As you will see from these photos below all these gates made by myself or another worker are solid and will not distort in any way. They are also made in a way that cladding the gates is easy because I have incorporated fixing points for rails. I thought about a good system for many years until I started making these. The beauty about this design is that kids can swing or hang of them. You can give them a serious knock with a car and they will still be integral. The steel is over size for ecstatic rather then strength.
This gate or external doors I made in 2005. Yes, they need to be oiled. They are doweled and epoxy resin sealed. The masonry fence I hand mixed with my friend after I formed the sections. It is solid as. A car once crashed into it, only chipping a block. There was no sign of other damage the footings are 1.2 meters deep and it is 250 mm wide and reinforced with steel bars and mesh.
