Product Parameters

 

When selecting FRP (Fiberglass Reinforced Plastic) Grating, several key parameters determine its suitability for specific applications. Below are the primary parameters to consider:

1. Panel Size and Thickness:

• Panel Size: FRP grating is typically available in standard sizes (e.g., 4x12 ft or 3x10 ft), but custom sizes can be manufactured.
• Thickness: Common thicknesses are 1 inch, 1.5 inches, and 2 inches, which influence the grating's load-bearing capacity and strength.

2. Mesh Size (Opening Size):

• Mesh or Grid Pattern: The open space between bearing bars. Typical patterns include square, rectangular, or custom configurations.
• Open Area Percentage: This refers to the percentage of the panel that is open (non-solid), affecting factors like drainage, ventilation, and the amount of light passing through.
  • Common mesh sizes include 38mm x 38mm (1.5"x1.5") for general use, or smaller mesh (e.g., 19mm x 19mm) for enhanced safety or minimal deflection.

3. Load Capacity (Deflection Limits):

• Load Rating: Grating should be selected based on its ability to carry uniform and concentrated loads. Different grating thicknesses and configurations offer different load-bearing capacities (e.g., 500 lbs per square foot).
• Deflection: Measured in terms of how much the grating flexes under load, typically limited to 1/4" or 1/2" over a span of the grating.

4. Resin Type:

• The resin matrix in FRP grating determines its chemical and environmental resistance. Common resin types include:
  • Isophthalic Polyester Resin: Good general-purpose resin with moderate chemical resistance. Suitable for industrial environments.
  • Vinyl Ester Resin: Offers superior chemical resistance, especially in highly corrosive environments.
  • Orthophthalic Polyester Resin: Standard resin for general use, offering moderate corrosion resistance.
  • Phenolic Resin: Flame-retardant and low-smoke emission, ideal for offshore, marine, and tunnel applications.

5. Fire Rating and Flame Spread:

• FRP grating can be designed to meet fire safety standards. A key parameter is the flame spread rating (typically measured by ASTM E-84 standards). A low flame spread rating (e.g., below 25) is desirable for areas requiring fire retardant materials.

6. Surface Type:

• Gritted Surface: Provides a non-slip surface for enhanced safety, especially in wet or oily conditions.
• Smooth Surface: Easier to clean but offers less traction.
• Concave Surface: Offers some grip without the aggressiveness of gritted surfaces.

7. Span and Deflection Requirements:

• The span between supports determines the required load-bearing capacity. A longer span will require thicker or more robust FRP grating to minimize deflection.
• Deflection limits are typically defined as a percentage of the span length (e.g., deflection ≤ L/100 or L/200, where L is the span).

8. Environmental Factors:

• Corrosion Resistance: The selected resin and design must withstand environmental factors like exposure to chemicals, saltwater, and UV radiation.
• UV Resistance: If the grating is used outdoors, UV stabilizers or protective coatings may be required to prevent degradation over time.

9. Electrical and Thermal Properties:

• Electrical Conductivity: FRP grating is typically non-conductive, making it suitable for applications near electrical equipment.
• Thermal Expansion: FRP has a low thermal expansion coefficient, but it's still important to account for temperature changes in the operating environment.

10. Weight and Density:

• Weight: FRP grating is much lighter than steel or aluminum, with weights ranging between 2 to 5 lbs per square foot depending on thickness and density.
• Density: Affects the overall mass and ease of handling. Lower density gratings are easier to transport and install.

11. Color:

• Standard colors include gray, green, yellow, and beige, though custom colors can be manufactured. Color can also serve functional purposes, such as improving visibility in safety applications.

12. Compliance and Standards:

• ANSI/ASME standards or ASTM D635 testing for flame spread and mechanical properties.
• ASTM E-84: Flame spread classification.
• ASTM D-256: Impact resistance.

By considering these parameters, you can select the appropriate FRP grating for your specific application and environmental needs.

