2. Types of Aluminum Grating

1. Swaged Aluminum Grating:
   • Crossbars are permanently locked to bearing bars using a swaging process, resulting in a rigid, durable panel.
2. Press-Locked Aluminum Grating:
   • Bearing and crossbars are pressed together under pressure, creating a smooth, clean surface.
3. Riveted Aluminum Grating:
   • Crossbars are riveted to bearing bars, offering exceptional strength for heavy loads.
4. Expanded Aluminum Grating:
   • A single aluminum sheet cut and stretched into a diamond-shaped mesh, providing lightweight and cost-effective solutions.

3. Dimensions

• Bearing Bar Size:
  • 두께: 3/16 inch (4.8 mm) 에게 1/4 inch (6.35 mm).
  • 깊이: 1 inch (25.4 mm) 에게 4 inches (101.6 mm).
• Spacing:
  • Standard bearing bar spacing: 7/16 inch (11.1 mm), 1/2 inch (12.7 mm), 또는 1 inch (25.4 mm).
  • Crossbar spacing: Typically 4 inches (101.6 mm) 또는 6 inches (152.4 mm).

4. Load Ratings

• Load capacities depend on bearing bar size, depth, and spacing. Aluminum grating is typically designed to support pedestrian traffic and light-to-moderate vehicle loads.

5. Finishes

• Mill Finish:
  • Natural aluminum surface, suitable for indoor or low-corrosion environments.
• Anodized:
  • Provides enhanced corrosion resistance and aesthetics, available in various colors.
• Powder-Coated:
  • Adds a layer of durability and visual appeal, with customizable color options.

6. Surface Options

• Plain Surface:
  • Smooth for general use; suitable for non-hazardous environments.
• Serrated Surface:
  • Offers slip resistance, ideal for wet, oily, or icy conditions.

7. Compliance Standards

• Meets industry standards such as:
  • NAAMM MBG 531: Guidelines for bar grating performance.
  • ASTM B221: Specifications for aluminum alloy extruded bars.

Manufacturing Processes

1. Extrusion:
   • Aluminum is extruded into bearing and crossbars with precise dimensions.
2. Swaging:
   • Crossbars are swaged into bearing bars for a secure and rigid fit.
3. Press-Locking:
   • Bearing and crossbars are mechanically locked under pressure.
4. Anodizing or Coating:
   • Surface treatments are applied to enhance durability and aesthetics.

Applications of Aluminum Grating
