Plugging Holes

Zinc Plug

During hot-dip galvanizing, steel fabrications are entirely immersed in corrosion-inhibiting molten zinc metal, resulting in unsurpassed corrosion protection of all interior and exterior surfaces. To allow for this thorough coating, holes in fabrications are often required. These holes allow for any or all of the following:

If needed or desired, holes can be plugged after galvanizing. If filler material other than zinc is used, there is a chance of accelerated corrosion in the localized area due to dissimilar metals in contact.

Consult your galvanizer to determine which filler material is best suited to meet your objectives.
