These lengths of PG20 Profile T-Slot Aluminium Extrusion are 20x80mm with 8 T-Slots along the sides and 2 T-Slots on the top and bottom, designed for light to medium weight applications. They are made specifically for DIY shelving, prototyping, CNC machines and assembly-line structures, as well as a host of other applications that require impressive structural integrity at a reasonable price with modular functionality.

 The modular design, along with all of the corner brackets and other peripherals, make these extrusions ideal for Mechanics Prototyping, and the T-Slots can even accommodate Delrin Wheels and other rollers. This makes them perfect for building prototypes before committing to a final design with specially-made extrusions, although they are often used as an inexpensive solution to building permanent or semi-permanent structures.

Note: Price is listed per meter.


Cutting/Shipping Policy:

  • For Aluminium Extrusions, linear shafts and Threaded Rods, the maximum length we can ship is 1 meter.
  • Should you require your rod/extrusion cut down to size, we offer a maximum of two cuts per meter, all done within a ±1mm tolerance (stipulate the lengths required in the comments section when checking out).
  • Bear in mind that the width of the cutting blade is 3mm, so each cut will essentially reduce the overall length by 3mm. E.g. One cut will result in two parts with a total length of 997mm, whereas two cuts will result three parts with a total length of 994mm.

Typical Applications for T-Slot Aluminium Extrusions with 20x80mm PG20 Profile:

These PG20 Profile 20x80mm T-Slot Aluminium Extrusions are a great investment if you’ve been eager to build your own structures like shelving or enclosures, and offer the perfect balance of strength, reliability and affordability. In fact we use similar, albeit slightly weaker, Aluminium Extrusions for making our 3D Printer Enclosures, and we have never broken a single one in our workshop – despite rigorous tests and even a few attempts at forcefully breaking them. This is why we are able to guarantee the reliability of all of the extrusions we stock, especially these 20x80mm extrusions which offer double the structural strength.

Whether you are building shelving to hold stock or machines, creating production-line conveyors to carry products through a warehouse, or are keen to build any other types of light to medium weight structures, our range of aluminium extrusions are a smart choice.
