Builders grab steel flat bars for their versatility, shimming doors, building shelves, or reinforcing concrete. Melsteel stocks these flat, rectangular profiles in primed, galvanised, and black finishes, ready for your Melbourne project. This guide lists sizes, uses, and how Melsteel delivers exactly what you need.
Standard Steel Flat Bar Sizes at Melsteel
Flat bars come in Width x Thickness (e.g., 50x5mm), typically 6m lengths. Melsteel cuts to size and offers popular grades like mild steel.
Galvanised options available for outdoor durability, view Melsteel flat bar stock.
Pick the Right Size for Your Build
You select 25x3mm for fine adjustments like door frames or light edging. Builders choose 50x6mm for concrete reinforcement where it anchors mesh securely. For shelves or walkways, 75x8mm or 100x10mm handles foot traffic without flexing.
Pro tip: Thicker bars (10mm+) resist bending; wider ones spread loads.
