With growing demand for lightweight and durable commercial vehicle bodies, fiberglass skin PET foam core composite panels are increasingly used in the construction of dry van truck bodies, especially for swing doors where weight reduction, strength, and long-term reliability are critical.
Material Introduction
The combination of FRP (fiberglass reinforced plastic) sheets and PET (polyethylene terephthalate) foam is a mature composite structural solution developed through long-term experimentation and application verification. This structure balances lightweight, high strength, and stable performance, providing a reliable material foundation for modern van doors. Compared to traditional metal or plywood doors, PET foam composite doors offer significant performance advantages.
Material Advantages
☑Lightweight
Reducing door weight helps lower the overall vehicle weight, thereby improving payload efficiency and fuel economy.
☑ Durable
The composite structure offers excellent impact resistance and a long service life under harsh transportation conditions.
☑ Waterproof and Mildew-proof
The non-absorbent material prevents moisture penetration, corrosion, and mold growth.
☑ Easy to Process and Cut
PET foam sandwich panels can be efficiently processed and customized to various door structures.
How to Choose a Sealing Method?
High-performance flexible sealing gaskets provide weather resistance and create a fully light-tight cargo enclosure, while protecting the connection between the doors and body structure.
Option 1: Composite Panels + Sealing Strips
- Application
Suitable for standard light-duty dry van bodies. Offers a simple structure and cost-effective solution for general cargo transportation.
- Features
The sealing strip directly wraps around the PET composite panel.
Option 2: Composite Panels + Aluminum Profiles + Sealing Strips
- Features
Door perimeters are wrapped with high-strength extruded aluminum profiles, providing edge protection, structural reinforcement, and an intelligently integrated sealing interface.
- Applications
Designed for dry van bodies requiring enhanced sealing performance and structural strength. Improves overall rigidity and durability, ideal for mid-to-high-end transport applications.
Further Optimized Swing Door Design
In addition to the advantages of the PET composite panel, our optimized engineering design and precision hardware also greatly improve the door’s operational performance, sealing performance, and structural protection performance.
Reinforced Steel Back Plates
As rear doors are among the most impact-prone areas in traffic incidents, integrated steel reinforcement plates enhance door rigidity and improve resistance to accidental damage.
Heavy Duty Hinges
Multiple heavy-duty hinges ensure smooth operation, long service life, and dependable support under repeated opening cycles.
Flush-Mounted Stainless Steel Door Handles
Door handles with concealed locking rods housed inside the door panel create a cleaner exterior appearance while improving protection and security.
