What are the Key Coating Types of a Painted Steel Coil?
Painted Steel Coil goes through different procedures to become stable and durable that gives the best performance when used in any kind of industry.
Key coatings are some kind of coatings used during the manufacturing process.
Here are two types of coatings used in the manufacturing process of Painted Steel Coil.
When we talk about the application of liquid paints, it needs to fulfill the elementary requirements for the best application. There are two factors for the excellent performance of this product to give in a corrosive environment.
To give the aesthetic look and durable performance even in the fastest procedure (upto220m/min) and gives it the flawless look.
The temperature of the oven depends on the quality and quantity of the paint used in the manufacturing procedure. Its spending time in the oven is different, it’s almost 6 to 60 seconds depends on the lines.
The substrate temperature is also different and mostly it is between 210^C to 250^C.
Flexibility is provided in a Painted Steel Coil for easy bending without cracking, defect-free product. With the ease of flexibility, it does not lose the adherence of the paint film from it.
For the primer, the thickness of dry film coating is 5 to 35 microns, and it is different for the top coating which is 15 to 200 microns. The thickness of the coating on the Painted Steel Coil tells the quality and the requirement of the final product.
Powder coatings are fundamentally “solid paints” which are melted to form a continuous film for the substrate. The application of the powder coating during the manufacturing procedure is done by the two procedures called electrostatic and tribostatic spray powder coating gun.
These coatings are self-limiting in case the thickness of the powder coating reaches the requirement of Painted Steel Coil. It is the inert coating, after melting, the powder flows out from a continuous paint film in the form of solid paint to give excellent finishing to the product.
These two types of coatings give a different kind of authenticity to Painted Steel Coil. It fulfills the aesthetic need of a required product. These paints contain lacquers that are obtained from trees to give the glossy look to the product. These two kinds of coatings are based on two types, thermosetting and thermoplastic fixative or binder.
What is the Manufacturing and Coating Procedure of a Painted Steel Coil?
There are several methods of manufacturing. Painted Steel Coil is prematurely a steel sheet of high quality, which can be coiled. Among all, the manufacturing process of galvanizing a Painted Steel Coil is on top. Which, makes it best at its performance, and durability.
Because it prevents it from rusting. In the manufacturing procedure, Painted Steel Coil is dipped and pre-coated into the molten pool of zinc or iron for maximum long-lasting protection. Which maintains the temperature of (860 ^F) (460 ^C). The metallurgical bond is created between the product and zinc.
The hot-dipped manufacturing procedure is used for the Painted Steel Coil, is the reason of its durability, stability, formability, long-lasting adhesion of color, corrosion-resistant.
In the procedure of manufacturing zinc and iron coating works as the responsible barrier against the rusting and any kind of inconvenience to the Painted Steel Coil. And the best coating gives the high-quality result of a product.
The major steps of the galvanization hot-dipped procedure as follows;
- The first step is to clean the Painted Steel Coil by dipping it into the degreasing solution.
- After cleaning, it is pickled and dipped into the vat of hot and dilute sulphuric acid.
- The third step is to flux the product into the solution typically used zinc-ammonium chloride
- The fourth step includes the immersion of Painted Steel Coil into the vat of molten zinc after the flux. Here it is galvanized properly.
- In the last step, it has to go through an examining process for its consistency and complete corrosion-resisted coating.
What are the Advantages of Buying a Painted Steel Coil?
Several industries utilize the Painted Steel Coil because of its wide range of advantages, including:
Low Initial Cost
The Painted Steel Coil is ready to use right after it is delivered. In addition, as compared to most other treated steels Painted Steel Coil is a high-quality product at suitable pricing. There is no need for additional changes or preparation of it after buying like painting/coating any change in the surface etc.
It goes through a hot-dipped galvanizing procedure which makes its reliability strong and it can last for 50 years in any kind of environment and 20 years even with severe water exposure. There is not even a little bit of maintenance required.
The high-quality manufacturing procedure of Painted Steel Coil increases its stability and reliability for a longer life span.
The Sacrificial Anode
Painted Steel Coil is protected from any damage caused by any kind of environment. It ensures that if it is by any means little exposed it will remain to be coated by zinc.
The pre-treated coating will prevent it from corroding. And this coating will perfectly be creating sacrificial protection to the damaging areas.
In Painted Steel Coil the addition of zinc coating enhancing its reliability and making it rust-resistant. Normally steel elements are incredibly prone to rust but a Painted Steel Coil used a pre-treated coating of zinc which acts as protecting buffer between the product and any moisture and oxygen. Pre-cleaning is an essential procedure.
What is the Lamination of a Painted Steel Coil and What are the Advantages of Lamination?
The lamination process gives it the final finishing, makes it look aesthetic and corrosion-resistant.
In addition to this, lamination films are used when the high quality of a product is required.
There are four types of films to be used in the lamination of a Painted Steel Coil.
- (PVC) polyvinylchloride
- Polyvinyl fluoride
- Thermoplastic acrylics &
- (PET)Polyethylene terephthalate
There is another process of co-laminating which is the blend of coating and laminating. Where liquid paints or coatings and laminates are mixed with an excellent blend.
First, the primer or any basecoat color is applied of your choice. The clear laminate is used in this mixture for it is excellent abrasion resistance.
There is a vast range of advantages because of these excellent and resilient procedures of a Painted Steel Coil which give it maximum protection in every kind of environment.
The high-quality laminating films make it abrasion-resistant. Painted Steel Coil can survive in acidic and alkaline environments because of these laminations.

There are many methods used to test the quality control of a product. Here are some of the methods:
The viscosity of the paint in a Painted Steel Coil is measure through two different procedures. Measuring the consistency of coating tells the durability of the product. If using polyurethane, PVDF, and epoxy. For measuring the liquid paint is poured into the vessel that has a ting hole into the bottom of the vessel.
The time is measured in which the paint flows from a vessel and makes it empty. The specification of the testing procedure is to be stated such as, the temperature, what kind of vessel is used, and total time is taken.
The second kind of measuring and testing of the coating quality of Painted Steel Coil is to be done with the rotating viscometer especially if using plastisol and (PVC).
Color & Gloss
For checking the quality of color colorimeter is used to measure the quality and durability of the color it gives excellent adhesion color coating. Furthermore, the calibrated instrument is used to measure the properties and checking procedure.
In this process, the light is placed onto the surface. The beam of light reflected from the equipment analyses the quality.
Paint cure is the quickest test done to the Painted Steel Coil. In this quality test chemicals used MEK (methyl ethyl ketone, butane-1-one) to soak the cotton wool and rubbing it onto the product to see if the color cracks or penetrate.
This chemically cross-linking tells the quality of a product because it withstands even by the hundreds of rubs of this quality testing.
Another quality test is used to check the reliability of the coating of the Painted Steel Coil. The quality test is taken by being gouged to it with the different hardens of a pencil.
The quality test of the flexibility of a product is done to analyze if the cracking happens. Three tests take for this quality test.
First, the T-bent test is taken, Painted Steel Coil is bent back onto its surface to see if the cracking happens.
Second, the Erichsen cupping test is taken to check the ductility of the coating of the Painted Steel Coil.
The third method is the reverse impact test taken on in.
What is Curing of a Painted Steel Coil?
Curing paints have many variations and advances in the Painted Steel Coil coating line. It is necessary to remove the solvents and cure the paint.
