Not all fences are created equal in terms of protection. Some may look great but lack structural integrity. Others may offer strength, but diminish your property’s curb appeal.
In this guide, Iron Fence Shop breaks down the two most secure fencing materials available: wrought iron and aluminum. Each is engineered for strength, weather-resistance, and aesthetic appeal.

Fully Welded Construction for Maximum Strength
When evaluating security fence strength, one of the most critical structural aspects is how the components are joined. Welding is a stable, fastening method because it produces a continuous bond between metal parts. Compared to bolted or screwed joints, welded connections better distribute stress and resist mechanical vibration, separation, or deformation over time.
Iron Fence Shop’s Stronghold Iron® fences are fully welded at every joint, picket-to-rail and rail-to-post, including all gate frames. This means your security fence will have no bolts or fasteners exposed that could potentially loosen, rust, or be pried apart.
Galvanized Steel and Powder Coating for Long-Term Rust Resistance
When exposed to oxygen and moisture, iron forms ferric oxide, commonly known as rust. Galvanization is a proven solution. In this process, the iron is dipped in molten zinc, which forms a protective zinc oxide layer that slows or prevents corrosion.
However, even with hot-dip galvanization, the rate of corrosion depends heavily on environmental factors. Salinity, humidity, and condensation cycles can significantly change how well galvanized protection holds up over time.
The table below illustrates how the corrosion rate of galvanized coatings can vary significantly depending on climate:
| Environment | Example Location | Observed Corrosion Rate |
| Industrial, coastal (moderate) | Los Angeles, CA | ~1.6 µm/year |
| Industrial, coastal (severe) | Abu Dhabi, UAE | >5 µm/year |
| Inland, arid | Phoenix, AZ | <1.0 µm/year (estimated) |
Galvanized surfaces in Abu Dhabi have been reported to corrode at more than 5 µm/year, while similar coatings in Los Angeles, a city with a comparable environmental type, corrode at only 1.6 µm/year. That’s over three times the rate, underscoring how seemingly minor differences in climate can lead to drastically different outcomes in durability.
Each Stronghold Iron® fence component is hot-dip galvanized to shield it against rust. Then, the metal is given a TGIC (triglycidyl isocyanurate) polyester powder coating for additional protection. This finish includes UV fade inhibitors and resists chalking, fading, and oxidation, helping the security fence maintain both its appearance and structural integrity, no matter where your property is located.
Finial-Topped Pickets for Perimeter Security
One of the simplest ways to deter potential intruders is vertical fencing with pointed tops. Spikes or finials on pickets are particularly effective, both as a visual signal of high security and as a physical barrier to climbing.
Our Stronghold Iron® fences come standard with welded, sand-cast iron finials on each picket, never glued or bolted on. This security fence design not only maintains its original position over time but also ensures it can’t be easily removed or damaged. The classic spear-top appearance adds to the security fencing’s deterrent effect without altering its residential or architectural appeal.
Customizable Heights and Styles for Your Specific High Security Needs
Fence height and picket configuration are relevant factors in fence security standards. For instance, residential homes with pets or children may prefer fences over four feet, while commercial spaces and high-risk areas may want five to six feet or more to prevent unauthorized access.
Iron Fence Shop offers fence panels in heights ranging from 3’ to 6’ and in two material thicknesses, Traditional and Signature Grades. This allows customers to choose from different types of security fences to match their site conditions. Add alarm systems and security cameras, and you have the perfect setup.
We also provide specialty designs such as the Rackable Classic style, which can accommodate property slopes without compromising coverage, and Puppy Picket style, featuring additional lower pickets to prevent small pets from slipping through. These style options allow property owners to fine-tune their security fencing based on terrain, inhabitants, and local regulations. A run-of-the-mill barbed wire or chain link fence simply couldn’t compare.

Aluminum Fence
Aluminum may be lighter than iron, but it’s far from lightweight when it comes to security fencing. Thanks to its natural resistance to rust and modern protection coatings, aluminum security fences offer a robust solution for your security needs.
Iron Fence Shop’s Infinity Aluminum® fences deliver a smart balance of strength, safety, and low-maintenance durability, ideal for families, pool enclosures, and properties needing high security without heavy upkeep.

Secure Panel Construction with Routed Posts and Welded Finials
Security fences rely heavily on how securely the panels are attached to supporting posts. In less advanced security fence designs, panels are mounted using exterior brackets, which can be loosened over time or compromised if exposed to impact or weather, even if you follow proper installation instructions.
Iron Fence Shop’s Infinity Aluminum® fences are built using routed posts that are matched precisely to the shape of the horizontal rails. This locked-in panel system reduces the chance of post detachment and visibly hides bracketry, further minimizing access points for intruders. Each picket includes a welded, sand-cast aluminum finial for consistent strength and finish. They are perfect for both residential and commercial properties.
Rust-Proof Protection for Long-Term Security
Aluminum is widely used in structural applications because of its natural corrosion resistance. When exposed to air, it forms a thin oxide layer that helps protect the metal beneath. However, this natural barrier can break down in challenging environments such as coastal and high-humidity areas, where additional surface treatment becomes essential for long-term protection.
“In harsh environment, aluminum must be chemically treated to provide enhanced protection.”
— Ron Liu, An Overview of Aluminum Protective Coating Properties and Treatments (University of Arizona)
Iron Fence Shop enhances aluminum’s natural advantage with a multistage cleaning process followed by the application of a TGIC powder coat infused with UV inhibitors. This coating not only helps prevent rust but also protects the surface from fading, chalking, and chemical wear, ensuring the security appeal of the fence remains consistent for years.
These aluminum panels benefit homes with swimming pools and commercial properties in coastal environments, spaces where all-weather resistance is non-negotiable.
Powder-Coated Finish Against Weathering and Fading
UV radiation and moisture exposure are common contributors to security fence deterioration over time, even if you do regular maintenance. While rust may not be a concern for aluminum security fences, surface degradation, such as chalking or fading, can reduce the protective coating’s effectiveness.
Each Infinity Aluminum® panel is coated with a TGIC powder coat finish. Homeowners who choose Infinity Aluminum® benefit from a consistent color and finish that holds up under daily sun exposure, helping preserve the fence’s look and security performance over its lifespan.
Good Security Fence for Those with Kids and Pets
Home security fencing is not only about keeping threats out with a formidable barrier with anti-climb spikes. It’s also about keeping loved ones safely inside with more user-friendly designs.
Picket spacing, fence height, and top-rail design all affect how secure a new security fence is for children and small animals. Security fences without sharp protrusions or horizontal footholds may be ideal for areas where climbing risk or injury is a concern.
Infinity Aluminum® fence’s Smooth Top design is especially well-suited for environments where safety and security go hand-in-hand. With no pickets sticking through the top rail, the design prevents snagging or accidental injuries across the fence line and provides a safer surface if a child or pet comes into contact with the security fence.
