Coil Coating Process

Exit End (Recoiler)

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.

Coil Coating Process

Exit Accumulator

Like the Entry Accumulator, the Exit Accumulator adjusts up and down to store metal while the recoiler is unloading a completed coil.

Coil Coating Process

Top Coat

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.

Coil Coating Process

Prime Coat

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.

Coil Coating Process

Cleaning & Pretreating

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.

Coil Coating Process

Entry Accumulator

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.

Coil Coating Process

Entry End

Uncoiler

Metal coils, up to 60,000 pounds, are received and undergo visual inspection before moving to the uncoiler for unwinding.

Coil Stitch

At this stage, previous and next coil ends are mechanically joined, ensuring continuous feed in the coil coating line.

Long-lasting protection for your investment

AZZ Hot-Dip Galvanizing is one of the most cost-effective ways to prevent corrosion of traditional and renewable structures. Steel aged components treated with a zinc coating last for decades while maintaining their integrity even in the harshest conditions with low maintenance requirements.

As North America’s largest galvanizer of fabricated steel, AZZ Galvanizing is a leading supplier of galvanizing to the renewable market. With over 40 locations throughout the U.S. and Canada, an AZZ Galvanizing facility is close for expedient service.
