Heavy-Duty Structural Aluminum Angle Profiles
Heavy-duty 6061-T6 structural angle profiles for load-bearing frames and industrial structures.
Product Overview
When a standard 6063 L-angle isn't strong enough, the structural angle in 6061-T6 is the answer. With a proof stress of 240 MPa — more than twice that of 6063-T5 — the 6061-T6 structural angle can carry loads that would cause a standard angle to yield. This makes it the right choice for load-bearing applications where the angle is a primary structural member, not just a secondary bracket.
Structural angles are used in the construction of industrial shelving systems, mezzanine platforms, equipment support frames, and large conveyor structures. In each case, the angle carries a combination of bending and axial loads that requires the higher strength of 6061-T6. The penalty is slightly higher cost and somewhat reduced extrudability compared to 6063, but for structural applications this trade-off is well justified.
We manufacture structural angles from 40×40mm to 150×150mm, with leg thicknesses from 4mm to 12mm. The larger sizes (above 80×80mm) require our 2,500-ton or 3,600-ton press, and are produced on a scheduled basis rather than from stock. For standard sizes (40×40 to 80×80), we maintain buffer stock and can ship within 5–7 days.
One application that's growing in Southeast Asia is the use of structural aluminum angles for solar panel racking systems. Ground-mount solar installations require structural members that can carry the combined weight of the panels and the wind loads, while resisting corrosion in outdoor environments for 25 years. Structural 6061-T6 angles with AA20 anodizing meet all these requirements, and their light weight compared to steel reduces the foundation loading and installation cost.

Compatibility, Assembly and Order Controls
For modular framing, a nominal outer size is not enough to establish compatibility. Confirm the supplied section drawing, slot geometry, core-hole arrangement, connector family and cut/machining references before a mixed-series order is released.
