160160 Heavy-Duty Structural Aluminum T-Slot Profile
160×160mm mega structural profile for large industrial frameworks and heavy machine bases.
Product Overview
There are applications where even the 8080 profile isn't enough. Large robotic welding cells, heavy-duty press frames, industrial test rigs, and large-scale automation systems sometimes demand a structural member that can carry loads measured in tons, not kilograms. The 160160 profile exists for exactly these applications.
At 160×160mm with a wall thickness of 5mm minimum and a weight of 14.8 kg/m, the 160160 is a genuinely structural aluminum section. Its moment of inertia of 1,450 cm⁴ is 18 times that of the 8080 — meaning it can span distances and carry loads that would cause an 8080 to deflect unacceptably. For a 3-meter span carrying a 5-ton distributed load, the 160160 deflects less than 2mm. The equivalent 8080 would deflect over 35mm.
The 14mm T-slots accommodate M12 T-bolts, providing pull-out forces of up to 25 kN per bolt. For structural connections in large machine frames, this means you can design bolted joints that are genuinely structural — not just positional. Combined with internal corner brackets and anchor brackets, the 160160 system can build frames that rival welded steel in stiffness and strength, while remaining fully reconfigurable.
We manufacture the 160160 from 6061-T6 alloy, which provides the tensile strength (260 MPa) and proof stress (240 MPa) needed for structural applications. The extrusion process for this large section requires our 3,600-ton press — our largest — and careful control of the extrusion temperature and speed to ensure consistent mechanical properties throughout the profile length.
Lead time for the 160160 is typically 20–25 working days, slightly longer than smaller profiles due to the production scheduling requirements for our largest press. For large orders (above 5 tons), we recommend placing orders with 4–6 weeks lead time to ensure availability.

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.
