Wrought Iron, Steel, or Aluminum: Choosing a Gate Metal

Published July 1, 2026

Picking the metal is the decision that shapes how your gate looks, how much upkeep it needs, and how long it lasts. In coastal Mount Pleasant, where salt air reaches every 29464 backyard, the choice matters more than it does inland. Here is how the three common gate metals compare, and what to weigh before you commit.

Wrought Iron and Mild Steel

Forged iron and mild steel are the classic choice for a reason. They carry ornate scrollwork, pickets, and cast finials that lighter metals cannot, and they weld into a rigid frame that holds its shape across a wide driveway span. The trade-off is weight and rust potential. Steel must be primed and finished properly, because bare metal in Lowcountry air will corrode. Done right, a powder-coated steel gate looks sharp for many years.

Aluminum

Aluminum will not rust, which makes it the low-worry option near the water. It is light, so it is easy to automate and gentle on hinges, and it comes in powder-coat colors that mimic iron from a few feet away. It is not as strong as steel, so a very wide or heavily ornamented gate may still call for an iron frame. For a straightforward pedestrian or driveway gate, though, aluminum is hard to beat on maintenance.

Finish Is Half the Battle

Whatever metal you pick, the finish decides how it ages. We prime every welded joint with a zinc-rich primer, then powder coat or apply an enamel topcoat rated for coastal exposure. That layered finish keeps corrosion from creeping in at the seams, which is exactly where a cheap paint job fails first. A yearly rinse and a quick look at the hinges keeps any gate in good shape.

Match the Metal to the Job

A garden gate on a side yard has different demands than a motorized gate across the drive. Heavier automated gates lean toward steel frames for rigidity, while a simple walk-through can be aluminum.
