Hey DIYers and makers! If you're building a 3D printer, CNC machine, or any custom frame, these aluminum extrusions are super handy. You get two black anodized T-slot profiles, each 580mm long (about 22.83 inches), with a cross-section of 30mm x 150mm. They’re made from 6063-T5 aluminum alloy, so they’re strong, corrosion-resistant, and have a smooth, burr-free finish. The T-slot design lets you easily attach brackets, panels, or other components using standard fasteners—perfect for building sturdy frames, workbenches, shelves, or automation equipment. These are European standard 30 series profiles, widely compatible with lots of hardware out there. Plus, the seller offers customization like cutting, drilling, or threading if you need something special (they can even do lengths up to 6 meters!). Whether you're a hobbyist or a pro, these extrusions give you a solid foundation for all sorts of projects. And if you have any issues, their customer service is quick to help. Grab this 2-pack and start building something awesome!
