Powder coating a wrought iron fence can greatly diminish the amount of maintenance it needs. Right away there are clear advantages if you have the choice between the two. Unlike paint, which can have spots of buildup or dripping when first applied, powder coats are baked on for an even finish without the possibility of drips or pooling. As time goes on, powder coating won't chip or scratch the way paint eventually does. Powder coating also helps better protect wrought iron from the above mentioned environmental factors better than paint does.
Powder coating can last around 20 years and can be done in just about any color imaginable and in a variety of finishes from smooth to textured. You do not need to have a brand-new fence to benefit from powder coating. You can also refinish an old wrought-iron fence with powder coating to give it new life and longevity.
