Why choose a JMac set of trailers?

🦾 Our bowls and chassis are both made from structural grade materials

🦾 Steel bowls: Hardox 450
🦾 Aluminium bowls: T5 Aluminium, 5083 grade

🎨 Bowls and chassis completely blasted and painted
🎨 Inside and out
🎨 Anti corrosion
🎨 By the legends at Wandering Smash Repairs

🔬 Thoughtfully designed locally in collaboration with more legends at Pingelly Transport and other drivers

⚖️ Designed with weight at the forefront of mind, with competitive tare weights and capacity

🛠️ Built by a local workforce, where you know the whole teams names

💰 We understand a set of trailers is an investment to have in your fleet for many years to come, not a disposable
