How To Choose The Right Carbon Steel Sheet Metal Material
When looking at the correct carbon steel sheet metal for your manufactured parts, there are several types to pick. A few basic questions exist that need answering before choosing the right material:
- Will the parts be cut using a laser, plasma, or punched?
- Will the parts finished be indoors or outdoors?
- Does your parts need to be painted?
- Does your parts need to have a better finishing?
These are some of the factors used in choosing the correct type of sheet metal material. Today, we will take this article to introduce the carbon steel sheet material characteristic.
Below are main carbon steel material type and specification.
-
Galvanized Steel Sheet
How to form a galvanized sheet from a carbon steel sheet is by using a continuous hot-dip process. It coats the carbon steel with zinc on both sides. The zinc coating possesses an added advantage by improving the properties of carbon steel. It becomes more laborious than a regular galvanized coating and is more resistant to scratching and manufacturing damage. However, one disadvantage is the harder coating being susceptible to powdering if the sheet is severely formed during fabrication.
Creatingway advocates Galvanized sheet specific use in the painted condition. When painted, the combined paint/galvanized coating offers perfect resistance to peeling and blistering. It also improves the corrosion resistance of the paint, compared with the conventional galvanized sheet. It is after the careful selection of primers and paints used in the painting process.
For the main application, we recommend the use of galvanized steel in painted parts and parts that remaining outside during its use. For processing, it can be laser cut, punched, and formed with exceptional results. The overall surface finish, adhesion, and paint quality are usually best with galvanized material.

Hot Rolled Sheet
The process of forming hot rolled sheets is by rolling material at elevated temperatures on rolling mills. It generates material that is resistant to work hardening and exhibits reduced levels of deformation residual stress. The addition of a process downstream is necessary to eliminate coil memory. It includes temper passing or stretcher leveling. One major demerit is hot-rolling leaves surface imperfections such as scale or pits which require additional finishing for a smooth surface.
If you are a customer keen on saving expenditure, hot rolled steel (HRS) is the ideal metal sheet for you. Especially when the cost is more important than the surface finish. For processing, it is mainly punched instead of being cut on the laser. Forming a hot-rolled sheet is not a complicated process, thus allowing us to process on time.
-
Cold Rolled Sheet
The key role of cold rolling is to treat hot rolled steel sheet further. It results in an increase in strength and the strength-to-weight ratio of the final rolled metal sheet. It enables it to hold tighter tolerances during fabricating and machining. The process results in a stiffer material, smooth surface, and more consistent metal thickness. It is possible by compression of the grain structure of a hot-rolled sheet during the cold rolling process.
Painting immediately of parts made from a cold-rolled sheet is necessary to prevent surface rust. Processing of cold-rolled sheet is by laser cutting, punching, and forming with excellent results. The surface finish of painted parts is usually exceptionally good with a cold-rolled sheet.
What Factors did the carbon steel sheet metal material have?
In picking the right sheet metal for your next project, there are lots of options. You must compare up the options carefully as there is a possibility of compromising both function and form. With that in mind, our experts at Creatingway present what we suggest are the most crucial sheet metal selection criteria to consider.
-
Strength
Strength becomes vital if you need metal to bear heavy loads. A polished sheet of aluminum looks excellent but does not offer much in the terms- of tensile strength. That is unless you form it into a profile, which gives it more rigidity.
-
Corrosion resistance
Examples of metal sheets that do not corrode stainless, aluminum and copper but develop oxide films. For cold-rolled steel, it rusts quickly if left unprotected thus we paint to protect the metal sheet surface.
-
Appearance
The finishing process vary when dealing with metal sheet fabrication. It does not matter too much what the sheet metal looks like If you are applying a plated, painted or powder finish. Some applications require the bare metal look thus skipping the finishing process.
-
Formability
For sheet metals, some are easier to bend than others. Stainless steel is very prone to cracking on bending. Most aluminum grades, for example, are very ductile while low carbon steels fall somewhere between the two. We use the feature of easy formability to our advantage to combining separate pieces. It effectively replaces welding or screwing with bending. It simplifies assembly and reduces piece count, thus a bonus for easily formed metals.
