Good evening,

the structure for our greenhouse has arrived. While the previous owner
claims that the arcs just need to be set on flat ground, I have a doubt,
that the greenhouse can withstand the winds in this way.

The arcs end in steel-boards with a “Z-profile”, like in this drawing (I
hope you use a mono-spaced font for the news):

| top
right _________ left |
/________/ | | |
| | | | |
| ( ) | | | |
|________| | \__|_|__
/________/ | \
| bottom

Does someone know this kind of greenhouse structure?

The profile has certainly a meaning and my wife and me consider sinking
the boards low enough into the ground to put weight on them; either
stones or cement.

The whole greenhouse will be 6x20m (120m²) with vertical “walls” up to
about 1.9m, which means a considerable weight, but also a considerable
surface. Even if I choose an intelligent orientation and a good
compromise between insolation and wind resistance, some additional
anchoring should be needed, I guess.

TIA,

Michael
