If you are looking for SUS 304 brushed stainless steel flat bars, we offer high-quality flat bars suitable for construction, decoration, and industrial applications. Our SUS 304 flat bars are available in thicknesses ranging from 1 mm to 20 mm and widths from 10 mm to 200 mm, with custom sizes and cutting services available to meet your project needs.
The SUS 304 flat bars feature a brushed surface finish, processed with a precision brushing process, resulting in a surface roughness of Ra≤0.8μm, while maintaining excellent corrosion resistance. This makes them ideal for interior design, kitchen equipment, and marine environments.
Our SUS 304 stainless steel flat bars strictly adhere to the ASTM A276 standard, containing 18.0-20.0% Cr and 8.0-10.5% Ni, with a tensile strength of ≥520MPa, a yield strength of ≥205MPa, and resistance to neutral salt spray corrosion for over 500 hours. Maintenance costs are only 1/5 of those for ordinary carbon steel.
We also provide polishing, cutting, and packaging services, and can provide ISO, SGS, or BV certifications to ensure product quality. We support fast delivery within 7-10 days and provide EN 10204 3.2 material certificates.
