Welded vs Press Locked vs Round Bar Press-Locked Grating: Structural Differences Explained

Choosing the right grating type is essential for safety, performance, and long-term cost efficiency. Among the most commonly used types, welded grating, press locked grating, and round bar press-locked grating each offer distinct structural characteristics.
As a professional steel grating manufacturer, we help clients select the most suitable grating based on application requirements, load conditions, and environmental factors.

What Is Welded Steel Grating?

Welded steel grating is manufactured by resistance welding bearing bars and cross bars together under high pressure and temperature. This creates a rigid and durable structure that is widely used in industrial environments.

  • Strong and cost-effective
  • Suitable for heavy-duty applications
  • Widely used for platforms and walkways

Due to its strength and versatility, welded grating is one of the most common forms of steel bar grating used in construction and industry.


What Is Press Locked Steel Grating?

Press locked grating is produced by inserting cross bars into pre-punched bearing bars under high pressure, without welding. This creates a clean and smooth appearance while maintaining good structural integrity.

  • Uniform and aesthetically pleasing
  • No welding points
  • Ideal for architectural and decorative applications

It is commonly used in projects where appearance matters, such as commercial buildings and public spaces.


What Is Round Bar Press-Locked Grating?

Round bar press-locked grating is a variation of press locked grating where round bars are used as cross bars instead of flat bars. This design enhances visual appeal and drainage performance.

  • Improved drainage and airflow
  • Modern architectural appearance
  • Lightweight yet strong

It is often selected for high-end architectural projects and specialized industrial environments.


Key Structural Differences

Feature Welded Grating Press Locked Grating Round Bar Press-Locked
Manufacturing Method Resistance welded Press locked (mechanical locking) Press locked with round bar cross bars
Strength High Medium Medium
Appearance Industrial Clean & Uniform Architectural
Drainage Good Good Excellent
Applications Heavy industry Commercial Architectural & design

How to Choose the Right Grating Type?

Selecting the appropriate grating depends on your project requirements:

  • For heavy load and industrial use: Welded grating is the best choice
  • For clean appearance and precision: Press locked grating is recommended
  • For architectural and drainage performance: Round bar press-locked grating is ideal

In environments requiring additional safety, combining these structures with serrated surfaces can significantly improve slip resistance.


Conclusion

Understanding the structural differences between welded, press locked, and round bar press-locked grating helps ensure optimal performance and cost efficiency for your project.
