Products Description
Corten steel, also called Weather Resistant steel or Atmospheric Corrosion Resistant steel, it is known as a low cost and highly effective material.
Corten steel is classed as being a "self -protecting "steel for its "patina "which results from protective surface oxidation and develops during exposure to the atmosphere; The oxide layer that gives the steel its distinctive appearance and enhances weather resistant capabilities compared to standard steels, also the improved corrosion performance can lead to improved service life.
Corten steels are typically used in Railway, bridges, rolling stock, shipping container, Garden building, and other structural applications.

FAQ
Is corten steel toxic to humans?
No, Corten Steel is not toxic. These environment-friendly materials are completely safe for humans, animals, and plants.
How can you tell if steel is Corten?
Corten Steel undergoes a gradual weathering process so that you may notice signs of ageing, such as rust accumulation and colour changes over time. These visual cues indicate that the steel is indeed Corten and not a standard steel with surface rust.
Can I weld corten steel?
You can weld corten steel in various ways: electrode, MIG/MAG, and TIG. To achieve a nice and durable result, you must use the right welding wires and materials.
Does corten steel get hot?
Do corten planters get too hot in the summer? Steel planters have the ability to conduct heat and may feel warm to the touch after being exposed to the sun.
Do magnets stick to corten steel?
The 316 and 304 stainless steel that we sell is austenitic and therefore will not attract magnets. Which Steels are Magnetic? Other than austenitic stainless steels, most steel does attract magnets. Galvanised steel, Corten steel, mild steel, cold-reduced steel and hot-rolled steel are all magnetic.
