Galvanized steel structure Advantages over the competition: Our greenhouse has many more steel struts than conventional models (marked in red). Our greenhouse in the green vegetable garden has a galvanized steel frame and is equipped with 2 storm poles for year -round durability. Important information: Placing it on the ground is not enough. Our greenhouse has better wind resistance thanks to the tarpaulin to be buried, but does not mean that the greenhouse is resistant to medium and strong winds. It is therefore strongly recommended to remove the tarpaulin in windy conditions. Otherwise, it is also advisable to bury the metal structure and the lower edge of the foil in the ground or to reinforce the ground support.
