ILZRO Classifications of Sandelin Steels

Research carried out by the University of Cardiff in Wales for ILZRO (International Lead Zinc Research Organization) project took an in-depth look at the problem of silicon reactivity and included phosphorous as a reactive element also. The researchers varied the weight percentage of silicon and phosphorous and then assessed the reactivity of the steel at different galvanizing temperatures. This work led to a table of reactivity clas...

Weld Slag Clean Up Requirements for Galvanizing

When welded structures are hot-dip galvanized, the weld area cleanliness significantly affects the quality and appearance of the galvanized coating around the weld.  If a coated electrode (i.e. a flux-coated welding wire/rod/stick) is used during welding, all welding flux and slag must be cleaned prior to galvanizing or the ...

Contact Relations Management

I am one of the few remaining users of a Palm Pilot. About 15 years ago, I put together what I believe has been a very effective contact management system utilizing a Palm Pilot, ACT Contact Management Software, e-mail and a fax software integration program. This combination has served me well for many years. Unfortunately, unlike the fundamentally sound hot-dip galvanizing process, information technology changes at a rapid rate. While there a...

Can non-members get technical support from the AGA?

One of the benefits of being a member of the American Galvanizers Association (AGA) for galvanizers is free unlimited technical support. The AGA technical staff will answer questions pertaining to the galvanizing process and job-specific problems such as appearance or other issues. Some of the dues AGA members pay goes to the cost of researching technical problems. Because of this, ...

Is it safe for food to be in contact with galvanized steel?

For most foods, contact with galvanized steel is perfectly safe. Only acidic foods should not come in contact with galvanized steel according the the U.S. Food & Drug Administration. The acid in some foods reacts with the zinc coating to form salts that are readily absorbed by the body and in excess could cause a very mild sickness. So, where is galvanized steel used ...

How much does galvanizing cost?

Due to the relatively stable price of zinc and technology /process efficiencies in the last 20 years, hot-dip galvanizing has steadily become more competitive, and often less expensive, on an initial basis than other corrosion protection systems. To compare the cost of hot-dip galvanizing to other protective coatings, please use the online
