8080 Heavy-Duty T-Slot Aluminum Profile
80×80mm structural profile in 6061-T6 for large machine bases and heavy industrial frameworks.
Product Overview
When you're building a machine base that needs to support a 2-ton press, or a gantry crane that spans 8 meters, the 4040 and 4080 profiles simply aren't in the conversation. You need something fundamentally different — and that's where the 8080 heavy-duty profile earns its place.
The 8080 is made from AA 6061-T6, not the more common 6063. The difference matters: 6061-T6 has a tensile strength of 260 MPa and a proof stress of 240 MPa, compared to 160 MPa and 110 MPa for 6063-T5. That's 60% more strength — enough to allow thinner walls on a large cross-section without sacrificing structural integrity. The result is a profile that's genuinely structural, not just decorative framing.
The 8080 has 8 T-slots — two per face — with a 10mm slot width that accommodates M8 and M10 T-bolts. The larger fasteners provide substantially higher pull-out force: an M10 T-bolt in an 8080 profile can withstand 11.5 kN of pull-out force, compared to 4.5 kN for an M6 bolt in a 4040. For structural connections that carry real loads, this difference is critical.
We see the 8080 used in heavy automation cells in Vietnam's electronics manufacturing sector, in large CNC machine bases in Thailand, and in industrial shelving systems across Indonesia. In each case, the customer chose it because they needed a structure that wouldn't flex, wouldn't loosen over time, and wouldn't require constant re-leveling. The 8080 delivers all three.
One consideration with the 8080 is weight: at 4.22 kg/m, a 6-meter length weighs over 25 kg. For large frames, this means you'll need proper lifting equipment during assembly. We recommend planning the assembly sequence carefully — build the base first, then add vertical columns, then horizontal beams — to avoid having to lift heavy assemblies into position.
Hard anodizing (AA25, 25μm oxide layer) is available for 8080 profiles used in wear-intensive applications such as guide surfaces or sliding interfaces. Hard anodized aluminum has a surface hardness of 400–500 HV, comparable to hardened steel, making it suitable for applications where bare aluminum would wear quickly.

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.
