When working with galvanized steel, there are additional details and questions that some may have about the planning and design process of the project. So, we have decided to put together a list of our top 8 technical galvanizing tips we have observed over the 60+ years.
Tip #1: Not all galvanized coatings are the same. Most have significant differences in the thickness, hardness, and fullness of the formula.
Tip #2: Brushing, sweeping, or ‘whip’ blasting helps to provide an excellent basis for painting over galvanized coatings.
Tip #3: To avoid white rust formation, keep the packed work dry and treat the surface with proprietary water repellent or barrier coatings to prevent moisture contact with the galvanized surface.
Tip #4: To minimize distortion during the hot-dip process, consider the hanging requirements. This will ensure that the fabrication is adequately supported throughout the process.
Tip #5: Reduce strain-age embrittlement by choosing steels with low transition temperatures – coldworking raises the ductile-brittle transition temperature and galvanizing (heating) may raise it further.
Tip #6: Avoid notches as they increase stress. Notches may be caused during shearing or punching operations.
Tip #7: If welding before galvanizing, an uncoated electrode should be used when possible to prevent flux deposits on the steel or product.
Tip #8: When cleaning galvanized steel, apply and remove cleaning product according to manufacturer’s instructions and rinse with fresh water (twice recommended).
Now that you have read through these few tips, you should be able to know more about the process, what you should and shouldn’t be doing, and how to properly take care of your galvanized steel project.
