This feels like a bit of a stupid question but as I'm not sure of the answer I'll ask anyway...

Is it possible to buy 'natural-looking' silver-grey fence panels that look similar to the following?

The reason I ask is that all the panels I'm seeing available have been treated with something that has quite a heavy pigment and, as such, quite often have a deep orange colour to them.

The panels above are ~12 years old and so I have no doubt that their silver-grey appearance will primarily be down to weathering, particularly UV-induced fading, but I am wondering if it is possible to get something at least close at the outset? I may need to replace a couple soon and I really don't want some bright orange affairs as they'll stick out like the proverbial sore thumb.
