This article provides a comprehensive comparison between Aluminium Honeycomb Panels (AHPs) and Aluminium Composite Panels (ACPs), focusing on their structural differences, material composition, performance, and applications. Aluminium honeycomb panels are lightweight, rigid, and ideal for aerospace, transportation, and high-end architectural facades, while aluminium composite panels offer cost-effective versatility for cladding, signage, and interior design. The guide covers core materials, surface coatings, durability, and formability, helping architects and builders select the right panel based on project needs, budget, and environmental factors. Additionally, honeycomb composite panels, honeycomb sandwich panels, and honeycomb wall panels are explored for specialized applications. Whether prioritizing strength-to-weight ratio, longevity, or affordability, this guide ensures an informed decision for optimal construction performance
