In recent years, landscape designers have been attracted to the charm of weathering steel. The clean lines it creates in the yard and its beautiful, rustic decor are a major draw, and for good reason. But if you're not prepared to let a professional landscaper install custom work for you, then consider looking for some weathering steel planters.

Used in commercial and residential Settings, these steel plantings provide a durable, simple alternative to wooden plantings. Compare their cost to their life span and there is no doubt that they are cheaper as a long-term solution. Modern, smooth lines create visual appeal, and its natural rust-colored surfaces can be used for contemporary architecture and more nature applications. Best of all, corten steel planting has a simple assembly process that makes it possible to achieve the ideal garden space you are looking for.

Let's take a look at what weathering steel really is and how it is used to make weather-resistant flower POTS. We will explore some of the changes in metal and how it is produced, give you insights into what you should buy, and make some good suggestions for choosing when to incorporate Corten into your garden space!


What is weathering steel?


Weathering steel is a kind of weathering steel. The steel is made from a group of steel alloys that corrode and produce a rusty green over time. This rust acts as a protective coating, so no paint is needed. Corten steel has been used in the United States since 1933, when the United States Steel Corporation (USSC, sometimes referred to as U.S. Steel) implemented its use in the shipping industry. In 1936, the USSC developed railroad cars made of the same metal. Today, weathering steel is used to store containers because of its ability to maintain structural integrity over time.

Weathering steel became popular in architecture, infrastructure and modern sculpture art around the world in the 1960s. In Australia, the metal is most prominently used in construction. There, metals are incorporated into the commercial landscape of planter boxes and incubation beds, as well as providing the building with a unique oxidized look. Due to its rustic aesthetic appeal, weathering steel is now widely used in both commercial and domestic landscapes.

Most people think rust is bad, but for Redcor Weathering steel, it's a good sign. The steel is exposed to alternating wet and dry conditions, creating a layer of patina that forms a protective layer over the metal. With the passage of time, the change of the luster of steel is a noteworthy phenomenon. It starts out as a bright orange, then turns dark brown to blend in with its natural surroundings. In the later stages, it becomes almost a purple hue. This color change occurs under optimal wet/dry conditions. Those obtained by planting boxes made of Redcor can weathered steel themselves during alternate wet and dry periods less visibly.

There is a slight change between Corten Steel and Redcor. Most Corten products are hot-rolled molded, but Redcor steel is cold-rolled, making it more uniform and reliable between products. The two uses for each type are also different. Weathering steel is used in the railway and shipping industries. Redcor is most commonly used by architects and landscape designers to produce planter boxes, cultivation beds, or other garden decorations. The high phosphorus content of Redcor makes it ideal as it leads to higher corrosion resistance over the life of the metal. Once it forms an oxide layer, the metal beneath it no longer deteriorates, and it can protect itself.

Safety of weathering steel


Gardeners may want to know about weather-resistant steel flower POTS and whether they are safe for growing food and ecosystems. These concerns can be removed! The corten steel seed box does not filter any hazardous material into the ground, just a little iron. Adding more iron to the pot or culture bed can boost plant chlorophyll development when high acidity does not destroy the protective coating prematurely.

The same applies to the ecosystem surrounding the Corten Plantation. There's not enough corrosion happening to worry about contamination. There is one thing to consider, however, and that is that the weathering steel planter box may stain the hard landscape. Gardeners should lay down tarps, MATS, or other materials to prevent unnecessary staining of the concrete or deck. Combine it with gravel to highlight the tone of a beautiful flowerpot box!

It takes a while for your bed to grow natural, protective patina. To accelerate its development on a Corten steel planter box, we recommend filling the spray bottle with 2 ounces of vinegar, half a teaspoon of salt and 16 ounces of hydrogen peroxide. Shake the bottle vigorously to combine the ingredients. Wear gloves and goggles and spray the entire surface of the pot box. If the spray texture on the pot needs to be smooth, wipe it down with a towel. This accelerates the development of verdigris and forms a protective coating on the oxidized metal. Repeat this process over time, allowing it to dry between treatments until your metal pot achieves the look you want. It's easy!

Once the oxide patina is fully developed to your liking, you have a nice oxide coating that will stabilize your pot. You can even lock in the color with a coat of polyurethane paint after the cladding is fully formed. Before painting the entire metal flowerpot box, make sure the weatherproof steel flowerpot box is the color you want and test a small area, as the polyurethane coating may make it look darker. You don't have to paint POTS if you don't want to; With or without the extra coating, it will make a visually good planter!
