Double Layer IBR Roof Sheet Roll Forming Machine | PUTAI, Tianjin, China

PUTAI Double Layer IBR Roof Sheet Roll Forming Machine – Two Roofing Profiles on One Machine

The PUTAI double layer IBR roof sheet roll forming machine combines two roofing profiles in a single machine, with an IBR roller set on one level and a second profile on the other. Roofing sheet producers can switch between products on the same frame, doubling their range without buying, powering or housing a second machine. It forms 0.3–0.7 mm galvanized and pre-painted steel, cuts each sheet to the ordered length with a hydraulic guide pillar cutter, and is controlled by a simple PLC, making it a cost-effective choice for growing roofing businesses.

What Is IBR Roof Sheet?

• IBR stands for Inverted Box Rib, a trapezoidal roofing profile with strong, square-shaped ribs
• One of the most popular roofing sheets in South Africa and across Southern, East and West Africa
• The deep ribs give good strength and span, with fast rainwater run-off
• Used on homes, schools, farms, warehouses and commercial buildings

Why Choose a Double Layer Machine?

• Two products, one machine: Offer customers IBR plus a second profile from the same line
• Lower investment: Less than buying two separate single-layer machines
• Less floor space: One frame instead of two
• One power supply and control system: Lower installation and running costs
• Flexible production: Switch between profiles to match daily orders
