AZZ Metal Coatings Set to Exhibit at Fastener Expo 2022

Galvanizing, Metal Coatings

Each year, thousands of attendees from 30+ countries travel to North America’s #1 trade show city, Las Vegas, Nevada to network and do business with hundreds of suppliers showcasing every type of fastener for several industries including construction, aerospace, military, electrical, and automotive. Electronic fasteners, specialty tooling products, special application fasteners, tooling and machinery, hand tools, power tools, service solutions, and much more will be on display. This is the trade show where all types of distributors come to network and see customers, build new relationships, and find new products. 

AZZ Metal Coatings (booth 1823) will be on-hand to showcase its capabilities as a leading provider of spin galvanizing services. Spin galvanizing is a hot-dip process that utilizes a centrifuge anchored to a galvanizing kettle (or a spinner located above it) for immersing small to medium scale components in molten zinc.  A tightly bonded alloy coating forms on the steel, providing long-term, durable protection from the devastating effects of corrosion, while the centrifuge or spinner removes excess molten zinc to ensure coating uniformity, quality fit, and precise functionality.

The spin galvanizing process, combined with AZZ’s automated conveyor lines, are used for a wide range of small to medium-sized components including all thread rods, nut blanks, guardrail bolts, anchor bolts, washers, turnbuckles, and wheels.  The process provides high-performance corrosion protection and a consistent uniform coating.

Plan to join AZZ on October 17th-19th, 2022 at the Mandalay Bay Convention Center in Las Vegas. For more information, visit: https://fastenershows.com/

Galvanizing

Nestled in the plains of Kansas lies the Kansas Children’s Discovery Center, a place where its core mission is to enhance the lives of children and enrich the communities they serve. So, when the University of Kansas’ School of Architecture and Design was approached to help build a canopy for the Center, the students jumped at the chance to get hands on experience while giving the current and future generations of children to enjoy.

The Center was looking for a canopy that was sturdy and would blend in with the surrounding structures on site. They also asked for a piece that would capture the attention of the children while providing a safe shelter to allow kids to enjoy the scenery outside. The KU students decided to use HSS material mix along with support tubes running across the top that is finished off by repurposed sheet steel for cover.

With a plan in place, the students began putting together ideas on how to build the strong structural shape that would hold up to the outdoor elements. From there, hot-dip galvanizing became a strong candidate for their needs. KU approached the galvanizer with this project in hopes to accomplish their goal of providing a long-lasting solution to the children that visit the Discovery Center daily.

By going with hot-dip galvanizing, this ensured that corrosion would be a non-factor for both inside and outside the hollow structures. In the end, the job produced more than just a canopy – it provided everyone involved an opportunity to give back to the local community in which we serve.

Extreme hailstorms are occurring with both more intensity and frequency than just a couple decades ago. While scientists debate why these storms are different today, no one argues with their catastrophic effects.

The damage from a hailstorm can be devastating to any residential and business properties in its path. The United States experienced that largest single insured loss event in May of 2014 when a system of severe storms rained hail sporadically over a 5-day stretch causing heavy and damage and destruction from Colorado to Pennsylvania with insured losses exceeding $2.9 billion.

Colorado’s most damaging hailstorms generally occur between mid-April to mid-September, with the Front Range located in the heart of what’s now called “Hail Alley”. Colorado residents and businesses can count on three or four catastrophic (defined as at least $25 million in insured damage) hailstorms every year. The past 10 years have been brutal for Colorado, eclipsing more than $5 billion in losses, and that’s just the insured damage.

Few businesses have more exposure to these storms than new car dealerships, with car and truck inventories values into the tens of millions sitting exposed in the parking lot. A major dealership can lose a large percentage of the inventory in just a single storm. In some cases, these late model cars can incur damage that’s beyond the value of the vehicle. It’s not uncommon the numbers of damaged cars and trucks exceeds the available resources for timely repairs, leaving the decision makers with few options beyond liquidation of the damaged vehicles at a fraction of the original value.

Insurance companies have taken notice and believe this new breed of hailstorms is here for the future. Some insurers are refusing to cover dealerships (especially along the Front Range) due to the increased odds for hail damage. Others are charging rates several times higher than just a few years ago. This has left the dealerships with few avenues beyond paying these exorbitant rates while waiting to see which company will be unlucky enough to experience that aftermath of the next big storm.

Schomp Automotive Group decided on a different course of action. Rather than just waiting and watching the skies, the designers at Schomp Automotive Group began to develop a system to mitigate the hailstorm threat. In 2021, Shomp began to construct a hail-net system called “Hail No” to protect their exposed car inventory. This creative design uses large 10″ and 12″ diameter steel tube columns set in concrete to support a strong netting system with spans as long as 63′, capable of supporting up to a foot of snow. The netting system is designed to be easily taken down and stored for the winter months when snowstorms can occasionally exceed the “Hail No” system load capacity.

