As a specialized factory supplier of double layer roof sheet making machines, we provide complete turnkey production equipment that enables roofing sheet manufacturers to produce both corrugated wave and IBR trapezoidal roof sheets from a single integrated machine platform. Our double layer machines house two independent roller forming decks within one heavy welded structural steel frame — the lower deck configured for traditional corrugated roof sheet production and the upper deck tooled for IBR roof sheet production. We supply the complete production line package including hydraulic decoiler, entry guide station, main double layer forming unit with flying hydraulic post-cut shear, PLC digital control system, and discharge roller conveyor. Every machine undergoes rigorous three-phase factory testing before export packaging to ensure reliable performance from day one of production at your facility.
