Hot-dipped Galvanizing is an in-depth process whereby the steel is primed, removing excess mill scaling, dirt, and debris that accumulates on the metal including any rust particulates that have accumulated on the surface. This accumulation of particulates on the surface is known as the surface profile. NACE International and the Society of Protective Coatings, as well as, the ASTM International Standard (American Society for Testing and Materials) offer further information on the acceptable standardized practices.
Your Plans call for Blasting and Priming – what you need to know?
Why Blast and Prime?
Do your construction drawings call for blast and prime or galvanized material? There is a significant difference between the Blast and Prime (B&P) process and Hot-dipped galvanizing. Blasting metal for preparation of a primer application is necessary to ensure that the metal primer adheres to the surfaces successfully preventing chipping and erosion of the paint. When we don’t follow this process, the paint will wear faster and so more maintenance will be required.
