As with any project or material, installing wrought iron fencing has advantages and disadvantages. Some pros and cons of this fence material include:

Pros

• Long lifespan with proper maintenance

• Very durable

• Aesthetically pleasing

• Functional as well as decorative

Cons

• Requires regular maintenance and cleaning

• Expensive compared to other fence materials

• Limited privacy

Moisture and rot are the largest threat to wooden fences. Stain can help your wood fence last 15 to 20 years, but only if you choose a stain with waterproofing qualities or add a sealant. Oil-based stains create a thicker moisture barrier than water-based stains, though both are mold and mildew resistant. You’ll generally need to re-stain your fence every one to eight years to get full protection.

You can use a few different tactics to prevent your deck gate from sagging. Aside from using strong, rot-resistant woods, introducing a diagonal element—such as a tension rod or solid piece of wood to act as a brace—across the gate will offer better support. You can also use rigid joists to prevent the gate from sagging.

Privacy fences in residential neighborhoods tend to stand between 6 and 8 feet tall, but local building code usually dictates the maximum height. Livestock fences that border large land plots range from 3 to 6 feet. Shorter, decorative fences, which are common in front yards, are around 3 feet tall, on average. Fence height also tends to vary by material, with wood fences usually sitting at 6 feet tall, and chain-link and wrought iron fences tending to sit at half that.
