Operations and Maintenance


Urban Pot planters are manufactured using 3003-H14 Aluminum, or 5052-H32, depending on application. These are the most widely used aluminum materials and are ideal for planters due the light weight combined with excellent strength and corrosion resistance. The aluminum we use contains a high percentage of recycled metal and in turn can be fully recycled in the future.

All Urban Pot planters are extremely durable and will be able to provide decades of sustained usage without mechanical issues. The planters are powder coated using industry standard exterior grade quality powders that are uv resistant. In addition to providing colour for the planter exterior the planters are also fully powder coated on the inside which will protect the aluminum from highly corrosive fertilizers if these are used.

As an option, we offer inside lining made of cellular foam, extruded polystyrene thermal insulation panels & bottom drainage layer composed of a post-industrial recycled polypropylene drainage core of fused, entangled filaments onto which a fabric made of a non-woven needle-punched polypropylene fiber is factory-laminated.



Urban Pot planters require no maintenance from a material or mechanical standpoint, but in terms of daily use we recommend the following ‘best practice’ guidelines:

Aluminum is rust resistant and extremely durable. Salt and fertilizer are both highly corrosive and will corrode most metals including aluminum and stainless steel. The powder coating provides a protective layer so as much as possible avoid chipping the paint. If the coating does chip rest assured any corrosion will not creep under the paint as happens with steel.

Cold weather will not harm aluminum planters but when water freezes it expand by approximately 10%. Freezing water will break a mountain and your planter if is fill with water before or during the winter. The best way to prevent this from happening is to :

  • Ensure that the planter is filled with earth up to about 1” of the top before winter sets in.

  • Always use topsoil in the planters as it retains less moisture than potting soil.

  • Sometimes it is possible to cover the planters during the winter months. It probably won’t be necessary, but it can’t hurt.
