does anyone recognize this type of steel deck?

Hi all, We are adding a deck to our parlor level and having a hard time finding one that works. I have a hard time walking on surfaces that aren’t closed up and most of the options my contractor are very open. I know I can cover with ipe or something, but we won’t be able to do that right away. This picture is of my friends deck who can’t remember anything besides it being steel. Any help would be greatly appreciated!
