¡Û Fine Expanded Metals(Precise expansion metal) - Precision extract hand metal for EMI RFI handling in a variety of areas requiring ventilation and visibility. [characteristics of Precise expansion metal] • Outstanding Cost Performance in Mesh • Superior EMI Shielding Performance • Excellent electrical conductivity • Outstanding opening and visibility up to 90% • Welding and soldering is possible without taking off the ends 
1) Name and dimension of each part - LWD: Diagonal(long side) dimensions of a diamond The center distance of the next joint from one joint. The dimensions are determined by foam and are parallel to the width of the coil. - SWD: Diagonal (short side) dimensions of a diamond The center distance of the next joint from one joint. This dimensions may vary depending on the form. Because the width of the strand and the degree of tension change. As the level of tension increases, the number of webs per unit length decreases. 2) Thickness of used metal The thickness of the small plate to be the material of the extended metal can be set freely between the maximum and minimum production values, but the small plate actually used is 0.002/0.003/0.008/0.010 inches typical.
3) Strand Width The strapped width is the dimension of the spacing between slit and metal plates. This width is precisely adjusted and the width determines the weight and overall thickness. Generally, the width of the strands is equal to or greater than the thickness of the metal plate used. The width of the strand changes according to the degree of tension. For example, with fewer people, the strait width increases.
4) Maximum Sheet Width This plate width shows the maximum width of the sheet metal currently being sold for the designation of each extended metal. This width can be customized for future improvements or requests.

¡Û Woven Mesh - Mesh The unit for the size of the mesh is called "mesh". Indicates the number of mesh cords on the side of the side of 25.4 mm (1 inch). - Wire diameter Line diameter. The value of the Aperture width value mesh may vary depending on this. - Aperture width The length between the line and the line. Indicates the size of mesh space. - Pitch The length between the skirt key and the line seam is called the pitch. Indicates the foreground+aperture width. - Open screening area When viewed from the front, the percentage of space on the mesh is referred to as the spatial ratio. Space rate(%) = Marked as 100x(Aperture width¡ÀPitch)2
