Aluminium Flat Bar 20mm x 5mm (r: 2.5mm)
Description
The 20mm x 5mm aluminium flat bar with a 2.5 mm corner radius is a solid, heavy-duty extrusion profile made from EN AW-6063 aluminium alloy in T6 temper. Designed for structural integrity and visual smoothness, it combines substantial load-bearing strength with a refined edge profile—making it ideal for applications where both performance and appearance matter.
This profile is widely used in reinforced support systems, machine base plates, bracket fabrication, architectural trims, and industrial framing. The 5 mm thickness ensures outstanding rigidity, while the 2.5 mm corner radius improves handling safety and surface treatment uniformity, especially in powder coating and anodising applications.
Its smooth mill finish and dimensional precision make it fully compatible with CNC machining, drilling, milling, and cutting operations. Optional finishing services and custom lengths are available to meet specific production requirements.
Supplied in 6-metre standard lengths. Cut-to-size service is available upon request for volume orders.
We supply aluminium flat bars to manufacturers, fabricators, and contractors seeking consistent quality and reliable supply for their operations.
➤ Minimum order quantity: 500 kg.
➤ Worldwide delivery via road, sea, or air freight.
