Introduction to models, types and national standards of metal wire mesh

National standard metal wire mesh models: GF1W, GF2W, GF3W metal wire braided square hole screens, etc.
GF2W refers to the industrial square hole level 2 precision screen. As the name suggests, there are also GF1W and GF2W, which are the industrial square hole level 1 precision screen and the industrial square hole level 2 precision screen. They are generally used for screening industrial solid particles. , and vapor and liquid filtration.
In R10-1.2, R10 refers to the mesh, including R20, R30, R40, etc., while 1.2 refers to the wire diameter.
Standard: All metal wires used are drawn in accordance with Q/90183-2002 standards. See the detailed parameter table for wire specifications. R10, R20, R20/3, R40/3 mesh screens are produced in strict accordance with the requirements of standard GB/T5330-1985. Hole series
Mesh size: 10mm-0.022mm (2-550 mesh)
Weaving form: plain weave, twill (2/2 twill, 2/4 twill, irregular twill, herringbone twill)
Material: high-quality brass, tin bronze , stainless steel, pure nickel, etc., the hole accuracy is graded 1.2.3.
Currently implemented wire mesh standards:
GB/T5329-1985 "Terminology for Test Sieves and Screening Tests"
GB/T5330-1985 "Industrial Metal Wire Braided Square Hole Screens" 
GB/T6003-1997 "Industrial Metal Wire Braided Long Holes Screen》  
GB/T5330.1-2000 "Industrial Metal Screens and Metal Wire Woven Mesh"
Purpose: Mainly used for solid particle screening, fluid filtration, decoration, dust prevention, skeleton support, etc.

Specifications:
1. Mesh series: adopt priority series R20/3, R10 series, supplementary series R20, R40/3, R40, select according to needs.
The size ratios in the series are as follows: R20/3--1.4, R10--1.25, R40/3-1.19, R20-1.12, R40-1.06
2. Mesh size: W =L ÷ n－d W—average mesh size . L—length of adjacent mesh W—average mesh size  
d—average diameter of metal wire
