When you first start looking for a gate, you will find that they are generally organised in sales catalogues according to their intended location - side gates, entrance gates, drive gates, for example. It is the location of gates that influences their design, and a complimentary gate and fence makes a property appear well cared for.
Gates can be expensive if they are made to last: wooden gates are often made of softwoods for economy but, for such a focal point of your home, it's worth investing in oak or cedar types. Wrought-iron gates are, in fact, made from mild steel, which must be primed and painted to protect them from rust and decay. Whatever type or style of gate you choose, it is vital that they are mounted on sturdy posts or masonry piers.
