No, the Modern Elite Planters are lightweight.
The benefit of aluminum is its high-strength to weight ratios. Most of the weight will actually come from the type of fill and type of plantings used. The material weights will change and will be based on the size of the planter and if additional reinforcing is required. Please contact us to receive the exact weight of the product you would like to purchase.
If weight is a concern, our recommendation is to focus on reducing the weight of fill material and plants inside the container. If you can reduce the planting depth to a minimum, you can then fill the void spaces with Styrofoam, non-biogradable packing peanuts, or our EZ Fill-ter bags. It is recommended to wrap the void fill in a landscape fabricate to create separation from the planting soil and to provide filtration.
We recommend contacting a structural engineer to verify that the deck can, in fact, hold the number of planters that you are ordering. However, in general, decks and rooftops are designed to carry 50 lbs./SF or more. For example, the 72" L x 20” W x 24” H aluminum planter only has a load of 6.9 lbs./SF so the majority of the weight comes from what used inside the planter.
