1. Material

• Type of Metal:

  • Carbon Steel (Mild Steel)
  • Stainless Steel (e.g., SS304, SS316 for corrosion resistance)
  • Aluminum (lightweight applications)
  • Galvanized Steel (corrosion-resistant coating)
  • Other alloys (e.g., brass or titanium for specialized uses)

• Surface Treatment:

  • Hot-dip Galvanized
  • Powder Coated
  • Anodized (for aluminum)
  • Plain (Untreated raw metal)

2. Grating Type

• Bar Grating:

  • Welded Grating: Bars are welded at intersections for durability.
  • Press-Locked Grating: Pressure locks bars together for a smooth finish.
  • Swage-Locked Grating: Mechanically locked for precision and strength.

• Expanded Metal Grating:

  • Metal sheet cut and expanded into a diamond mesh pattern.

• Perforated Grating:

  • Grates with custom-shaped holes punched into a metal sheet.

• Riveted Grating:

  • Riveted connections for heavy-duty, high-strength applications.

3. Dimensions

• Panel Size: Length × Width (e.g., 1,000 mm × 500 mm or as per project requirements).
• Bar Size (Load Bar Dimensions): Width × Thickness (e.g., 30 mm × 5 mm).
• Cross Bar Size: Diameter or width (e.g., 6 mm round bar).

4. Load and Spacing

• Load Bar Spacing:

  • Distance between parallel load-bearing bars (e.g., 30 mm, 40 mm, or 60 mm).

• Cross Bar Spacing:

  • Distance between crossbars or transverse elements (e.g., 50 mm or 100 mm).

• Load Capacity:

  • Uniform Load Rating (e.g., kN/m²).
  • Point Load Rating (e.g., kN).

5. Thickness

• Load Bar Thickness: Typically ranges from 3 mm to 10 mm or more, depending on strength needs.
• Cross Bar Thickness: Generally smaller than load bars, e.g., 6 mm.

6. Surface Design

• Texture:

  • Smooth Surface: For low-traction or aesthetic purposes.
  • Serrated Surface: For slip resistance in wet or hazardous environments.

• Coating:

  • Anti-slip coatings (e.g., epoxy-based).
  • Galvanized or painted for protection.

7. Pattern and Openings

• Standard Patterns:

  • Rectangular (e.g., 30 × 100 mm or 40 × 100 mm).
  • Square (e.g., 50 × 50 mm).
  • Diamond (for expanded metal grating).

• Custom Patterns: Tailored for decorative or application-specific needs.

8. Weight

• Weight per Unit Area: Typically measured in kilograms per square meter (kg/m²).

9. Compliance and Standards

• Safety and Structural Standards:

  • ISO 14122 for walkways and working platforms.
  • ASTM Standards (e.g., ASTM A36 for mild steel).
  • EN Standards (e.g., EN 1090 for steel structures).

• Load Testing: Compliance with design loads and deflection limits for structural safety.

10. Applications

• Industrial Uses:

  • Platforms, walkways, trench covers, and machine enclosures.

• Commercial Uses:

  • Flooring, facades, entrance mats, and stair treads.

• Public Infrastructure:

  • Drain covers, pedestrian walkways, and stormwater systems.

• Architectural Applications:

  • Decorative panels, sunshades, and ventilation covers.

11. Environmental Resistance

• Corrosion Resistance:

  • Stainless steel or galvanized metal for outdoor and marine applications.

• Heat Resistance:

  • High-performance alloys for extreme temperatures.

12. Customization Options

• Grating can be fabricated to meet specific requirements for shape, size, strength, or aesthetic design.
