Description

The 55.5mm aluminium round bar is a solid, large-diameter rod manufactured from EN AW-6063 aluminium alloy in T6 temper. Its oversized profile provides superior strength, dimensional integrity, and corrosion resistance, making it suitable for structurally demanding and precision-machined applications.

Typical uses include high-load support shafts, custom cylindrical parts, base fixtures, and rotating mechanical components used in industrial equipment, heavy machinery, and architectural systems. The smooth surface finish and excellent machinability allow for reliable CNC operations and secondary processes such as welding or anodising.

Supplied in 6-metre standard lengths with a clean mill finish. Optional powder coating or anodising is available upon request. Project-based cut-to-size services can be arranged for high-volume or custom orders.

Manufactured to tight tolerances, this profile ensures consistent quality across automated and manual fabrication lines.

➤ Minimum order quantity: 500 kg.

➤ Delivery available worldwide via land, sea, or air freight.
