Oil Tempered Garage Door Spring

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.

Oil tempered garage door spring. What they are and their pros and cons. The spring wires heat and then bathe in hot oil. First the spring is brought to a high temperature before being quenched in an oil bath. They have been on the market for a very long time and are the torsion springs most garage doors utilize.

After the heating process the oil is slowly cooled to temper the metal. This wire falls into two categories. For example torsion springs used for garage doors lift and lower garage doors that weigh hundreds of pounds. Oil tempered springs have been around for a very long time and they are the most common springs on a garage door.

The difference is that class ii has higher tensile ranges than class i in the same wire size. The wire which is used to make the spring is heated quenched in oil and then heated again. Their name derives from the way they are made. Oil tempered torsion springs offer several unique advantages.

Oil tempered wire mechanical springs and garage door springs are often called upon to do serious heavy lifting. Therefore oil tempered springs remain the most ubiquitous type of torsion spring for the following reasons. Oil tempered springs are then heat treated with a series of heating and cooling phases using hot oil so that they can adequately handle the infrequent stress applications applied to them whenever the door is opened or closed. Oil tempered torsion springs are what we call the classic make for garage doors.

This process makes sure the springs are less prone to damage. Many garage door manufacturers offer this type of spring. Oil tempered garage door springs undergo a unique process to increase their tensile strength without introducing brittleness into the metal. Well to give you an idea about these two types of garage door springs here is oil tempered versus zinc galvanized torsion spring.

Oil tempered springs for both garage door. High durability oil tempered torsion springs are well known for their exceptional durability. These springs however have one downfall. 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.

It s not uncommon for an oil tempered spring under heavy constant use to outlast its zinc galvanized counterpart by a considerable margin. Class i and class ii. Simply put oiled torsion.
