Inspection of hot-dip galvanised steel is a straightforward and expeditious process. Inspection will focus on two essential properties of the galvanised coating: its thickness, and its overall appearance and surface condition. Various physical tests can be conducted to assess these aspects, providing invaluable insights into its thickness, uniformity, adhesion and visual appeal.
Galvanised products adhere to stringent, industry-wide standards. ISO 1461 is the British standard for hot-dip galvanised coatings on iron and steel articles in the UK and Ireland.
It specifies the general properties of coatings and test methods for coatings applied by dipping steel articles.
This comprehensive standard covers various facets of galvanising processes to ensure consistency and quality across the industry — for instance, minimum coating thickness requirements across product categories and specifications regarding zinc metal composition used during galvanising processes.
Adherence to this stringent standard assures customers and industry professionals that galvanised steel fulfils defined performance and quality criteria, providing a reliable framework to assess its longevity and inspiring confidence in its ability to provide excellent corrosion protection and aesthetic appeal.