Installation Instructions

 

Installing FRP (Fiberglass Reinforced Plastic) Grating requires careful planning and proper execution to ensure safety, functionality, and durability. Below are general steps and guidelines for installing FRP grating in various applications:

Tools and Materials Needed:

• FRP Grating panels
• Grating clips (M-type, C-type, or G-type clips)
• Stainless steel or corrosion-resistant fasteners (nuts, bolts, washers)
• Measuring tape
• Saw with diamond-coated or carbide-tipped blade (for cutting FRP)
• Drill and drill bits
• Level
• Chalk line (for layout)
• Personal protective equipment (PPE), including gloves, goggles, and dust mask

Installation Steps:

1. Site Preparation:

• Ensure a clean and stable surface: The installation surface (e.g., steel, concrete, or other support structure) should be clean, level, and stable. Remove any debris, dust, or obstructions.
• Check for proper drainage: Ensure the area where the grating will be installed has adequate drainage to avoid standing water or excessive moisture accumulation.

2. Measure and Layout:

• Measure the area where the FRP grating will be installed and verify the required panel sizes. Use a tape measure and chalk line to mark the installation area.
• Ensure correct spacing between supports: Support spans should be based on the load requirements of the application and the grating's structural properties. Refer to manufacturer span tables for appropriate support spacing (e.g., every 24-48 inches depending on the thickness and load rating of the grating).
• Verify clearances: Ensure proper clearances are maintained, especially near walls or obstacles, for easy expansion and movement (e.g., leave a gap of around 1/4 inch).

3. Cutting FRP Grating (if necessary):

• Measure and mark the cut lines: If the grating panels need to be resized, measure carefully and mark cut lines using a straight edge or chalk.
• Use proper tools for cutting: Cut the grating with a saw equipped with a diamond-coated or carbide-tipped blade designed for fiberglass materials. When cutting, ensure the grating is adequately supported to prevent damage or cracking.
• Smooth the edges: After cutting, file down sharp edges to smoothen the cut area and prevent injury or damage during installation.

4. Position the FRP Grating Panels:

• Place the panels onto the support structure: Position the FRP grating panels over the support beams or framework. Ensure the grating spans the distance between supports without excessive overhang (typically not more than 6 inches).
• Align the panels: Align the grating with the support structure, making sure the openings or mesh pattern matches up, especially if multiple panels will be joined together.

5. Secure the Grating Panels with Clips:

• Grating clips: Use grating clips (M-clips, C-clips, G-clips) to anchor the grating panels to the support structure. These clips prevent movement and provide stability.
• Position the clips: Place the clips at the panel edges and where the grating crosses over the support beams. For proper fastening, it's recommended to use 4 clips per panel (2 on each side), with additional clips for larger panels or high-load areas.
• Fasten the clips: Secure the clips with corrosion-resistant fasteners (stainless steel bolts, washers, and nuts). Tighten the bolts using a wrench to secure the grating but avoid overtightening, which could damage the fiberglass.
• Ensure proper spacing of clips: Typically, clips are spaced every 12 to 24 inches along the panel edges and midpoints for even load distribution.

6. Join Multiple Panels (if applicable):

• Align adjacent panels: When joining multiple FRP grating panels, ensure the mesh patterns are aligned for a uniform appearance. Maintain a small expansion gap (around 1/4 inch) between panels to accommodate temperature changes and expansion.
• Secure with clips: Use additional grating clips along the adjoining edges of the panels to keep them tightly aligned and securely fastened to the support structure.

7. Check Alignment and Stability:

• Level the grating: Use a level to ensure that the installed FRP grating is level and properly aligned. Adjust as needed to maintain even load distribution across the surface.
• Verify clip tightness: Double-check all fasteners and grating clips to ensure they are securely fastened, but not over-tightened.

8. Final Inspection:

• Check for sharp edges: After installation, check the panel edges and areas where cuts were made to ensure no sharp fiberglass edges are exposed. If necessary, file down rough spots and apply a resin coat to seal any cut edges.
• Ensure proper drainage: Verify that there are no blockages or areas where water could pool. Proper drainage should occur through the grating's openings.
• Conduct a load test: If necessary, test the grating by applying load (e.g., walking on it or placing equipment on it) to ensure stability and proper support.

9. Post-Installation Maintenance:

• Regular inspections: Periodically check the installation for signs of wear, damage, or loose clips. Ensure that any chemical spills or debris are cleaned to maintain the integrity of the FRP grating.
• Clip tightening: Over time, clips may loosen due to vibrations or thermal expansion, so check them periodically and re-tighten if necessary.

By following these instructions and adhering to manufacturer guidelines, you can ensure a durable, safe, and effective installation of FRP grating for a variety of industrial, commercial, or residential applications.
