Why Chose Corten Steel:
Corten steel is a type of steel that develops a protective layer of rust when exposed to atmospheric conditions. It means the life span of corten steel is 10 time longer than mild steel and 3-4 times longer than repainted steel.

Anti-corrosive
Corten steel has anti-corrosive properties that gives it an advantage over other steel. The naturally occurring rust that it develops helps to lengthen the lifecycle of its structure, which in turm keeps costs to a minimum.
In a word
No trouble, save time
Longer lifetime, save money

FAQ
Q: How long does it take for Corten steel to rust?
A: Naturally, the rust forms on Corten Steel planter over 3-12 months, depending on how often it is exposed to weather, climate, and other environmental factors.
Q: Are metal planters bad for plants?
A: Metal containers are highly effective at conducting both heat and cold, potentially leading to overheating or freezing of plant roots during severe weather conditions. Generally, the smaller the container the more vulnerable it is to extreme temperatures.
Q: Do corten steel planters stain?
A: It is true that weathered steel planters and other products will produce a rust-coloured run-off that can stain patios and surrounding areas. However, this is mainly an issue during the weathering process, which is when the corten steel achieves its beautiful, unique, and protective rust-like coating.
Q: Is corten steel just rusted steel?
A: Corten Steel (sometimes known as weathered steel) is a group of steel alloys that are often used in outdoor construction. Corten Steel was designed to eliminate the need for painting and if left outside, exposed to the elements, they will develop a rusted appearance in just a few months.
Q: Are metal planters too hot for plants?
A: Will a metal garden bed cause plants and soil to overheat? The answer is no. The temperature of the soil near the edges of the garden may rise slightly on a warm day but not enough to have any impact on your plants. If you properly water your garden bed plants, you should not have to worry about them drying up.
Q: Is Corten steel worth it?
A: The longevity and low maintenance nature of Corten Steel make it a highly cost-effective choice in the long run. Its durable nature means fewer replacements over time, resulting in cost savings. The absence of painting and ongoing maintenance costs also contribute to Corten's cost-effectiveness.
