Choosing Between Steel or Aluminum Structural Framing? Read this.

Choosing Between Steel or Aluminum for Your Machine - Read this - Aluminum IPS Structural Framing - Electromechanical Drives Division - Parker Hannifin CorporationAre you on the fence about structural framing for your machine? Despite the many presentations, articles, and forums that provide helpful pieces of information for engineers approaching this fork in the design road, sometimes it's a good idea to take advice from a trusted partner.

Our purpose in this post is to arm you with more information to make an informed decision between aluminum and steel structural framing.

You have a variety of decisions to make when designing an application. Some of the fundamental decisions involve selecting the type of material needed to build the actual machine; how to enclose or guard the machine; or possibly determining how modular you want to make the machine. Typically, the material selection comes down to two choices: aluminum (t-slot framing) or steel structural framing.

Something important to consider is the total machine cost. Let’s take a few moments to focus on some of the aspects of the total machine cost for aluminum and steel structural framing.

Total machine cost

If you are examining material cost per pound data, then steel structural framing will look very appealing. Aluminum structural framing, per pound, will cost more due to the raw material costs, but let’s consider a few more factors. Although steel structural framing is about 2.5 times denser and is certainly suited for high vibration or heavy load applications, aluminum structural framing can be considered a cost-saving material for several reasons.

Aluminum maintenance savings

  • It's easy to replace a component in an aluminum structural framing system, specifically a t-slot aluminum framed system
  • Inexpensive assembly tools (Allen wrench, screwdriver and, possibly, a mallet)
  • Time is money - you'll complete a t-slot aluminum structural framing design faster than a welded steel design

Aluminum weighs roughly 33% less than steel

  • Reduced processing
  • Lower assembly cost
  • Cost-effective tooling
  • Easier modifications

Aluminum sustainability and longer life

  • Lighter loads require smaller motors and mechanics
  • Longer life and sustainability - More than 75% of the aluminum produced since 1888 is still in productive use today (Source: http://recycling.world-aluminium.org)

These are just some of the value drivers to consider when making a decision on the type of material to use in your structural framing, viewed through the lens of total machine cost.
