Engineered for Australian Conditions. Built to Last.

Versatile Frame Kits for Every Purpose

Your project’s success starts with a strong foundation. Every frame in our range, from the practical Starter to the reinforced Premium, is built from commercial-grade, hot-dipped galvanised steel designed to withstand Australian conditions. Whether you’re creating a polytunnel, shade house, net house, or DIY shelter, our kits are adaptable to slopes, simple to assemble, and built to last. More than just a frame, it’s a long-term investment in a structure you can rely on season after season.

Why choose our MADI products?

We have designed our MADI (modular, adjustable, durable, innovation) products and kits to solve the real-world challenges that Australian growers face, delivering a system that is strong, adaptable, and remarkably convenient.

Optimised Plant Protection: Our kits are complete with high-quality covers; reducing sun intensity, preventing scorch, lowering ambient temperature, and protecting your plants from hail and pests. This creates a stable microclimate for healthier growth and higher yields.
Built for Australian Terrain: The landscape is rarely perfect. Our frames are intelligently designed to adapt, accommodating a slope of up to 1 metre on the width and virtually any gradient along the length, ensuring a secure fit on your property.
Superior Durability & Strength: We use high-grade, hot-dipped galvanised steel (from 32mm to 42mm) for exceptional corrosion resistance and a long service life. The entire structure is assembled with bolts, nuts, and screws, eliminating weak weld points and creating a rigid, resilient frame.
Unbeatable Convenience & DIY-Friendly Design: We've made logistics and assembly effortless with our intuitive flat-pack system.
Easy Transport: No single component is longer than 2.4 metres, allowing the entire kit to fit easily in a standard ute or truck.
Manageable Handling: Every part is packed in individual boxes, each weighing no more than 25-30kg, for safe and easy handling.
Hassle-Free Door-to-Door Delivery: For the ultimate convenience, we offer an optional delivery service that brings most kits directly from our warehouse to your property, saving you time and effort.
