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.

This fast-paced suburb is home to a rich population of aerospace professionals and was recently selected as the location for two new AAR Corp aircraft maintenance hangars. These matching structures will provide not only a lift to the airport’s functionality but to its overall aesthetic as well. The easiest way to describe these two hangars, completed in December of 2016, is to say they are enormous!
Each of these hangers was designed to serve the largest commercial and military cargo planes in existence. As such, the $40 million project consisted of two 10-story side-by-side structures with large clear spans of over 300’ by 300’. The skeleton of these remarkable structures was comprised of hot-dip galvanized steel. AZZ Galvanizing – Hamilton and AZZ Galvanizing – Joliet were recently recognized by the American Galvanizers Association for Excellence in Hot Dip Galvanizing: Building & Architecture for their work on this exciting project.
While airport structures were traditionally limited to pre-engineered steel buildings, lead project design and construction firm Rubb Building Systems wanted something that would prove durable, cost-effective, and most importantly, extremely flexible. The team knew the hangars would change the landscape of the airport, and wanted to offer Rockport International Airport a unique solution that came with every bell and whistle. The end result is impressive: buildings with ventilation windows, conventional doors, massive clear spans with no center columns, continuous translucent roofing, and a hot-dip galvanized steel truss structure. This metal and translucent skeleton provides longevity, corrosion protection, and more than enough room for the jumbo jets it houses. For this project, the consistent zinc finish of the hot-dip galvanized steel on both interior and exterior steel surfaces was both rugged and reliable.
AZZ Galvanizing – Hamilton and AZZ Galvanizing – Joliet is proud to have helped in the construction of these hangars, and look forward to seeing them used to maintain the country’s largest aircraft, including the Airbus A380 jet.
