  • 3 Reasons to Choose Galvanized Steel

    Galvanized steel is a corrosion-resistant metal that has a huge variety of uses. Galvanized steel uses a zinc coating over the steel to prevent corrosion and helps the metal stay protected from rust and other corrosive contaminates for many years. There are few drawbacks to this kind of steel, although galvanized metals tend to be more expensive than basic forms of metal. So why should someone use zinc-coated steel over other non-corrosive metals, such as aluminum? Galvanized products actually provide many benefits over weaker, non-coated metals that make them the...

  • The Advantages and Disadvantages of Galvanized Steel

    As life continues to become increasingly complex, the methods we use to create products must also improve. Gone are the days where many were content in simple, small homes, brick roads and buildings that were only a few floors tall. Now, we find ourselves in an age where everything is complex, with the mansion sized homes, bridges stretching over rough rivers and buildings reaching up into the clouds. With progress such as this, simple wood and brick building methods can no longer cut it. So we have turned to strong...

Industry Information

Galvanized Steel

Galvanized steel articles are coated with one or more layers of zinc in order to improve strength and corrosion resistance in industrial, commercial and domestic applications where steel parts are exposed to corrosive materials or are in high use.

Steel, composed predominantly of iron, is among the most common alloys in the world. In addition to iron and carbon, other metallic elements are introduced to create unique alloys with application-specific properties. Galvanization enhances these qualities by forming a metallurgical bond between the steel and zinc. This not only improves tensile strength but also provides an added layer of protection. While this layer, varying in thickness from one mil to just over four mils, will eventually corrode, the damage is significantly slowed. The application of zinc is a relatively simple and cost effective procedure, making its use popular for a variety of steel hardware and fixtures such as grills, grids, grip plates and grates, nails, braces, screws, beams, studs and even automotive paneling. A wide variety of industries make use of the prolonged lifespan of galvanized steel parts. Construction, automotive, electronic, shipbuilding, aerospace, marine, chemical and food processing, power generation, water treatment and several other applications utilize galvanization to ensure the quality and safety of finished products.

Galvanization is most often achieved through a process known as hot-dip galvanizing. Essentially, this involves bathing steel components in molten zinc. Zinc is kept liquefied at temperatures near 860°F. The metal articles, first cleaned with a light acid solution, are either dipped or fed into the zinc bath, which forms a permanent bond with the substrate materials. When exposed to oxygen and carbon dioxide in the atmosphere, the zinc is cured and forms a layer of zinc carbonate that further protects the steel products. While traditional hot-dipping is still widely used, two additional techniques are growing in use and popularity. Electro-galvanizing passes an electric current through the zinc compound in order to create a thinner and more tightly bonded coating. The newest development is the environmentally-friendly thermal diffusion galvanizing, which eliminates the hazardous caustic and acid baths used in traditional methods. Rather than a molten bath, zinc powder is applied to steel parts that are then sealed in a drum and processed through a rotary oven. Zinc can be applied in single or multiple layers depending upon the steel’s intended use. Each technique results in spangle, either uniform or large grain, on the finished product. Spangle is the appearance of a crystalline structure that gives the formerly shiny metals a dull grey appearance. Galvanization is most often applied to pre-formed ready-for-assembly parts, though some steel service centers provide stock shapes as well.
