Due to the chemical composition of Corten Steel, a very dense oxidisation layer is formed during the weathering process which protects the blue steel inside. If this protective barrier is compromised, it will simply form a new skin to protect itself. Corten Steel is extremely durable and has a far higher resistance to atmospheric corrosion than other steels.
Step by Step Weathering Guide. Stage 1 - Freshly manufactured Corten Steel.At this stage the dark oily residue coats the Corten Steel. Stage 2 - The oily residue is beginning to break down, as the Corten Steel begins to weather.
Stage 3 & 4 - The Run-Off stage This can take around 3-9 months depending on weather and positioning. Stage 5 & 6 - The final stages of the weathering process. Some Run-Off may still occur as the Corten Steels patina develops to a striking, more consistent appearance. PH Levels If the water you will be using in your feature does not have a neutral PH level, the run off process will be prolonged and an ongoing residue may form.
As such, we suggest the use of a neutralising water supplement. Alternatively, the steel can be varnished with a rust oil, such as Owatrol. This should be carried out when the finish has developed to a satisfactory stage. We would still recommend maintaining neutral PH levels afterwards. Run Off During the weathering process the Corten Steel produces carbon run off or staining to adjacent materials such as stone or concrete.
To reduce this possible staining, we recommend raising the product up off the ground by using a suitable stand, blocks of wood, slabs and such like; this will prevent any direct contact with the flooring material. After the initial reactive period Corten Steel will cure and self-seal with little to no carbon run off. The weathering process of Corten Steel is integral to this product and as such we will not accept any responsibility for damage caused to surrounding materials as a result of carbon run off from Corten Steel products. Please ensure you do not place your product on any surface that may be damaged during the weathering process.During the run off stage the water in our water features may become discoloured, however this can be reduced by oiling or using an appropriate neutralising water supplement such as chlorine tablets.
