A good ute is only as useful as the tray on the back. Whether you’re hauling tools to a job site, fencing gear on the farm, or loading up for a weekend mission, a flatdeck tray gives you space, strength, and flexibility. We build flatdeck ute trays that are designed and made right here in New Zealand - tough enough for hard work and smart enough for everyday life.
What is a Flatdeck Tray?
A flatdeck or ute tray is a custom-built, open cargo area designed for utility vehicles. Unlike traditional wellside trays, flatdecks offer a flat, open surface without wheel arches, providing more usable space for transporting tools, equipment, or gear.
Flatdeck trays are all about usable space. With no wheel arches or high sides, you get a wider, more open deck that makes loading and unloading fast and easy. Long timber, bulky tools, or awkward equipment fit without a struggle. Internal tie-down points keep everything secure, and a flush rear coaming makes cleaning quick.
For tradies, a flatdeck is a mobile workspace. Farmers love the ability to carry posts, feed, or stock gear safely. Outdoor enthusiasts enjoy the versatility for gear, kayaks, or weekend adventures. Add in options like drawers, under-tray boxes, and headboards, and you have a setup that works for your lifestyle and your job.

Advantages of Flatdeck Trays
1. Increased Usable Space
Flatdeck trays eliminate wheel arches and high sides, offering a wider and longer cargo area. This design allows for the transportation of larger or bulkier items that might not fit in a standard wellside tray.
2. Enhanced Durability
Many flatdeck trays are constructed from heavy-duty materials like 3mm steel or aluminium, making them robust and capable of handling tough New Zealand conditions. For instance, some models are load-tested to 700kg, ensuring they can withstand heavy use.
3. Customization Options
Flatdecks can be tailored to specific needs with features like lockable under-tray boxes, drawers, tie-down points, and headboards. This customization ensures that the tray suits the user's specific requirements, whether for work or recreation.
4. Easy Loading and Unloading
The open design of flatdeck trays facilitates straightforward loading and unloading of items, especially when dealing with large or awkwardly shaped equipment.
5. Improved Safety Features
Some flatdeck trays come equipped with reinforced headboards and integrated tie rails, enhancing safety during transport and reducing the risk of cargo shifting.

Disadvantages to Consider
1. Exposure to Elements
Unlike wellside trays with covers, flatdecks are open to the elements. While this design offers more space, it also means that items are more exposed to weather conditions, potentially leading to rust or weathering over time.
2. Potential for Increased Wind Resistance
The open sides of a flatdeck tray can create additional wind resistance, which might slightly affect fuel efficiency, especially at higher speeds.
3. Security Concerns
Without proper lockable storage solutions, items on a flatdeck tray can be more susceptible to theft. It's essential to invest in secure storage options to mitigate this risk.
4. Aesthetic Considerations
Some individuals might prefer the enclosed look of a wellside tray. Flatdecks have a more utilitarian appearance, which might not appeal to everyone.
