The Stratum planter is one of four planter designs from our all metal, modular planter products. It is a flexible, modular, aluminium planter design, available in a range of plan sizes and heights. The planter modules are available as a 4-sided, free standing planter, a 3-sided end module, 2-sided intermediate and corner modules and a single-sided module. This combination of units lets you create large or long linear planters, as well as shaped planters and stand alone units.
