describe the image Versus Steel Frame

80/20 Aluminum Extrusion offers a large list of advantages when compared to steel.  The light to heavy-duty material can be used in applications ranging from a television stand to a machine frame.  You are only held back by your imagination. 

Reduced Fabrication Time and Cost

When you receive the material it is pre-cut and lable corresponding directly to the bill of materials and tagged isometric drawing.  Both are HUGE factors in reducing fabrication time and cost of labor.  The aluminum frame is a cost-effective solution that can save you 25%.

Fabrication Process and Tools

The welding process not only has more steps, but it also requires you to have many different tools.  How many tools do you need when assembling t-slotted aluminum extrusion? No more than five.  After you have completed the assembly, there is no need to paint.  80/20 aluminum extrusion comes with a clear anodize finish.


You have just finished the tedious process of cutting, welding, cleaning, and painting your steel from and your customer wants to make a change.  The customer wants to add another horizontal cross piece.  Not only doesn't it drive up the cost of the project, but you have to go through the whole time consuming process again.  Now, lets substitute the welded steel frame with the 80/20 aluminum extrusion.  Material arrives pre-cut, all you need to do is assemble it. Done.  Change request? No need to worry thanks to the modular design of t-slotted aluminum extrusion.  All you have to do is order the precut piece and hardware then attach it by tightening a few screws.  No welding or painting.
