How To Choose A Prepainted Steel Coil?
1. Price
It mainly refers to the price of raw materials, base steel or cold rolled sheet components supplied by suppliers. The price of raw materials determines the price of color coated coils and the input-output ratio of the entire supply chain, which results in profit margins for producers and sellers. A certain degree of influence.
2. Quality
First, confirm all the details of the order, including thickness, width, color, packaging, roll weight, etc., as well as the application environment of the selected raw material.PPGI's quick and easy testing methods are: machines to test paint thickness and coil thickness and width, T-bend to test paint adhesion, and testing zinc layer. Or you can make an appointment with a professional testing agency such as SGS for sampling to better define product quality.
Coating hardness
The coating hardness is the ability of the coating to resist scratch, abrasion, impact, press and other mechanical functions, which is closely to the scratch resistance, abrasion resistance and indentation resistance of PPGL coil. It is chosen mainly based on applicaiton, processing methods, storage and transportation conditions and other factors. Coating’s flexibility, adhesion is closely to the processing of PPGL coil, mainly based on processing method, the degree of deformation and so on to choose.

Coating durability
Coating durability is the performance that PPGL coil show in usage, usually measured by the length of service life. Coating durability and painting types, coating thickness, the corrosiveness of the environment and other factors are closely related. Atmospheric exposure test is a reliable method to evaluate the durability of the coating. People have developed a series of artificial aging test to evaluate the durability, neutral salt spray test and UV test are more commonly used .
Other properties
In some conditions, PPGL coil is required good resistance to organic solvents, acid and alkali resistance, stain resistance and other properties. PPGL coil supplier choosing the performance of reverse coating usually depends on the applicaiton and environment. When corrosive environment is not high, the reverse is usually only coated with a layer, for decoration. Due to high corrosiveness of the environment, two layers are applied to improve the corrosion resistance.

3. On-time delivery
If you confirm the time period with the factory, you need to confirm the delivery time and other subsequent plans. So delivery time is also important. This factor directly affects the arrival date and sales volume of the customer's products. Therefore, delivery punctuality should be considered. Choose a more rigorous factory.
Buying color coated steel coils from the manufacturer
Color coated steel coils are available in a variety of shapes and sizes according to the specific needs of the customer. This is known for its outstanding properties and attributes that make it worthy and admired by various industrial applications.
To procure color coated steel coils, get them from Xinnuoda Steel Supply. These offer you the best quality products at reasonable and reliable prices.
