Flower containers – Among the many prefabricated containers for plants and shrubs offered in our retail chains, it is worth recommending large containers of various shapes made of mesh concrete.. Despite their large dimensions, they have a relatively low weight, because they are characterized by thin walls and bottom. And thanks to the reinforcement with a thin mesh, concretes are very durable and resistant to changing weather conditions, even extreme ones. We can buy rectangular boxes, a square or hexagon of different heights.
