Planters up to more than 3,0 m (≈ 118.11 in) long and more than 2,0 m(≈ 78.74 in) wide are delivered in one piece. Bigger planters are easily but solidly bolted together on site – using a copyrighted Gartenmetall® bolting system. These bolts cannot be seen from outside. Because the sharp edges at the top are removed the single elements have a very high stability in spite of the relatively thin sheet thickness. If this stability is not enough for high or very long planters, then cross pieces and longitudinal braces are integrated, which cannot be seen afterwards because of the filling.
The installation effort on site is minimal. Because of the integrated installation brackets the elements are perfectly adjusted. This patent was developed by Gartenmetall® and has become a new standard on the market.
