What are SS 304 / SS 304L Stainless Steel Channels?
SS 304 is the most widely used austenitic stainless steel, offering a balance of good mechanical strength, excellent corrosion resistance, and ease of fabrication.
SS 304L is the low-carbon version of SS 304, specifically designed to minimize carbide precipitation during welding, making it perfect for welded assemblies and sanitary environments.
Both are available in U-Channels, C-Channels, and custom forms, in equal and unequal flange widths.
