Question on blue print symbols?

This is not my normal job and I'm struggling with a set of commercial concrete floor plans trying to get some info. to my estimator who's away on vacation. Question: Does anyone know what type of steel reinforcement is being required with the following?: WWF 6X6-W1.4xW1.4 I think its wire mesh?...but I'm not sure about the gauge? Secondly, regarding rebar placement what exactly does the symbol #4@18" E.W. mean? I know their talking about 1/2" rebar, but I'm use to seeing the symbol O.C. for "on center," and I'm not sure about the symbol E.W.? Any advice would be greatly appreciated. Thanks!
