In scenarios such as chemical workshops, food processing plants, and underground parking lots, FRP Panels (Fiberglass Reinforced Plastic decorative panels) are gradually replacing traditional tiles and metal finishes, thanks to their characteristics of corrosion resistance, impact resistance, and easy cleaning. Moreover, standardized 4x8 Rigid Fiberglass Panels (4x8 feet rigid fiberglass panels) and customized Fiberglass Plate Sheets (fiberglass flat plates) have simplified the construction process through modular design. This article will focus on the core topic of "How Do You Install FRP Panels". From material selection and structural design to construction details, it will systematically analyze the technical specifications and innovative practices of the entire installation process.

1. Material Preparation: Key Steps in Selection and Pretreatment

Matching of Panel Specifications

4x8 Rigid Fiberglass Panels:The standard size (2440mm×1220mm) is suitable for large-area walls. It is recommended that the thickness be ≥3mm to ensure the bending strength (≥50MPa).

Fiberglass Plate Sheet: Custom-cut thin plates (1.5-2.5mm) are suitable for curved or irregular-shaped areas. It is necessary to ensure that the resin content is ≥65% to maintain chemical resistance.

Optimization of Auxiliary Materials

Adhesive: Epoxy resin adhesive (tensile strength ≥15MPa) or polyurethane structural adhesive (curing time ≤30 minutes). Avoid using solvents-containing adhesives, which may cause the panels to swell.

Fasteners: 304 stainless steel self-tapping screws (diameter ≥4mm) with silicone gaskets to prevent electrochemical corrosion.

Surface Pretreatment

The flatness deviation of the base surface should be ≤3mm/2m, the moisture content should be ≤8%, and acetone should be used to clean and remove oil stains. Apply an epoxy primer (dosage 200g/m²) to the concrete wall to enhance adhesion.

2. Installation Process: From Structural Design to Precise Construction

Construction of the Keel Framework

Aluminum alloy keel: The spacing of the main keel is ≤600mm, and the secondary keel forms a 300mm×300mm grid by vertical intersection. Use a laser level to calibrate the flatness (error ≤2mm).

Moisture-proof Treatment: In humid areas (such as food workshops), stick a PVC moisture-proof film (overlapping width ≥100mm) between the keel and the wall.

Cutting and Positioning of Panels

Precise Cutting: Use a diamond saw blade (tooth pitch ≤2mm) for low-speed cutting, and grind the edges to a rounded corner of R≥1mm to avoid stress concentration and cracking.

Pre-drilling Technology: The diameter of the drilled hole should be 2-3mm larger than the diameter of the screw (for example, drill a Φ8-9mm hole for a Φ6mm screw) to reserve space for thermal expansion and contraction.

Multi-layer Composite Installation

Dry Hanging Method: Use T-shaped hangers to snap the panels into the keel groove. This method is suitable for high-temperature workshops (-40℃~120℃), and the width of the expansion joint should be ≥5mm.

Wet Pasting Method: Apply the adhesive in dots (spacing 200mm×200mm), apply a pressure of 0.1MPa and maintain it for 24 hours. This method is suitable for medical cleanrooms with no requirement for seams.

3. Sealing and Reinforcement: Core Technologies for Long-term Protection

Joint Treatment

Fill the gaps between the panels with silicone weatherproof sealant (displacement capacity ≥50%). After scraping the surface flat, stick anti-fouling masking tape, and tear it off after curing to ensure neat edges.

Use special FRP corner lines (R angle ≥10mm) at the inside and outside corners, and inject structural adhesive inside to enhance impact resistance.

Edge Closing

Use U-shaped stainless steel edging around doors and windows, embed EPDM rubber strips to achieve airtightness, and the screw spacing should be ≤150mm.

Install PVC baseboards (height ≥100mm) at the junction with the ground, and embed an antibacterial coating inside to prevent mildew.

4. Quality Control and Safety Specifications

Acceptance Standards

Flatness: Use a 2m straightedge to detect that the gap is ≤2mm, and the deviation of the entire wall is ≤5mm.

Bonding Strength: The pull-off test result should be ≥0.8MPa, and there should be no hollowing or delamination.

Safety Protection

Wear an N95 mask and goggles during cutting operations. When the installation height is ≥3m, set up a scaffold and fasten a safety belt.

The storage temperature of chemical adhesives should be ≤30℃, and the on-site ventilation rate should be ≥10 times per hour.

Conclusion: Empowered by Technology, Establishing New Standards of Industrial Aesthetics

From the treatment of the base surface to the closing details, the installation of FRP Panels is not only a functional engineering practice but also an innovative integration of industrial aesthetics and material science. Standardized 4x8 Rigid Fiberglass Panels and flexible Fiberglass Plate Sheets are providing solutions that combine safety and aesthetics for industries such as chemical engineering, healthcare, and food through a scientific construction system.
