DuoShield Metal Skin Reefers are built for transporters who need structural strength and long-term durability without compromising cooling performance. Built using Sub Zero's DuoShield panel technology, these reefers feature metal skins on both sides - an external layer of PPGI (Pre-Painted Galvanised Iron) and an internal layer of food-safe plastisol-coated steel - with a rigid insulated core in between.
Whether carrying pharmaceuticals, frozen foods, or sensitive perishables, DuoShield Metal Skin Reefers maintain consistent temperature profiles through long hauls, loading delays, and unpredictable weather. They integrate seamlessly across mixed fleets, including reefer trucks, refrigerated containers, reefer vans, and reefer trailers.
The metal skins in the DuoShield construction act as a continuous vapour barrier, preventing moisture ingress and protecting the insulation over time. This ensures the box does not absorb any moisture and that thermal efficiency remains consistent throughout its service life.
For operators running high-duty refrigerated transport, DuoShield Metal Skin Reefers deliver dependable performance run after run—making every journey more efficient and every load more secure.
AluFlow is Sub Zero's advanced aluminium extrusion flooring system engineered for strength, hygiene, and efficient airflow inside refrigerated bodies. The floor is constructed using precision aluminium extrusions with a corrugated profile that allows air to circulate freely beneath the cargo, supporting uniform temperature distribution.
The aluminium extrusions interlock along the length of the box, creating a continuous, rigid floor structure. At the periphery, the flooring connects with the kick plates and is fully welded, forming a sealed and leak-proof floor assembly.
The kick plates themselves are fixed to the side walls, ensuring a strong mechanical connection between the floor and the box structure. This integrated construction prevents water ingress, eliminates weak joints, and significantly improves overall box rigidity.
The result is a durable, hygienic, and easy-to-clean floor system that maintains thermal performance while withstanding demanding operating conditions in refrigerated transport.
German-backed engineering tailored for Indian logistics

A metal skin reefer box is an insulated cargo body made with durable metal panels designed to maintain a controlled temperature during transport. It is commonly used on a reefer truck or reefer refrigerated truck for carrying perishable goods safely.
PPGI stands for Pre-Painted Galvanized Iron. It is a corrosion-resistant, durable metal used in reefer truck body construction, offering better weather resistance, lower maintenance, and a clean finish.
The DuoShield reefer body supports temperatures from –25°C to +25°C, depending on the refrigeration unit installed. It is suitable for use with electric reefers, helping transport frozen, chilled, and temperature-sensitive products.
The DuoShield reefer body is compatible with a wide range of light and medium commercial vehicle chassis, making it suitable for different reefer truck applications, including electric refrigerated van conversions.
DuoShield is Sub Zero's PPGI (Pre-Painted Galvanized Iron) reefer body. Compared to a traditional GRP reefer body, DuoShield features a stronger metal exterior that offers excellent durability, easier repairs, and better resistance to dents and everyday wear, while providing reliable insulation and temperature control for cold chain transportation.
The payload capacity depends on the vehicle chassis and body size. DuoShield's lightweight design helps maximize payload while maintaining the insulation needed for efficient reefer refrigerated truck operations.
Yes. The DuoShield reefer body can be fitted with a tail lift, making loading and unloading faster and safer for reefer truck deliveries, especially in urban and last-mile cold chain operations.
The cost of a metal skin reefer body depends on factors such as the vehicle chassis, body size, insulation specifications, and the refrigeration unit selected. In general, the reefer body itself starts from around ₹3 lakh for smaller commercial vehicles and can go up to ₹10 lakh or more for larger configurations. The total cost of a complete reefer truck, including the chassis and refrigeration unit, varies based on your operational requirements. For an accurate quotation, it's best to choose a configuration based on your payload, temperature range, and application.
DuoShield metal skin reefer bodies can be mounted on a wide range of light commercial vehicles (LCVs) and medium commercial vehicles (MCVs), depending on your payload, body size, and application. Smaller chassis are ideal for last-mile deliveries of dairy, pharmaceuticals, and fresh produce, while larger chassis are better suited for bulk cold chain transport over longer distances. The right chassis should be selected based on the cargo volume, temperature requirements, and operational route.
