TP02 Custom Fiberglass Truck Fender for OEM Body Kits

This fiberglass truck fender is developed for vehicle body applications that require a formed wheel-arch structure, defined outer contours, and flexible finishing options. The product images show a smooth molded panel with a large wheel opening, shaped edges, and integrated mounting locations.

The fender can be used as an individual replacement component or as part of a broader fiberglass truck body kit. Depending on the vehicle design, related components may include front bumpers, rear bumpers, engine hoods, air deflectors, interior parts, and other FRP body panels.

The primary product focus remains the truck fender. Other truck body parts can be developed as separate components within the same OEM or ODM project.

Molded Wheel-Arch Profile

The curved wheel opening is formed to follow the tire and wheel area of the vehicle. This allows the fender to provide a clean body contour while leaving the required clearance for wheel movement.

The final wheel-arch dimensions, edge shape, mounting points, and panel depth should be developed according to the target truck, chassis, cab structure, and installation method.

Smooth Outer Surface

The sample shown has a smooth black surface with a clean molded appearance. The surface can be further developed with gel coat, glossy finishing, matte finishing, or painting according to the required appearance and downstream installation process.

A suitable surface treatment can help the fender match the vehicle body, support branding requirements, or prepare the part for additional painting and assembly.

Custom Body-Part Development

The fender can be developed from existing samples, product images, vehicle measurements, molds, or 2D and 3D drawings. For a new body-kit project, the design team can review the geometry, mounting requirements, material selection, production process, and finishing requirements before sampling.

Product Features and Construction

Lightweight Fiberglass Composite Structure

Fiberglass-reinforced plastic provides a molded composite structure suitable for truck body panels and exterior components. Compared with conventional metal body parts, the final weight depends on the laminate design, wall thickness, reinforcement layout, and selected production process.

The product page lists a reference density of 1.6–1.7 g/cm³. The final density should be evaluated together with the required strength, stiffness, impact conditions, mounting method, and vehicle application.

Thin-Wall Design

The product information lists a wall thickness of at least 1.0 mm. Actual wall thickness may vary across different areas of the fender because wheel-arch curvature, edges, mounting points, and reinforcement zones may require different structural treatment.

For OEM projects, the wall thickness should be defined in the approved drawing or technical specification rather than applied uniformly to every area of the part.

High-Strength FRP Material

The product page lists a tensile-strength reference of at least 220 MPa. Final mechanical performance depends on the fiberglass type, resin system, fiber orientation, laminate thickness, curing process, and test method.

When the truck fender is used in a demanding commercial or heavy-duty application, material and structural requirements should be evaluated together with the vehicle body design.

Formed Mounting Areas

The product images show mounting openings and shaped edges designed for installation. These areas can be adapted to match the target vehicle or existing body structure.

Mounting-point accuracy is important because incorrect hole positions may affect installation time, panel alignment, fastening, and the relationship between the fender and adjacent body parts.

Water and Weather Exposure

Truck fenders are exposed to rain, road splash, dust, sunlight, and changes in temperature. The selected resin system, surface finish, sealing method, and mounting design should match the expected operating environment.

The product page lists IP68 sealing performance for the product reference. Any waterproof or sealing claim for a finished truck fender should be linked to the actual part design, sealing construction, and applicable test report.

Fiberglass Truck Fender Specifications

The listed product values provide a technical starting point for development. Final specifications should be established according to the approved drawing, selected material system, production process, vehicle application, and inspection requirements.

Manufacturing Processes for Fiberglass Truck Fenders

Different truck fender projects may require different molding methods. The most suitable process depends on the part size, geometry, production volume, surface requirements, and expected investment in tooling.

Hand Lay-Up

Hand lay-up is suitable for prototypes, custom parts, low-volume programs, and products that require flexible structural adjustments. Fiberglass reinforcement is positioned manually in the mold and impregnated with resin before curing.

This method is useful when a project requires design flexibility or when the initial production quantity does not justify a more automated process.

Vacuum Infusion

Vacuum infusion uses vacuum pressure to draw resin through the reinforcement material. The process can help improve resin distribution and reduce excess resin in suitable part designs.

It may be considered for larger panels or projects where laminate consistency and weight control are important.

