ROC Coil Spring

Supplementary Information.

• Produced in Lesjofors, Sweden using cold coiling technology, ROC springs undergo a comprehensive manufacturing process for peak performance and longevity.
• Shot peening enhances fatigue strength and prevents premature breakage in all ROC springs by introducing positive residual stress.
• ROC springs are corrosion-resistant with Zinc Phosphate providing sacrificial protection, and epoxy powder resin paint adds further corrosion safeguards.
• ROC maintains stringent inspection and testing procedures to ensure the highest quality standards in their springs, which are engineered for quality, durability, and corrosion resistance.
