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

What are the models, types and national standards of GB wire mesh?
GB wire mesh models: GF1W, GF2W, GF3W metal wire woven square hole screen, etc.
GB wire mesh production implementation standard: GB/T5330-2003 replaces the original GB/T5330-1985 standard
GF2W refers to industrial square hole 2-level precision screen. As the name suggests, there are GF1W and GF2W, that is, industrial square hole 1-level precision screen and industrial square hole 2-level precision screen, which are generally used for industrial solid particle screening and gas-liquid filtration.
In R10-1.2, R10 refers to the mesh size, including R20, R30, R40, etc., and 1.2 refers to the wire diameter.
Standard: All metal wires used are drawn according to Q/90183-2002 standard. The wire specifications are shown in the detailed parameter table. R10, R20, R20/3, R40/3 screens are produced strictly according to the requirements of standard GB/T5330-1985. Screen
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 divided into 1.2.3. Levels.
The currently implemented wire mesh standards:
GB/T5329-1985 "Test Sieve and Screening Test Terminology"
GB/T5330-1985 "Industrial Metal Wire Woven Square Hole Screen"
GB/T6003-1997 "Industrial Metal Wire Woven Long Hole Screen"
GB/T5330.1-2000 "Industrial Metal Screens and Wire Meshes"
Application: Mainly used for solid particle screening, fluid filtration, decoration, dust prevention, skeleton support, etc.
National Standard GB Metal Wire Mesh Specifications:
1. Mesh Series: Use the priority series R20/3, R10 series, and the supplementary series R20, R40/3, R40, and select according to needs.
The size specifications 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 meshes W—average size of meshes d—average diameter of metal wire
Value table of L and N:
Mesh size (mm) Measuring length (L) (mm) Measuring number of meshes n
16.0-2.80 Check the length of 10 adjacent meshes
2.65-1.18 Check the length of 20 adjacent meshes
1.12-0.50 Check the length of 30 adjacent meshes
0.45-0.15 Number of adjacent meshes of 10mm
0.14-0.071 Number of adjacent meshes of 5mm
0.067-0.022 Number of adjacent meshes of 3mm

GF2W refers to industrial square hole 2nd level precision screen. As the name implies, there are also GF1W and GF2W, namely industrial square hole 1st level precision screen and industrial square hole 2nd level precision screen, which are generally used for industrial solid particle screening and gas-liquid filtration.
In R10-1.2, R10 refers to the mesh size, including R20, R30, R40, etc., and 1.2 refers to the wire diameter.
Standard: The metal wires used are drawn according to the Q/90183-2002 standard. The wire specifications are shown in the detailed parameter table. R10, R20, R20/3, R40/3 screens are produced strictly according to the standard GB/T5330-1985.
The mesh size of the mesh series is 10mm-0.022mm (2-550 mesh)
Weaving form: plain weave, twill (2/2 twill, 2/4 twill, irregular twill, herringbone twill)
