Full title and description

GOST R 51285-99 — Twisted wire meshes with hexagonal cells for gabion constructions. Specifications. The standard sets technical requirements, classifications, dimensions, coatings and quality control methods for twisted hexagonal-wire mesh used in gabions, mattress and other mesh structures for bank protection, slope stabilization and rockfall/debris protection.

Abstract

This national standard of the Russian Federation specifies types, nominal cell sizes, wire diameters, permitted coatings (zinc, zinc‑aluminium alloys, polymer coatings), marking, packaging, acceptance rules and test methods for twisted hexagonal wire mesh intended for gabion constructions and related civil-engineering applications. It includes provisions for coating quality assessment and references relevant testing and marking norms.

Scope

This standard applies to twisted wire mesh with hexagonal cells manufactured for gabion constructions and other mesh structures used in hydraulic and geotechnical protection: bank stabilization, soil reinforcement, slope and embankment strengthening, protection against rockfalls, avalanches and debris flows. It covers mesh classification by cell size and wire diameter, types of permissible metallic and polymer coatings, basic tolerances and acceptance testing requirements.

Key topics and requirements

• Classification of mesh by nominal cell (mesh) size (N‑numbers) and corresponding wire diameters.
• Permitted wire materials and coatings: zinc galvanizing, zinc–aluminium alloy coatings, and polymer coatings; coating quality acceptance rules and tests for coating continuity.
• Dimensional tolerances for mesh geometry, wire diameter and cell size; requirements for edge/selvage wires and tying wires used in gabion fabrication.
• Acceptance testing methods, including immersion/electrochemical determination of coating mass and visual/mechanical checks to ensure coating integrity when twisted.
• Marking, packaging, transportation and storage requirements (references to applicable GOST norms for marking and packaging).

Typical use and users

Main users are manufacturers of gabions, civil and hydraulic engineers, contractors for river‑bank and slope protection, erosion-control specialists, and procurement/specification teams in infrastructure and environmental protection projects. The standard is used to specify supply requirements, to verify conformity of delivered mesh, and to guide selection of mesh type for particular geotechnical applications.

Related standards

This standard is commonly referenced together with other national standards for gabion products and wire materials (for example standards that specify gabion construction, edge/tie wire diameters, coating tests and packaging). It is used alongside product standards for gabion units and with testing/acceptance standards for metallic coatings and wire products.
