Heavy gates—particularly wrought iron and solid wood—need gate operators rated for their weight. Choosing the wrong operator leads to slow operation, strain, and premature failure.
Understanding Gate Weight
Typical Gate Weights
- Aluminum: 3-5 lbs per square foot
- Steel tube: 5-8 lbs per square foot
- Wrought iron: 8-15 lbs per square foot
- Solid wood: 10-20 lbs per square foot
Calculating Your Gate Weight
A 12-foot wide by 6-foot tall wrought iron gate could weigh 600-1000+ pounds depending on design density.
Operator Capacity Guidelines
Size Up Your Operator
Choose an operator rated for at least 25% more than your gate's actual weight. This provides:
- Adequate power for smooth operation
- Reserve capacity for wind load
- Longer operator lifespan
- Better performance as components age

Special Considerations
Wind Load
Solid gates catch wind like sails. Factor in wind load when sizing operators, especially for hillside properties.
Cycle Frequency
Heavy gates that operate frequently need operators rated for continuous duty.
Power Supply
Heavy-duty operators may require 220V power rather than standard 110V.
