Steel Cube Planter

These products are still available to ship

If you are after a contemporary look the clean lines and flawless finish of powder-coated steel planters tick the right boxes.  Using our years of experience in producing top-end steel planters for the trade, we have developed a range of standard designs in large sizes, offering great value for money and designed to suit both private and commercial requirements. This cube planter is available in four sizes, from 50cm which is suitable for - for example - topiary by a front door, to a 100cm cube which can be used as a tree planter.

We manufacture in 2mm steel, which gives rigid, no-flex planter walls. All corners and edges are fully welded, i.e. smoothed off for a perfect finish, with no folded seams or rivets. The planters are raised on small feet to aid drainage. The powder coating is applied inside and out for ultimate lifespan, and is baked at 200℃ to create a durable and hard-wearing finish.  

Colour choice
Our powder-coat colours have a semi-matte appearance, with a very subtle sheen to the colour.  The standard range of colours shown below are popular tried-and-tested variations on neutral shades, including three with a metallic  hint.  There's also the option of a custom colour from the RAL colour series.  Colour sample panels can be ordered here.    


Or select a RAL colour code (+£75.00)

Planter care
Planters can be washed using water with a mild detergent. The paint finish does not damage easily but avoid using abrasive cloths or cleaners. Should the surface get badly damaged (scraped through to the bare metal) then we can provide a touch-up paint kit, which should be applied to prevent corrosion.  

Coastal Locations
We do not recommend powder-coated steel planters in general for coastal locations as heavily salt-laden winds can shorten their lifespan. It is possible to powder-coat stainless steel or marine grade stainless steel planters which will withstand these conditions, and we can offer this as a bespoke service.
