|Hardness Conversion Chart|
Roller shutters are widely used all over the world. One of the most important components of this roller shutter is the shutter spring, which is made from our Hardened & Tempered Steel strips. The shutter spring steel strips produced by Hard Strips (India) have uniform material hardness and tight geometric tolerances, which helps to maintain constant torque and this along with the clean round edges ensures the smooth functioning of the roller shutter. This increases the life of the roller shutters.
