This 80 x 80 mm metric 40 series square T-slot profile is a large-section aluminium extrusion with eight open T-slots. Because the section is square and the slots are open, connectors, brackets and accessories can be fitted from any side, and a frame can be assembled by cutting bars to length and bolting them together rather than welding. The larger section makes the profile suitable for frames that carry more weight or span a longer distance than a light profile allows.
The metric 40 series uses one slot geometry across the family, so the fittings that suit this profile also suit the rest of the series. That consistency is what turns a single extrusion into a modular frame system.
Choose the section from the load and the span first. A large section resists bending and twisting better than a small one, so it suits long unsupported spans and heavier equipment; where the load is light, a smaller section does the same job at less weight. Confirm the slot width, because it sets which nuts, bolts and brackets can be used.
Next, decide how the frame is put together. Using T-slot connectors keeps the frame adjustable and lets it be taken apart later, which suits equipment that is modified over time. Decide as well whether the profile faces should stay open for future fittings or be closed with covers, and whether the ends need machining for the connections you plan.
Before ordering, confirm the section size, the slot width, the number of open slots and the length of each bar, together with the permitted length tolerance. Confirm the surface finish and whether it must be consistent within the batch, and state any machining requirement such as drilled holes, tapped ends or milled cut-outs.
Finally, confirm the cut accuracy required, because the squareness of the cut ends decides how well the frame sits together, and confirm how each bar must line up with the profiles and plates it joins so that the assembled structure is true.
