Advantages of aluminum extrusion profiles

  • Use: Suitable for various structure of frame combination, such as storage rack, warehouse shelf, instrument rack, display bar, workbench, etc., simple and elegant.
  • Light weight: the density of aluminum is only 1/3 of copper, iron or steel.
  • High strength: Aluminum profiles are treated with both hot and cold processes during the production process, and their strength properties are improved after quenching and Prescription.
  • Corrosion resistance: In most environmental conditions, including air, water (or seawater), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance, even better after anodizing.
  • Aesthetics: Good surface finish and simple and generous appearance.
  • Economical: Aluminum has high recyclability, and the characteristics of recycled aluminum are almost no different from those of virgin aluminum.
  • Safety: compared with other metal materials, aluminum profiles have no metal pollution, no toxicity, and no volatile metals in the surface oxidation layer.

I bought these to make a top-hat for my Voron Trident. There's nothing wrong with the extrusions. Be careful though: The outer dimensions are the same as what you would see from an LDO kit, but the center hole cannot be tapped for M5. You'll have to tap the center for M6. Make sure you have the hardware on hand. Also, these are anodized aluminum with a perfectly reasonable finish, but if you compare it to the finish of your LDO kit you will be disappointed.

Exactly as described. Packaged great and not a scratch on any of them - most had a protective film on multiple sides and they were all wrapped individually in thin, soft packaging foam. They were able to be cut clean and smooth with my normal medium aluminum miter blade. The silver finish is sharp - unlike the black coated profiles, the scratches from normal cutting and building are practically invisible (they also feel smooth, not like a chalk board like the black coated ones).Probably states this in the description, but will verify in case anyone is curious:- These are T-Slot, not V-Slot- End tap is M6, not M5

I recently purchased 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail, and I was able to get an open box set for a great price. The value for this product is excellent, especially if you are collecting extrusions for a build one day.The aluminum extrusions are well-made and durable, with a smooth and consistent anodized finish. They are also very versatile, as they can be used for a variety of projects and applications, from building furniture to creating custom 3D printers.Despite being open box, the extrusions I received were in excellent condition, and they were packaged securely to prevent any damage during shipping.Overall, I would highly recommend 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail to anyone looking for a high-quality and versatile building material. The value is excellent, especially if you can find an open box set for a discount.

Wow, I am impressed with the quality, strength and appearance of these extruded aluminum rails! I am already thinking of other projects to build with these. Highly recommend and will be back to purchase more.

Other reviews already talk to all the positives, so I'll skip that here, but the 200mm extrusions I ordered are not cut perfectly. I bought these to build a frame for a small corexy printer (rook 2020) and I couldn't square it completely when the extrusions are flush against each other.Still leaving a 4 star rating because they are great quality and arrived quickly.

I ordered these to use on a 3D printer. Many times the frame is joined by screwing a M5 screw into the end of the extrusion, which is what I planned. However the hole in the center of these extrusions is 5mm so an M5 bolt fits loosely. I didn't check the drawing before I ordered, and it shows a 5mm hole so it's my fault - not being aware that some extrusions are different. I ended up drilling the hole larger and tapping it for 1/4-20 so I was able to use them

Worked fine for what I needed it for. A bit pricey though.
