I haven't heard of that brand of metal sheets, but there are other options for different size dye sub printers and the printing products are almost endless. You can print on many different types of products including metal, frames, mugs, shirts, keychains, etc. You can check out
http://unisub.net/ to view the possibilities.
If you're looking into printing the large metal sheets on your current printer, you may want to watch for the sheets as the CTP was the only model really made for doing this and the heater that came with the printer baked the ink on the sheets to help make many many prints (like a newspaper production).
Other customers have converted the 24" and 44" Epson models from Pigment to Dye to also go this direction. Epson than came out with their own Dye sub large formats which also store large amounts of ink to save on the cost of production.
Hope this somewhat helps. The other post is another option.
