Why Is Corrugated Metal Low-Maintenance?

One of the key advantages of quality corrugated metal is its low maintenance requirements. The corrugated metal panels we use in roofing and siding, and the metal fence panels we use in our wood framed fences boast several protective features. Rejoice over the savings of time, effort, and money maintaining your fence!

Wood fences, vinyl fences, and other materials all have their place and their own beauty. Each has its benefits and drawbacks. While metal may sometimes be a little heavier and sometimes a little costlier, its benefits are numerous.

The life of a well-made corrugated metal product can be 40 years or more. Physically and at the chemical level, they possess several defenses.

Defense One: Galvanization

The first protective element in corrugated metal fencing is galvanization. Galvanization protects metal, particularly steel and iron, from corrosion. Our steel wire, metal roofing material, and steel fencing panels are treated through hot-dip galvanization. This is a process of immersing cleaned steel in a bath of molten zinc at a temperature of around 450°C (842°F).

At this temperature, the iron in the steel reacts with the molten zinc to form zinc-iron alloy layers. Upon withdrawal, the zinc coating solidifies, creating a characteristic crystalline pattern known as "spangle".

Barrier Protection

What does this mean for the life of the metal? The zinc coating now acts as a physical barrier shielding the underlying metal. This zinc layer prevents corrosive substances from coming into direct contact with the steel, inhibiting corrosion.

Sacrificial Protection

Zinc is more reactive than steel, which means it will corrode preferentially when exposed to corrosive elements. This sacrificial behavior of zinc protects the underlying steel even if the coating is scratched or damaged. The zinc essentially "sacrifices" itself to protect the base metal.

Cathodic Protection

Galvanization also provides cathodic protection to the steel. In the presence of an electrolyte (like moisture), the zinc coating acts as an anode while the steel becomes the cathode. This electrochemical reaction protects the steel from corrosion even if small areas of the coating are damaged.

Protective Patina

When exposed to the atmosphere, the zinc coating naturally weathers to form a protective patina. This patina, composed of zinc carbonate, further enhances the corrosion resistance of the galvanized coating. Galvanized steel can last for many decades in average environments.

Defense Two: Color Coating

Another protective layer, plus added beauty, is added when a panel is given a durable color coat. Commonly, manufacturers favor economy coatings like PE (standard polyester) and SMP (silicone-modified polyester). Longer-lasting high-performance coatings include PVDF (polyvinylidene fluoride) and HDP (high durability polyester).

HDP is a favorite here at BarrierBoss because it strikes a great balance between economic value and performance. HDP incorporates UV absorbers and HALS (hindered amine light stabilizers). HALS act like tiny defenders against sunlight. This helps prevent the coating from breaking down.

By extending the paint’s lifespan, you also preserve the panel beneath, not to mention keeping the color looking fresh. Check out these beautiful black metal fence panels:

Defense Three: Clean Routine

Though all these characteristics protect your fence with metal, it is still prudent to do small simple maintenance. This will ensure your metal fence product stays in good condition for the years to come.

• Periodically clean it with water and a mild detergent. This helps remove dirt, grime, and any buildup affecting the fence’s look and performance.
• Occasionally check the fence for signs of damage, such as dents or scratches. These areas are most prone to rust as they have exposed the metal underneath the coating. Addressing these issues promptly can prevent rusting or more serious problems.
• Apply a rust-inhibiting coating if you notice any signs of rust. This is particularly important in regions with high humidity or where the fence is exposed to saltwater.
• Ensure that screws and fasteners are tight and secure. Over time, vibrations and weather conditions can loosen these components, so it’s wise to tighten them as needed.

Long-Lasting Protection

By following these simple maintenance tips, you can extend the lifespan of your corrugated steel fence or corrugated galvanised metal roofing.

This explains why we believe corrugated metal makes the ultimate metal panel fence or sheet metal roofing material. If you are looking for a durable, low-maintenance, and trendy material, corrugated metal might a safe choice.
