High Strength Tighten Lubricate Garage Door Torsion Spring Right / Left Direction

Specifications:

Description:       

1, high carbon steel 82B is used to make garage door torsion spring in XULONG SPRING,this kind of material own higher strength which can reach 1800Mpa,high strength mean guarantee better mechanical and guarantee high quality of the garage torsion spring.

2, process of heat treatment is a must producing process for garage door torsion spring, the heat treatment here we call annealing and its main aim is to reduce the internal stresses created during rolling process.

3, the length,exactly speaking,the number of coils is one of the main factors to determine the spring rate of garage door torsion spring,or the torque of torsion spring in other words,so we add a process to adjust number of coils specially with cutting by punch and make sure each spring have the same coils asdrawings.

4. for package,five or six pieces of garage door springs are packed in a plastic bag,then put them into a wood case,and container final.torsion springs will reach your port perfectly.

Applications:

Garage door torsion spring counter balance the weight of the door to make it easy to open and close,typically two torsion spring balance each door,the torsion spring secure to the outer drum with a bolt,the other end secure to door bracket to the outside of door,the axle passes through bracket,also through the middle of garage door torsion spring.

 How to order your garage door springs
