Aluminium Round Bar 18mm
Description
The 18mm aluminium round bar is a solid, high-strength rod extruded from EN AW-6063 aluminium alloy in T6 temper. With its increased diameter, it provides enhanced rigidity and load-bearing capacity, making it suitable for medium to heavy-duty mechanical and structural applications.
This profile is commonly used in the production of structural pins, motion system shafts, reinforcement rods, and industrial fixtures where strength, machinability, and corrosion resistance are essential. Its consistent surface finish also supports post-processing such as anodising or powder coating.
Each bar is supplied in 6-metre standard lengths with mill finish. Optional coatings and custom-cutting services are available depending on project specifications and order volume.
We support fabricators, OEMs, and industrial clients with reliable aluminium bar solutions optimised for production, assembly, and export logistics.
➤ Minimum order quantity: 500 kg.
➤ Delivery available worldwide via land, sea, or air freight.
