ISO 1461: Hot dip galvanized coatings on fabricated iron and steel articles, specifications and test methods
The reference for hot-dip galvanized fabricated steel.
Reference noteThis page is an independent plain-language summary written by QUALITAS TR. It does not reproduce the standard. Always work from the current official edition, available from ISO, the International Organization for Standardization, and national standards bodies such as TSE in Turkey (official page). QUALITAS TR supports organisations against this standard; it does not certify them.
01Purpose
ISO 1461 specifies general properties and test methods for hot dip galvanized coatings applied to fabricated iron and steel articles.
02Scope
Covers appearance, coating thickness (minimum local and mean values depending on article thickness), adhesion, and renovation of uncoated areas.
03Main requirements
- Visual appearance free of defects that impair use
- Coating thickness by magnetic method or other methods
- Thickness requirements depending on steel thickness
- Limits on areas that may be repaired and repair methods
04Typical applications and industries
Structural steel, fasteners, towers, solar structures and many outdoor products.
05Audit and inspection considerations
- Is thickness measured per reference area?
- Are repairs within limits?
06Common nonconformities
- Thin coating on thin sections
- Uncoated areas larger than allowed
- Ash and dross inclusions
07How QUALITAS TR can support
Checked in coating and galvanizing inspection.
