GOST 27772-2021 PDF

Full title and description

GOST 27772-2021 — Rolled products for structural steel constructions. General specifications. The standard defines technical requirements, delivery conditions, marking, and normative references for hot-rolled flat, section and shaped rolled products and bent profiles intended for use in building steel structures (supplied in non-heat-treated, heat-treated or thermo‑mechanically treated conditions).

Abstract

GOST 27772-2021 establishes common technical conditions for a wide range of rolled steel products used in structural steelwork, covering product types, mechanical and chemical requirements, dimensional and geometric tolerances, testing and inspection, delivery states, marking and documentation. It replaces the previous 2015 edition and harmonizes delivery and quality rules for rolled products intended for welded and other connections in construction.

Scope

The standard applies to hot-rolled flat products (sheet and wide-strip universal), long products, shaped rolled sections and bent profiles produced from sheet rolling that are intended for manufacture of building steel structures with welded and other types of connections. It covers products supplied without heat treatment as well as those supplied in heat‑treated or thermo‑mechanically treated conditions; products manufactured to this standard may also be used for other applications.

Key topics and requirements

• Definition of applicable product types: hot-rolled flat, section, shaped and bent profiles intended for structural steelwork.
• Chemical composition and mechanical property classes (yield strength, tensile strength, elongation) for designated steel grades.
• Delivery conditions: untreated, heat-treated, and thermo‑mechanically treated states; requirements for marking and documentation on delivery.
• Dimensional tolerances, geometric requirements and permitted deviations for rolled sections and plates.
• Inspection and testing requirements, including sampling, mechanical and chemical tests, and acceptance criteria.
• References and normative links to other GOSTs and related technical regulations used for specific product types and tests.

Typical use and users

Used by steel producers, fabricators of building steel structures, structural engineers, procurement specialists, testing laboratories and conformity assessment bodies to ensure rolled products meet uniform technical and delivery requirements for construction applications. The standard is referenced in design and manufacturing specifications for welded and bolted structural assemblies.

Related standards

References include earlier edition GOST 27772-2015 (superseded), and numerous product‑ and test‑specific GOSTs cited in normative references (for example standards on steel grades, dimensional tolerances, test methods and profiles such as GOST 8239, GOST 8240 and others listed in the normative references).
