Zhongtuo Roll Forming Machinery is proud to unveil its latest breakthrough in building panel production: the Aluminum Alloy PIR Insulated Great Wall Panel Making Machine. Designed for next-generation wall insulation and energy efficiency, this roll forming line offers a complete solution for producing PIR-core exterior siding panels with seamless visual appeal and superior performance.
Meeting the Demand for Energy-Efficient Construction Materials
With rising global demand for prefabricated structures, energy-efficient buildings, and modern design, this innovative machine enables manufacturers to produce high-quality insulated panels with speed, accuracy, and reduced waste.
The panel features an aluminum alloy exterior skin and a polyisocyanurate (PIR) insulation core, combining lightweight design with thermal resistance. The signature Great Wall aesthetic ensures a modern, seamless finish for exterior walls—without visible fasteners.
Machine Highlights
Zhongtuo’s new production line integrates:
Precision roll forming for upper and lower skins
