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.
Your Help Is Needed Now! Nineteen AZZ Employees Need Assistance
It’s been nearly three weeks since Tropical Storm Imelda flooded Beaumont, Texas, but the devastating aftermath is still being felt by 19 plant workers at AZZ Galvanizing – Beaumont.
Many AZZ employees lost homes, cars, and even simple necessities, such as clothing and mattresses during the worst flooding since Hurricane Harvey. In light of this recent flooding, the AZZ Cares Foundation is seeking donations for the employees who are in urgent need of assistance.
As an example of just one of the 19 plant workers who is requesting assistance, Ricky Harper, a production worker for AZZ Galvanizing – Beaumont, lost his car in the floodwaters while trying to take his wife, Stacey, to her monthly cancer treatment at MD Anderson in Houston. Hours later, the couple had to grapple with another loss – their home, which was in ruins because of the catastrophic flooding.
“Taking care of my wife and being blessed with a job is what keeps me going through hard times like this, said Ricky. “I’m the one who takes care of her, so I have to keep going no matter what.”
Please help all the AZZ employees impacted by the storm, and that have requested assistance, by donating today at: https://www.azzcaresfoundation.org/Beaumont. The AZZ Cares Foundation is supported 100 percent by generous donors like you, and is currently behind in reaching its yearly donation goal. To continue providing assistance to those in need, we urgently need your help. Please go online and donate today. Your donation is tax deductible, and 100% of all donations received go directly to those in need of assistance.
For more information about the Foundation’s mission, past successes, and to join our reoccurring donor program, please visit azzcaresfoundation.org.
Thank you for your continuing support and consideration,
