Zinc and Acrylic Coating
McWane Poles’ standard arc-applied zinc and acrylic coating is expected to cover the ductile iron
pole surface for 40-50 years. Unlike galvanized steel, the integrity of ductile iron will not be in
jeopardy at the point when iron oxide shows through the coating.
Coated finish poles are protected with a two layer coating. The base layer coating is an arc-
applied zinc, deposited on the ductile iron pole surface to a minimum coverage equivalent to
0.08 grams per square inch per ISO 8179. The zinc layer is fused to the ductile iron and prevents
it from oxidizing. The arc-applied (also known as thermal spray) zinc method offers similar
protection as hot-dip galvanizing, and it is the preferred method for protecting ductile iron. An
acrylic barrier coat with a minimum of 4 mils thickness is applied on top of the zinc base coat.
The acrylic is bonded to the zinc, so it will never peel or flake.
The acrylic barrier coat is expected to cover the zinc base layer for at least 25 years. Eventually,
the acrylic coating will fade or dissolve, and the similarly colored zinc layer will be exposed. The
zinc layer is expected to cover the ductile iron for an additional 25 years.
Once the acrylic and zinc coatings are worn from the surface of the ductile iron, the natural or
“weathering” ductile iron pole is expected to last 50 to 75 years. McWane Poles offers a bare
ductile iron pole for sale, and this pole is expected to last 75 years in normal conditions.
Paint Information
Prior to field painting, wipe down the surface of the pole to remove loose dirt, oxides, oils, etc.
