Round Bars
Aluminum Round Bars and Half-Round Bars are versatile solid aluminum profiles used in structural, machining, and architectural applications. These extrusions provide reliable strength, corrosion resistance, and clean surface finishes for a wide range of fabrication and design needs.
Round bars, also known as aluminum rods, feature a full cylindrical profile ideal for machining, shafts, spacers, and structural components. Half-round bars combine a flat mounting surface with a rounded face, making them well-suited for trim, edge protection, and decorative applications.
Manufactured from corrosion-resistant aluminum alloy, these profiles offer excellent strength-to-weight ratio while remaining easy to cut, drill, tap, and machine. Aluminum round and half-round bars are commonly used in construction, manufacturing, architectural systems, and custom fabrication projects.
