GOST 25772-83 PDF

Full title and description

ГОСТ 25772-83 — "Ограждения лестниц, балконов и крыш стальные. Общие технические условия" (English title: Steel guardrailing of stairways, balconies and roofs. General specifications). The standard defines types, basic dimensions, technical requirements, surface quality, marking, packaging, storage and transport rules for steel guardrails used on stairways, landings, balconies and roofs.

Abstract

GOST 25772-83 (adopted 1983, effective 01 January 1984) establishes uniform technical requirements for steel railings and protective barriers for building stairs, balconies and roofs: classification by application, design types, mandatory dimensions (including minimum heights by application), structural and surface quality requirements, load/performance criteria (references to applicable load standards), and rules for manufacture, marking, packing, storage and transport.

Scope

The standard applies to steel guardrails for stairway flights and landings, balconies and roofs of buildings. It does not cover guardrails for steel stairs and platforms specifically. It sets out types by application (internal/external stairs, preschool institutions, balconies up to/above 30 m, roofs with or without parapet), required dimensions and limits for spacing and openings, performance and manufacturing requirements, and handling/transportation/storage conditions.

Key topics and requirements

• Classification of guardrail types by application: internal stair flights, external stair flights, preschool institutions, stair landings, balconies (for buildings up to 30 m and above), roof guardrails (with/without parapet) and smoke-free stair enclosures.
• Mandatory dimensional requirements (examples): typical overall heights H and internal handrail heights h — internal stairs ~900 mm, external stairs ~1200 mm, preschool railings ~1180 mm; balcony and roof heights vary by building height (examples and tabulated values provided in the standard).
• Structural/load requirements: guardrails must meet load and strength criteria referenced to then-applicable building loading rules (e.g., SNiP / СНиП load provisions); roof guardrails and balcony guards have defined service loads and resistance requirements.
• Material and fabrication references: requires compliance with related GOSTs for steel and coatings (e.g., GOST 23118-78 and others where applicable), welding and joining practices, surface finish quality and absence of defects (no scale, rust, cracks, burrs).
• Marking, packaging, storage and transport: procedures for marking, protective packing, stacking with wooden spacers, storage conditions and transport rules are specified (including climatic/storage categories by GOST 15150 and handling precautions).

Typical use and users

Used by architects and building designers for specifying safe railings; structural and metalwork manufacturers/fabricators producing stair, balcony and roof guardrails; building inspectors and code compliance officers; contractors and maintenance teams responsible for installation and periodic inspection of protective barriers in residential, public and industrial buildings.

Related standards

Commonly referenced documents include building loading and safety standards (SNiP/SNIP provisions such as СНиП 2.01.07-85), material and welding standards (for steel and coatings), GOST 9818-85 (dimensional references), and the modern replacement GOST 25772-2021 which formally replaces this 1983 standard.

FAQ

Q: What is this standard?

A: GOST 25772-83 is a Soviet-era national standard that specified general technical requirements for steel guardrails used on stairways, landings, balconies and roofs.

Q: What does it cover?

A: It covers classification of guardrail types, mandatory dimensions and spacings, structural and surface quality requirements, references to load/resistance rules, and rules for manufacturing, marking, packing, storage and transport.

Q: Who typically uses it?

A: Architects, structural and metalwork engineers, stair and railing manufacturers, building inspectors, contractors and facilities maintenance teams use the standard for design, fabrication and verification of steel protective railings.

Q: Is it current or superseded?

A: It has been superseded — GOST 25772-2021 replaces GOST 25772-83 (the newer standard took effect in 2021). For current regulatory or design use, consult the 2021 edition and any national/local building codes that reference it.

Q: Is it part of a series?

A: It belongs to the set of construction and metal-structures standards (ICS 91.080.10) and is used alongside related GOSTs and SNiP regulations addressing loads, steel materials, welding and protective coatings.

Q: What are the key keywords?

A: Guardrails, railings, stairway, balcony, roof, steel, dimensions, safety, GOST 25772-83, rail height, load requirements.
