T Slot and V Slot Aluminum Extrusion Profiles from Zetwerk

There are other building materials available in the market like steel for a modular framework like this t-slot extrusion. Steel can be used to form complex cross-section profiles too. But, aluminum-based t-slotted extrusions have numerous benefits over others. Aluminum is lightweight. It is one-third the weight of the steel. When there is a demand for durable and robust products without a massive increase in weight, aluminum is the first choice.

Golden Jash are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Another benefit of using aluminum is its corrosion resistance. The layer of aluminum oxide prevents the reaction between metal and air. Though stainless steel also possesses good corrosion resistance with added chromium to its surface. This corrosion resistance property of aluminum helps reduce maintenance costs. With fewer chances of damage during shipping and storing the material, t-slot aluminum extrusions.

What is T-Slot (V-Slot) and other profiles

T-Slot / V-Slot

T-Slot has been around for many years. It has matured to a solid building system using in industry and by hobby engineers to build everything from machine enclosures to CNC machines, 3D printers and robots! It is strong enough to withstand many industrial stresses and modular enough allow for universal designs.

The T-slot system consists of extruded aluminum of various sizes with a “T” shaped slot on one or more of its sides. The shapes, sizes and designs may be different, but the “T” slot is common to all. The “T” slot allows of a variety of hardware to be connected to the extrusion so that complex structures can be constructed.

 

Types of T-Slot

There are many types of T-Slot available on the market. Some of the most common for small scale engineering include:

  • V-Slot
  • MakerBeam
  • OpenBeam
  • MicoRax

 

As show above, these 4 type range from 10mm to 20mm square profile. Each profile has its unique features, but all share the “T” slot function.

The profiles are not limited to square. V-slot, for example, comes in 4 sizes 20x80mm, 20x60mm, 20x40mm and 20x20mm :

Some manufactures produce larger square and other shaped profiles:

 

MakerBeam can fit a screw into its T-slot:

 

MicroRax is small, light and uses t-nuts and screws:

 

OpenBeam can fit a standard nut into its t-slot:

 

V-Slot uses t-nuts and is different from the other profiles because has “V” grooves that fit special “V” wheels and allow for easy linear motion:

 

Above are four different approaches to T-slot, there are in fact many more.
