PU Roof Sandwich Panels
PU Roof Sandwich Panels separate roof panel selection from the general PU parent category so buyers can review profile, joint, accessories and quotation data more clearly.
PU Roof Sandwich Panel Overview
PU roof sandwich panels for industrial and warehouse roofing. Four-wave roof profile with customizable thickness, steel facing, color and length.
Final performance depends on selected model, thickness and engineering review. LIAOHE confirms final thickness, steel facing, coating, length and accessories according to project drawings and order requirements.
