Frequently Asked Questions

What is hot-dip galvanizing?+

Hot-dip galvanizing immerses the flange in molten zinc at approximately 840 degrees F, creating a metallurgically bonded zinc coating that provides decades of corrosion protection.

Does galvanizing affect flange dimensions?+

The zinc coating adds approximately 2-5 mils of thickness. Bolt holes may need to be chased after galvanizing to ensure proper fit. ASTM A153 specifies minimum coating thickness requirements.
