If you plan to install a steel main gate, opt for the stainless steel material to prevent it from rusting. The normal grade of stainless steel used for making gates is 304, and this kind of stainless steel is non-magnetic in nature. Therefore, you can check for it by using a magnet, although this simple method of checking is not fool proof.
When I installed my stainless steel main gate, here are the few preferred features:
- Pattern of the grille rods should be plain and simple. I have chosen the simplest smooth rods without pattern or carving, because its price is cheaper, and it is easier to clean and polish.
- Make the bottom part of the gate to have grilles put closely together, to prevent cats and dogs from outside entering into the house, and also to prevent your pets from escaping away from your house.
- Make a door in one of the gates for easy access, especially if you plan to install autogate system.
You can see the stainless steel main gate of my house from the photo in my other post - Car compass on dashboard. That picture was taken when the car is parked in the carpoach of my house.
