2. Durable and Long-Lasting:

   • Resistant to wear and tear, ensuring longevity even under harsh conditions.
   • High resistance to impact and deformation.

3. 防滑:

   • Often manufactured with serrated surfaces or added traction features for enhanced safety.

4. 耐腐蚀性能:

   • Available with protective coatings such as galvanization or powder coating for improved performance in corrosive environments.

5. Open Design:

   • Allows for drainage, ventilation, and the passage of light, reducing water accumulation and ensuring better maintenance.

6. 可定制:

   • Can be tailored to meet specific load requirements, dimensions, and finishes for various applications.

Specifications of Heavy-Duty Steel Grating

1. Materials

• Carbon Steel:
  • Most common material, offering excellent strength and cost-effectiveness.
  • Typically hot-dip galvanized to prevent corrosion.
• Stainless Steel:
  • Provides superior corrosion resistance and is used in environments exposed to chemicals, moisture, or extreme weather.
• Alloy Steel:
  • Suitable for specialized applications requiring extra durability and resistance to wear.

2. Bar Dimensions

• Bearing Bar Size:
  • Thickness: Commonly ranges from 6mm to 15mm.
  • Depth: Ranges from 25mm to 200mm depending on load requirements.
• Spacing:
  • Common spacing between bearing bars: 30mm, 40mm, 50mm, or custom configurations.
  • Spacing between crossbars: 50mm or 100mm (standard).

3. Load Ratings

• Designed to support heavy vehicular loads (e.g., trucks, forklifts, cranes) and industrial machinery.
• Compliance with standards such as ANSI/NAAMM MBG 531 或者 BS 4592 ensures structural integrity under defined loads.

4. Surface Types

• Plain Surface:
  • Smooth and clean, suitable for indoor or low-risk environments.
• Serrated Surface:
  • Serrated bearing bars enhance grip and safety in wet, oily, or hazardous conditions.

5. Finishes

• Hot-Dip Galvanized:
  • Provides a zinc coating for rust resistance, ideal for outdoor or corrosive environments.
• Painted or Powder-Coated:
  • Enhances appearance and adds a layer of protection.
• Untreated:
  • Often used when additional coatings will be applied after installation.

Manufacturing and Construction

1. Fabrication Methods

• Welded Grating:
  • Bearing bars and crossbars are welded at intersections, creating a strong and rigid structure.
• Press-Locked Grating:
  • Bars are mechanically pressed together without welding, offering a smoother surface and clean appearance.
• 铆接格栅:
  • Crossbars are riveted to bearing bars, providing exceptional strength for heavy loads.

2. Types of Heavy-Duty Steel Grating

• Standard Rectangular Grating:
  • The most common, with rectangular openings.
• Heavy-Duty Steel Plate Grating:
  • Uses thicker and deeper bars for extreme load requirements.
• Trench Grates and Covers:
  • Designed for drainage systems, capable of bearing heavy vehicular loads.

Applications of Heavy-Duty Steel Grating

1. 工业地板:

   • Used in factories, warehouses, and processing plants to support heavy equipment.

2. Bridge Decking:

   • Provides a lightweight yet strong alternative for bridge surfaces, capable of handling vehicle loads.

3. Trench and Drain Covers:

   • Commonly installed in areas requiring drainage with the ability to support vehicular traffic.

4. Loading Docks and Ramps:

   • Ideal for docks where forklifts and other heavy machinery operate.

5. Offshore Platforms:

   • Durable and corrosion-resistant grating for oil rigs and marine environments.

6. Parking Garages:

   • Used for ramp surfaces, ventilation covers, and pedestrian walkways.

7. High-Traffic Walkways and Catwalks:

   • Provides sturdy, non-slip pathways in industrial and commercial settings.

Installation Guidelines

1. Proper Support Structure:

   • Ensure the support beams or frame are capable of bearing the anticipated load.

2. Fastening Methods:

   • Use clips, bolts, or welding to secure the grating to the structure.
   • Avoid loose fittings, which can compromise safety.

3. Alignment and Spacing:

   • Maintain uniform spacing to ensure even load distribution and safety.

4. Inspection and Maintenance:

   • Regularly inspect for signs of wear, corrosion, or loosening fasteners.
