An Industry Disruptor and Game-changer
HERM Logic is built on four decades of manufacturing, engineering, and B2B excellence. Our story began in 1984 when founder John Müsster launched Müsster Metals, a Just‑in‑Time manufacturer supplying precision components to major Australian industries - Toyota and Besco Batteries in Australia. That commitment to quality, innovation, and operational discipline became the foundation of HERM Logic.
In 2005, we evolved into a specialist consulting firm in sourcing, vendor management, logistics, and supply chain strategy—supporting SMEs and multinational corporations across Australia and New Zealand.
By 2018, John returned to design and manufacturing, creating the first HERM Material Lifter and Conveyor. What began as a single innovation has grown into a multi‑award‑winning rooftop logistics platform that transforms productivity, safety, and cost efficiency across roofing, solar, HVAC, and building services. Through continuous engineering—from Gen1 (Mk1) to the latest Gen3 (Mk3) - HERM Ultra Lite series—we’ve delivered up to 45% in labor cost savings and up to 90% productivity gains for contractors worldwide.
Today, HERM Logic combines advanced FRP engineering, modular lift technology, and compliance‑ready workflows to redefine how materials move from ground to roof. With innovation in our DNA and a global footprint strengthened by our 2024 acquisition of HERM Group Limited (Hong Kong), we remain committed to building safer, smarter, and more profitable job sites for every contractor we serve.
