Van Body Modifications: Choosing Between Colour Bond, Eco Panel, and FRP’

April 13, 2026

ANJ Transport Solutions explains van body modifications, comparing Colour Bond, Eco Panel and FRP to help Australian fleets choose the right build.

When planning van body modifications, the choice of panel material significantly impacts your vehicle’s long-term performance. For Australian fleets, the right material influences payload capacity, durability in harsh conditions, thermal efficiency for refrigerated transport, and overall brand presentation on the road. Beyond cost, selecting the appropriate body panel is essential for operational efficiency, compliance, and protecting your investment.

Van Body Modifications: Start With Compliance, Payload, and Purpose

Before choosing between Colour Bond, composite panels, or FRP, it is important to assess how the vehicle will be used and how modifications may affect compliance and payload.

In Australia, vehicle modifications must comply with national and state regulations, including the Australian Design Rules (ADRs). Compliance ensures your vehicle remains safe and legally roadworthy. Modifications also affect payload and fuel efficiency, with heavier materials reducing capacity and lighter options improving profitability.

When planning your build, consider:

Whether the vehicle will carry ambient or temperature-sensitive goods
The operating environment, including coastal exposure or high-impact loading docks
Required insulation levels
Branding and finish expectations
Service and repair accessibility in your operating regions

Strategic planning at this stage ensures your van body modifications support long-term productivity. If you are still exploring configurations, you may find insights in our guide on custom truck body design that maximises productivity.

Colour Bond (COLORBOND® Steel): Tough, Familiar, and Cost-Effective

COLORBOND® steel is a pre-painted product engineered for Australian conditions, known for its durability and corrosion resistance when properly installed. It is a practical choice for general freight and high-use environments due to its structural strength and widespread repair familiarity, helping minimise downtime. While heavier than composite options and not inherently insulated, it remains a cost-effective and reliable solution when payload and thermal performance are not the primary concerns.

Eco Panel Composite Sandwich Panels: Lightweight and Insulation-Friendly

Eco Panel composite sandwich panels are lightweight systems made with outer skins and an insulating core, offering excellent strength-to-weight ratio and thermal performance. Their reduced tare weight improves payload capacity and fuel efficiency, making them ideal for refrigerated and temperature-controlled transport. While they resist corrosion and suit wash-down environments, impact performance and repairs can vary depending on the panel construction.

FRP Panels: Smooth Finish, Hygienic Surfaces, and Dent Resistance

FRP (Fibreglass Reinforced Panel) systems are commonly used in both dry freight and refrigerated applications, combining fibreglass skins with a structural core to deliver durability and a smooth, seamless finish ideal for vehicle wraps and strong on-road branding. They are more resistant to dents than traditional metal skins and offer smooth internal surfaces that are easy to clean, making them well-suited to hygiene-sensitive environments. Although repairs may require specialised techniques and weight can vary by construction, FRP panels remain a popular choice for Australian operators seeking a balance of durability, presentation, and cleanability.
