Hello, I’m thinking of building a metal gate with vertical wood panels based on the attached sketch. This is my first time building one. I’m have a few questions. Should I use 14g or 16g posts? How deep should I dig the post and how much cement should I use? I live where there is not freezing. Left post will be attached to the house. Should I use two or four hinges on the door. Do you have recommended hinges? Should I use 14g on the hinge side of the door? I want to use a regular door handle and dead bolt on the gate. Thanks.
