IOTA custom-manufactures zinc planters in any shape or size, from simple geometric shapes to complex architectural designs.

Manufacture

Smaller planters can be manufactured from a single skin of zinc sheet. However, as Zinc is a relatively soft metal, larger planters are manufactured from 1.2mm zinc which is clad onto 2.0 or 3.0mm zintec steel. The resulting double-skin planters deliver the unique aesthetic of zinc, whilst relying on the superior strength and stiffness of steel for the planters’ technical performance. 

Material

Zinc is one of the longest-lasting of planter materials, as the surface naturally oxidises with a protective layer which requires no maintenance.

Finish

Zinc planters are generally supplied with either a dull ‘knocked-back’ finish, or with a pre-patinated finish; the intention being that the planters will then age naturally outdoors. The images show pre-patinated zinc planters at a relatively early stage of natural ageing; with a general background patina resembling old lead, with natural and characteristic zinc oxide highlights starting to come through. Over time, the planters will become generally lighter, with increasing levels of tonal variation and highlights.