The hot-dip galvanizing coating was selected for its sustainability and much smaller carbon footprint than any of the other protective coating options, which would require periodic maintenance or recoating intervals every five to fifteen years. Hot-dip galvanizing has a proven track record for providing decades of maintenance free protection from corrosion. These more destructive hailstorms will be no match for the hot-dipped galvanized steel columns. The zinc and iron alloy layers that form on the steel during the galvanizing process are harder than the base metal it covers, thus providing added strength and additional protection from impact damage that would compromise other protective coatings.

Another important consideration was the fact that the hot-dip galvanizing process coats all surfaces internal and external, providing equal protection on the inside of these hollow columns. The internal galvanizing coating ensures that there are no opportunities for unseen, internal corrosion to set in. The Hail No protection system was truly designed to last a lifetime and beyond.

Insurance companies are buying in with the new “Hail No” system by lowering insurance rates as much as 40-50 percent for the vehicles protected by the new netting system. That’s enough saving to pay for the system within just a few years. Dealership interest is certainly growing along the Front Rage as well as outside the region with several dealerships making plant to invest in the “Hail No” or similar system to mitigate the hailstorm concern.

Galvanizing, Metal Coatings

The City of Birmingham and the University of Alabama at Birmingham (UAB) have had discussions for 35 years on how to replace Legion Field (UAB’s home field since 1927), which lacks the amenities of modern sports venues and is a maintenance drag because of its age. It took decades for the stadium to take shape, with ideas ranging from an on-campus open-air venue to a domed stadium to attract a professional franchise. Finally, UAB,  along with local governments, the area civic center authority and Birmingham-based Protective Life Corporation designed and built an outdoor stadium in downtown Birmingham.

As part of the Birmingham Jefferson Convention Complex, the 45,000-seat venue will be the new home for the UAB Blazers football team, as well as host the Birmingham Bowl, high school football championships, concerts and The World Games opening and closing ceremonies in 2022.

The $200 million civic infrastructure investment must live up to the hype and be able to preserve its beauty and stature for decades to come. Therefore, the design team called on the reliable corrosion protection system: hot-dip galvanized steel. The fabricator has years of experience with hot-dip galvanized coatings on high profile projects such as the Texas Motor Speedway and Daytona Speedway. In fact, the fabricator’s preference for corrosion protection is a hot-dip galvanized coating due to its maintenance and corrosion-free life expectancy.

The general contractor broke ground in January 2020, just before the world changed. It was imperative to have the stadium completed by October 2nd for the first home game of the UAB 2021 football season. The COVID-19 pandemic nor weather delays could stand in the way of the budgeted completion dates. Fortunately, hot-dip galvanizing can be completed in all-weather situations, 24 hours a day, 7 days a week.

Additionally, hot-dip galvanizing was deemed an essential industry and AZZ did not experience downtime during the pandemic; while the impacts of COVID-19 were being felt in all aspects of work and live, the steel fabrication and hot-dip galvanizing of 400 tons of steel was able to remain on schedule and within the budgeted time of completion.

Protective Stadium is the centerpiece for the new entertainment district of downtown Birmingham, Alabama. The hot-dip galvanized, aesthetically pleasing venue will be highly visible to all downtown visitors, student and tourists, promoting hot-dip galvanizing as the coating preference for all outdoor venues for future generations.

Hot-Dip Galvanizing and Zinc Plating: What’s the Difference?

Hot-Dip Galvanizing and Zinc Plating: What’s the Difference?

Back to Basics — Understanding Both Galvanizing Methods

Generally speaking, galvanizing is the process of applying a thin layer of zinc over a material, typically steel, to protect it from corrosion or rust. This considerably extends the life of the base metal, making it sustainably and economically advantageous when planning your project.

Hot-dip galvanization is named “hot” for a reason. After the raw metal has been cleaned and impurities have been removed, a non-oxidizing flux compound is applied. That’s when the heat and zinc come into play — the metal is immersed in a molten zinc bath at 830 to 870 degrees Fahrenheit. The compounds form a bond, creating a layer of pure zinc on the outer surface of the metal. HDG typically results in a strong, thick coating with a dull finish.

Zinc plating, however, utilizes a different approach: after submerging the metal into an electrolytic solution, an electrically charged anode of pure zinc is placed into the solution. This is where its naming convention of ‘electro’ makes sense — electricity is then used to move electrons from the anode to the cathode, causing the zinc to dissolve and bond to the surface of the metal. This method delivers a thinner coating of protection, but a shiny finish and uniform color.

Advantages of HDG and Zinc Plating

You might be thinking, “HDG has a thicker protection layer; isn’t that the clear preferred choice?” The answer is that it all depends on your project needs. For instance, while HDG is preferred for direct outdoor exposure since it’s almost 10 times thicker, zinc plating is sometimes the preferred choice when the project has a cosmetic appeal. Zinc plating is also a great choice when galvanizing a small, thin part, as zinc plating will often induce less stress on the component.

Regardless of which process you choose, both solutions deter rust and corrosion and extend the life of your project.
