Why Galvanized Fencing is Important - The Red Brand Post

Wood fences can rot. Stone fences can crack. And wire fences? They can rust. At Red Brand, we regard fencing as an investment. You work hard to assure your animals&#; safety. To protect what&#;s important to you, we manufacture our fences to stand strong against all types of weather conditions. However, even a light rainfall can harm steel at the atomic level. Due to oxygen molecules that produce iron oxide, rust will appear on exposed steel. That&#;s why all Red Brand fence features galvanization for lasting performance.

What is Galvanization?

Galvanization is the process of coating metals like steel and iron with zinc. The mineral acts as a barrier from factors like humidity, salt air, pollution, chemicals, dust and other abrasive air qualities.

All Red Brand fence is galvanized using a process known as the &#;hot dip&#; method. The steel wire is immersed in a bath of molten zinc where a reaction occurs creating a uniform coating around the wire. As a result, a layer of bright, shiny zinc remains on the surface of the steel. Since the wire will inevitably scratch in the field, this zinc coating will be the first line of defense. The galvanized surface sacrifices itself to prevent moisture and corrosive elements from reaching the steel.

Which Class of Galvanization Should I Use?

Fence life is determined by several factors. Weather conditions, air quality, proper installation techniques, and of course, the amount of zinc coating all contribute to longevity. No two farms are alike, and no two fence needs are alike. Therefore, we offer three different classes of galvanization depending on what will best suit your needs. Each class is associated with a minimum coating weight per square foot of wire.

Red Brand products conform to ASTM standards for coating weights to assure quality. The Commercial Class of galvanization contains the smallest amount of zinc. It provides the most affordable fence coating possible. However, there is no minimum ASTM requirement for Commercial (Regular) galvanization.

Red Brand &#;Tradition&#; fence products utilize a Class 1 coating of zinc. The minimum coating thickness of Class 1 is .28 ounces per square foot. Class 1 is suitable for most farm applications.

For properties that are especially prone to rust, &#;Extended Life&#; fence is coated with our heaviest layer of zinc. As a result, Class 3 service life is 2.5 times longer than Class 1 coating.

The majority of Red Brand&#;s woven fence styles are available in either Class 1 or Class 3 coatings of zinc. Stockade panels, poultry netting, and other welded wire fences are primarily available in Commercial grade. Here&#;s a video that further explains our product line-up.

The Effects of Rust

Remember that all wire fences will eventually succumb to rust. Fortunately, galvanization slows the process down considerably. Rust doesn&#;t necessarily mean fence failure. Fences with some rust are more than adequate in most circumstances. How long a fence lasts depends on the conditions of its use and the amount of galvanization. When properly installed, Red Brand fence should last 20-30 years. In some instances, Red Brand fence has lasted up to 50-60 years. A good investment, indeed!

Be sure to talk with your local Red Brand dealer to determine which class of galvanization is best for your application.

Uses of Aluminum

Aluminum is a versatile and widely used metal in manufacturing. For example, in the transportation sector, aluminum is extensively used in the manufacturing of cars, trucks, airplanes, trains, and even ships. It is used in engine components, body panels, wheels (alloyed with magnesium), and frames. Aluminum is also commonly utilized in the construction industry. Its corrosion resistance, strength, and durability make it a popular choice for building structures, including roofs, windows, doors, and facades.

Examples of Aluminum Parts and Applications

Aluminum has extensive application across various industries. Some examples of aluminum parts are listed below:

1. Extruded aluminum alloys are used for window and door framing. 
2. Deep-drawn aluminum sheets allow beverage and aerosol cans to be made cost-effectively. 
3. Long-distance and high-voltage conductors rely on aluminum as it has a considerably lower cost than copper for almost the same performance. 
4. Apple and other computer manufacturers use die cast and machined aluminum for PC bodies as it is lightweight and durable.

Advantages and Disadvantages of Aluminum

Aluminum offers a range of advantages that contribute to its widespread use in most areas of product and human environments. These are:

1. Has a low density compared to many other metals, making it an excellent choice for applications in which weight affects performance or efficiency, such as in transportation. 
2. Has a natural ability to resist corrosion. When exposed to air, it forms an impervious and robust oxide layer on its surface, which acts as a protective barrier against further corrosion.
3. Is an excellent conductor of heat and electricity. It has approximately 60% of the electrical conductivity and 50% of the thermal conductivity of copper, at a fraction of the raw material cost.
4. Aluminum alloys have a higher strength-to-weight ratio than steel, making them suitable for a range of structural applications. The material also retains its ductility in heavy use, allowing for structures that are failure-resistant.
5. These alloys offer great ductility and malleability, with moderate weldability, allowing their use in a wide range of manufacturing processes.
6. Is highly recyclable, and its recycling process requires significantly less energy compared to the production of primary aluminum.

