The Nickel Development Institute, Toronto, (416-591-7999) publishes a
Directory of Stainless Steel Products for Building & Construction (reference
Book 11016). One of the lists is organized by products (angles, bolts,
channels, pipes, tubes, wire, etc.). Let me know what you are looking for,
and I'll fax you some pages from the directory -- my copy is from 1996.
Also, the Specialty Steel Industry of North America, www.ssina.com may have
some information you can use.
