201 304 430 316 SS Stainless Steel Coil Narrow Strip For Architectural Detailing

Premium Stainless Steel Narrow Strips 

Ideal for precision applications, our stainless steel narrow strips are available in grades 201, 304, 430, and 316. Each grade offers unique properties to meet diverse industrial needs, combining durability, corrosion resistance, and versatility. These strips are manufactured with strict quality control, ensuring consistent thickness, smooth edges, and reliable performance in demanding environments.  

Key Features and Applications  

Grade 201 provides excellent formability and is often used in decorative trims, kitchenware, and automotive accessories. Grade 304 offers superior corrosion resistance, making it suitable for food processing, chemical equipment, and architectural detailing. Grade 430, with its heat and oxidation resistance, is ideal for appliances, signage, and automotive exhaust systems. Grade 316 excels in harsh conditions, including marine and chemical environments, due to its enhanced molybdenum content.  

Why Choose Our Strips?  

Our narrow strips are precision-cut, easy to fabricate, and available in custom sizes to fit specific project requirements. They deliver long-lasting performance, cost-effectiveness, and aesthetic appeal. Whether for manufacturing, construction, or DIY projects, these strips provide a reliable solution for high-precision applications.

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.

Engineered for durability and precision, our Stainless Steel Narrow Strip in grades 201, 304, 430, and 316 delivers unmatched performance across diverse industrial applications. Each alloy is cold-rolled to exacting tolerances, ensuring consistent thickness and edge quality for seamless integration into automated manufacturing lines. Grade 304 offers excellent corrosion resistance for food processing and architectural trim, while 316 provides superior chloride resistance for marine and chemical environments. Grade 430 delivers magnetic properties and moderate corrosion resistance ideal for appliances and automotive trim, and economical 201 serves well in mildly corrosive, non-critical applications.

Beyond material versatility, our narrow strip is optimized for fabrication efficiency. With widths customizable down to 3mm and surface finishes ranging from 2B to BA and hairline, it meets the most demanding aesthetic and functional requirements. Enhanced formability and minimal burring reduce tool wear and scrap rates, accelerating production cycles without compromising structural integrity. Whether you’re stamping, bending, or laser-cutting, our strip maintains dimensional stability under stress — a critical advantage for high-volume precision components in electronics, medical devices, and fasteners.

Backed by ISO-certified production and rigorous quality control, every coil is traceable and tested for tensile strength, hardness, and chemical composition. We offer JIT delivery and global logistics support to minimize downtime and inventory costs. From prototyping to mass production, our stainless steel narrow strip combines material science, manufacturing excellence, and customer-centric service — empowering your innovation with reliability you can count on, coil after coil.
