Metal sheets are thin and flat parts that have a wide range of applications. Aluminum sheets, which are also called aluminum plates, are the result of pressing raw aluminum and rolling it into plates. The aluminum sheet is made very thin and light, and at the same time it is strong enough to be easily installed and maintained, and it has great flexibility.

Aluminum sheet is made of light aluminum metal; due to its light weight and high strength in various industries such as: It is used in automobile manufacturing, airplane manufacturing, construction and household appliances. All kinds of aluminum sheets are produced during different stages; If all the processes are done correctly, they will increase the quality of these sheets.

What is aluminum sheet?

Aluminum ranks second after iron and steel in the world market. Aluminum is light weight, but the strength of some of its alloys is higher than construction steel. It has good electrical and thermal conductivity and is a good reflector for light and heat. Aluminum has high corrosion resistance in practical conditions and is a non-toxic metal.

The method of producing aluminum sheets

The production steps of aluminum sheet are as follows:

The raw material of aluminum sheet is aluminum ingot, usually they melt the aluminum ingot, and put the molten aluminum in continuous casting. The thickness of the casting roll is between 8-10mm, which is the first step in the production of aluminum sheet.
Then the end rolling mill is subjected to repeated concentration of the casting roll to the desired thickness. This is the second step in the production of aluminum sheet.
In the third step, it comes to refining and cleaning the casting roll, the refining is to refine the irregular edge of the roll, and the cleaning is due to the rolling mill in the case of the rolling material inside the rolling oil, the surface oil must be cleaned.
At the end of annealing and packaging, the annealing is placed in a constant temperature annealing furnace for a while, through high temperature to change the internal grain size of the aluminum sheet to obtain a variety of mechanical and tensile properties, and then after finishing annealing. , through equipment for open processing, then packaging for all kinds of packaging.

All kinds of aluminum sheets

All kinds of aluminum sheets are available in different thicknesses. Aluminum is corrosion resistant and maintenance free. It has an excellent strength-to-weight ratio compared to other metals, weighing about one-third as much as iron, steel, copper, or brass. Aluminum plate has better thermal conductivity than any other metal.

Perforated aluminum sheet

It is used in scenarios that are mainly chosen because of its beauty features. This is especially used in interior and exterior design works, for example, in the construction of various types of roofs, screens, solar shades and other architectures. It is used in places where its appearance is important.

Colored aluminum sheet

Colored sheets called “RAL”, which is a kind of color coding system, are implemented and provided by manufacturers in standard designs and colors. It is produced and marketed in various designs in the industry. Thin colored aluminum sheet is used in the decoration industry, cabinet making, roofs of houses or halls, etc. and is used in wavy or sheet forms.
