Round Bar - Half Round Bar: 5/8" Outside Diameter - 6061-T6 Aluminum Product Information

Aluminum Half-Round Bars feature a solid semi-circular profile designed for both structural support and architectural finishing. Often specified as half-round aluminum trim or semi-circular aluminum bar stock, these extrusions combine durability with a refined, finished appearance.

The flat back surface allows for secure mounting to panels and substrates, while the rounded face provides smooth edge protection and a clean visual transition. Half-round bars are widely used in trim, edging, transitions, and custom fabrication projects.
