Here are the poles for the soon-to-be-built 'new' gate. It is kind of a crappy pic, but I didn't have the room to actually separate the poles so that you could see them. 10' of 4x4 steel with 1/4" wall, weighing in at about 130lbs. each. They are completely protected from rust by POR-15. Actually, I first used POR-15, but since it is UV sensitive, I figured that I may as well coat it with their BlackCote, so that it doesn't look like crap in a year.
