This practice covers procedures that can be followed to safeguard against the possible embrittlement of steel hot-dip galvanized after fabrication, and outlines test procedures for detecting embrittlement. Conditions of fabrication may induce a susceptibility to embrittlement in certain steels that can be accelerated by galvanizing.

Important Design and Fabrication Considerations for Hot Oct 24, 2018 · Hot-dip galvanized steel (also referred to as batch or after-fabrication galvanizing) is a coating process to line metal in corrosion-resistant zinc. After steel fabrication, the metal is cleaned to remove grease, oils, and mill scale lying on the surface.
A duplex system is simply painting or powder coating steel that has been hot-dip galvanized after fabrication. When paint and galvanized steel are used together, the corrosion control provided is superior to either system used alone. The galvanized coating protects the base steel, supplying cathodic and barrier protection.
