Due to the metal’s low density and ability to resist corrosion, it has become a popular choice as lightweight, durable fence and railing structure.
The amount a fence panel can rack is determined by the size of hole punched on the horizontal rails to accommodate pickets.
The coating is applied through an electrostatic process and cured under heat to form a strong smooth surface.
Its weather resistant quality leads many manufacturers to offer very long warranties, from decades up to "lifetime" for some brands.
Aluminum fencing didn’t become popular in the residential world until 10–15 years ago as it was more expensive and the benefits were lesser known.
