Our Roll Up Shutter Door Torsion Spring, tailored for the Canadian and American markets, is crafted with meticulous attention to detail. We start with top - grade alloy steel that has been carefully selected for its high tensile strength and excellent resistance to corrosion, which is crucial considering the diverse climates across Canada and the USA.
The manufacturing process employs advanced CNC coiling machines to precisely wind the springs, achieving a uniform coil diameter and pitch. This precision not only optimizes the spring's force output but also ensures consistent performance over its lifespan. After coiling, the springs undergo a multi - step heat - treatment process. First, they are heated to a specific temperature to relieve internal stresses, followed by quenching and tempering to enhance their hardness and toughness. This results in a torsion spring that can withstand the rigors of continuous use in roll - up shutter door applications.
