Trapezoidal Roof Sheet Machine

A trapezoidal roof sheet machine forms metal roofing panels with angled trapezoidal ribs that deliver superior water drainage and structural spanning capability. Profiles such as IBR, PBR, HR-36, Delta Rib, and TR4/TR5 are the most specified roofing sheets across Africa, South America, and Southeast Asia for factory buildings, warehouses, and agricultural structures. The trapezoidal geometry channels rainwater efficiently while providing greater load-bearing capacity than simpler wave profiles.

Core advantages:

• Trapezoidal rib design for high drainage and span performance

• Forming speed 15–25 m/min with Mitsubishi PLC control

• Custom effective widths: 686mm, 762mm, 890mm, and market-specific sizes

• Supports 0.3–0.8mm galvanized and prepainted steel coils

• Hardened Cr12 cutting tools with HRC58–60 for clean, burr-free edges

FAQ: What distinguishes IBR from corrugated roofing profiles? — IBR (Inverted Box Rib) features a trapezoidal cross-section offering better water runoff and longer unsupported spans; corrugated profiles use a round wave pattern suited for economical, shorter-span applications.
