Likewise, what is the difference between treated and pressure treated wood?

Pressure treated lumber is no stronger than untreated lumber. The difference between the two is that pressure treated lumber will resist the elements better than untreated due to chemical preservatives added, and so will maintain its integrity in conditions that would cause normal wood to rot.

Heat treated pallets are resistant to fungi and other microorganisms that would otherwise increase the risks of rotting.
