Steel Flat Bars (C.R.)

Everything You Need to Know About C.R. Steel Flat Bars (Cold Rolled)

A C.R. steel flat bar (Cold Rolled) is a solid steel product with a rectangular cross-section manufactured through a cold rolling process. This process generally provides greater dimensional accuracy, a more uniform surface, and tighter tolerances than hot rolled products.

Thanks to their rectangular cross-section and dimensional characteristics, cold rolled steel flat bars are used in various metal fabrication, machining, construction, and assembly projects.

At Groupe David, C.R. steel flat bars are available in 1018 steel.

Cold rolled flat bars offer several useful characteristics for fabrication and machining applications.

Their main advantages include:

Good dimensional accuracy
More uniform surface with a better finish
Good straightness and tighter dimensional tolerances
Good machinability depending on the selected grade
Rectangular cross-section providing flat surfaces
Suitable for various fabrication and assembly applications
Cutting and bending options according to project requirements

The product should be selected according to the technical requirements and intended use.

Cold rolled and hot rolled flat bars are manufactured using different processes and have distinct characteristics in terms of finish, dimensional accuracy, and application.

C.R. Flat Bar (Cold Rolled)

Smoother and more uniform surface
Tighter dimensional tolerances
Good straightness
Suitable for applications requiring greater precision
Good option for machined parts and fabrication projects

H.R. Flat Bar (Hot Rolled)

Generally rougher surface
Generally wider dimensional tolerances
Suitable for a wide variety of fabrication and construction applications
Available in different dimensions and grades

For projects requiring the specific characteristics of hot rolling, also consult our page on H.R. steel flat bars (hot rolled).

The choice between the two products depends primarily on the required dimensions, finish, desired level of precision, and project requirements.

At Groupe David, cold rolled steel flat bars are available in 1018 steel.

1018 steel is a low-carbon steel known for its good machinability, formability, weldability, and versatility. It can be suitable for various fabrication, machining, and assembly applications.

The material should nevertheless be selected according to the required mechanical properties and specific project requirements.

At Groupe David, C.R. steel flat bars are available with the following specifications:

Lengths: between 10 and 14 feet (≈ 3.05 to 4.27 m)
Thicknesses: from 1/8″ to 4″ (≈ 3.18 to 101.6 mm)
Widths: from 3/8″ to 12″ (≈ 9.53 to 304.8 mm)
Grade: 1018

Available dimensions may vary depending on the product.

To view the available dimensions, consult pages 28 to 34 of our catalogue or contact our team.

Custom cutting services may also be available according to your project requirements.

C.R. steel flat bars can be used in a variety of industrial, manufacturing, and mechanical applications, including:

Manufacturing of parts and components
Machined parts
Metal supports and reinforcements
Manufacturing of frames and structures
Machinery and equipment components
Tooling and fixtures
Metal fabrication work
Custom fabrication projects

They are particularly useful for applications requiring good dimensional accuracy and a more uniform surface.

Choosing the right cold rolled steel flat bar depends primarily on several criteria.

Steel Grade

C.R. flat bars offered by Groupe David are available in 1018 steel. The material should be selected according to the required mechanical properties and application requirements.

Dimensions

Dimensions should be selected according to:

The dimensions of the part or structure to be manufactured
Design requirements
The required thickness and width
Cutting and fabrication requirements

Finish and Precision

Cold rolled bars are particularly useful when surface quality, straightness, and dimensional accuracy are important.

For applications where these characteristics are less critical, a hot rolled steel flat bar (H.R.) may also be an option to consider.

Our team can help you select the steel flat bar best suited to your application.

The price of cold rolled steel flat bars varies depending on several factors, including:

Bar dimensions
Required length
Order quantity
Required cutting or bending services
Steel market conditions
