I've just received an order for 3000 nails for a nail gun that I intend to use for a closeboard fence. I ordered galvanised nails and expected them to have the familiar rough grey coating. But the one that turned up have a gold looking finish that's much smoother than the galvanised finish that I would expect. I've put one of the nails in a shallow tray of water to see if it rusts - nothing yet!
My question to the floor: Are these really galvanised? Is this a new technology that I'm not familiar with?
