Fiberglass Reinforced Plastic (FRP) panels are composite materials made by combining a polymer resin with strong glass fibers. This fusion results in a product that inherits the best qualities of both components: the flexibility and corrosion resistance of plastic and the exceptional tensile strength of fiberglass. The "smooth surface" variant refers to a non-porous, glossy finish that is exceptionally easy to clean and resistant to moisture, mold, and bacteria. The classic white color enhances brightness, promotes a sense of cleanliness, and provides a neutral backdrop for any setting.
Available in two primary thicknesses—1.5mm and 2mm—these panels offer options for different structural and budgetary needs. The 4 x 8 frp panel 1.5mm is a lightweight and cost-effective choice for standard wall covering, while the 4 x 8 frp panel 2mm provides added rigidity for areas requiring more impact resistance. The same principle applies to the longer sizes, giving professionals a versatile toolkit for various projects.

Durability and Impact Resistance: The embedded glass fibers give FRP panels remarkable strength. The 2mm thickness panels, like the 4 x 10 frp panel 2mm, are particularly robust, making them ideal for high-traffic areas or places where incidental impact might occur.
Moisture and Mold Resistance: Impervious to water, these panels will not warp, rot, or support mold and mildew growth. This makes them perfect for humid environments such as bathrooms, swimming pool areas, food processing plants, and cold storage facilities.
Easy Cleaning and Maintenance: The non-porous, smooth surface can be wiped clean with standard disinfectants. This hygienic property is indispensable for healthcare facilities, restaurants, and schools.
Chemical Resistance: FRP panels resist a wide range of chemicals, acids, and alkalis, protecting the underlying wall structure in laboratories, factories, and garages.
Lightweight and Easy to Install: Compared to traditional materials like ceramic tile or solid plastic sheets, FRP panels are surprisingly light, simplifying handling and installation on both new and existing walls.
Aesthetic Flexibility: The bright white finish offers a clean, modern look. It can be used as-is for a seamless appearance or easily painted (if using paintable FRP) to match any design scheme.
Our range of smooth surface white FRP panels is designed to meet diverse project requirements. The standard widths are 4 feet, with lengths that accommodate different wall heights and design layouts, minimizing seams and waste.
The 4 x 8 frp panel is the most common and versatile size, fitting standard wall dimensions in many residential and commercial settings. It is easy to transport and handle.
4 x 8 frp panel 1.5mm: This thickness is an excellent all-purpose choice for standard interior wall covering in dry to moderately humid areas. It provides a perfect balance of performance and value.
4 x 8 frp panel 2mm: Offering greater rigidity and durability, this panel is suited for walls that may see more wear and tear, such as in utility rooms, commercial kitchens, or industrial workshops.
For spaces with higher walls or to create longer vertical runs with fewer horizontal seams, the 4 x 10 frp panel is ideal.
4 x 10 frp panel 1.5mm: This panel extends coverage with a lighter-weight profile, perfect for covering larger areas like warehouse offices or retail store walls efficiently.
4 x 10 frp panel 2mm: The extra length combined with 2mm thickness makes the 4 x 10 frp panel 2mm a heavyweight champion for demanding environments that require both large panel coverage and superior strength, such as in agricultural buildings or processing plants.
Maximize vertical coverage and minimize seams with the impressive 4 x 12 frp panel. This size is often used in commercial and industrial buildings with high ceilings.
4 x 12 frp panel 1.5mm: A cost-effective solution for creating seamless, clean walls in large areas like gymnasiums, airport corridors, or supermarket interiors.
4 x 12 frp panel 2mm: When large panel size and maximum durability are non-negotiable, the 4 x 12 frp panel 2mm is the go-to option. Its strength is suited for structural sheathing or in areas prone to physical impact.
4 x 12 frp panel white: The 4 x 12 frp panel white specification emphasizes the clean, reflective quality of this large-format panel, which can dramatically brighten a vast interior space while providing a durable, low-maintenance surface.
The utility of smooth surface white FRP panels spans from simple decorative finishes to critical industrial applications.
