the choice between steel and concrete is not merely a technical one but a strategic decision that impacts project timeline, lifecycle cost, environmental footprint, and future adaptability. While concrete remains a viable option for certain applications, steel structure, as championed by Dunbon, presents a compelling case for modern construction. Its advantages in prefabrication efficiency, structural performance, sustainability, and long-term adaptability make it the superior "skeleton" for the vast majority of industrial, commercial, and large-span projects today. It is the material that best aligns with the demands for speed, quality, and resilience in the 21st century.
