Press-locked Steel Grating
Press locked grating is a durable and visually appealing metal grating manufactured by mechanically pressing pre-punched bearing bars and cross bars together under high hydraulic pressure to form a strong interlocking structure. Unlike welded grating, it does not rely on welding during the main assembly process, offering greater design flexibility and a cleaner appearance. It is widely used in architectural applications, including sunshade systems, mezzanine floors, security partitions, platforms, and vehicle access ramps.
With its unique manufacturing process, press locked grating provides extensive customization options in terms of mesh size, bearing bar dimensions, materials, and surface designs. This flexibility allows it to meet the specific requirements of different projects while maintaining excellent strength, stability, and aesthetic appeal.
Manufacturing Process of Press Locked Grating
Press locked grating is manufactured by inserting cold-rolled flat steel cross bars into pre-punched bearing bars under high pressure, creating a strong mechanical interlocking structure. This Steel Grating design provides a secure connection without relying solely on welding. The edges are reinforced with flat or T-shaped banding bars through resistance welding to enhance overall stability.
For applications requiring improved safety, serrated surfaces can be added to the bearing or cross bars to provide better slip resistance. Available in various materials, mesh sizes, and surface finishes, press locked grating can be customized to meet the specific requirements of industrial, commercial, and architectural projects.

Key Features of Press Locked Grating
Press locked grating combines structural strength, design flexibility, and aesthetic appeal, making it suitable for both industrial and architectural applications. Its unique interlocking structure provides excellent rigidity while allowing for a wide range of customization options.
Press locked grating combines structural strength, design flexibility, and a clean appearance, making it suitable for both industrial and architectural applications. With its secure interlocking structure and flexible configuration options, it provides reliable rigidity while adapting to different project requirements. Dunqiang offers press locked grating with various specifications and finishes to support different functional and design needs.
- Clean and Attractive Appearance:The flush, uniform surface without visible welds creates a modern and neat appearance, making it ideal for architectural applications such as facades, ceilings, partitions, and decorative screens.
- Strong and Rigid Structure: The high-pressure locking process firmly joins the bearing bars and cross bars, creating a strong and durable structure with excellent load-bearing capacity and lateral stability.
- Flexible Material Options: Press locked grating comes in carbon steel, stainless steel, and aluminum to suit different requirements for strength, weight, corrosion resistance, and appearance. Galvanizing and powder coating can further enhance surface protection and service life.
- Customizable Design: Different mesh sizes, bearing bar shapes, and bar thicknesses provide greater flexibility for project-specific requirements. These options allow the grating to adapt to a wide range of structural, functional, and design needs.
- Enhanced Safety Performance: Serrated bearing bars or cross bars improve slip resistance, making press locked grating a safer choice for industrial walkways, stair treads, platforms, and other areas where secure footing matters.
Applications of Press Locked Grating
Press locked grating suits a wide range of architectural, industrial, and public infrastructure projects, combining a smooth flush surface, strong interlocking structure, and attractive appearance. It works well for walkways, platforms, stair treads, facades, and decorative structures where both reliable performance and visual appeal matter.
- Architectural & Decorative Applications: The clean, weld-free surface makes press locked grating an excellent choice for modern building designs, including exterior facades, sunshades, balcony panels, decorative partitions, ceiling systems, and security screens.
- Pedestrian Walkways & Platforms: With precisely controlled bar spacing and a smooth walking surface, it provides a safe and comfortable solution for pedestrian areas, including shopping centers, transit stations, bridges, and wheelchair-accessible walkways.
- Municipal Infrastructure: Press locked grating provides a practical solution for trench covers, drainage covers, cable pits, and ventilation grilles in urban roads, tunnels, and public facilities. Its open design allows air, light, and water to pass through efficiently while providing reliable structural support.
- Industrial Flooring & Platforms: Its rigid structure and high load-bearing capacity make it suitable for industrial platforms, mezzanine floors, equipment platforms, and maintenance walkways in factories, refineries, chemical plants, and other heavy-duty environments.
- Stair Treads & Access Systems: Press locked grating provides excellent strength, durability, and slip resistance, making it a reliable choice for stair treads, fire escape steps, and industrial access stairs. Its rigid structure supports frequent use while the slip-resistant surface helps provide secure footing.
