Why we need weight bars on Roller door weight bars are very important components for ensuring the safe, smooth, and reliable operation of your door system. They primarily serve to add necessary mass to the bottom of the door, which is particularly crucial for doors with automatic openers and in areas prone to wind.
Key Importance Factors
Proper Closure and Operation: For doors with motors (especially narrow, chain-driven models), weight bars help the door feed down smoothly in the guide tracks and ensure it closes completely. Without sufficient weight, the door may bunch up at the top or fail to close properly.
Wind Resistance and Stability: The added weight at the bottom of the door, often combined with horizontal wind struts or reinforcement bars on the panels, helps the entire structure resist wind pressure, preventing rattling, flexing, or being blown in during strong gusts or hurricanes.
Reduced Motor Strain: The springs in a garage door system are designed to counterbalance a specific weight. The door opener motor works with the springs to facilitate movement, not lift the entire weight itself. A properly weighted and balanced door reduces strain on the opener, prolonging the motor's life and preventing premature failure.
Safety: An unbalanced or poorly operating door poses safety hazards. If components are overstrained due to incorrect weight distribution, parts like springs or cables can snap, leading to the door falling unexpectedly and causing serious injury or property damage.
System Longevity: By ensuring the door operates within its designed parameters, weight bars minimize excessive wear and tear on other mechanical components like rollers, tracks, and hinges, reducing overall maintenance and repair costs.
