Description

The 42mm x 20mm aluminium flat bar is a heavy-mass, industrial-grade extrusion profile manufactured from EN AW-6063 aluminium alloy in T6 temper. Its substantial 20 mm thickness and expanded 42 mm width provide outstanding compressive strength, dimensional stability, and resistance to mechanical stress—making it ideal for high-load structural and engineering applications.

This profile is frequently used in custom machine bases, precision mounting frames, reinforced tooling systems, and load-distribution plates. The solid geometry offers excellent performance under both static and dynamic loads, making it suitable for vibration-prone environments and large-scale fabrication.

Supplied with a smooth mill finish, this profile can be easily processed using CNC machining, drilling, and cutting. For applications requiring corrosion protection or a refined surface, anodised and powder-coated versions are available upon request.

Each bar is supplied in 6-metre standard lengths. Cut-to-size and surface finishing services can be arranged to meet specific engineering or production requirements.

We supply aluminium flat bars to manufacturers, fabricators, and contractors seeking consistent quality and reliable supply for their operations.

➤ Minimum order quantity: 500 kg.
