GOST 34028-2016 PDF

Full title and description

ГОСТ 34028-2016 — «Прокат арматурный для железобетонных конструкций. Технические условия» (English: Reinforcing rolled products for reinforced concrete constructions — Specifications). The standard establishes technical requirements for hot‑rolled and thermomechanically processed reinforcing bars (smooth and deformed) used in precast and monolithic reinforced‑concrete structures, including grades for ordinary and prestressing reinforcement.

Abstract

GOST 34028-2016 is an interstate (GOST) technical specification that consolidates and updates prior national rebar standards. It defines product grades, mechanical and chemical requirements, dimensional tolerances, profile geometry, weldability and testing/marking requirements for reinforcing steel used in buildings, bridges and other reinforced‑concrete structures. The standard aims to improve reliability (including for seismic, marine and cyclic‑load applications) and to harmonize requirements across participating states.

General information

• Status: Active / in force (Interstate standard, introduced as a national standard in the Russian Federation).
• Publication date: Adopted December 8, 2016 (GOST 34028-2016); introduced as a national standard of the Russian Federation from 1 January 2018.
• Publisher: Interstate Council for Standardization, Metrology and Certification (adopted as an interstate GOST); implemented/authorized for Russia by the Federal Agency for Technical Regulation and Metrology (Rosstandart).
• ICS / categories: 77.140.15 — Steels for reinforcement of concrete (steel products for concrete reinforcement).
• Edition / version: GOST 34028-2016 (current edition: 2016).
• Number of pages: Approximately 46 pages (PDF text versions commonly distributed are in the mid‑40s page count).

Scope

The standard applies to reinforcing bars (smooth and periodic/deformed profiles) of classes such as A240, A400, A500, A600 (and, for prestressed applications, Ap600, A800, A1000), intended for use in reinforcement of precast and monolithic reinforced‑concrete structures. It covers requirements for manufacture (hot‑rolled and thermomechanical processing), chemical and mechanical properties, geometric and surface characteristics, testing, marking, packaging and documentation. It replaces earlier GOSTs and consolidates requirements to support modern construction needs.

Key topics and requirements

• Designation and classification of reinforcing bar grades (A240, A400, A500, A600; Ap600/A800/A1000 for prestressing).
• Chemical composition and guaranteed mechanical properties (yield strength, tensile strength, elongation) for each grade.
• Profile types (smooth and deformed/ribbed), rib geometry and dimensional tolerances.
• Requirements for hot‑rolled and thermomechanically strengthened production routes and related property classes.
• Weldability and additional properties (including enhanced requirements for seismic, marine and cyclic applications where specified).
• Inspection, sampling and test methods (mechanical testing, chemical analysis, bend/rebend, dimensional checks).
• Marking, traceability, packaging and delivery documentation requirements.

Typical use and users

Primary users are steel manufacturers and rebar producers, construction contractors, precast concrete plants, structural and bridge engineers, material testing laboratories, procurement/specification teams and regulatory authorities. The standard is used to specify and certify rebar supplied for residential, commercial, industrial, bridge and infrastructure projects where compliance with recognized technical requirements is required.

Related standards

GOST 34028-2016 was developed taking into account and replacing earlier national standards such as GOST 5781‑82 and GOST 10884‑94 and parts of GOST R 52544‑2006 (for hot‑rolled and thermomechanically treated bars). It is related to international test and product standards such as ISO 6935 (steel for reinforcement), ISO 15630 (test methods for reinforcing steel) and comparable regional standards (e.g., BS 4449, EN/ISO reinforcement standards).

FAQ

Q: What is this standard?

A: GOST 34028-2016 is an interstate technical specification that sets technical conditions (requirements) for reinforcing rolled products used in reinforced‑concrete construction (rebar). It consolidates and modernizes previous national rebar standards.

Q: What does it cover?

A: It covers grades and classes of reinforcement, chemical and mechanical properties, dimensional and profile requirements, manufacturing methods (including thermomechanical processing), testing and inspection procedures, marking, packaging and related documentation required for supply and acceptance.

Q: Who typically uses it?

A: Steel producers, rebar suppliers, structural engineers, concrete and precast manufacturers, testing laboratories, construction contractors, specification writers and regulatory bodies in countries that apply or reference GOST standards.

Q: Is it current or superseded?

A: It is current (in force) as the GOST edition of 2016 and was introduced as a national standard in Russia from 1 January 2018. It supersedes earlier GOSTs for reinforcing steel such as GOST 5781‑82 and GOST 10884‑94 and replaces parts of GOST R 52544‑2006 for hot‑rolled and thermomechanically strengthened bars.

Q: Is it part of a series?

A: GOST 34028-2016 is an interstate standard within the metallurgical/construction series and aligns with ICS classification 77.140.15 (steels for reinforcement of concrete). It is used alongside test‑method standards (ISO/EN/ASTM/other national standards) that specify sampling and laboratory procedures.

Q: What are the key keywords?

A: Reinforcing steel, rebar, rolled products, deformed bars, thermomechanical, A240/A400/A500/A600, prestressing grades (Ap600/A800/A1000), weldability, dimensional tolerances, testing, marking.
