The steel foundation made of galvanized and color-coated sheet steel simplifies the assembly of a greenhouse. It is always absolutely flat and right-angled, making it the ideal link between the greenhouse and the foundation. This ensures the long-term stable status of the greenhouse. In addition, the foundation frame increases the overall height of the greenhouse: plants and gardeners gain a little more space in the interior. The steel foundation frame comes with screws and foundation clamps for attachment to the greenhouse and the foundation.
