Why Roller Door Maintenance Is Essential
Regular maintenance is essential to keep your roller door operating smoothly, quietly, and reliably. Since every roller door faces different environmental and usage conditions, our professionals recommend checking its operation regularly and scheduling a service every 3–6 months, or at least once a year. Never attempt to adjust the door yourself — always rely on our trained Three Sinha technicians to protect the door’s quality and longevity. If you notice anything unusual, contact our Repair and Aftersales Department immediately.
