AGA Honors Excellence in Galvanizing
From the artistic to the practical, a wide variety of projects have been recognized for their creative and innovative uses of hot-dip galvanized coating.
The American Galvanizers Association announced the winners of its 2016 Excellence in Hot-Dip Galvanizing Awards in a statement issued Wednesday (April 6).
According to AGA, more than 120 projects were submitted, representing the versatility of hot-dip galvanizing. All submissions were judged online by a panel of architects and engineers, who selected the 16 award winners.
Bridge and Transportation Projects
101 Freeway Overcrossing | Los Angeles
Category: Duplex Systems
Galvanizer: Valmont Coatings – Calwest Galvanizing
Using a dual protection system, the Los Angeles 101 Freeway Overcrossing, which connects the city’s historic district to the financial and civic districts on the other side of the 101, secured the top spot in Duplex Systems category.
The city reportedly wanted the overcrossing to have a spangled, metallic finish, but the galvanizers explained the chemistry of the steel would dictate the coating finish and would change over time as the zinc coating weathered.
However, not wanting to be deterred from the original vision, the city took an innovative approach and opted to have the spangle pattern painted onto the surface using a detailed stencil. Now, the arc-canopy pedestrian crossing is not only functional, but also an enhancement to the landscape.
Indian Mill Bridge Rehab | Wyandot County, OH
Category: Bridge & Highway
Galvanizer: V&S Columbus Galvanizing LLC
One of two winning projects that featured the rehabilitation of older bridges, the 1861-built Indian Mill Bridge used hot-dip galvanizing in a more pragmatic, utilitarian way.
This single-lane vehicular steel truss bridge, which provides access to the Indian Mill in Wyandot County, had stood for more than 100 years before local community leaders deemed it functionally obsolete and in desperate need of repair in 2010.
As a result, in 2015, the local galvanizer and bridge manufacturer helped restore the bridge, even reusing some of the original 100-year-old steel, to ensure access to this historic site.
The Rehabilitation of the Longfellow Bridge (Phase 1) | Boston
Category: Bridge & Highway
Galvanizer: Duncan Galvanizing Corp.
Although very different from the Indian Mill Bridge Rehab, the $270 million, multi-year Rehabilitation of the Longfellow Bridge (Phase 1) also secured a win in the Bridge & Highway category.
The Longfellow is a combination railway and highway bridge, and is said to be one of the busiest in the commonwealth connecting Boston to Cambridge. The bridge has been on the National Register of Historic places since 1976, so the project required special consideration to safely repair the bridge while maintaining its historical integrity.
One aspect of the project included removing the existing steel arch ribs, galvanizing them, and reinstalling them. The hot-dip galvanizing, along with some duplex-coated parts, is expected to help the iconic bridge resist corrosion for decades to come.
MDX 836 ORT | Miami Dade, FL
Galvanizer: Valmont Coatings – Miami Galvanizing
AGA describes its Transportation category winner as a pragmatic infrastructure element that also mixes in some aesthetic appeal.
The MDX 836 ORT is an open road tolling system, which collects tolls via license plates or radio-frequency transponders so vehicles do not have to stop. Although the toll structure was built for functionality, the MDX authority saw the value in designing it as a gateway to the Caribbean and Latin American culture of Miami.
The structure’s 85-foot wing gantry, which utilizes hot-dip galvanized steel to resist the salty, humid Miami air, is lit up with different colors intermittently to welcome visitors and commuters to the lively city.
NASCAR SAFER Barriers | Kansas City, KS
Galvanizer: Valmont Coatings – Birmingham Galvanizing; Valmont Coatings – Columbia Galvanizing
The Original Equipment Manufacturing (OEM) winner is one of two projects considered by AGA to have demonstrated innovations in the use of galvanized steel in safety structures.
The NASCAR SAFER Barriers were designed to lessen the chance of injury and reduce vehicle damage by distributing the impact load to energy-absorbing foam cartridges. First installed in Indianapolis in 2002, their performance since has led to installation in critical areas of NASCAR and INDYCAR tracks throughout the U.S.
Because the barrier systems are constantly exposed to the elements, it was considered critical to protect the steel panels and components to ensure proper functionality. As a result, the barrier systems utilize hot-dip galvanized steel and some duplex coatings for branding to ensure the important safety features remain race-ready for generations.
Navy Security Fence and Gates | Norfolk
Category: Water & Marine
Galvanizer: V&S Taunton Galvanzing LLC
Another project described as showing innovations in the use of galvanized steel in safety structures took the Water & Marine Award. The Navy Security Fence and Gates are employed for safety by the United States Navy.
The modular structures are used to create a floating fence in order to keep unwanted sea vessels from penetrating inland ports. Because the floating fences are submerged in saltwater and moved around, it was considered important to specify a durable protection coating.
Hot-dip galvanized steel was said to be tested on a few of these innovative safety structures within the past several years, and their performance reinforced the Navy’s decision that hot-dip galvanizing was the correct choice to help protect these structures, and in turn, the nation’s troops.
