Custom Fiberglass Vehicle Body Parts for Heavy Equipment, Buses and Commercial Vehicles
DISLAB manufactures custom fiberglass vehicle body parts for demanding transport and industrial applications, including bus roof covers, FRP body panels, truck fenders, heavy equipment covers, access doors, and molded composite housings. Our SMC and FRP components are engineered to replace heavy metal parts with lighter, corrosion-resistant, and production-ready alternatives.
We support OEM buyers, fleet operators, aftermarket distributors, and industrial project teams that need stable quality, engineering communication, and export-ready delivery.
Why Buyers Replace Metal Parts with Fiberglass Vehicle Body Parts
Traditional steel panels and covers increase vehicle weight, corrode in humid or coastal environments, and create ongoing repainting and maintenance costs. Fiberglass composite body parts solve these issues at the material level while allowing more flexible molding for OEM and retrofit applications.

Case Study: Custom Fiberglass Bus Roof Covers for a Peruvian Public Transport Client
Project Background and Requirements
The client was upgrading part of its city bus fleet and needed custom fiberglass roof covers to replace heavier metal components. The project required reliable performance in Peru’s coastal environment, compliance with local transport safety expectations, and full delivery within 45 days to match the client’s fleet maintenance and renewal schedule.
- Climate adaptation: High humidity, salt-laden coastal air, and strong UV exposure required excellent corrosion resistance and weather stability.
- Safety and structural requirements: The covers needed impact resistance and fire-retardant properties appropriate for public transport applications.
- Fast production timeline: The complete order had to be delivered within 45 days.
- Weight reduction: The new fiberglass covers needed to be significantly lighter than the original metal parts to help improve fuel efficiency.
Our Solution and Execution
1. Technical Review and Material Selection
Our engineering team reviewed the customer’s drawings, installation requirements, and environmental conditions. We selected a UV-stabilized, fire-retardant fiberglass composite system and optimized the structure to meet both strength and weight targets. The final design reduced part weight by 32% compared with the original metal version.
2. Prototype Approval and Testing
We produced 5 first-article samples for fit, finish, and performance verification. The prototypes underwent in-house validation including UV aging simulation, salt spray corrosion testing, impact resistance checks, and fire-retardant testing aligned with project requirements. All samples passed and were approved by the client.
3. Batch Production and Quality Control
After approval, we moved into mass production with a defined QC workflow. All 500 units went through dimensional inspection, surface finish checks, material verification, and final performance sampling. We also provided weekly production updates to maintain project visibility for the customer.
4. Packaging and Export Delivery
The finished parts were packed in export-grade, moisture-resistant crates for sea shipment to Callao Port, Peru. The full order was completed and delivered on schedule, ahead of the client’s required deadline.
Client Outcome
- Excellent durability in coastal service conditions, with no reported corrosion or visible fading.
- Improved fuel efficiency due to lower component weight.
- Positive feedback on engineering support, production consistency, and on-time delivery.
- Follow-up order placed for an additional 300 units for the client’s 2026 fleet expansion.
