Practicality for Different Metals (Aluminum, Steel, etc.)
Steel Fences. Regular steel is prone to rust, so choosing the right protective coating is critically important. Galvanized steel already has a basic anti-corrosion layer (zinc coating), but a polymer finish significantly extends its lifespan. For steel fences (such as profiled sheeting, metal picket fences, or wrought iron sections), a matte coating is often the better choice due to its durability. Matte polymer is thicker and provides steel with longer-lasting protection against rust. If the fence is in harsh conditions (near roads with de-icing chemicals, in humid climates, near the sea, or close to chemical plants), a matte finish is definitely the best option. It will keep the steel intact for longer and prevent deep corrosion. Glossy coatings are also used on steel structures and can perform well, but they require more attention to paint condition. It is necessary to regularly inspect a glossy fence: as soon as a scratch or chip appears, it should be repainted immediately, or the exposed steel will start to rust. Overall, for a steel fence that is meant to be “set it and forget it” for many years, a matte coating is the more practical choice.
Aluminum Fences. Aluminum does not rust in the traditional sense (it does not develop red rust, only a thin oxide layer), so corrosion resistance is less dependent on the finish type. Aluminum fence sections are usually coated with powder paint for decorative purposes and additional protection. Both finishes—glossy and matte—adhere equally well to aluminum and protect it from oxidation. Essentially, the difference between matte and glossy coatings for aluminum comes down to aesthetics and ease of maintenance. Since aluminum is highly weather-resistant and can last for decades without deterioration, the choice of coating does not significantly affect its lifespan. However, aluminum is softer than steel, so strong mechanical impacts (such as dents or bends) can leave marks regardless of the coating. In terms of scratches, if the paint layer is damaged, aluminum will not develop rust spots, only slight surface dulling. Glossy powder coatings on aluminum are often used for a more “classic” look (e.g., white or green glossy fences), while black and gray aluminum fences are now mostly made with a matte/satin finish for a modern aesthetic. The choice here depends on yard design: both types of coating provide equal protection for aluminum.
Other Metals. For galvanized steel (e.g., chain-link fences with zinc coating), colored paint is often not applied at all—gray matte zinc itself acts as a protective layer. If galvanized mesh or panels are painted, PVC-polymer (matte green, etc.) or enamel is typically used. In such cases, matte/satin coatings are preferred since they adhere better to rough zinc. Wrought iron fences (welded grids) are traditionally finished with black glossy enamel to enhance the metal’s texture and protect against the elements. However, recently, many people opt for black matte for wrought iron sections—it looks more understated and hides scuffs better. Ultimately, both coating types work for most metals, depending on the desired look. Steel needs the most protective layer (where matte wins), while aluminum allows for a purely aesthetic choice.
