GB/T 38232-2025Steel wire rope net panels for engineering (English PDF)

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 supersedes GB/T 38232-2019 "Steel Wire Rope Mesh for Engineering Use". Compared with GB/T 38232-2019, except for structural adjustments and weaving... Aside from the logical changes, the main technical changes are as follows.

---The reference to GB/T 2828.1 terms and definitions has been removed (see Chapter 3 of the 2019 edition);

---The technical requirements for wire rope coating have been revised (see 5.1.2, 2019 version of 5.1.2);

---The requirement for the diameter of the wire at the winding node has been removed (see 5.2.1 in the 2019 version);

---Added technical requirements for the thickness and corrosion protection of fastener nodes (see 5.2.1);

---Added technical requirements for the positive and negative tolerances of the mesh side length (see 5.3.1);

---Added requirements to the durability quality certification documents to specify the specifications, coating type, and grade of the wire rope (see 5.3.2);

---The visual inspection requirements for wire rope netting have been revised (see 6.3.1, 2019 version 6.3.1);

---The inspection rules have been changed (see Chapter 7, Chapter 7 of the 2019 edition).

This document is modified to adopt ISO 17746:2016 "Definition and technical specifications of wire rope mesh panels and rolls".

This document has undergone significant structural adjustments compared to ISO 17746:2016.A comparison of the structural numbering changes between the two documents is provided below. See Appendix A for the table.

This document differs significantly from ISO 17746:2016.The relevant clauses are indicated in vertical margins.

Single lines (|) are indicated. A summary of these technical differences and their causes can be found in Appendix B. The following editorial changes have been made to this document.

---The standard name has been changed to "Steel Wire Rope Net for Engineering".
