304 Stainless Steel Coil No.4 Finish

304 Stainless Steel Coil No.4 Finish features a uniform, fine, short, straight, parallel brushed texture. Its low reflectivity and excellent fingerprint resistance meet the durability requirements of industrial applications while aligning with modern aesthetic trends, perfectly balancing aesthetics and practicality. It is directly adaptable to batch engineering projects and precision machining needs.

Corrosion-resistant and durable, suitable for multiple scenarios: The 304 stainless steel base combined with the No.4 brushed finish offers excellent resistance to moisture, acid, and alkali corrosion. Its non-porous structure prevents bacterial growth, ensuring long-term colorfastness, no deformation, and no rust. Suitable for various demanding applications including indoor and outdoor use, food contact, and medical applications, its lifespan far exceeds that of ordinary stainless steel products.

Easy to clean and maintain, reducing maintenance costs: The matte brushed texture effectively hides fingerprints, stains, and minor scratches. Daily cleaning is simple; wiping with water is sufficient to keep it clean, significantly reducing maintenance costs in commercial applications and post-project maintenance, making it especially suitable for high-frequency use areas.

Easy to clean and maintain, reducing maintenance costs: The matte brushed texture effectively hides fingerprints, stains, and minor scratches. No complex cleaning is required daily; wiping with water is sufficient to keep it clean. This significantly reduces maintenance costs in commercial applications and post-project maintenance, making it particularly suitable for high-frequency use areas.

Processable and adaptable to diverse needs: It possesses excellent bending, stamping, and welding properties, with no reduction in rust resistance after welding. The brushed texture is continuous and uninterrupted, allowing for direct secondary processing such as laser cutting, bending, and polishing. It is suitable for sheet metal processing, product casings, and decorative styling.

High-end texture, combining aesthetics and practicality: The uniform and delicate short-straight brushed texture offers a low-key and elegant visual appeal. The matte finish is not glaring, enhancing the sophistication of commercial spaces and architectural decorations while avoiding the drawbacks of mirror finishes, such as easy scratching and glare. It suits various styles, including modern minimalism and high-end light luxury.

Q1: What is the core difference between 304 stainless steel coil No.4 Finish, 2B finish, and mirror finish stainless steel coils?

A1: The core difference lies in the surface treatment process and visual and performance characteristics: No.4 features a 180-320 mesh brushed finish, presenting a matte short-straight texture with medium reflectivity. It is fingerprint-resistant, easy to clean, and balances decorative and practicality. 2B is a cold-rolled annealed surface with a matte silver-white finish and no additional brushing treatment. It is less expensive but less decorative. The mirror finish has a high-gloss polished finish with extremely high reflectivity, making it visually appealing but prone to scratches and requiring high maintenance costs. It is suitable for scenarios with extremely high visual brightness requirements.

Q2: Does this product meet food contact safety requirements? Can you provide relevant certifications?

A2: Absolutely. The 304 stainless steel meets food contact grade standards (FDA certified). The No.4 brushed surface is smooth and burr-free, with no unsanitary corners, making it easy to clean and less prone to bacterial growth. It is widely used in food processing equipment and the catering industry. Material testing reports, FDA certification, SGS test reports, and other relevant documents can be provided to ensure product compliance.
