We supply flanges for data center cooling systems, fire suppression piping, and critical infrastructure. Hyperscale facilities require precision-manufactured flanges that meet demanding specifications for reliability and performance.
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.
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.
