GOST 7566-2018 PDF

Full title and description

GOST 7566-2018 — Standard specifying technical requirements, test methods and acceptance rules for rolled steel products intended for general engineering and construction purposes. The standard defines dimensions, tolerances, mechanical properties, marking and methods of inspection for a range of hot-rolled and cold-rolled steel sections and bars used in manufacturing and construction.

Abstract

This standard establishes the essential technical requirements for rolled steel products, covering types of sections and bars, their nominal sizes and permissible deviations, mechanical and chemical property limits, surface quality, marking, packing and methods of sampling and testing. It is intended to ensure consistent quality and interoperability of rolled steel in industrial and construction applications.

Scope

Applies to rolled steel products intended for general engineering and construction uses. It sets requirements for dimensional accuracy, mechanical and chemical properties, surface condition, marking, packing and documentation, and specifies methods for sampling and testing. The standard is intended for manufacturers, inspection bodies and users to ensure product conformity with established quality levels.

Key topics and requirements

• Definitions and classification of rolled steel products (bars, sections, profiles)
• Nominal sizes, tolerances and permissible deviations for dimensions and shape
• Mechanical property requirements (yield strength, tensile strength, elongation) for specified steel grades
• Chemical composition limits or reference to relevant steel grade specifications
• Surface quality requirements, permissible defects and acceptance criteria
• Sampling procedures and required laboratory test methods (mechanical, chemical, dimensional)
• Marking, packing, transportation and storage instructions
• Rules for product certification, inspection and acceptance by the consumer

Typical use and users

Used by steel manufacturers, rolling mills, quality control and inspection laboratories, procurement specialists, construction companies, mechanical engineers and regulatory bodies. The standard is referenced in manufacturing specifications, contracts, quality assurance procedures and acceptance testing protocols for rolled steel used in building structures, machinery components and general fabrication.

Related standards

Often used together with other national and sector standards covering specific steel grades, heat treatment, welding compatibility and corrosion protection. Related documents typically include GOST standards for chemical analysis, mechanical testing methods, and specific GOSTs for particular product types (bars, sheets, angles, channels). It may also reference international norms for steel product testing.
