ASTM A123 Galvanizing Overview
Bottom line: ASTM A123/A123M addresses zinc coatings on iron and steel products by hot-dip galvanizing. The base product, fabrication state, coating requirement, touch-up/repair requirements and project specification should be coordinated before coating.
What it tells the buyer
ASTM A123/A123M addresses zinc coatings on iron and steel products by hot-dip galvanizing. The base product, fabrication state, coating requirement, touch-up/repair requirements and project specification should be coordinated before coating.
What it does not decide
It does not automatically determine the correct size, grade, finish, fabrication, coating, code compliance or application suitability for a specific project.
What to put on the RFQ
State the current specification designation/grade, product form, dimensions, quantity, processing, documentation and any project-specific requirements.
Send a cleaner RFQ
Provide the project specification or drawing when the standard is owner/engineer controlled.
Reference starting point: ASTM International — use the current purchased/authorized edition of the applicable specification. Always verify the current governing standard, approved project specification and manufacturer documentation before final procurement.
