CORTEN STEEL
Corten steel is characterised by a rusty surface . A special alloy of copper, nickel and
chromium has been added to the steel . The means that the surface quickly forms a
layer of rust . At the same time, the corrosion time of the steel underneath the surfa-
ce is strengthened and prolonged by up to 8 times .
The rusty red colour will build and change over time depending on the weather . In
dry weather, it will be dark and dull; in rainy weather, shiny brownish .
TIPS TO QUICKLY BRING OUT THE RUSTY RED COLOUR
Your new HWAM Outdoor product has not yet developed its rusty patina when you
buy it . It will take approx . 14 days of rain for the surface to rust . Depending on the
weather, the patination process may take longer .
If you are a little impatient and would like to speed up the rusting process, you can
do the following:
•
Wash all surfaces in plain soapy water to remove any oil residues from when
the product was produced .
•
Let the surfaces dry .
•
Then you can spray the surfaces with salt water (1/20) or vinegar, or apply it with
a cloth .
The acid in the vinegar accelerates the rusting process of the washed-down
sides and shortens the process to approx . 3-4 days .
We do not recommend using strong detergents, as this may shorten the life-
time of the product .
MAINTENANCE
Please note that rust may rub off on and discolour the ground; it may also rub off
when you touch it . Rust can be removed from concrete tiles with oxalic acid (100 g of
oxalic acid to 1 litre of water) . Rub at the stain and rinse with clean water . Rust stains
on surfaces are also bleached by the sun .
