Choosing the Right Hot Rolled Steel Coil:

When selecting a hot rolled steel coil, it is important to consider the specific application requirements. Factors to consider include the grade of steel, the dimensions of the coil, the surface finish, and the required properties. It is also important to work with a reputable supplier to ensure that the hot rolled steel coils meet the highest quality standards.

On the market today, steel coil is a commonly used type with many different types. However, many people still do not distinguish between the types of steel coils and their uses. Let's find out more about MRS Steel in the following article.

1. What is a steel coil? 

The steel coil is a steel type that is quite commonly used today. This type of steel is produced with a smooth or ribbed surface that is curled together. Making quality steel coils requires a complex steel production process that requires high technical and technological qualifications. Depending on the needs and purposes of use, there will be different types of steel coils.

2. Application and classification of steel coil 

2.1 Hot rolled coil 

Hot-rolled coil is the finished product of the process of smelting, casting billets, and hot rolling at a temperature of °C. This steel is the raw material for creating cold-rolled coil, welded steel tubes, and cast steel pipe. Normally, a hot-rolled coil will have a blue-black color and a rough surface that is less aesthetic.

Hot-rolled coils are commonly used in the automobile industry, railways, shipbuilding, roofing corrugated iron, the production of H- and I-shaped steel beams, moving floors, ladders,...

2.2. Cold rolled coil 

The cold-rolled coil is a hot-rolled coil after cooling and re-rolling at room temperature to produce cold-rolled coil products with the desired shape and size. This process will not change the structure of the steel, but only the shape of the steel in accordance with the needs and purposes. However, if the cold rolling process is not strictly controlled, it will deform the product. The cold-rolled coil has a smooth surface, so it ensures higher aesthetics and durability.

Cold-rolled coils are often used to make flat sheet products such as steel plates, coils, laminates, round and square details,.. and products with smooth surfaces. 

2.3. Galvanized steel coil

The galvanized steel coil is a cold-rolled coil that is additionally plated with a layer of zinc on the outside of the surface. This is one of the most influential and economical methods of protecting steel from corrosion under the influence of the environment.

Galvanized steel coils are widely used in building architecture, roofing, ventilation systems, solar water heaters, televisions, refrigerators, the automobile manufacturing industry, the manufacturing industry,...

2.4. Stainless steel coil

Stainless steel is a steel alloy with a minimum chromium content of 10.5%, which is a standard metal in Vietnam and is commonly known as stainless steel. Manufacturers often choose to use stainless steel as a metal production material because it has good corrosion resistance, oxidation resistance, high strength, and does not stain or rust. 

Stainless steel is commonly used in many industries and construction projects, such as aerospace, architecture, medical, home appliances, and jewelry...

2.5. Pre-painted steel coil

Pre-painted steel coil, also known as color-coated corrugated iron, is a type of corrugated iron made of galvanized steel coated with a layer of color paint to increase the aesthetics and longevity of the building. Pre-painted steel coil has high strength, good bearing capacity, corrosion and rust resistance, and many different designs and shapes suitable for each type of construction.

Pre-painted steel coils are used to make roofing sheets, rolling doors, interior decoration,... In addition, it is also used to make industrial electrical products, household appliances, insulation systems,...
