How to Extend Roll Up Door Springs Service Life?

During make a Roll Up Door, each spring should be coated with a generous amount of grease that penetrates the innermost pores of the spring with additives, displacing moisture and preventing the formation of rust and corrosion. In addition, this process relieves the friction created between spring coils, thereby providing a smoother door operation. Finally, the spring and axle assembly is enclosed in a tube to protect them from the elements encountered throughout the life of the door.
