1) Steel Rusts…Aluminum Doesn’t

Unlike Steel, which rusts due to the presence of iron in its composition, Aluminum does not rust. When continually exposed to oxygen and water, the surface of steel gradually becomes pale and brown, and it loses its aesthetic value.

Even galvanized steel isn’t completely immune from rusting, as the paint will wear off (especially around the joints) with time due to the effect of weather extremities, thereby only delaying the inevitable. You’ll have no such worries with aluminum.

Aluminum is naturally resistant thanks to the protective layer of aluminum oxide that forms around it when it interacts with oxygen and water. This layer shields the insides while also rendering corrosive elements inert, thereby ensuring the framing retains its visual appeal for years. 

2) Less maintenance

Since it doesn’t splinter, crack, rot, or rust, an aluminum frame requires little to no maintenance work. That saves you both time and money. Steel frames also don’t have too much work save for the periodic painting- particularly necessary in cold climates plagued by snow and ice- which brings labor and material expenses. 

3) Aluminum is lighter

Steel is about two and a half times denser than aluminum, so it makes for a more massive frame that requires some effort to build and repair.  The opposite is the case for the latter, which is light and malleable.

So what will it be?

An aluminum or steel frame, what will it be? Both are solid options and your choice will largely depend on your specific needs and how much you are willing to spend.
