CORTEN STEEL

Corten sheet and corten tube

HISTORY

History of corten steel

In the history of corten steel we have data from 1822 which states that adding copper to normal steel the resistance to corrosión was better, but it was really since the 20th century when this steel started to be investigated. In 1933, Kendal and Henderson from USS Stell started comercializing this steel under the name of Cor-ten, adding 0,03% of Copper to the chemical composition.

In later years the number of tests increased until incorporating Si (silicon), P (phosphorus) and Cr (chromium) to the formula and two versions of the corten steel were developed: One with nickel called Corten A and without nickel called corten B. In EEUU test were made about the oxidation in different atmospheres. The ASTM comittee exposed different steels with copper content adn they saw that the self-skating steel could be used wihtout paint and galvanization for bridge works where a durable steel with at least 100 years of durability was needed.

CHARACTERISTICS

The main characteristics of the corten steel are:
The corrosion speed is much Slower than the normal steel
Self-protector steel, protects the base steel and do not lose the mechanics characteristics
Weathering similar to copper which ennobles the surface
Atmospheric aging steels
Soft steel with les than 0,2% of C and 5-8% of additional alloying

METALCORTEN ROUGHING ACCESSORY

Special roughing discs for Corten Steel

ELECTRODES FOR CORTEN STEEL

Our R&D department has developed special discs which composition is a polyamide mixture for the removal of calamine from the steel. Our discs completely clean the calamine of black carbon steel, preserving 100% of the base steel. This way, the mechanical characteristics of Corten steel prevail intact and with the perfect finish for uniform oxidation.

For good handling by professionals, we manufacture it in 125mm diameter. In this way the weight of the radial machine does not affect working time.

To purchase, contact our commercial department.

ACCESORIES AND RUST ACTIVATORS

Rust activator products and specifications

ELECTRODES FOR CORTEN STEEL

The special electrodes for corten is an electrode with a humidity-resistant coating, LMA alloyed with Ni and Cu, which contributes to a steel with a really good resistance to the corrosion by seawater and combustion  gases. It is appropiate for the welding of weather-resistant steels (COR-TEN) and for shipbuilding. This electrode can be used for all types of joints and welding positions.

METALCORTEN RUST ACTIVATOR

CHARACTERISTICS
METALCORTEN RUST ACTIVATOR is an oxidizing solution of water-soluble mineral salts to accelerate the rust process on iron and steel-made surfaces such as the corten steel.

SURFACE PREPARATION
The surface must be without calamine. Hot-rolled iron, black iron and cast iron must be blasted to remove the calamine present on the surface. If the surface has grease, it must be degreased.

APLICATION
Let the product act and repeat the aplication. Although the rust starts instantly, we recommend to let the product act during at least 3 days.

METALCORTEN PROTECTOR

It is a trasnparent sealer that proctects the steel and surfaces from the paints and effect range. Effect sealant forms a film on high acidity surfaces, prevents subsequent oxidation and prevents the color from yellowing. Chemically protects and minimizes subsequent oxidation, creating a self-reticular barrier to resist weathering. It does not require dilution with water when applied directly to metals. When applied over iron, copper or bronze paints, dilutes only the 1st layer in equal parts with mineral water. It does not require the subsequent application of any finished varnish. Note: The Effect Sealant product is sensitive to moisture during the drying process. When working outdoors, do not apply the product if there is a risk of rain during the 3 days following application.

FAQ

FREQUENT QUESTIONS

¿What is the corten steel?

‘COR-TEN A’ type steel has a high content of copper, chromium and nickel. This chemical composition makes it possible to create a oxide layer . Therefore, the corrosion of steel is stopped thanks to the self-protective action of the rust. Since its surface oxidation can be largely stopped with stop baths.

What standard measurements does the industry offer?

Corten steel is supplied in sheets with a width of 1000, 1250 and 1500 mm. The lengths can be 2000, 3000 and 6000 mm. Standard thicknesses are the following: 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20, 22, 24, 25, 30, 35, 40, 45, 50 , 60, 70, 80 and 90 mm. It is possible to obtain special measurements upon request, such as square or rectangular tube, round tube, etc.

What is the utility?

The resistance of Corten steel to the corrosion gives to this material special characteristics. It can be left outdoors without requiring any maintenance, which is why it has been used in the creation of architectural and sculptural objects, using Corten steel sheets, as well as for furniture design, decoration, gardening…, for example Corten steel planters. , wall covers, gutters, gutters, etc.

Is it necessary to protect Corten steel?

In the surface oxidation of Corten steel, an oxide film impermeable to water and water vapor is formed, which prevents oxidation from continuing, so it is not necessary to apply any other type of protection to the steel such as galvanic protection or painting.
