FAQ – Everything You Need to Know About Hot Rolled Steel Square Bars
A H.R. (Hot Rolled) steel square bar is a solid steel product with a square cross-section manufactured through a high-temperature rolling process. This process produces strong and versatile bars suitable for general, structural, and metal fabrication applications.
Hot Rolled steel square bars are particularly valued for their mechanical strength, ease of fabrication, and excellent cost-to-performance ratio.
The main difference between H.R. and C.R. steel square bars lies in the manufacturing process, surface finish, and dimensional accuracy achieved.
H.R. (Hot Rolled) steel square bar
- Manufactured at high temperatures
- Rougher surface finish with an industrial appearance
- Wider dimensional tolerances
- Good mechanical strength
- Ideal for structural and general applications
- Generally more economical
C.R. (Cold Rolled) steel square bar
- Manufactured through a cold rolling operation at room temperature after the initial rolling process
- Smoother and more uniform surface finish
- Tighter dimensional tolerances
- Improved straightness
- Ideal for machined parts and precision applications
Hot Rolled steel square bars are therefore preferred when strength, versatility, and cost are important factors.
At Groupe David, Hot Rolled steel square bars are available in two structural steel grades commonly used for industrial and structural applications.
44W Steel
- Versatile structural steel grade
- Good mechanical strength
- Good weldability
- Used for general fabrication and construction applications
50W Steel
- Structural steel grade offering a higher yield strength than 44W
- Better load-bearing capacity
- Recommended for structures requiring increased strength
- Used in demanding industrial and structural applications
The choice of grade mainly depends on the mechanical requirements and project constraints.
At Groupe David, Hot Rolled steel square bars are available with the following specifications:
- Dimensions: 3/8’’ and up
- Standard length: 20 feet (≈ 6.1 metres)
Custom cutting is also available depending on your project requirements.
Hot Rolled steel square bars are used in a wide range of industrial, commercial, and structural applications, including:
- Metal structure fabrication
- Structural supports and reinforcements
- Metal frames and chassis
- Welded mechanical components
- Machinery and industrial equipment fabrication
- Structural steel construction projects
- Custom fabrication projects
They are particularly valued in applications where mechanical strength and ease of fabrication are priorities.
The selection depends on several criteria:
Application type
- Metal structures
- Welded fabrication
- Supports or reinforcements
- Construction projects
Steel grade
- 44W for general applications
- 50W when higher mechanical strength is required
Required dimensions
- Based on load requirements and project constraints
Surface finish requirements
- Hot Rolled (H.R.) square bars are recommended for general and structural applications where dimensional precision is less critical.
- Cold Rolled (C.R.) square bars are preferred when tighter tolerances and improved surface finish are required.
Our team can help you select the grade and dimensions best suited to your application.
Pricing varies depending on several factors:
- Steel grade (44W or 50W)
- Dimensions
- Length
- Order quantity
- Required cutting or processing
- Steel market conditions
For accurate pricing, we recommend requesting a quotation.
