When it comes to stainless steel bar tools and industrial equipment, sizes can vary immensely. This is not only dependent on the type of steel used, but also what type of cutting tool it is. hexagonal bar lengths can range from ten to twenty-eight inches (L) or more, while stainless steel bar sizes can be anywhere from six to ten inches (D) wide, six to twelve inches (D) tall, and anywhere from one to three and a half to four hundredths of an inch (H).
