Here are some beautiful rolling planter boxes we made for The Rockaway Hotel. They had a PVC inner box with a solid sheet of HDPE we made to look like planks on the outside. The HDPE will take the occasional bump, kick, etc. being in a commercial environment. They have a aluminum frame underneath and stainless steel casters. They will use them to divide areas and also just to add color and texture to the environment.
Being that they are very heavy they are also great for rooftops. Rooftop gardens are very popular in New York City, Queens, Brooklyn, and New Jersey. We can also make these planter boxes stationary and custom sizes. They can be made using HDPE which comes in multiple colors and also Versatex pvc for more of a traditional planter box look.
