New Thermal Spray Bridge Coatings Guide Now Available

A new free guide specification by the AASHTO/NSBA Steel Bridge Collaboration, Specification for Application of Thermal Spray Coating Systems to Steel Bridges (S8.2), is now available. The document provides guidance on shop metallizing steel girders and establishes and defines the functions, operations, requirements and activities needed to achieve a consistent quality. A collaborative effort was taken in the development of this document to ensure owners’ and applicators’ representatives have clearly defined roles and responsibilities. The guide is written in specification language so it can be adopted in whole as part of the project contract documents.

The Steel Bridge Collaboration is a joint effort between the American Association of State Highway and Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) with representatives from state departments of transportation, the Federal Highway Administration, academia and various industry groups related to steel bridge design, fabrication and inspection. The mission of the Collaboration is to provide a forum where professionals can work together to improve and achieve the quality and value of steel bridges through standardization of design, fabrication and erection.

This document and other guide specification documents from the Collaboration are available for free at
