There are several type of mesh able to use in this type of design,
1. PYH-RR simi flexible mesh,
    The twist angle depend on the space between rods, the larger the space, the bigger the angle.
2. Welded Ring Mesh Curtain,
     Easy to twisted in very big angle, welded rings can ensure no breakage. Need to consider the Tensile Strength on installation.
3. PYH-EM expanded metal mesh,
     Able to twisted in big angle, but process need to be careful.
