Hot Dip Galvanizing Spec

AASHTO/NSBA Steel Bridge Collaboration Releases Galvanizing Guide Specification

The following information was provided by the National Steel Bridge Alliance.

Developed by the AASHTO–NSBA Steel Bridge Collaboration, S8.3 Hot-Dip Galvanizing Specification presents information and practices for owners, designers, and fabricators for specifying hot-dip galvanizing of steel bridges and other highway structures, which provides a durable protection from corrosion.

The specification includes best practices for design and fabrication, as well as information on:

  • Material properties of hot-dip galvanizing
  • Types of materials suitable for hot-dip galvanizing
  • Welding considerations and procedures
  • Venting and draining
  • Distortion control

The specification also presents information related to other zinc coating processes, including mechanical galvanizing, electroplating, and metalizing.
