Take a look at our selection of mounting supplies and you’ll find a lot of them are made of galvanized aluminum. Galvanized aluminum is lightweight, strong, and corrosion-resistant. But why is that so important, and what is galvanizing anyway?
Galvanizing is the process of bonding a thin layer of zinc onto another metal, typically aluminum or steel. It can be thought of as “painting” zinc on and it can be done several ways. The most important part to know is that you’re not creating a coating that can scratch off, you’re creating a permanently bonded part of the product.
It’s important to make a tripod or some other mounting item corrosion-resistant, because if it were to corrode then it would become weaker and eventually fall apart. Obviously we don’t want that…
…but if corrosion-resistance is so important, you’re saying to yourself, why isn’t galvanized aluminum used on antennas as well? The zinc coating of galvanized aluminum is much less sensitive to radio transmissions than regular aluminum. On the other hand, aluminum oxide is almost as receptive to transmissions as pure aluminum, so a little oxidation is ok on an antenna, especially on the parts that do the receiving because they don’t have to bear the weight of the structure.
Let’s also look at the weight part of the issue. Aluminum is lighter than steel and that really doesn’t matter a lot for you when you install it, but it cuts down on shipping costs and that makes it really important to us at Solid Signal, because we want to offer products to you at fair prices. We pay shipping costs to bring items into our warehouse, and you pay to get things delivered. Lighter is always better when it comes to shipping. Aluminum is nearly as strong as steel but a lot lighter.
Generally, galvanized parts have that weird patchwork pattern you see in the photo above, but they don’t always have that pattern so you shouldn’t worry if you don’t see it. It could be hard to detect or just not present. The pattern is formed due to the way the galvanization takes place.
