Numerous interior designers and planners often decide to use the Corten in modern spaces,  thanks to its specific properties. Corten is also non-toxic, environmentally friendly material, which nowadays is gaining in importance every year.

In the past, Corten was primarily seen as a durable and corrosion-resistant raw material used for manufacturing in heavy industry. Currently, it is being used in building facades or as an addition to interior design and gardens. Corten perfectly emphasizes aesthetic values of modern shape when it comes to industrial, public and private construction.

Reasons to use Corten weathering steel.

Corten steel has a broad spectrum of valuable properties, of which first significant is increased resistance to extreme weather conditions. Corten under the influence of rainfall and air produces on its surface a rust-like coating. However, this coating is much different from the standard corrosion, as in this case, it is not damaging to the material, but instead serves as a protective layer created by several chemical elements such as nickel, phosphorus, chromium and copper.  Protective outside layer made of those elements doesn’t progress deeper into the material, which means that Corten has little to none requirements regarding impregnation or special care. It also does not generate additional costs in the form of the need for regular painting or renovation.

Products made of Corten steel do not require surface treatment. It is an undoubted advantage because the elements made of it usually take on a red-brown colour over time. It makes the appearance of each product unquestionably unique.

Thanks to the industrial character, Corten is increasingly used not only in industry but also in modern architecture and art. The innovative nature of the metal blends in perfectly with the greenery in the garden. Astounding designs of sculptures, benches, water elements, planters, furnaces and wall panels are created from Corten steel.

Corten is currently a very fashionable material used by world-class designers. They appreciate the warmth of colour, simplicity in processing, ease of maintenance and, above all, high durability. Also, the small thickness of the corten plate allows you to create openwork structures for the garden, such as pergolas, lighting elements, gazebos and partitions. Lamps made of Corten steel are also produced, which generate phenomenal visual effects both during the day and at night.’
