Planters are shaped from metal by skilled craftsmen utilizing precise folding of the metal to create a planter that uses no welding during the manufacturing process, and assembles into a rectangular shape from five panels. The planter panels interlock to form an incredibly solid plant container that can accommodate large plants. The planter sits in a steel caster (wheel) frame. All four casters swivel and have built-in brakes. This planter is simple, modern and minimalistic. Corten Steel planters do not ship pre-weathered and will arrive with the bare steel finish which will have to weather over time. During the weathering process staining to adjacent material may occur.
