As Brittany stated earlier, we only use hot-dipped galvanized in this application. It is not a code issue but it does make a huge impact on quality and what will be seen for years to come.

The correct nail to be used is a Hot dipped galvanized nail. Nail diameter and size are different on all applications . A regular galvanized nail is only electo galvanized meaning as soon as the driver from the vail gun strikes the nail that part is no longer galvanized . Always use hot dipped for all aplications and you'll be safe. Sometimes We have to go repair entire houses where siders us the electro galvanized instead of paying the $10 more for the correct nails and you will see the nail heads actually rusting. Great question though. Hoped this help. www.greenbuiltwa.com
