Aluminium U Channel 40.6mm x 40.6mm x 3mm
Description
The 40.6mm x 40.6mm x 3mm aluminium U channel is a heavy-duty, equal-leg profile extruded from EN AW-6063 alloy in T5 temper, providing excellent corrosion resistance, high rigidity, and a smooth surface finish. Its equal 40.6 mm base and leg dimensions deliver substantial coverage, while the thick 3 mm wall ensures exceptional strength for demanding structural and framing applications.
This profile is ideal for industrial framing, reinforced edging, architectural trim, and heavy-duty panel support in both commercial and outdoor environments. It can be cut, drilled, and machined with ease to meet specific fabrication requirements.
Supplied in 6-metre standard lengths with a smooth mill finish, anodising or powder coating is available for enhanced surface durability and visual appeal.
➤ Minimum order quantity: 500 kg.
➤ Worldwide delivery via road, sea, or air freight.
