Product Overview
Our Stainless Steel Strip (also known as stainless steel coil, stainless steel band, or stainless steel foil) is manufactured from premium stainless steel through hot rolling, cold rolling, annealing, and pickling processes. With excellent corrosion resistance, high strength, precise thickness tolerance, and various surface finishes, stainless strips are widely used in automotive, electronics, kitchenware, construction, medical equipment, and general manufacturing. We supply a comprehensive range of stainless steel strips in 304, 304L, 316, 316L, 321, 410, 420, 430, and 201 grades, with custom widths, thicknesses, and surface finishes available.

Key Features & Advantages
- Excellent corrosion resistance – 304/316 grades resist rust, acids, and harsh environments
- Precise thickness tolerance – consistent dimensions for high-speed stamping and forming
- Multiple surface finishes – 2B, BA, No.4, 8K mirror for various aesthetic and functional requirements
- Custom slitting – precise width cutting from 5mm to 1500mm
- Wide hardness range – from annealed (soft) to full hard (spring) for different applications
- Excellent formability and weldability – suitable for deep drawing, bending, and welding
- Large coil weights – reduces downtime and material waste in continuous production
- Full traceability – mill test certificates with heat number, chemical composition, and mechanical properties
Applications
- Automotive components – exhaust systems, trim, gaskets, springs
- Electronics and electrical – connectors, lead frames, battery cases, shielding
- Kitchenware and tableware – sinks, utensils, cookware, appliances
- Construction and architecture – roofing, wall panels, gutters, decorative trim
- Medical equipment and instruments – surgical tools, implants, hospital equipment
- Chemical and petrochemical equipment – tanks, pipes, heat exchangers
- Food processing and packaging – conveyor belts, packaging machinery, food containers
- Precision instruments and watchmaking
- General manufacturing – stamping, deep drawing, laser cutting
- Marine and offshore applications (316L grade)
Quality Control & Testing
Every batch of stainless steel strips undergoes rigorous quality control:
Raw Material: Chemical composition analysis (spectrometer), PMI testing, heat number verification
Process Control: In-line thickness monitoring (gamma ray/X-ray gauge), surface inspection, tension control, annealing temperature monitoring
Finished Product: Thickness measurement (micrometer), width measurement, coil weight verification, surface finish inspection, hardness test (Rockwell/Vickers), tensile test (yield strength, tensile strength, elongation), cupping test (formability), salt spray test (corrosion resistance)
Documentation: Mill Test Certificate (MTC) per EN 10204 3.1, material traceability, conformity certificate
Packaging & Shipping
Packaging: Standard export packaging – coils wrapped with waterproof paper, plastic film, and steel straps; wooden pallets or crates; edge protectors; PVC caps for inner diameter protection; individual wrapping for bright/mirror finishes
