Wire diameter(MM)
Aperture/Opening size(MM)
Length(M)
Width(M)
Mesh count(N/INCH)
1)Plain weave & Twill weave
Kg/roll=wire diameter*wire diameter*mesh count*width*length/2
2)Plain Dutch Weave & Twill Dutch Weave & Reverse Dutch Weave
Kg/roll=weft wire diameter*weft wire diameter*weft mesh*width*heigth/4+warp wire diameter*warp wire diameter*warp wire diameter*warp mesh*width*length/4
3)Mesh count=25.4mm/(wire diameter+aperture)
4)Aperture=25.4/mesh count-wire diameter
5)Open area(%)=wire diameter*wire diameter/(wire diameter+aperture)²*100%
