Once the metal is cleaned, treated, and painted, the strip is rewound into a coil size prescribed by the customer. From there, the coil is removed from the line and packaged for shipment or additional processing.
After the primer is applied and cured, then the metal strip enters the finish coat station where a topcoat is applied. Topcoats provide color, corrosion resistance, durability, flexibility and any other required physical properties. Like primers, the topcoat is cured using thermal cure ovens.
Oven
Coil coating ovens can range from 130 feet to 160 feet and will cure the coatings in 13 to 20 seconds.
During this stage, the strip enters the prime coat station whereby a primer is applied to the clean and treated metal. After the primer is applied, the metal strip travels through a thermal oven for curing. Primers are used to aid in paint adhesion, improve corrosion performance and enhance aesthetic and functional attributes of the topcoat.
S Wrap Coater
The S wrap coater design allows for primers and paints to be applied to the top and back side of the metal strip simultaneously in one continuous pass.
The cleaning and pretreating section of the coil coating process focuses on preparing the metal for painting. During the cleaning stage, dirt, debris, and oils are removed from the metal strip. From there, the metal enters the pretreatment section and/or a chemical coater whereby chemicals are applied to facilitate paint adhesion and enhance corrosion resistance.
Dried-In-Place
In this stage a chemical that provides enhanced corrosion performance is applied. This treatment can be chrome free if required.
The accumulator is a structure that adjusts up and down to store material, which makes continuous operation of the coil coating process possible. This accumulation will continue to feed the coil coating processes while the entry end has stopped for the stitching process. As much as 750 feet of metal can be collected.
Hot Dip Galvanized ‘Bloom’ Art Piece Wins American Galvanizers Association Award
This glowing bloom of shoots and bulbs recently won the American Galvanizers Association (AGA) Artistic award, and AZZ Galvanizing - Reno played a critical role in the finished project by fabricator Michael Christian of Xian Productions.
Modern art has long been a discipline where materials and substrates are innovative. While galvanized metal is best known for how it’s applied in infrastructure and construction, it’s also known for its ability to serve that innovative purpose with the introduction of “Bloom,” a hot dip galvanized art piece in downtown Reno, Nev.
This glowing bloom of shoots and bulbs recently won the American Galvanizers Association (AGA) Artistic award, and AZZ Galvanizing – Reno played a critical role in the finished project by fabricator Michael Christian of Xian Productions.
About the Piece
The “Bloom” piece consists of four parts, including a bottom base, shoots, stalks and blooms. Oblong pieces of plasma welded together comprise the bottom vase, creating a coarse and bark-like texture.
The shoots in the next part were created using bent quarter-inch wires welded together with a steel ring.
Next, the stalks are round tubes in a variety of lengths to illustrate “growth.” At the top, fabricated wires form the blooms, which have lights inside that can dim and glow throughout the night.
Why the Fabricator Chose Hot-Dip Galvanizing
Christian, the fabricator, selected hot dip galvanizing because of the environment. Reno is a desert city that has its share of extreme weather, including intense heat, heavy rains, and severe cold and snowstorms. The zinc coating from the galvanizing is robust enough to protect the piece from those elements. Zinc actually corrodes 30 times slower than steel!
Christian knew the value of the extended corrosion protection offered by galvanizing, but also wanted a uniform coating. AZZ advised him regarding how the coating would look on different steel surfaces, and, after thorough discussions, he decided to sandblast the entire piece for more consistency in its final coat. In the end, this last step helped deliver the most uniform appearance.
Beyond the aesthetics and erosion protection, galvanizing the installation ensured sustainability and provided a quick turnaround time. The investment in galvanizing was both cost-effective and will reduce the need for expensive maintenance.
The GalvXtra Process
AZZ has a world-class, proprietary hot dip galvanizing process known as GalvXtra. The hot dip process includes prepping and cleaning the surface to ensure it’s a smooth as possible, then submerging the steel parts in a bath of molten zinc, where it remains until it reaches 840° F.
At this temperature, the zinc and steel react, developing a zinc/iron intermetallic layer on all surfaces. After dipping, every piece goes through a thorough inspection.
Project Recap
AZZ focuses on creating a stronger, safer world, evidenced by our focus on protecting infrastructure from corrosion. This project was a unique, artistic way to show the possibilities of galvanizing.
Hot-dip galvanizing is a trusted solution for long-lasting corrosion protection, relied upon for its durability and unmatched performance. This video provides a step-by-step look at the galvanizing process, showcasing how steel is transformed with a protective zinc coating that stands up to the toughest conditions. From surface preparation to the final finish, see how this process ensures strength and longevity for projects of all sizes.
