What Is Stainless Steel Flat Bar?
Product Definition:
Stainless steel flat bars are long structural products with a rectangular cross-section, consisting of a width greater than the thickness. This simple yet versatile design provides excellent strength and stability, making flat bars the preferred choice for structural framing, brackets, supports, reinforcements, and decorative applications in construction, industrial, and architectural projects.
Specification Notation:
Stainless flat bars are specified by (thickness)× (width) in millimeters.Example: 5×40mm = flat bar with 5mm thickness and 40mm width
Example: 10×100mm = flat bar with 10mm thickness and 100mm width
