FAQ – Everything You Need to Know About Cold Rolled Steel Square Bars
A C.R. (Cold Rolled) steel square bar is a solid steel product with a square cross-section produced through a cold rolling process. In general, this process provides improved dimensional accuracy, a more uniform surface finish, and tighter tolerances compared to hot rolled bars.
Cold Rolled steel square bars are particularly valued for applications requiring a high-quality surface finish, excellent machinability, and high dimensional precision.
Unlike hot rolling, which shapes steel while it is heated to high temperatures, cold rolling is performed at room temperature to improve the dimensional accuracy, straightness, and surface quality of the finished product.
H.R. (Hot Rolled) steel square bar
- Rougher surface finish
- Wider dimensional tolerances
- Suitable for structural and general applications
- Generally more economical
C.R. (Cold Rolled) steel square bar
- Smooth and uniform surface finish
- Tighter dimensional tolerances
- Improved straightness
- Ideal for machined parts and precision applications
Cold Rolled bars are therefore preferred when surface quality and dimensional accuracy are important factors.
At Groupe David, Cold Rolled steel square bars are available in several grades designed to meet different mechanical requirements.
1018 Steel
- Low carbon steel
- Excellent machinability
- Good weldability
- Good surface finish after machining
- Ideal for general mechanical components
1045 Steel
- Medium carbon steel
- Higher mechanical strength than 1018
- Good balance between strength and machinability
- Used for shafts, axles, and mechanical components
4140 Steel
- Chromium-molybdenum alloy steel
- High mechanical strength
- Good wear and fatigue resistance
- Suitable for demanding industrial applications
C12L14 Steel
- Excellent machinability
- Produces excellent part finishes
- Recommended for high-volume machined components
At Groupe David, Cold Rolled steel square bars are available with the following specifications:
- Dimensions: 1/8’’ (≈ 3.2 mm) and up
- Length: between 10 and 14 feet (≈ 3 to 4.3 metres)
Custom cutting is also available depending on your project requirements.
Cold Rolled steel square bars are used in a wide range of industrial and mechanical applications, including:
- Machined parts
- Machinery components
- Tooling
- Jigs and fixtures
- Support and frame fabrication
- Industrial equipment
- Custom fabrication projects
- Precision part manufacturing
They are especially valued when dimensional accuracy and surface quality are important.
The selection depends on several criteria.
Application type
- Machining
- Fabrication
- Mechanical applications
- Tooling
Steel grade
- 1018 for general applications
- 1045 when higher strength is required
- 4140 for high-strength and high-performance applications
- C12L14 when machinability is the priority
Dimensions
- Based on project requirements
Surface finish requirements
- Cold Rolled (C.R.) square bars are recommended when tight tolerances and improved surface quality are required.
- For applications where precision is less critical, a Hot Rolled (H.R.) square bar may represent a more economical solution.
Our team can help you select the grade and dimensions best suited to your application.
