Drain holes in Hot-Dip Galvanized steel can be sealed quickly and economically without welding and the damage it will do to the galvanized surface.

be any thickness.)
Hole on left is 1-1/16” diameter.
On right a zinc 1-1/16” diameter plug
drops approximately 2/3 into the hole.
Pressure, either hammering or hydraulic
press will force the plug further into the
drain hole.

As it is driven into the hole, the malleable aluminum or zinc plug compresses and makes continuous contact with the 1/4” thick steel.
There will be some plug material showing above the steel surface. This can be removed by grinding or filing.
Area shown in red circle shows
where a Vent Hole Plug has been
installed.
With proper grinding the plug will
exactly match the height of the
surrounding surface. A light coating
of galvanize spray helps the repair
completely disappear.
Note: Both Aluminum and Zinc
Vent Hole Plugs are relatively soft,
malleable materials and grind very
quickly.
Plugs are available in Aluminum or Zinc
Aluminum from 1/4” diameter to 5”
