high-traffic interiors, they resist rust, staining, and deformation over time — reducing maintenance costs and extending service life. Let our engineering team assist with custom sizing, finishing, or alloy matching to ensure your design vision is realized without compromise, on time and within budget.
