A new picture-based app offers inspectors, architects and engineers a clear visual guide to surface conditions and other critical information when evaluating hot-dip galvanized steel.
The app, developed by the American Galvanizers Association (AGA), aims to assist professionals "who may be unfamiliar with the specific outcomes of the galvanizing process with a visual example of a surface condition similar to one they are viewing for their particular project,” according to AGA Executive Director Philip Rahrig.
Each image in the app is accompanied by text identifying the industry term for the surface appearance, detailing how and why it occurs, and noting whether or not it is accepted according to the specification.
The app also contains critical specification (ASTM, ISO, AASHTO) information to assess compliance with coating thickness requirements, as well as information on how to conduct repairs.
“Although approximately 3.5 million tons of structural shapes, plate, fasteners, and tubing are hot-dip galvanized each year in the US and Canada, the design of products and the chemistry of steel being galvanized yields an array of results which are often misinterpreted," said Rahrig.
"This app provides an immediate understanding of surface conditions, which makes it handy when there is an inspection question.”
The app is available for purchase for $4.99 in both the Apple and Google Play stores and through AGA at galvanizeit.org/mobile.
Founded in 1933, the AGA is a non-profit trade association dedicated to serving the needs of after-fabrication galvanizers, fabricators, architects, specifiers, and engineers.
