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.
The facility features large-capacity kettles for hot-dip galvanizing, fully automated plating lines, and an experienced team focused on consistency, speed, and quality. These capabilities allow the operation to handle everything from structural steel and large assemblies to small parts and high-volume plating runs.
With advanced process control and automated systems, the Milwaukee location ensures tight tolerances and repeatable results across both galvanizing and plating applications. Zinc, nickel, and specialty finishes are processed efficiently, while integrated material flow and racking systems keep turnaround times fast. This combination of technology and expertise makes it possible to serve a wide range of industries with complex project needs and demanding timelines.
Strategically located in the Upper Midwest, the facility plays a critical role in AZZ’s North American network. Customers benefit from local support backed by the strength of a national operation, gaining access to trusted metal finishing solutions that stand up to the harshest environments.

We’re proud to announce that AZZ earned five awards at this year’s Annual Conference:
🏆 Bridge & Highway – “FARM Bridge Program Project” AZZ Galvanizing – St. Louis The FARM (Feasible, Accelerated, Resilient, and Modular) Bridge Program is transforming rural infrastructure by streamlining the delivery of small-scale bridges using modular construction techniques. This award-winning project exemplifies the program’s mission to deliver cost-effective, quickly deployable, and long-lasting solutions for underserved communities.
🏆 Electrical Utility & Communication – “Modular On-Grade Bull Towers” AZZ Galvanizing – Chelsea Fabricated for modular deployment on remote sites, these on-grade “Bull Towers” offer essential support for electrical and communications networks. Hot-dip galvanizing was chosen for its proven resilience in extreme outdoor environments and for its ability to meet stringent service-life expectations.
🏆 Recreation & Entertainment – “Bucktown Bird’s Nest Learning Pavilion” AZZ Galvanizing – Baton Rouge Perched along the scenic shoreline of Metairie, Louisiana, the Bird’s Nest Pavilion is a sculptural blend of nature and engineering. Designed as a space for community gathering and learning, its galvanized frame, handrails, and staircase provide lasting strength and corrosion resistance in a demanding coastal environment.
🏆 Water & Marine – “Candle Lake Control Structure Upgrades” AZZ Galvanizing – Saskatoon Located near a popular campground in northern Saskatchewan, the Candle Lake Control Structure manages water levels and flow into the Torch River. Originally built in 1977, the structure was upgraded for improved safety, functionality, and resilience. Hot-dip galvanizing was selected for all steel components, including platforms, stairs, and hoist structures, offering long-term corrosion protection in a high-use, weather-exposed environment.
🏆 Lifetime Achievement Award – “Harley Davidson Museum” AZZ Galvanizing – Joliet, AZZ Galvanizing – Dixon A lasting symbol of American craftsmanship, the Harley Davidson Museum stands as a testament to the power of preservation through galvanizing. Since its construction in 2008, the museum’s exposed steel components have withstood the elements with virtually no need for maintenance, earning it this prestigious recognition.
The durability of the smallest components can be critical to a structure’s integrity and performance. These small components often have intricate designs requiring that a protective coating does not interfere with surface integrity.
Spin galvanizing is a hot-dip process which 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 fits, and precise functionality.
The spin 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.
Here are just a few reasons to protect your small components with AZZ’s Spin Process:
1 – 100% Complete and Consistent Coverage
Our high quality spin process guarantees even coating for secure connections and lasting fits, while ensuring the visibility of required identification and specification information engraved or stamped in the steel.
2 – Coating Thickness
Depending upon diameter, parts will receive from 1.7 to 3.4 (43 to 86 microns) mils of the impervious zinc coating. Zinc-plated components have a thin zinc coating, up to only 1 mil (25 microns).
3 – Bond Strength
Resulting bond strength nears 3600 psi (24.82 MPa). The coating is extremely difficult to damage. Painted and zinc plated coatings have a typical bond strength of only a few hundred PSI and are easily scratched and removed.
4 – Hardness
Spun parts have zinc-iron alloy layers, formed during the galvanizing process, that are harder than the base steel itself. These abrasion resistant layers make the galvanized coating difficult to damage during tightening.
5 – Paintable
Prepared according to ASTM D 6386 (Practice for Preparation of Zinc [Hot-Dip] Galvanized Coated Iron and Steel Product and Hardware Surfaces for Painting), hot-dip coatings are successfully painted, providing long-lasting under film corrosion protection.
