Ningbo, Zhejiang,<\/strong> China – <\/strong>September 17<\/strong>, 2026<\/strong><\/p>\n

Steel Grating<\/strong><\/a> comes in many configurations, each designed to meet specific load, safety, and environmental requirements. At NJMM, we manufacture a high-performance grating variant that combinesserrated bearing bars<\/strong>, round bars inserted between the serrated<\/strong>, and twisted bar<\/strong>, all permanently fused through resistance welding. This design delivers outstanding slip resistance, structural stability, and drainage efficiency—making it ideal for industrial walkways, operating platforms, Stair Tread<\/strong><\/a>s, and drainage covers.<\/p>\n

Understanding the Construction<\/p>\n

This grating design integrates several distinct elements, each contributing to the panel’s overall performance.<\/p>\n

Serrated Bearing Bars:<\/strong> The primary load-carrying members run longitudinally and feature a serrated (toothed) top edge. This profile dramatically increases friction, providing superior slip resistance even in wet, oily, or icy conditions. Serrated bearing bars are a standard safety feature in industries where worker safety is critical.<\/p>\n

Round Bars Inserted Between Serrated:<\/strong> Round steel bars are positioned between the serrated teeth of the bearing bars. This adds lateral stability and helps maintain consistent spacing, while also contributing to the panel’s overall rigidity. The round bars sit within the serration pattern, creating a dense, uniform grid.<\/p>\n

Twisted Bar:<\/strong> Twisted square steel (also known as twisted bar) serves as the transverse cross rod, running perpendicular to the bearing bars. The twisting action creates a textured surface that enhances grip and provides additional lateral support.<\/p>\n

Resistance Welding:<\/strong> All components—bearing bars, round bars, and twisted cross rods—are permanently fused together using the resistance welding process. This method applies heat and pressure simultaneously, creating a strong, integral bond at every intersection without weakening the base material.<\/p>\n

Full-Seam Edge Banding:<\/strong> The panel is finished with a banding bar (edge plate) welded to the bearing bars using a full-seam, single-sided welding technique<\/strong>. This provides a clean, finished edge that adds structural integrity and protects the panel during handling and installation.<\/p>\n

Orderly, Open Grid Pattern:<\/strong> The resulting grid is neat, uniform, and highly transparent. The open area allows for excellent drainage, ventilation, and light transmission.<\/p>\n

Key Performance Advantages<\/p>\n

This grating configuration offers several benefits that make it suitable for demanding industrial environments.<\/p>\n

Superior Slip Resistance<\/p>\n

The serrated bearing bars are the primary safety feature. The toothed surface bites into footwear, providing reliable traction. The twisted cross rods add a secondary layer of grip. Together, they create a walking surface that performs well even in challenging conditions.<\/p>\n

High Load-Bearing Capacity<\/p>\n

Resistance welding creates a rigid, monolithic panel. The bearing bars carry the load, while the round bars and cross rods maintain spacing and distribute forces. The full-seam edge banding further reinforces the panel perimeter. This combination delivers stable, reliable load-bearing performance.<\/p>\n

Efficient Drainage and Ventilation<\/p>\n

The open-grid structure allows water, oil, and debris to pass through freely, preventing accumulation on the walking surface. This reduces slip hazards and extends the life of the platform. Ventilation also helps dissipate heat and fumes in industrial settings.<\/p>\n

Clean, Professional Appearance<\/p>\n

The orderly grid pattern and smooth edge banding give the panel a finished, professional look. This makes it suitable not only for functional industrial applications but also for visible installations where appearance matters.<\/p>\n

Custom Fabrication<\/p>\n

Panels can be cut to exact dimensions or manufactured according to customer drawings. This ensures a precise fit for any platform layout, including irregular shapes, cutouts for equipment, and curved edges.<\/p>\n
