Corten steel usually costs three times as much as mild steel. However, the cost will also depend on various factors such as the amount, the length and the weight of the steel you wish to purchase.Corten is significantly more expensive than other common grades of steel.
Corten steel planters are easily 50%-100% more expensive than a similar sized planter made of another long-lasting material. Stainless steel is more expensive than other steel types.
Corten steel is twice as expensive as regular steel, so it should not be used. Corten steel has the main advantage of being cheaper than galvanised steel. If the members are too big to be galvanised, such as bridges, the cost curve might be shifted. In these cases, the cost of painting and maintenance should be taken into consideration.
Corten power lines poles can also blend into wooded areas, and they are sometimes required to get construction permits. When it is used on power lines, rust can get on the insulators and cause outages. To prevent flashovers, special designs are required. Corten performs best in very dry climates. It should not be used in humid coastal environments.
If you use corten steel with bolted connections such as towers, the corroding rust can cause the bolts to break. This is known as packing out
Reasons why Corten Steel is cheap
While corten steel is not necessarily inexpensive, it can be a cost-effective option in certain applications due to its unique properties. Known as weathering steel, corten steel is a low-alloy high-strength steel that forms a rusty appearance when exposed to the elements. In addition to providing a distinctive look, it also provides a protective layer against corrosion, making it a popular choice for outdoor sculptures, architectural cladding, and bridges.
Its durability and low maintenance requirements can make it more cost-effective than standard carbon steel in the long run, despite its higher initial cost. Corten steel’s rust-like appearance prevents further corrosion by adding a protective layer, which eliminates the need for additional coatings or maintenance. As a result, public works projects and other large-scale applications can benefit from lower maintenance costs and longer lifetimes.
There are several factors that can affect the cost of Corten steel, including the size of the project, the thickness of the steel, and the location of the supplier. Choosing materials should also take into account other factors such as structural requirements and design considerations, as Corten steel may not be suitable for all applications.
Uses of Corten Steel
Corten steel is a type of weathering steel commonly used in structural and architectural outdoor applications. The steel’s distinctive rusty appearance develops over time as it is exposed to the elements.
Corten steel is commonly used for the following purposes:
- Building facades: Corten steel is often used to create visually striking and unique building facades.
- Sculptures and art installations: Corten steel’s weathered appearance makes it a popular choice for sculptures and art installations.
- Occasionally, Corten steel is used in the construction of bridges and other infrastructure projects due to its corrosion resistance and durability.
- Due to its natural appearance and ability to blend in with the surroundings, corten steel is often used for landscaping features such as retaining walls, planters, and other features.
- Corten steel is an excellent material for outdoor furniture, such as benches, tables, and chairs, due to its durability and weather resistance.
Advantages of Corten Steel
The following are some of the benefits of using Corten steel in outdoor architectural and structural applications:
- Corten steel is highly durable and can withstand harsh weather conditions, making it a common choice for outdoor structures.
- Corten steel is corrosion-resistant, which means it won’t rust through like other types of steel. Instead, it forms a protective layer of rust that actually prevents further corrosion.
- Once installed, Corten steel requires little maintenance, making it a cost-effective option.
- Corten steel has a unique, rusty appearance that is often used for its aesthetic appeal. The material can add a rustic or industrial look to a building or landscape by blending well with natural surroundings.
- Corten steel is made from recycled materials and is recyclable itself, making it an environmentally friendly choice for construction.
Disadvantages of Corten Steel
Although Corten steel has several advantages, it also has some disadvantages:
- Because of its unique properties and production process, Corten steel has a higher initial cost than other forms of steel.
- Corten steel’s rusted appearance makes it attractive, but surrounding materials such as concrete or stone can be stained by it.
- In order to keep the surrounding area clean, Corten steel may require additional maintenance since it can stain surrounding materials.
- There may be limited availability of corten steel in some areas, and special orders or shipping may be required.
- Initially, Corten steel looks rusted. For some applications, the rusted appearance may not be desirable, and the desired patina may take time to develop.
