Simply put oiled torsion. The vast majority of garage doors that rely on torsion springs use oil tempered torsion springs by default largely due to their cost and abundant availability. Historically the garage door industry used torsion springs made of oil tempered wire that conformed to astm 229 standards which detail among other things tensile strength ranges by wire size.

These springs however have one downfall. Oil tempered springs have been around for a very long time and they are the most common springs on a garage door.
