Trying to get some dates for when certain metal roof sheeting profiles commenced manufacture. Specifically when did the Klip-lok metal roof sheeting profile come into being, and when did zinc aluminium coatings start being manufactured. Can you assist? Even a generic date (eg 1930's) would be sufficient Kind regards Marc Joyce [email protected]		Guest User 10/1/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12143/find/
Zinc aluminum coatings had their origination in the 1960s I believe. Snap-lock standing seam started in the 1980s I believe.		Todd Miller Isaiah Industries, Inc. 10/7/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12144/find/
