Cold rolled and hot rolled steels are two essential materials used across various industries. In the appliance manufacturing sector, cold rolled steel is favored for its smooth surface, dimensional precision, and excellent formability.
When sourcing steel for home appliances, one of the first questions is: cold-rolled vs hot-rolled steel – which should you choose? Let’s break down the differences, applications, and which material fits your needs under keywords like appliance cold rolled steel or hot rolled steel for appliances.
Cold rolled steel is produced by further processing hot rolled steel at room temperature. After hot rolling, the steel is pickled (to remove scale), then rolled in a cold reduction mill, which compresses the steel into precise dimensions and improves its surface quality.
Cold-rolled steel is widely used for appliance bodies and panels coined as “appliance cold rolled steel“. Its smooth surface, tight tolerances, and formability make it ideal for manufacturing refrigerators, washing machines, and other home appliances.
This process enhances the material’s:

Common forms of cold rolled sheet metal include:
Hot rolled steel is processed at high temperatures (above the recrystallization point), typically above 1,700°F (926°C). This allows the steel to be shaped and formed easily. However, as the material cools, it shrinks slightly, making its final dimensions less precise than cold rolled steel sheet.
Typical characteristics of hot rolled steel:
In contrast, hot-rolled steel for appliances offers lower cost and greater structural thickness, but a rougher surface that needs further finishing. It can be a choice for internal frames or support components in appliances.
Let’s break down the difference between hot rolled and cold rolled steel in a quick comparison chart:
| Feature | Cold Rolled Steel | Hot Rolled Steel |
|---|---|---|
| Manufacturing Temperature | Room temperature (after hot rolling) | >1,700°F (hot rolled directly from billet) |
| Surface Finish | Smooth, uniform, matte or shiny | Scaled, rough surface |
| Dimensional Precision | High tolerance | Lower tolerance |
| Strength | Higher (after work hardening) | Lower |
| Formability | Excellent (after annealing) | Fair, better for bending without cracking |
| Applications | Appliances, furniture, automotive components | Construction beams, welding structures |
| Thickness Tolerance | Tight control, uniform across the coil | Variable across sheet width |
| Cost | Higher due to processing | Lower, less processing |
In short, cold rolled steel is stronger and smoother, while hot rolled steel is more economical and flexible for large-scale structural use.

When it comes to home appliance manufacturing, cold rolled steel is the clear choice due to its surface finish, forming ability, and consistent thickness. Many appliance parts require a premium appearance and precise fitting—qualities that are difficult to achieve with hot rolled metal sheet.
Common used in:
In contrast, hot rolled steel is rarely used for these visible or precision parts due to its rough surface and scale.
Hot rolled steel excels in construction, shipbuilding, and industrial equipment, where aesthetics are less critical, but strength and cost matter more. Typical uses of hot rolled steel sheet include:
Because hot rolled versus cold rolled steel involves differences not only in finish but also in mechanical behavior, they are not interchangeable in most industrial applications.
The answer is yes, but with some conditions.
Cold rolled steel is typically stronger than hot rolled steel due to work hardening that occurs during cold rolling. However, it may also become more brittle unless annealed.
The hot rolled vs cold rolled strength difference depends on:
For high-stress parts in appliances (e.g., internal brackets or drawer supports), the added strength of cold rolled metal is ideal.
Appliance manufacturers prefer cold rolled metal because of:
CJM offers CRS steel with customizable coil width, thickness, edge condition, and coating options to meet appliance production needs.
Let’s address a few final questions that buyers often search:
A: It’s the difference in production temperature.
A: Construction beams, support structures, base plates, welded frames
A: Appliance panels, cabinets, furniture, auto parts, electrical enclosures
A: It refers to steel used for home appliance bodies, valued for its smooth surface and precision tolerances.
A: Yes, but it’s better suited to internal structures; for external panels, cold-rolled steel is preferable.
A: Cold-rolled steel is formed through rolling at room temperature, yielding higher strength and better surface finish, ideal for appliances.

| Use Case | Recommended Steel Type |
|---|---|
| Appliance panel or frame | Cold rolled steel (CRS) |
| Refrigerator backplate | CRS material, SPCC grade |
| Air conditioner housing | Cold rolled sheet metal, coated |
| Construction beam | Hot rolled steel sheet, HRS |
| Large machine frame | Hot rolled steel |
| Painted or pre-coated part | Cold rolled steel (prepainted or skin-passed) |
For visible or precision components, CRS steel is the optimal choice. For structural or welded assemblies, hot rolled steel may offer better value and workability.
