What is A847 steel?
A847 Tubing Commonly referred to as weathering steel, ASTM A606 Type 4 high-strength, low-alloy (HSLA) steel utilizes elements such as copper, chromium, nickel and silicon to enhance the protection and resistance to atmospheric corrosion.
What is weathering steel used for?
When is Weathering Steel Used? Because weathering steel can outlast plain carbon steel in outdoor conditions, it is frequently used for exposed steel structures. This removes the need for constant repainting and recoating of the steel. Examples include building and bridge construction.
How much is Corten steel?
How much is the Corten steel price per square foot? We started out by mentioning that the reported price of Corten steel is $2.50 to $3 per square foot You can often find 32 square feet panels starting at $70 or so, which in fact comes in at slightly under $2.5 per square foot.
What is A709 steel?
The ASTM A709 is the Standard Specification for Structural Steel for Bridges and encompasses carbon, high-strength low-alloy, and quenched and tempered alloy steels used as structural plates in the construction of bridges.
How expensive is weathering steel?
Yes, it is. Corten is significantly more expensive than other common grades of steel. Corten steel planters are easily 50%-100% more expensive than a similarly sized planter of another long-lasting material. Custom applications will cost even more, since they need to fabricated and then installed.
Can weathering steel be painted?
Can weathering steel be painted? While the corrosion resistant properties of weathering steel allow it to be used unpainted in structural and architectural applications, it CAN be painted. However, the surface requires proper cleaning, preparation and material to achieve a painted appearance.
Why is Corten so expensive?
Corten is significantly more expensive than other common grades of steel. Corten steel planters are easily 50%-100% more expensive than a similarly sized planter of another long-lasting material. Custom applications will cost even more, since they need to fabricated and then installed.
How long will Corten steel last?
Corten Steel and Rust Generally, Corten steel will patina or rust within 6 months of atmospheric exposure. Most weathering steel types need cycles of wet/dry weather to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.
What is the yield strength of HPS 50W?
Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 [250], 50 [345] or 50S [345S] without agreement between the purchaser and the supplier….1. Scope.

Does Corten steel stain concrete?
Cor-ten can be challenging and even damaging to surrounding areas if used improperly. Rust bleeding or runoff from the steel surface can stain surrounding paint, stucco, stone or concrete. Avoid using this material where staining can be a problem.
Can you paint metal without sanding?
Sanding and scraping the metal surface will make it smooth, uniform, and easier to paint. Any buildup or residue that was not removed during cleaning should be sanded away. Avoid using power tools for this stage, since they can actually polish the surface, leading to problems with adhesion when it comes time to paint.
