Miths to dispel: When it hails, should plates open or not? If they opened, you’d get hit by hail!



When it hails, should plates open or not? If they opened, you’d get hit by hail!


Anti-hail systems are a fundamental tool for farmers because they protect the cultivated fruit, guaranteeing a certain income thanks to the harvesting of healthy, large, quality fruits.

Such systems are essential because it’s now clear to everyone that changing weather conditions no longer allow keeping an orchard unprotected. Indeed, it may even be necessary to upgrade systems where the weather is becoming increasingly violent.




Precisely for this reason and due to exceptional weather events, some people are wondering if it’s right for the nets’ fastening plates to “release” after a certain weight to let the accumulated hail drop to the ground, avoiding overloading the structure.



Indeed, in some cases and in areas that are particularly at risk (usually in the mountains) there’s a chance that snow can surprise farmers who have yet to harvest their fruit and therefore still have their nets open.



Unfortunately, we know the end result very well and it’s disastrous, but we also know that anti-hail structures were NOT designed to withstand the weight of snow.

If the plates REALLY came off when the load on the nets exceeded a certain weight, we would have a rather unique situation.

If the plates released in the middle of a hailstorm then the netting would fall onto the existing plants, but due to its limited width it would cover only a part of them, inevitably leaving at least half of the fruit unprotected. The result would be fruit damaged by hail underneath the structure!



It seems clear that the system must be designed to withstand the greatest possible loads and winds that accompany these atmospheric events, avoiding as much as possible that the plates release simply to avoid overloading the structure.

If well designed and made to perfection with the best possible materials, the structure can withstand considerable stresses, including winds blowing up to 100 km/h and snow loads of over 60,000 kg/ha.
