Let’s start with the current record holder. Our tallest AB Fence system built is located in South Hackensack, New Jersey and reaches a maximum height of 30 ft (9.0 m). For a complete write up you can check out the case study, Tallest Sound Barrier. I would doubt we will see too many projects that will require a taller fence than that.
Most of our fence projects range from 6 ft (1.9 m) to 12 ft (2.8 m). However, instead of focusing on the maximum height, let’s talk about what factors will influence the height.
- Wind Pressure – based on climate information for your area and average wind speed is known.
- Exposure to the Wind – fences that are constructed on shorelines and in open areas will be unprotected to the wind more than fences that are located around buildings.
- Post spacing – this all comes down to the size of the panel area and how much pressure is being supported by the posts.
- Concrete Strength – there are limits to the strength of concrete and too much pressure could cause cracking and failure.
- Structural Steel Design – this includes the amount of steel located in the posts as well as the bond beams within the panel. The more bond beams used the stronger the panel becomes.
