Hi there, Just got a wholesale supplier selling E-glass fabric here, they do offer 600g per sq. meter and 800 g per sq.m. So what’s the density in terms of oz? Thanks for your attention. Regards, Crabie http://surfinglive.com/video.cfm?c=39&b=2

Crabie - Are you sure those numbers are right? 1 square meter = 1.1960 square yard. 600 gm = 21.18 oz. 800 gm = 28.24 oz. If my calculations are correct, that would be roughly 17.7 and 22.6 ozs per square yard respectively - much heavier than what is being used on surfboards (4-10 ozs per square yard)

Actually, it seems the density of the cloth 600 and 800 g per sq meter is pretty hefty? The conversion factor is 1 oz/sq yard = 33.9 g/sq m. But consider for ‘4 oz’ glass we have, 1 oz = 28.35 g 1 sq yard = 9 sq foot 1 sq foot = 929.0 sq cm 1 sq cm = .0001 sq m So, 1 sq yard = 9(929.0)(.0001) sq m = .8361 sq m 4 oz/sq yard = 4 (28.35 g)/.8361 sq m = 4 (33.9 g/sq m) = 135.6 g/sq m So 600 g/sq m = 600 (1/33.9 g/sq m) = 17.7 oz/yard or 18 oz cloth? Though it might actually be just the right ticket for that crowded day board… people would quickly learn to fear you. Kevin

Really heavy cloth you got there. I’ve just realized how heavy 6oz cloth was after first buying it. Up untill now I’ve only used 2oz cloth for ding repair. 2oz is great for staggered layers, you avoid the thick cloth edge. 4oz = 135g pr. m^2 6oz = 200g pr. m^2 regards, Håvard

Thanks, 600 g/sq.m is really really thick than what I m using. I m planning to buy e-glass from China, my friends told me this stuff is really cheap in there, may be around US$ 0.5 per yard~~~~~~~… Regards, Crabie > Really heavy cloth you got there.
