For example, it doesn’t have the best resistance to corrosion, so if you want it to last a long time outside, you’ll probably need to add some protective layers down the line.
Even though A36 beams are still hugely popular today, some engineers are starting to wonder how sustainable they really are in the long run. As technology and materials keep advancing, who knows—maybe someday something new will replace them with even better durability and performance. Still, for now, they remain a go-to choice, but it’s definitely worth thinking about these factors when planning new projects.
