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.
