New CorTen finish option for ACO Threshold Drain
New ACO Threshold Drain CorTen finish
ACO is proud to announce the launch of an additional Threshold Drain in a new CorTen finish.
A one-metre channel and corner until will both soon be available. All of the current Threshold Drain accessories can be used on these new items.
The patina finish is being seen more and more in high-end garden and landscape projects, with products from planters to walls being offered by a range of manufacturers, the finish can enhance a space and textures felt and seen within it.
There are some specifics to consider when using this finish on a product; CorTen develops its characteristic rusty appearance after it has been exposed to rainwater, therefore new stocks may look black when first delivered. This surface, the so called patina is an oxidation layer that protects the metal from further corrosion. During formation of the patina, the rainwater may also get a rusty brown colour and therefore can leave stains when it comes into contact with other (porous) surfaces.
It is of great importance to install the channel 3-5mm below the adjacent paving level, such that during heavy rainfall, no water will flow back on the paving. When using very porous paving material and/or light coloured paving, it is recommended to allow the CorTen gratings to corrode on a safe location and only install them on the channels when the patina has fully developed.
ACO bears no responsibility for stains on paving when using CorTen gratings. In case of doubt, we recommend to use our aluminium gratings with this channel.
