Everything You Need to Know About Galvanized Metal

websitebuilder • May 24, 2019

Selecting metal for the product you are manufacturing or the building you are constructing is one of the biggest decisions you need to make. The type of metal you select can affect the lifespan, durability, and type of maintenance that your product or building can require. It can also affect your budget and costs associated with your project.

Learning about the various types of metal that are on the market can help you determine which metal is ideal for your metal product or building. Read on to learn more about galvanized metal and everything you need to know if you are considering using this type of metal.

What Is Galvanized Metal?

Galvanized metal is metal that undergoes the galvanization process. The galvanization process is the process of applying a thin coating of zinc to different types of metals. Different methods are used to galvanize metal, including hot dipping, pre-galvanizing, and electrogalvanizing.

You can tell that metal is galvanized when it has a pattern to it that is known as a spangle pattern. A spangle pattern almost looks like someone dipped a sponge in gray paint and then sponge-painted the metal. You’ll notice darker and lighter spots, much like you would see when a wall is sponge painted.

What Types of Metal Can Be Galvanized?

Iron and steel are the two most common types of metals that are galvanized. However, they are not the only types of metal that can receive this treatment.

Most ferrous metals are able to be galvanized, while most non-ferrous metals are not able to be galvanized. If you are unsure if a metal is ferrous or non-ferrous, a magnet can help enlighten you. If a magnet sticks, you have a ferrous metal. If the magnet doesn't stick, you are dealing with a non-ferrous metal.

What Are the Advantages of Galvanized Metal?

Galvanization is primarily performed to prevent your main metal material from rusting or corroding. When a layer of zinc is added to a sheet of metal, the zinc itself will rust or corrode. While this may sound like a negative, it is actually a positive.

Since the zinc is rusting or corroding, it is preventing or slowing the more expensive and vital metal from rusting or corroding. This helps to protect your more important metal source from the damaging effects associated with rust and corrosion.

Helping to slow or protect against rust and corrosion can help extend the lifespan of your metal and reduce the amount of maintenance the metal may need.

The other major benefit associated with galvanized metal is that the zinc coating is long-lasting. You can purchase many products and sealers to protect your metal against rust and corrosion. Many of these coatings wear off in a matter of years due to weather exposure. Zinc can last upwards of 50 years, which prevents you from having to coat your metal again in the future.

Are There Any Drawbacks to Galvanized Metal?

One of the biggest drawbacks to galvanized metal is that the galvanization process helps to hide imperfections, flaws, and problems with the metal. As such, you may miss problems with metal that require immediate repair or maintenance.

Another drawback to galvanized metal is that the coating is not always smooth. When it is used inside of pipes, it can lead to items getting stuck on the rough surface, which leads to blockages and obstructions within the pipe.

The boiler of an espresso machine stores the water that's used to pull shots and steam milk. Boilers are made of metal, and the ideal metal conducts heat, doesn't corrode, and is affordable. Manufacturers of espresso machine boilers use several metals that offer these properties to varying degrees. Learn about the pros and cons manufacturers weigh when they choose which metal to use. Aluminum Aluminum is widely used in entry-level espresso machines, for manufacturers prioritize cost over other factors in these machines. Cheap stovetop espresso machines, inexpensive steam-powered machines, and budget pump machines might all have aluminum boilers. The biggest benefit of aluminum is that it doesn't drive up the cost of these machines. Aluminum itself is a comparatively inexpensive metal that is also relatively lightweight. The low weight ensures shipping costs remain as low as possible. The biggest drawback of aluminum is that it corrodes, although aluminum corrosion is white instead of iron's iconic red. The aluminum boilers in entry-level machines will eventually wear out from corrosion. Buyers understand that these machines are made inexpensively and don't expect them to last forever, though. Aluminum's thermal conductivity is serviceable. Even if it's not as ideal as some other metals, the difference in its conductivity and that of other metals doesn't make a noticeable impact on the quality of espresso that these machines produce. However, other features are also built inexpensively, and might not necessarily be optimized for maximum flavor and extraction. Stainless Steel Stainless steel is sometimes used in addition to or instead of aluminum. When it's used with aluminum in an espresso machine's boiler, the stainless steel lines the inside of the boiler — where the metal is in near-constant contact with water. The obvious benefit of stainless steel is that it resists corrosion. The metal can theoretically last indefinitely, extending an espresso machine's life span well beyond what's expected of an entry-level machine. The drawback of using stainless steel in an espresso machine boiler is the corresponding increase in cost, as stainless steel is more expensive than aluminum. Manufacturers most often use stainless steel in mid-tier espresso machines, although it's not necessarily a commonly used option even at this tier. Brass Brass is widely used in espresso machines, ranging from mid-tier machines to high-end ones. Although brass costs more than either aluminum or stainless steel, it provides a large upgrade in performance — and that upgrade is noticeable in the quality of espresso that the machine produces. The thermal conductivity of brass is high, and this provides a demonstrable improvement in the brewing temperature of espresso shots. Maintaining a consistent brewing temperature is essential to consistent extraction through an entire shot. An espresso machine's boiler becomes hot as a machine warms up, and then it transfers some heat to the water in it as the machine pulls an espresso shot. Without heat transfer from the boiler, the water will cool as a shot is pulled because hot water is being taken from the boiler. The cooling results in a declining brew temperature throughout the pull, which alters extraction and flavor. Brass is fairly thermo-conductive, which allows it to quickly transfer heat to water. This is what makes brass suitable for the higher-end espresso machines, as it helps maintain consistent brewing temperatures. Although brass is more expensive than either aluminum or stainless steel, buyers of mid-tier and high-end espresso machines are willing to pay the increased cost in order to get better espresso out of their machine. Copper Cooper is even more thermo-conductive than brass, but it's also more expensive. This makes copper the best-performing of these metals. However, the cost of copper ultimately prevents manufacturers from using it for the boiler of any but the highest-end espresso machines.
