Need help with a Carrier Deck

I finished a Dauntless, and while it looks good with the cardboard Verlinden Carrier Deck, I would like to create a little more accurate represention of an actual deck. http://www.accurate-miniatures.com/gallery/sbd/html/keeley.htm The wood portions are not really a problem it is the steel grating? that has me baffled. Is there a method of creating it or does someone sell it. I have another dio that I'd like to start depicting a zero taking off. I'm also looking for details on Japanese Carrier Decks as well.

Thanks in advance for all your help.
