FEATURES

The Cor-Ten (English CORrosion + resistance TENsile strength) was patented in 1933 by the American United States Steel Corporation, as high-strength low-alloy steel and passivating,
defined 'patinable'.

Patinable in steel (weathering steel), the rust is "desired" because it is a protective layer of oxide with a strong grip that has excellent resistance to atmospheric corrosion. This film is characterized by a porous outer layer and a thin inner layer of amorphous and waterproof rich in copper, chromium and phosphorus, which confers resistance to corrosion.

Determining factors for the correct  flowering of patina are:
photo catalytic action of sunlight;
alternating cycles of wet-dry;

The Cor-Ten steel material is a paradox, but that is what makes it particularly interesting. In fact, the main peculiarity Steel Cor-Ten is to protect itself by electrochemical corrosion, through the formation of this passivating surface patina compact that prevents progressive spread of corrosion because the natural oxidation stops with time. This film varies in hue with the passage of time, usually has a brown color.

If the surface patina is dented or scratched, the steel is oxidized again to build a new protection that lasts the test of time. This phenomenon of regeneration can be repeated several times, thus maintaining continuous protection. It is therefore a material that "lives" and protects itself.

The color varies in the course of the oxidation process, starting from an orange to a coloring
stabilization of the seals reddish-brown patina that, under normal environmental conditions, occurs in 18-36 months with a decrease in the thickness of only 0.05 mm.

The hue that has its origin in the oxidized surface is hot and intense and offers many aesthetic solutions in relation to the unusual "elegance of rust" which emphasizes the feeling of living on the ravages of time, as evidenced by the extensive use of buildings and monumental sculptures outdoors.

ADVANTAGES

There are clear technical and economic advantages of the tenants that can be achieved with the use of Cor-Ten. In fact, by adopting this type of steel instead of carbon steels, it is possible to achieve considerable reduction in thickness and weight which result in a considerable saving of money!

In addition, the high resistance offered by the Cor-Ten to atmospheric corrosion, allows the use of the product as "naked." The resistance to the attack of atmospheric agents is five to eight times higher than that of a common carbon steel and for its pleasant appearance, is particularly suitable for agricultural applications.

THE POLE IN CORTEN:

1) It has a very long life
2) Avoid the phenomenon of "reflection of the sun" typical of galvanized poles
3) It's ideal for the automated collection
