Corten Steel - CUADRA

CORTEN STEEL

The hallmark of true craftsmanship lies in the quality of its crafting techniques.

This is why Cuadra has chosen to use a completely natural oxidisation process.
No chemical products are used, just quality which responds to the rhythm of nature.


The Cuadra oxidisation process produces a material which, when ready for sale, has oxidisation equivalent to around 5 months of exposure to sun and rain. Through this process, the Corten becomes covered with an even, protective patina of oxides from its alloy elements, which prevents the spread of corrosion.

This protective coating, which is an attractive brown colour, will go through a variety of shades through the years, so that besides providing effective protection against the weather, it will also continue to make the product more beautiful.

Cuadra’s metalwork production includes different types of Corten, each distinguished by a particular finishing treatment.
Natural oxidised Corten

The Corten steel is subjected to the Cuadra natural oxidisation process.

FINISH: Natural Oxidised
USE: Outdoor
MAINTENANCE: None required
Oxidised with anti-leaching treatment

After the Cuadra oxidisation process, the Corten is coated with an anti-leaching patina which does not alter the surface of the material but prevents corrosion caused by atmospheric agents.

FINISH: Oxidised with anti-leaching treatment
USE: Outdoor
MAINTENANCE: None required
Oxidised and waxed

After the Cuadra oxidisation process, the Corten is covered with a stabilising surface layer of wax.

FINISH: Oxidised and waxed
USE: Indoor
MAINTENANCE: regular waxing
Oxidised with resin coating

After the Cuadra oxidisation process, the Corten is covered with a stabilising resin which prevents the rust from rubbing off and provides greater surface protection.

FINISH: Oxidised and resin coated
USE: Outdoor/Indoor
MAINTENANCE: occasional application of resin
