Corten steel

Corten steel or the Cor-TEN If we need to use the right term is a type of steel that rusts quickly in the surface, but has a slower penetration than, for example, soft steel. One can thus say that the rust layer prevents the material from rusting. CThus, orthe steel can last outdoors for decades - completely maintenance -free.

When we process the material at our factory, the material is similar to ordinary black steel. On delivery, the steel is still black, but after a few weeks of outdoor location - depending on the season - the rust layer will slowly emerge. If you are impatient, the process can be accelerated by once washing followed by salt water spray.

When placing on tiles or wood, the substrate must be protected for the first time from rust markings, as the rust in the rain will drip down the substrate. This subsides after a few months, but we always recommend paying attention.

When you receive your Corten plant box or high bed, it looks like first picture. This is what the steel looks like before it begins the rust process. 
The beautiful red color gradually changes with the weeks, months and years, and you can therefore experience your products change color.

High -beds, plant basins and outdoor fixtures in corten steel

Whether you plant in wood or steel beds makes no difference. The steel can give off a bit of rust at the edge of the bed, but not something that is dangerous for neither plants nor soil.

A walk in the world's largest cities and latest neighborhoods shows a great trend in the design of outdoor areas. Maintenance -free elements in raw steel look -corten steel. Where we have seen rust in the past as a problem and something to be hidden with paint, we now experience the red color as trendy, welcoming and warm. The red rust color in its look and experience is very similar to wood, but with better properties in durability and maintenance. Rusty iron look - corten steel - is the very hot material of the time. At Byjema we love the Corten look!
