Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 5330-2003 "Industrial Metal Wire Woven Square Hole Screens". Compared with GB/T 5330-2003, except for the structure... Aside from adjustments and editorial changes, the main technical changes are as follows:

---The values for the arithmetic mean size deviation of the mesh and the range of large mesh deviation have been changed (see Tables 1 and 2,.2003 editions of Tables 1 and 2);

---The description and requirements for weaving defects in metal wire braided square mesh have been revised (see 5.2.2,

4.6.3 of the.2003 edition);

---The maximum permissible number of major weaving defects in woven square mesh wire mesh has been changed (see Table 3, Table 4 in the.2003 edition);

---Added specifications for the tensile strength of woven square-hole metal wire mesh (see 5.2.9);

---The values for the wire diameter and limit deviations have been changed (see Table 5, Table 3 in the.2003 edition);

---The requirements for selecting metal wire have been changed (see 5.3.1,

4.5.1 in the.2003 edition);

---Added provisions regarding the permissible limits of the wire diameter (see 5.3.4);

---The regulations regarding the distance between the inspection location and the edge of the net have been changed (see 6.5,

5.4 of the.2003 edition);

---Added relevant provisions for evaluating the results of wire mesh testing (see 6.7, 6.8). Please note that some content in this document may involve patents.

1 Scope

GB/T 5330-2025 is the Chinese national standard covering woven wire screen cloth - the aperture series and the wire diameters that go with each, the tolerances on aperture size and on the count of oversize openings, the weave types, and the marking and inspection of a cloth used to classify material. At 25,000 words. It replaces GB/T 5330-2003, a standard twenty-two years old. In force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026, replacing GB/T 5330-2003.

This document specifies the weaving style and type of industrial metal wire woven square hole screens with basic mesh sizes ranging from 0.02mm to 16.00mm. Number and specifications, technical requirements, inspection methods, inspection rules, and marking, packaging, transportation, and storage. This document applies to the screening of solid particles, the filtration of liquids and gases, and the production of woven square-hole metal wire mesh for other industrial applications. Production, inspection and acceptance.
