I am trying to find the first time we used metal meshes as platforms, like in the image above. I though that a good starting point would be to find the moment metal meshes were created.

Unfortunately, my usual trip to http://en.wikipedia.org/wiki/Mesh for answers did not bring any references or further hints.

    Welcome to History.SE! Are you asking for when a metal mesh was first used or when it was first used as a platform? – Reliable Source Feb 3 '13 at 13:02

Steel grating for platform use was first developed and produced by Walter Irving at the beginning of the 20th century. It was first used for ventilation of New York's stiflingly hot subway system, but his company, Irving Subway Grating, quickly marketed it for a range of other uses including bridge decking and catwalks. Aluminum grates (which might be what's shown in the picture) came later.
