Even though Corten is only 14″ thick, it is extremely robust and provides high structural strength. As a result, carbon steel is becoming very popular as a lighter weight and lower maintenance alternative to other types of steel. The Manufacturers’ Standard Gauge for Sheet Steel assumes an average density of 41.82 lbs for carbon steel.

What is the weight of Corten steel?
Steel alloys like corten are designed to develop a protective layer of rust over time when exposed to the elements, which gives them their characteristic rusty appearance.
It depends on many factors, including the thickness of the material, the size and shape of the piece, and the composition of the alloy.
Corten steel has an average density of 7.85 grams per cubic centimeter (0.284 pounds per square inch), which is slightly higher than regular carbon steel. A Corten steel piece’s weight can be calculated by multiplying its volume (length x width x thickness) by its density.
As an example, a Corten steel plate with dimensions of 2 meters x 1 meters x 6 mm would have a volume of 0.012 cubic meters (2m x 1m x 0.006m), and a weight of approximately 94.2 kg (0.012 x 7.85 x 1000).
What is the advantage of Corten steel?
There are several advantages to using corten steel, including its unique appearance, durability, and corrosion resistance. These are some of the advantages of Corten steel when it comes to weight:
- In terms of strength-to-weight ratio, Corten steel has a high value, which means it is relatively strong for its weight. Construction and structural applications where strength and weight are critical make it an ideal material.
- Over its lifespan, Corten steel requires little to no maintenance due to its corrosion resistance. Since it can withstand harsh weather conditions and exposure to the elements without deteriorating, it makes an attractive choice for outdoor structures and applications.
- Corten steel has a longer lifespan than many other materials due to its durability and resistance to corrosion. As a result, replacement and maintenance costs can be reduced over time.
Corten steel’s weight is only one factor to consider when evaluating its advantages. A variety of applications, including architecture, construction, and landscaping, are made possible by its unique appearance, durability, and corrosion resistance.
Corten steel disadvantages: how heavy is it?
Corten steel has several advantages, but there are also some potential disadvantages to consider, including:
- Because of its unique properties and specialized manufacturing process, corten steel can be more expensive than traditional carbon steel or other materials.
- If water runoff is not properly managed, Corten steel can stain surrounding materials such as concrete or stone due to its rusted appearance.
- It may be more difficult to source corten steel in some regions or for certain applications because it is not as widely available as some other materials.
- Energy-intensive manufacturing processes used to produce Corten steel can contribute to environmental pollution.
- While Corten steel generally requires little maintenance, if it is scratched or damaged, the protective rust layer may be compromised, which may result in faster corrosion.
Before making a decision, make sure you carefully evaluate Corten steel’s advantages and disadvantages within the context of your specific application and project requirements.
What is the weight of the Corten steel test certificate?
Test certificates for Corten steel provide information about the quality and characteristics of the steel. Typically, these certificates include information such as the chemical composition of the steel, its mechanical properties, and any testing or inspection that has been performed.
Corten steel test certificates are typically just a few pages long, so their weight is negligible. Nevertheless, the information contained in the certificate can be useful in ensuring that the Corten steel product is in compliance with the specifications and standards required.
Test certificates for corten steel are usually issued by the manufacturer or supplier of the steel product and may be required by customers or regulatory bodies. Ensure that the necessary documentation is provided by the steel product’s manufacturer or supplier if you require a Corten steel test certificate.
It is a high-strength, low-alloy structural steel with improved atmospheric corrosion resistance, suitable for angles, channels, beams, as well as steel plates and bars.
In the case of a 3mm corten sheet, the density is 7.85 g/cm3, which translates into 23.55 kg per square meter of material.
This steel is a low-alloy, high-strength structural steel that is highly corrosion resistant with improved atmospheric corrosion resistance, suitable for structural steel shapes such as angles, channels, beams, as well as steel bars and plates.
When exposed to the elements, Corten Steel Sheet forms a protective layer of rust due to its chemical composition.
As a result of its corrosion resistance, ASTM A588 weathering steel sheet is commonly used in welded bridges and other structures.
