10Pcs V Slot 2020 Aluminum Extrusion Profile 1000mm(39.3'') Black

Very well packaged. Very durable, correct size, no bad cuts, and very well priced compared to other sites. They did come with some oil on them for protection during storage. This is typical of metal materials and easy to clean off. I will be ordering more of these for additional projects.

I’m really impressed with the quality of these Seekliny 2020 Aluminum Extrusion Profiles. I’ve bought rails before that arrived with dinged-up ends or scratches in the finish, but these were packaged well and the black anodizing is flawless across all four pieces. The 600mm cuts are precise and square, which made squaring up my frame a lot easier than I expected. They work perfectly with standard T-nuts and corner brackets, and for the price, it’s a much better deal than buying smaller quantities elsewhere. Definitely a solid choice if you're building a 3D printer or a small CNC rig.

I'm new to 2020 extrusion, but works fine.

The packaging was fine and while there were some shavings, all four sides of the extruded aluminum per piece had a protective film.One thing I noticed was that it's stated that it's anodized but this looks like a raw finish to me without anodizing. I took a picture next to my disassembled S10 Pro (laser engraver) to show the comparison as I'm using it to extend the frame.While it's not a big deal to me, for others, if you're looking for a finished look, it may be a deal breaker as it can scratch easily. Otherwise, the pieces seem nice and straight, and I will update once my upgrade is complete 👍

You know those metal beams that folks use to build 3D printers, CNC machines, or just cool custom stuff? This SeekLiny 10-piece pack of 2020 V-Slot aluminum extrusions is exactly that. They're like the building blocks for all sorts of DIY projects, pretty lightweight but surprisingly strong for their size.They have these V-shaped grooves all along the sides, which are perfect for sliding in nuts and bolts to connect them up however you need. 1 If you're building something that needs a sturdy frame or linear motion (like a camera slider or a simple robot), these are super handy to have around. This pack gives you a good amount to play with for your next project.

These are great. They came with clean cut ends and no damage. Yes there were chips from being cut but 99% of them were stuck to the protective tape that was super easy to remove.

Product arrived when expected, however, product listing stated each piece was 48” in length. Actual measurement was 47”. Would’ve returned the item but that was too much of a hassle

Good value. Clean and very straight. Good value and saved me breaking out the chop saw and aluminum blade to cut down longer lengths. Simplified my build without a lot of extra cost.

Nicely finished and according to specs.

Seekliny is my go-to vendor for aluminum extrusions on Amazon. The price is great and the extrusions are in good quality - always straight and reliable. After some cleaning, the extrusions are good to go. I'm using these to build 3D printers, light stands, robotic applications and even plant supports. I had a problem with sizing because Amazon sent me the wrong size in one of the orders; Seekliny is very helpful and solved the problem quickly after I reached out to them. I'd rate their customer service 5 stars, top tier!

Très bien usinées. Revêtement anodisé de belle qualité et complètement immaculé (protégé pour le transport avec une pellicule plastique).Meilleur prix trouvé!

This is the v slots in order to slide you need other items and not just the bolt.It's wheel that goes attached to this unit 'not the screw kit'Once you put a attachment screw it's meant to stay there.Ppl confuse a lots thinking buying this and the screw to slide 'I repeat the screw kit is not meant to slide or unscrew over and over'

Perfectly straight no scratches, what i expected and they have plastic on every side so they dont scratch each other up however they do have a bitof aluminum dust/bits which is anoying it could be better but its not a huge problem
