What is the colored plate?

Colored sheets are the metal plates that are colored by furnace or other special techniques such as electrostatic and it is considered one of the most important and most used metal plates .
Colored sheet is originally galvanized, coated with colored paint, and a premium for its beautiful design . This paint gives it more resistant and immunity to inappropriate weather conditions or, for example , its proximity to acidic liquids ;
This is one of the properties that has made this type of plate used in many fields
Because of its stainless and flexibility , These galvanized sheets are used in construction industries such as false ceilings, warehouse packaging, storage, , cabinetry, and so on .

Types of galvanized sheets

In general, galvanized sheets are are produced in two forms : rolled galvanized sheets and fabricated galvanized sheets ; we will explain it below :
In the coil industry, While making the galvanized sheet in roll form, the sheets are cut across the width, not split longitudinally, and will be folded in roll-shaped by the roller .
Fabricated galvanized sheets are those that are cut at the factory with specific dimensions or Length Widt and delivered to customers as requested .
The most important advantages of fabricated galvanized sheets is the quality of their polishing , smoothing and flatness which is widely used in industrial applications .

How is color plates produced ?

In order to produce the colored galvanized sheet, first they placed the rolls or coils inside plate preparation machine ; then they polished the surface on the sheets to remove the grease the impurities and then the sheets are placed in special rollers to perform the brushing operation ;
The brushes make the surface perfectly polished and overall the brushing operation helps the color to sit better on the sheet and not to pits .
Chemical materials are used to make the paint stick to the sheet, and after the drying process, They perform the coloring operation .
Initially, a single layer of paint is applied to the surface of the plates , and then it passes through the basic painting stage .
After the base color has dried , They are coated with polyester colors , and then They are colored with a roller.
And then the plates are entered the baking stage and passed through the oven and after cooling , the plates are ready to be used in various industries .
In some cases, the following methods may be used as layering for color galvanized sheets to suit the color requirements of the environment :

Hot galvanized steel

Zinc is used in the manufacture of hot galvanized steel as a protectorand preservative material , and then the steel sheet is placed in a molten zinc furnace and baked on it . The property of using zinc metal is to protect the steel from corrosion .

Electro galvanized steel

The manufacture of Electro galvanized steel or hot and cold galvanized plating is the process In which, the metal sits on the steel and protects it from corrosion .
In fact, the use of this method is more economical, because it will require the furnace and other equipment to be hot-dipped and expensive to manufacture galvanized steel .
