Architectural Designs II

Capabilities and Limitations of Architectural Metals and Metals for Corrosion Resistance II (14057b)

By Catherine Houska, originally published as two separate articles in The Construction Specifier, Part 1, reprinted from October 2000 issue and Part 2, November 2000. Part 1. Metal has become increasingly popular because if provides unique design opportunities, strength and corrosion resistance. Each metal family has unique characteristics. Performance over time depends on the designer understanding the advantages and limitations of each metal and taking these into consideration during the design process. Part 2. Predicting a metal's performance in exterior applications, soil, or concrete requires knowledge of the factors influencing corrosion. Unfortunately, good comparative corrosion data for different metals can be difficult to obtain. Research reports comparing service environments and the performance of different metals are usually written by and for metallurgical engineers. This article summarizes published data and other selection citeria so non-metallurgists can take advantage of available research.
