Stainless Steel Finishes: 2B and #4 Options

304 stainless steel is available in two popular finishes that serve distinct purposes:

304 2B Sheet and Coil

This cold-rolled finish features a smooth, matte surface that is ideal for forming and fabrication. 304 2B sheet and 304 2B coil are used widely in industrial, structural, and enclosed applications.

304 #4 Sheet and Coil

This brushed finish is often used in architectural, kitchen, and decorative applications where appearance and scratch resistance are important. 304 #4 coil and 304 #4 sheet provide a sleek, directional grain that enhances visual appeal while maintaining durability.

Reliance Metalcenter offers both finish types in coil, sheet, and plate form and can apply protective PVC coatings to preserve surface integrity during handling or fabrication.
