Garage door springs work hard to make your door open and close many times each day. When a spring breaks, you need to replace it right away. It’s hard to know what type of spring to install for your door.
Oil-tempered and zinc galvanized springs both have plenty to offer your door. Before you buy, there are a few things to consider. Here’s a look at each one and what you need to know.
The Purpose of Garage Door Springs
Garage door springs keep your door from falling during the opening and closing cycles. The great thing is they also make the door lift enough for you to manually opening and close. It’s very dangerous if the springs break. A professional can help you replace them when this happens.
Oil Tempered VS. Zinc Galvanized Springs
Oil Tempered Springs
These types of springs are actually torsion springs that undergo a process to strengthen them. The spring wires heat and then bathe in hot oil. After the heating process, the oil is slowly cooled to temper the metal. This process makes sure the springs are less prone to damage.
Many garage door manufacturers offer this type of spring. They are more available and cost less to make. They are very durable and long-lasting.
Zinc Galvanized Springs
Zinc galvanized springs are another type of torsion spring. They go through a process similar to oil tempered springs except for a few differences. Rather than being dipped in oil, these springs bathe in high heat molten zinc. After they come out of the bath, oxygen hits them. The oxygen shapes them into zinc oxide and eventually a zinc carbonate. This process leaves behind zero residues which makes them almost rust-free.
Oil tempered springs don’t last a long as zinc galvanized springs but they do keep their strength a bit longer. There are people who choose zinc galvanized springs since they’re most resistant to rust. That is why they usually last longer than oil tempered springs.
The process for oil tempered springs keeps the moisture in. For this reason, they are more prone to rust.
If you don’t like a noisy garage door, you may not want to install the zinc galvanized springs. They tend to make more noise during opening and closing cycles.
If you install the oil tempered springs, keep in mind that they’re messy. Due to the oil dipping process, they leave residue behind. If you install this type, make sure you wear gloves.
Adjusting the Springs
Both of these types of springs have adjustment requirements. The zinc galvanized springs need frequent adjustments because they lose their strength quicker than oil tempered springs.
Oil tempered springs typically cost less to manufacture. Therefore, they don’t usually cost as much to buy as zinc galvanized springs. Zinc springs cost a little more to make and aren’t as available to buy.
This is a quick look at the difference between oil tempered and zinc galvanized springs. If you’re ready to replace your springs, call your local garage door experts and they’ll answer any questions for you.
