- Corten Steel Structural Sections is a weathering steel grade according to EN 10025-5 / ASTM A588 for sustainable, decorative, and cost-efficient structures with uncoated steel sections。
- Self-protecting, durable and attractive, weathering steel is ideal for a whole range of outdoor structures in exposed locations including bridges, buildings and catenary gantries on railway lines
- educed construction cost along with construction time
- reduced cost of maintenance as well as time of maintenance operation
- no environmental impact due to absence of maintenance operations and residue
-
Weather resistance
Because Corten steel is highly weather-resistant, it can be used without painting. Paintless applications not only have the economic advantage of reducing repainting costs, but also provide aesthetic benefits associated with a calm color that protects the rust layer. The weather resistance depends on the product grade and the use environment. The weather resistance of Corten steel is 4-8 times that of ordinary steel.
-
Solderability
Trace amounts of alloying elements such as copper (Cu) and chromate (Cr) are added to Corten steel to ensure high weather resistance while reducing the carbon content to provide proper weldability. Corten steel can be welded by manual welding, gas shielded welding or submerged arc welding. In addition, spot welding can also be used for thin thicknesses of weathering steel.
-
Processability
Corten steel has similar processing properties (cold forming, hot forming and gas cutting) as ordinary steel of the same strength. For strip rolled products, it is best to bend the axis transversely to the main rolling direction. For applications requiring higher formability, steels complying with EN10155 can provide guaranteed changeability.
- The steel grades with the best weather resistance are S355JOWP, S355J2JOWP and Corten A. However, due to the use of cinnamon as an alloying element, the impact strength of these steel grades is lower than that of other weathering steels. These weathering steels are best suited for steel plate structures where there is no risk of brittle fracture.
- When the risk of brittle fracture must be considered in the design due to high material thickness, low operating temperatures or other reasons, it is better to choose other EN 10155 steels or Corten B. In this way, the impact strength requirements of hot-rolled steel can be consistent with the impact strength requirements of general steel structures.
- At temperatures above 540°C, S355J0WP, S355J2WP, Corten A and Corten B have significantly higher spalling resistance than general structural steel.
