Product Description
304 stainless steel 2B finish is a mill finish, which is smooth and NOT the brushed finish commonly seen on kitchen appliances. 304 stainless steel 2B finish is light gray in color. 304 stainless steel 2B finish may or may not have a protective film on one side to prevent scratching. Customers can contact the sales department to see if the 2B finish has a protective film on the material if needed; however, if a clean, non-scratched finish is desired, the #4 brushed finish will have a protective film every time.
If you need any fabrication (grain preference, hemming, rounded corners), you must select the "cut to your size" option. The maximum thickness of 304 stainless steel sheet 2B finish that we can offer bending is 11 gauge. The maximum thickness of 304 stainless steel sheet metal that we can hem is 20 gauge. If you need a bending option, please see our Angle/Channel section.
304 stainless steel is a commercial grade of stainless steel sheet metal and the most widely used stainless steel. 304 stainless steel sheet metal is a versatile, anti-rusting and heat resistant steel for general use. 304 stainless steel sheet metal uses include food equipment, plumbing materials, kitchen sinks, and back splashes. 304 stainless steel sheet 2B finish is austenitic, meaning it will not attract or hold a magnet. If you need that option in stainless steel, the 430 grade will hold a magnet.