Aluminum also has application and performance disadvantages that must be accounted for:

1. Is more expensive than steel, its primary material alternative, for several reasons. The high cost of bauxite processing (in terms of energy required to produce aluminum from ore) can limit the economic practicality of its selection.
2. Its thermal conductivity can be a disadvantage in certain applications, as can its higher coefficient of thermal expansion than steel. Temperature distortion and unwanted thermal transfer in building systems can be significant issues that must be handled with careful design.
3. Exposure to sudden temperature changes or extremely high temperatures can cause the metal to become brittle, losing structural strength and durability. Aluminum engine blocks have been known to fail due to designs that failed to compensate for or prevent damaging temperature fluctuations.
4. Has a relatively low melting point compared to other metals, such as steel or copper. This is a disadvantage in all high-temperature applications.
5. Although aluminum is more corrosion-resistant than many other metals, it can still corrode in some environments, requiring: good design, effective maintenance, and protection in certain applications, such as those exposed to seawater.

Applications of Galvanized Steel and Aluminum

Many applications can be made from either galvanized steel or aluminum, and both metals have specific properties that make them suitable for certain uses. Galvanized steel is a popular choice for applications that require a durable, rust-resistant material. For example, it is commonly used in the construction of automobiles, roofing, and fences. Walkways and stair surfaces are commonly made from aluminum or galvanized steel treadplate, each of which has particular application advantages.

Aluminum benefits from having a low density and high strength-to-weight ratio, making it particularly useful in transportation industries for structures such as aircraft, some ships, and railway cars. Low weight can benefit the making of building components, electrical equipment, and cooking utensils.

Both galvanized steel and aluminum are used extensively in the manufacturing of fan blades. Galvanized aluminum sheet materials are more specifically used in this application due to their lightweight property. However, most HVAC (heating, ventilation, and air conditioning) ducting and fan enclosures are made in galvanized steel sheets for their low cost of materials and high processability.

Choosing Between Galvanized Steel and Aluminum

Choosing between galvanized steel and aluminum depends on various factors such as the application, budget constraints, and environmental considerations.

Material selection must align with a project's primary and secondary requirements, considering factors like strength, corrosion resistance, weight, budget, and aesthetics. Careful design to compensate for a material's weaknesses or better exploit its strengths can alter the material selection in ways that allow better cost or performance.

Galvanized steel outperforms aluminum in strength and durability, making it ideal for applications that require a tougher and more durable material, such as structural components, fences, and outdoor equipment.

Aluminum, on the other hand, is lighter weight but less strong than equivalent sections/gauges of steel but has a higher strength-to-weight ratio. It is more suitable for projects in which weight is a primary driver, like aerospace or transportation, but may not be as robust in heavy-duty applications.

Malleability

Aluminum has a high malleability, which means it can be easily bent, shaped, or formed into various configurations without losing its structural integrity. Galvanized steel is also malleable to a certain extent, but less so than aluminum.

For applications that require extensive shaping, forming, or intricate designs, aluminum is often the easier-to-process choice. However, extreme forming of steel can be performed hot, allowing for increased complexity of shape as a consequence of accepting the increased complexity of the process.

Price

The cost of galvanized steel and aluminum varies widely depending on various factors, including the type, form, thickness, size, and market conditions.

The cost of galvanized steel can range from $0.50 to $1.50 per pound, depending on the specific grade and form. Aluminum prices can range from $1.50 to $3.00 or more per pound for common aluminum alloys, influenced by grade, form, and market conditions.

For accurate pricing information, it's necessary to contact metal suppliers to get an accurate application/volume-specific price for your needs.

Durablility

The relative durability of galvanized steel and aluminum depends heavily on the application and environmental factors.

Galvanized steel is renowned for its durability, particularly in outdoor and (mildly) corrosive environments. It is often used in applications in which long-term durability is a key driver. However, galvanized steel will corrode if the zinc coating is compromised or if it is exposed to unsuitable conditions. Overall, galvanized steel benefits from the properties of steel&#;toughness, ductility, high tensile strength, low fatigue rates, and hardness&#;with the zinc coating compensating for the high environmental susceptibility.

Aluminum is naturally corrosion-resistant due to the formation of a self-healing protective oxide layer on its surface, making it moderately damage-tolerant in terms of corrosion resilience. Aluminum is lightweight making it a suitable choice for applications in which weight and corrosion resistance are essential, such as in aerospace, marine, and outdoor applications. However, it may not be as strong or durable as galvanized steel in some heavy-duty or high-impact applications. In particular, aluminum is more susceptible to fatigue failures and can become embrittled by stress and temperature fluctuations.

Galvanized steel is generally more rust-resistant than aluminum in most non-aggressive environments. The zinc coating on galvanized steel serves as a sacrificial barrier. When it gets scratched or damaged, the surrounding zinc corrodes before the underlying steel, providing a measure of ongoing protection.

Aluminum naturally forms a thin oxide layer on its surface, which protects it from corrosion. While aluminum is highly corrosion-resistant and does not rust in the same way that steel does, it can still corrode in certain specific environments, such as highly acidic or alkaline conditions and in places where mineral deposits can collect.

In typical outdoor environments, in which exposure to moisture is common, galvanized steel's rust resistance tends to be superior to the resistance of aluminum to corrosion, but both will perform well and survive long term. The cost then drives the selection of galvanized steel for applications like fencing, structural components, and outdoor equipment.

In marine environments, aluminum offers some benefit in corrosion performance over galvanized steel, as long-term salt exposure will affect steel considerably more than the self-healing oxide barrier on aluminum, once the zinc begins to erode.