Energy and Industrial Projects
AEP Bold Transmission | Fort Wayne Area, IN
Category: Electrical, Utility & Communication
Galvanizer: Valmont Coatings – Oklahoma Galvanizing
The AEP Bold Transmission structures also stood out to the panel as a project that showed innovation in the use of galvanized steel and are described as a revolutionary, high-efficiency solution to the power transmission and distribution market.
According to AGA, the high-capacity, efficient galvanized steel structures boost capacity with a lower profile, eye-pleasing crescent-shaped cross-arm design. These innovative poles marry form and function, delivering more power while using less right-of-way.
Iowa Fertilizer Company (IFCo) | Wever, IA
Galvanizer: AZZ Galvanizing – Dixon, Kansas City, Peoria, St. Louis and Winsted
Both Industrial category winners are said to demonstrate durability and ingenuity.
AGA said the Iowa Fertilizer Company (IFCo) utilized hot-dip galvanizing because of its proven track record in the petrochemical industry and its ability to withstand the corrosiveness and abrasiveness of the environment. In addition to the durability in an aggressive environment, hot-dip galvanizing offered cost effectiveness, expedited delivery and long-term corrosion control.
Irving Pulp & Paper Plant | Saint John, New Brunswick
Galvanizer: Corbec Inc. – Montreal; Corbec Inc. – Quebec City
The Irving Pulp & Paper Plant also won in the Industrial category for its use of hot-dip galvanizing for its tough, long-lasting protection of steel.
Although originally slated to be painted, once the specifiers understood the initial cost of hot-dip galvanizing was competitive with the high-performance paint system, the specification was converted, AGA explained.
Hot-dip galvanized steel was said to have added substantial value to the project because of its long life and ultra-low maintenance. Even in the aggressive, corrosive environment of a pulp and paper mill, galvanized steel is expected to deliver maintenance-free longevity for decades to come.
Pyramid Residential Building | New York
Category: Most Distinguished
Galvanizer: V&S Amboy Galvanizing LLC; V&S Lebanon Galvanizng LLC
The highest honor, designated Most Distinguished, was given to New York’s Pyramid Residential Building designed by architects at Bjarke Ingels Group (BIG). The project used hot-dip galvanized steel for the frame of the 467-foot pyramid, not only for its maintenance-free longevity but also to create a structure that stands out in a city with so many other iconic structures.
Marketplace Center | Boston
Category: Lifetime Achievement Award
Galvanizer: Duncan Galvanizing Corp.
The Lifetime Achievement Award recognizes galvanized projects with at least 15 years of service and are also featured in the AGA’s Galvanized Steel Studies (GSS). The Marketplace Center was redeveloped in the late 1960s, and the “Walkway to the Sea” was constructed in 1985 utilizing a duplex system of hot-dip galvanizing and paint. The steel framed, glass-canopied structure was designed to allow pedestrians to walk directly to the waterfront, and the duplex system provides both aesthetics and corrosion protection to the structure.
Rounding Out the Field
The following projects were also recognized for their excellence in additional award categories.
Mammoth | San Jose, CA
Galvanizer: Valmont Coatings – Calwest
This galvanized bent-pipe sculpture depicts an enormous adult mammoth standing over 12 feet tall and 18 feet long weighing in at a massive five tons.
Scott Family Amazeum | Bentonville, AR
Category: Building & Architecture
Galvanizer: AZZ Galvanizing, Arkansas
This project truly displays the combination of fun and functionality that HDG provides, AGA said, adding that the Scott family wanted an eco-friendly, green facility that could endure not only the outdoor elements but also constant use from thousands of children.
Rolland Beaudin Outdoor Stage | Quebec City
Category: Recreation & Entertainment
Galvanizer: Corbec Inc. – Quebec City
This project, designed to provide visual impact while protecting entertainers and equipment in the outdoor park, suggests a bird taking flight. The curved “wings” and frame of the structure were hot-dip galvanized to provide durable, long-lasting corrosion resistance.
Agromillora Florida Greenhouse Project | Wildwood, FL
Category: Food & Agriculture
Galvanizer: Valmont Coatings – Tampa Galvanizing
The very nature of a greenhouse is to develop a warm, humid environment which is extremely detrimental to steel structures. Hot-dip galvanizing will ensure the steel structures have the corrosion protection necessary to continue important work in a difficult environment.
Natalee Lee Quay Lemur Lotus Tower | Myakka City, FL
Category: Civic Contribution
Galvanizer: Valmont Coatings – Tampa Galvanizing
The Lemur Conservation Foundation (LCF) wanted an observation tower on the Myakka City Lemur Reserve to be functional, aesthetically pleasing and artistic. In support of the LCF, many hours of design, engineering fabrication, galvanizing, and installation were done free of charge or at a reduced rate as additional contributions. The need for maintenance to this structure due to corrosion will be minimal, so the animals and facilities will not need to be disturbed.
The Excellence in Hot-Dip Galvanizing Awards seek to recognize the special skill and efforts of galvanizers, fabricators, architects, engineers, contractors and all other parties as they complete projects that will remain durable, beautiful and maintenance-free for generations to come.
All of the projects submitted to the 2016 competition will be added to the Case Studies section of the AGA Project Gallery.
