stainless steel flat bar
Stainless steel flat bar or “flat stock” is an excellent candidate for most processing techniques and indoor and outdoor applications. This product has a semi-smooth, dull grey finish, and sharply defined edges. With accurate dimensions throughout the length, the stainless steel flat bar is a high-strength material with excellent corrosion resistance. This makes it ideal for shelves, brackets, bracing, sculptures, and other architectural uses. Also found within the food and beverage industry, aerospace applications, and chemical processing.
