Aluminium Flat Bar 40mm x 5.5mm
Description
The 40mm x 5.5mm aluminium flat bar is a solid and dependable extrusion profile made from EN AW-6063 aluminium alloy in T6 temper. Its 40 mm width combined with a reinforced 5.5 mm thickness delivers excellent mechanical strength, impact resistance, and surface alignment—making it suitable for structural applications across construction, fabrication, and machinery sectors.
This profile is often selected for use in load-distribution brackets, base plates, rigid mounting supports, and architectural detailing where a balance of strength and manageable weight is essential. The added thickness offers improved stiffness and minimal deflection, especially in dynamic or high-contact assemblies.
Supplied with a clean mill finish, this flat bar is fully compatible with CNC machining, milling, and mechanical fastening processes. It can also be anodised or powder coated to meet project-specific requirements for corrosion resistance or colour finish.
Each bar is supplied in 6-metre standard lengths. Cut-to-size and surface finishing services are available for production runs and project-based needs.
We supply aluminium flat bars to manufacturers, fabricators, and contractors seeking consistent quality and reliable supply for their operations.
➤ Minimum order quantity: 500 kg.
