1. Definition of PBR Panels
PBR (Panel Bracket Rib) is a common corrugated roofing or wall panel standard characterized by **high rib depth** (typically 1.5 inches/38mm) and wide-spaced reinforcement ribs. It offers excellent wind resistance, drainage, and load-bearing capacity, widely used in industrial plants, warehouses, agricultural facilities, and more.
PBR roll forming machines are specialized equipment designed to continuously shape metal coils (e.g., galvanized steel, aluminum, prepainted sheets) into panels with this specific cross-sectional profile.
2. Core Features
High Efficiency: Utilizes multi-stage roller pressing to gradually form complex cross-sections, with speeds reaching 20-50 meters/minute.
Modular Tooling: Enables quick mold changes to accommodate materials of varying thicknesses (0.3-1.5mm) and types (steel, aluminum, stainless steel).
Smart Control: Equipped with PLC/CNC systems for automated feed speed adjustment, length cutting (e.g., fixed-length shearing), and fault diagnostics.
Energy Efficiency: Some models integrate servo motors to reduce power consumption and material waste (scrap rates typically below **3%**).
Precision: Tolerances controlled within **±1mm**, ensuring tight seams and compliance with U.S. standards like ASTM.
3. Applications
Construction: Producing PBR roofing/wall panels for commercial buildings, logistics centers, etc.
Transportation: Manufacturing vehicle body panels, container exteriors.
Home Decor: Customized metal ceilings, partitions, and decorative elements.
