I. Overview of GFW Wire Mesh

GFW metal wire mesh, also known as industrial metal wire woven square hole screen mesh, is a kind of screen mesh product made of stainless steel wire or other metal wires through plain weave, twill weave and other weaving processes. Its core standard is GB/T 5330-2003, which is widely used in fields such as screening, filtration, dust prevention and industrial support, and has the characteristics of acid and alkali resistance, corrosion resistance and high temperature resistance.

Ii. Types and Weaving Methods

Classified by weaving techniques

Plain weave: 1-400 mesh, pore size range 0.038-23mm, suitable for conventional screening and filtration.

Twill weave: 30-635 mesh, pore size 0.022-0.65mm, higher strength, suitable for fine filtration.

Mat type weaving: 7×40 mesh to 500×3500 mesh, hole diameter 0.001-0.35mm, used for ultra-precision filtration (such as medical and chemical industries).

Classified by material

Stainless steel series: 304, 316, 316L, 321, etc., with strong corrosion resistance, suitable for the food, pharmaceutical and chemical industries.

Special alloys: such as nickel-copper alloys, tin bronze, etc., are used in special environments (such as high temperatures, strong acids).

Iii. Specification and Model Analysis

Model marking rules

Adopt the format of "GFW+ Screen model + Material + Weaving method", for example:

GFW3.15/0.8-304 plain weave: Indicates 304 stainless steel plain weave mesh with a hole diameter of 3.15mm and a wire diameter of 0.8mm.

GFW0.8/0.28: Indicates a square mesh with a hole diameter of 0.8mm and a wire diameter of 0.28mm.

Key parameters

Mesh size: 0.02-16mm (standard range), and some precision meshes can reach 0.005mm.

Wire diameter range: 0.025-8.0mm, width supported: 0.6-2 meters (customizable to 20 meters).

Mesh size range: 1-2300 mesh, meeting different precision requirements.

Iv. Main Uses

Industrial screening

Mining and sand and gravel industry: Screening particles, such as the GFW6.3/1.8 model for coarse particle classification.

Petrochemical industry: Used as mud nets or acid-washed nets (such as 316L material, resistant to strong acids).

Liquid/gas filtration

Food and pharmaceutical: Filter impurities from liquids (such as GFW0.1/0.09 ultrafine mesh).

Environmental protection field: sewage treatment, air filtration.

Special applications

Decoration and protection: such as building crack prevention nets, mechanical equipment protection nets.

Electronics industry: Precision component screening (mat type woven mesh).

V. Purchasing Suggestions

Select the material based on the environment: 316L is preferred for acidic environments, and 310S is suitable for high-temperature scenarios.

Mesh size and pore size matching: For high-precision filtration, models with a larger mesh size and smaller pore size (such as GFW0.063/0.045) should be selected.

Customization requirements: For wide-width nets (over 2 meters), special processes are needed. It is recommended to communicate the wire diameter and load-bearing requirements in advance.

With its diverse models and outstanding performance, GFW metal wire mesh has become an indispensable functional material in the industrial field. Reasonable selection can significantly enhance production efficiency and product quality.
