Product Description
304 stainless steel sheet #4 finish is the brushed finish commonly seen on kitchen appliances and backsplashes. The 304 stainless steel sheet #4 finish has a PVC film on one side to help protect against scratching during fabrication and installation. Our 304 stainless steel sheet #4 finish meets the criteria for both the #3 and #4 finish.
If the 304 stainless steel sheet #4 finish is under 48" long, the customer has a choice on which way the grain of the brushed finish runs (for a 10% extra cost). To choose the direction of the grain, simply put the dimension in the "length" of the cost calculator that you want to have the grain run. For instance, on a 5" by 10" piece that the grain needs to run along the 10" dimension, put the 5" dimension in the "width" of the cost calculator and put the 10" dimension in the "length". Then on fabrication options (step 4), click "Yes" in the grain preference box. This is important if you have multiple pieces and would like the grain to be consistent. If no grain preference is chosen, Stainless Supply will use whatever is the best yield.
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 #4 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 #4 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.
