Customize your own perfect pot for indoor & outdoor use


Looking for the perfect pots? Here is your answer. Now you can design your own modern plant pot by using maintenance-free Corten or design own lacquered planters. Even choose type of steel and thickness for your modern indoor & outdoor planters. Determine the height, width and length yourself (up to 2 meters). Choose between 3 or 4 mm thick sheet metal or 1.5 mm stainless steel. We fold top the edge of your perfect pots the same way as for our modern indoor planters in the Trendsetter series. If you are interested in an inner pot, we offer one in stainless steel with a self-watering part. Our outer planter is designed to fit insulation between the outer and inner planter (30 or 50 mm). We also offer a simple decorative frame to hide and protect the insulation.   If you add wheels, we make sure that the Corten planter has holes to easily mount these. If you need planters that are over 3 meters long, we offer a modular variant, with or without insulation, which you can adjust to any size.

Tip! If you are interested in building a fountain like the one on the image, the modern plant pot should be at least 30 cm deep so that there is always water for the pump. It can’t go dry. We suggest these pumps. You need one pump per bubble place.

Note that our largest Corten planters are delivered with standard steel finnish, which rusts naturally when used outdoors. If you want to speed up the process, you can spray salt water on your modern plant pot. Then it takes about a week to get a nice rusty surface (we describe how here). If you don’t want rusty modern indoor planters, we can paint your modern plant pot in any color. We offer RAL Classic as a standard choice, i.e. the codes that contain RAL + four digits. If your flower box is going to be outdoors, we use a primer to make it last. Hence, there is a price difference between the indoor and outdoor varnished version.

Choice of steel for modern plant pot

We recommend 4 mm thick steel for your modern plant pot so that they last many years. However, it is not uncommon to manufacture them in 3 mm. Corten itself is a durable steel where the rust that forms during outdoor use protects your planter box against further corrosion. However, it does not stop completely. If you choose to paint steel, the rationale about strong Corten steel to create long-term durability disappears. There we prefer to use galvanized steel, which is heat-treated so that the paint adheres. Despite that, we offer 3 or 4 mm steel as it is a matter of taste if you like thin or slightly stronger steel purely in terms of appearance. We also offer modern plant pot in acid resistant stainless steel. This steel is almost 5 times more expensive. From this, we have chosen 1.5 mm as standard for these pots. These pots are welded to a box and do not have a folded edge on the top. Note that if you want painted planters, it will take about two extra weeks.

Galvad plåt består av stål som belagts med ett tunt lager av zink genom att tillföra elstötar för att få zink att fästa på stålets yta. Denna yta skyddar mot rost. Däremot gör denna yta att det blir något svårare att få färg att fästa. För att få färgen att fästa värmebehandlar man slutprodukten innan lackering.

Rostfritt stål innehåller järn som blandats med minst 10,5% krom. Det finns 5 olika varianter av rostfritt stål där mängden krom är avgörande för vilken sorts rostfritt stål man avser. Beroende på vilka egenskaper som eftersträvas tillförs även andra ämnen utöver krom så som nickel. Detta för att minska risken för rost och tillföra andra egenskaper för att förbättra stålet användningsområde i något avseende.

Corten är en stålblandning som innehåller koppar, krom, mangan och nickel. Denna blandning förhindrar att stål fräts sönder vid utomhusbruk. Detta då det ytskikt av rost som bildas vid växlande väderförhållande blir självskyddande för stålet. Rostprocessen avtar i styrka när det har fått en snygg rostig yta som förhindrar att stålet fräts sönder.


Galvanized steel consists of steel that has been coated with a thin layer of zinc by applying electric shocks to cause zinc to adhere to the surface of the steel. This surface protects against rust. However, this surface makes it somewhat more difficult to get paint to stick. In order for the paint to stick, the final product is heat-treated before painting.

Stainless steel contains iron mixed with at least 10.5% chromium. There are 5 different variants of stainless steel where the amount of chromium is decisive for which kind of stainless steel being referred to. Depending on the desired properties, other substances are also added in addition to chromium such as nickel. This is to reduce the risk of rust and add other properties to improve the steel’s area of use in some respect.

Corten is a steel mixture containing copper, chromium, manganese and nickel. This mixture prevents steel from corroding when used outdoors. This since the surface layer of rust that forms during changing weather conditions becomes self-protective for the steel. The rusting process decreases in strength when it has acquired a nice rusty surface that prevents the steel from corroding.