This is the most straightforward application. The panels are installed directly onto wall studs or over existing drywall/plywood substrates in:
Commercial Restrooms & Showers: Their waterproof nature makes them perfect for these wet areas.
Restaurant Kitchen Walls: They meet health code requirements for cleanable, non-absorbent surfaces.
Hospital & Clinic Walls: Hygiene and durability are paramount in these settings.
Residential Basements & Laundry Rooms: They protect against moisture and are easy to maintain.
Beyond wall covering, these panels serve as excellent materials for fabricating other items:
Advertising Boards & Signage: The smooth white surface is an ideal blank canvas for direct printing or applying vinyl graphics, creating durable indoor and protected outdoor signs.
Switchgear and Electrical Enclosure Boxes: The electrical insulation properties and chemical resistance of FRP make the 4 x 8 frp panel 2mm or 4 x 10 frp panel 2mm excellent choices for fabricating non-corrosive, durable outer casings for electrical components.
Clean Rooms & Laboratories: The seamless, non-shedding surface maintains sterile environments.
Food Processing & Cold Storage Areas: They withstand constant wash-downs and low temperatures.
One of the most powerful applications is using the FRP sheet as a facing skin for composite or sandwich panels. In this use, a 4 x 12 frp panel white (1.5mm or 2mm) is laminated to both sides of a lightweight core material, such as polystyrene (EPS), polyurethane (PUR), or honeycomb paper.
Result: A rigid, lightweight, and highly insulated partition panel.
Applications: These composite panels are used for quick-construction interior walls, office partitions, clean room walls, and modular buildings. The FRP skin provides the durable, cleanable surface, while the core provides insulation and structural depth.

Proper installation is key to achieving a professional, long-lasting finish. Here is a step-by-step overview of the process.
Tools Required: Tape measure, level, circular saw or jigsaw with a fine-tooth blade, drill, screwdriver, caulking gun, notched trowel, roller.
Materials: FRP panels (e.g., 4 x 8 frp panel 1.5mm), FRP-rated adhesive, FRP panel screws/staples, FRP corner molds and trim, color-matched caulk.
Substrate Preparation: The wall must be sound, dry, and flat. Install over plywood, oriented strand board (OSB), or moisture-resistant drywall. For stud installation, first attach a continuous sheathing of one of these materials. Ensure the surface is free of dust, grease, and protrusions.
Planning & Layout: Start in the least conspicuous corner. Plan your layout to minimize small cuts, especially around doors and windows. Use a level to mark plumb lines.
Cutting the FRP Panels: Measure and mark the panel. Support it firmly and cut with the finished side up using a saw. Always wear safety glasses and a dust mask.
Applying Adhesive: Using a notched trowel, apply a consistent, even layer of FRP-rated adhesive to the back of the panel or directly to the substrate in a section slightly larger than the panel.
Placing the First Panel: Carefully position the first panel (for instance, a 4 x 10 frp panel 2mm) according to your layout lines. Press it firmly into place.
Fastening & Seaming: While the adhesive sets, temporarily secure the panel with FRP screws or staples at the top and bottom. For permanent installation in commercial settings, screws with color-matched heads are often used along the seams and into the studs. Install subsequent panels, leaving a consistent 1/16-inch gap for expansion.
Trimming & Finishing: Install internal and external corner molds for a clean finish. Apply FRP-rated color-matched caulk to all seams, corners, and perimeter joints. Smooth the caulk with a wet finger or tool for a seamless appearance.
Final Cleaning: Once the adhesive and caulk have cured as per manufacturer instructions, wipe down the entire installation with a mild cleaner to remove any residue.
Team Lift: A 4 x 12 frp panel white is large and can be cumbersome. Always use two or more people to move and position it.
Extra Support: Ensure your substrate has ample fastening points, especially in the field (center) of the panel, to prevent bowing or "oil-canning" over time.
Check for Flatness: Larger panels magnify substrate imperfections. Ensure your wall sheathing is perfectly flat before beginning.
