GB/T 11264-2025Hot-rolled light rails (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 11264-2012 "Hot-rolled light rail", GB/T 11265-1989 "Joint plates for light rail", and GB/T 11266- 1989 "Light Rail Pads". This document is based on GB/T 11264-2012, and integrates GB/T 11265-1989 and GB/T 11266-1989. Compared with GB/T 11264-2012, the main technical changes, apart from structural adjustments and editorial modifications, are as follows:

---The steel smelting method has been changed (see 5.1,

5.2 in the.2012 edition);

---The grades of hot-rolled light rail, light rail pads, and light rail joint plates have been changed (see 6.1,

5.1 in the.2012 edition);

---The different requirements for chemical composition and mechanical properties of different types of hot-rolled light rails have been removed (Tables 9 and 10 in the.2012 edition);

---The permissible length deviation of hot-rolled light rails (see Table 7, Table 6 in the.2012 edition) and the requirements for end curvature (see 6.4.1.4.1) have been revised. Table 7 (2012 edition)

---Added dimensional inspection requirements for the "flatness of the rail bearing surface" of light rail pads (see Table 9);

---The chemical composition test methods for hot-rolled light rails, light rail pads, and light rail joint plates have been revised (see 7.4,.2012 edition). Table 11);

---Added batching rules for light rail base plates and light rail joint clamps (see 8.2). Please note that some content in this document may involve patents.

1 Scope

GB/T 11264-2025 is the Chinese national standard on hot-rolled light rails, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 August 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2026. Classification: ICS 77.140.70, CCS H44. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
