ГОСТ 18662-2023
Hot-rolled special interchangeable sections (SVP) for mine timbering. Dimensions
Full title and description
GOST 18662-2023 — Профили горячекатаные специальные взаимозаменяемые (СВП) для крепи горных выработок. Сортамент. (English: Hot-rolled special interchangeable sections (SVP) for mine timbering. Dimensions). The standard defines the assortment (dimensional series) and main designation parameters for hot-rolled SVP profiles intended for roof and wall support in mining openings.
Abstract
GOST 18662-2023 establishes the dimensional assortment, classification and basic parameters for hot-rolled special interchangeable sections (SVP) used in mine timbering. It replaces the earlier 1983 edition and provides normative references, terms and definitions, profile classification and the principal dimensions and tolerances required for manufacture and interchangeability. The document is primarily a dimensional/sortament standard rather than a materials or test methods standard.

Scope
The standard applies to hot-rolled special interchangeable profiles (SVP) intended for supporting mine workings. It specifies the assortment (series of profile types and sizes), main geometric parameters, classification and marking conventions necessary to ensure interchangeability and correct selection for mining support systems. The standard does not principally set metallurgical composition or mechanical testing procedures — those are covered by other normative documents referenced within the text.
Key topics and requirements
- Defined assortment and dimensional series for SVP hot-rolled sections used in mine timbering (profiles by designation and principal dimensions).
- Classification system and marking rules for interchangeability and identification.
- Nominal sizes, sectional parameters and tolerances (main parameters required for manufacturing and acceptance).
- Normative references and cross-references to related GOST documents (for example, referenced standards such as GOST 26877 and older GOST 18662-83).
- Guidance for application in mining support assemblies (selection by application and interchangeability considerations).
Typical use and users
Primary users are mining companies, underground support system designers, steel mills and rolling-mill manufacturers producing SVP sections, procurement and quality departments in mining and construction firms, and regulatory/standards bodies. The standard is used to order, produce, verify and interchange hot-rolled SVP profiles for mine timbering.
Related standards
GOST 18662-2023 supersedes ГОСТ 18662-83. It includes normative references to other metal-product and profile standards (for example, references such as GOST 26877 appear in the normative references list). Users should check related GOSTs for material grades, mechanical properties and testing methods where those are required.

FAQ
Q: What is this standard?
A: GOST 18662-2023 is the Russian national standard that defines the assortment (dimensional series), classification and principal dimensions of hot-rolled special interchangeable sections (SVP) used for supporting mine workings (mine timbering).
Q: What does it cover?
A: It covers profile designations, dimensional series, main sectional parameters and tolerances, classification and marking rules to ensure interchangeability of SVP profiles for underground support. It is a dimensional (sortament) standard rather than a metallurgical specification.
Q: Who typically uses it?
A: Mining operators, support-system designers, rolling mills and profile manufacturers, procurement and QA teams in mining/construction, and standards/regulatory bodies use this standard when specifying, producing or inspecting SVP profiles.
Q: Is it current or superseded?
A: It is current (in force). GOST 18662-2023 was registered in February 2023, published in April 2023 and came into effect on 1 August 2023; it replaces ГОСТ 18662-83.
Q: Is it part of a series?
A: The document is a standalone national sortament (dimensional) standard for SVP profiles; it belongs functionally to the suite of metal-product/profile standards within the metallurgy ICS classification (steel profiles and related GOSTs). Related documents address materials, testing and other technical requirements.
Q: What are the key keywords?
A: SVP, hot-rolled sections, mine timbering, dimensional assortment, steel profiles, interchangeability, GOST 18662-83, Rosstandart.
