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.
Battling Corrosion in the Southeast: The Power of Hot-Dip Galvanizing
The southeastern United States, with its picturesque coastal landscapes and vibrant industrial hubs, faces a unique challenge: corrosion. The region's high humidity, frequent rainfall, and proximity to the ocean make it a prime breeding ground for rust and deterioration. However, there is a formidable solution that has proven its mettle time and time again – hot-dip galvanizing.
The southeastern United States, with its picturesque coastal landscapes and vibrant industrial hubs, faces a unique challenge: corrosion. The region’s high humidity, frequent rainfall, and proximity to the ocean make it a prime breeding ground for rust and deterioration. However, there is a formidable solution that has proven its mettle time and time again – hot-dip galvanizing.
By immersing metal in molten zinc, hot-dip galvanizing creates a protective barrier that shields against the corrosive forces of the Southeast’s environment.
Hot-Dip Galvanizing: The Ultimate Corrosion Barrier
Hot-dip galvanizing provides unmatched corrosion resistance, making it an ideal choice for the Southeast. The zinc coating acts as a sacrificial barrier, corroding preferentially to the underlying metal. This sacrificial protection ensures the preservation of structures and equipment by shielding them from the damaging effects of rust and deterioration.
Ideal for Coastal and High-Humidity Environments
The Southeast’s coastal areas and high humidity levels make hot-dip galvanizing even more crucial. It protects against saltwater exposure, humidity, and airborne pollutants. The zinc coating’s resilience in harsh coastal conditions and high humidity environments ensures the longevity and durability of structures, bridges, marine applications, and offshore installations.
Cost-Effective and Sustainable
Hot-dip galvanizing not only prevents corrosion but also offers long-term cost savings. Structures and equipment that undergo galvanizing require minimal maintenance, reducing the need for frequent inspections, repairs, and repainting. Additionally, the recyclability of zinc aligns with sustainable practices, reducing the environmental impact and contributing to a more sustainable future.
Hot-dip galvanizing is the go-to solution for preventing corrosion in the Southeastern United States. Its unmatched corrosion resistance, ability to withstand coastal environments and high humidity, and long-term cost savings make it an essential protective measure for metal structures and equipment. By choosing hot-dip galvanizing, businesses and infrastructure projects can ensure the longevity, safety, and sustainability of their assets in the face of corrosion.