Resin Transfer Molding

RTM uses a closed mold into which resin is injected around a prepared fiber reinforcement. It can provide a more controlled molding environment and support parts with defined surfaces on both sides.

RTM may be suitable for repeat production where dimensional consistency, appearance, and production repeatability are important.

SMC Molding

Sheet molding compound is suitable for certain production programs requiring compression molding and repeatable part output. The final suitability depends on the geometry, material requirements, tooling design, and production volume.

XHY’s composite manufacturing technology covers multiple production processes, allowing the manufacturing method to be evaluated around the actual project rather than selected only by product name.

Surface Finishing and Appearance Options

The surface finish affects both the appearance and the downstream use of a fiberglass truck fender.

Gel Coat Finish

Gel coat can provide a colored and smooth outer surface while forming part of the protective surface system. It can be selected when the customer requires a molded appearance without immediate painting.

Glossy Finish

A glossy finish can be used for truck body parts that need a smooth, reflective appearance. Surface preparation, mold condition, and post-molding treatment can all affect the final result.

Matte Finish

A matte finish may be preferred for utility vehicles, fleet equipment, industrial applications, or projects where a lower-reflection appearance is required.

Painted Finish

Painting allows the fender to match the truck body or a fleet color system. The paint specification should consider the selected gel coat, surface preparation, coating compatibility, and expected outdoor exposure.

RAL Color Matching

RAL colors can be used as a reference for custom color development. Final color evaluation should be based on an approved sample under agreed lighting conditions.

Vehicle Fitment and Application

A fiberglass truck fender should not be described as universally compatible unless the design has been developed and tested for a defined group of vehicles.

Commercial Trucks

The fender can be developed for commercial truck body projects where a shaped fiberglass replacement or new body panel is required.

Heavy-Duty Vehicles

Heavy-duty vehicles may require additional attention to panel size, mounting strength, road vibration, surface exposure, and adjacent body components.

Bus and Engineering Vehicles

The product page lists buses and engineering vehicles among its application areas. For these projects, the fender design should be based on actual vehicle dimensions, wheel clearance, mounting structure, and operating conditions.

RV and Special Vehicles

Fiberglass body panels are also used in RV and other special-vehicle projects. These applications may involve low-volume customization, new molds, or modifications to an existing design.

Vehicle-Specific Development

For accurate fitment, buyers should provide:

• Vehicle make and model

• Chassis or platform information

• Production year

• Wheel and tire dimensions

• Existing part or sample

• Installation drawings

• Mounting-point information

• Required clearance

• Expected order quantity

This information allows the fender to be developed around the actual installation requirements.

OEM and ODM Customization Process

XHY FRP supports a structured custom-development process for fiberglass truck body parts.

Step 1: Submit the Product Brief

Customers can provide product pictures, existing parts, molds, technical requirements, or a description of the intended application.

The initial brief should explain whether the project is for replacement parts, a new body kit, fleet production, vehicle modification, or an aftermarket program.

Step 2: Provide Drawings and Measurements

2D drawings, 3D files, vehicle measurements, and installation references help define the part geometry.

If a complete drawing is not available, an existing sample or physical part may be used as the starting point for reverse engineering and design development.

Step 3: Confirm Material and Process

The material may be fiberglass composite, carbon fiber, or another specified composite system. The molding process can then be selected according to the part structure, quantity, surface, and performance requirements.

Step 4: Confirm Surface Treatment

Customers can specify gel coat, gloss, matte, painting, color matching, or other surface requirements. The surface treatment should be compatible with the selected material and intended installation process.

Step 5: Review the Final Drawing

Before mold production and sampling, the design solution and final drawing should be reviewed. Important details include wheel-arch dimensions, panel edges, mounting holes, thickness, reinforcement zones, and adjacent-part interfaces.

Step 6: Approve the Sample

The first sample can be checked against the vehicle, existing part, or agreed test method. Fitment, surface quality, mounting position, panel alignment, and appearance should be reviewed before mass production.

Step 7: Move to Production

After the sample and technical details are approved, production can proceed according to the agreed material, process, finish, packaging, and inspection requirements.

The XHY customization process is based on customer drawings, material requirements, surface treatment, design approval, sampling, and subsequent production.

Quality Control for Fiberglass Truck Fenders

Dimensional Inspection
