GOST 34180-2017 PDF

Full title and description

GOST 34180-2017 — Steel, cold‑rolled and cold‑rolled hot‑dip galvanized thin sheet with polymer (prepainted) coating applied by continuous coil‑coating (roller) processes. Technical conditions and delivery specifications for prepainted coil‑coated steel intended for construction, appliance panels, instrument engineering and related industries (non‑automotive applications).

Abstract

This standard sets technical requirements, test methods and acceptance criteria for continuously coil‑coated polymer prepainted cold‑rolled and cold‑rolled hot‑dip galvanized steel sheet. It covers substrate and metallic coating types, organic coating systems (paint, plastisol, etc.), mechanical and surface properties (adhesion, bend/impact/strength, hardness, gloss, colour contrast), inspection and marking, and conditions for delivery and acceptance. The standard was approved in 2017 and published in 2018.

Scope

Applies to cold‑rolled and cold‑rolled hot‑dip galvanized thin steel sheet that is prepainted by continuous coil‑coating (roller application or laminating) with polymer systems. The standard specifies permitted substrate/coating combinations, surface preparation, coating application parameters, mechanical and appearance requirements, test methods for adhesion, gloss, hardness, bending and impact resistance, and conditions for supply and acceptance. It is intended for building materials, exterior panels for household appliances, instrument engineering and other industries excluding automotive, unless otherwise agreed between supplier and purchaser.

Key topics and requirements

• Definitions of substrate types and metallic coatings: zinc, iron‑zinc, zinc‑aluminium, zinc‑aluminium‑magnesium and similar hot‑dip coatings when agreed.
• Specification of organic coating types used for coil coating (paints, plastisol, PVDF and related systems where applicable) and nominal film thicknesses.
• Mechanical and performance requirements: adhesion (cross‑cut and other methods), bend test, impact resistance, strength tests and hardness (pencil method).
• Appearance and durability criteria: colour contrast, gloss measurement, visual defects acceptance and resistance to environmental factors.
• Test and inspection methods, sampling and acceptance rules; references to national test methods (for example adhesion testing standards).
• Packaging, marking, documentation and delivery conditions for coils and cut lengths.

Typical use and users

Manufacturers of coil‑coated steel and metal processors, steel service centres, architects and façade/cladding installers, manufacturers of household appliance exteriors, building material suppliers and quality laboratories. Procurement and quality assurance teams use the standard to specify material acceptance criteria for prepainted steel used in construction and industrial applications.

Related standards

Closely related international and national documents include EN 10169 (continuously organic coated / coil‑coated steel — technical delivery conditions) and test‑method series such as EN 13523; ASTM specifications for polymer precoated steel (e.g., ASTM A742); and other GOST documents governing metallic coatings and test methods (for example GOST 14918 on hot‑dip galvanized sheet and GOST 31149 for adhesion testing). These standards are commonly cross‑referenced when specifying substrate, coating and test protocols.
