What material is the main warehouse in Quadrant 2 constructed from?

The main warehouse in Quadrant 2 is constructed from steel, which is a robust and durable material commonly used in modern construction. Steel's strength allows it to support large structures and heavy loads, making it ideal for warehouses that frequently store substantial quantities of goods. Additionally, steel provides resilience against various environmental factors, such as wind and fire, enhancing the building's safety and longevity.

While wood, brick, and glass have their respective uses in construction, they do not offer the same level of structural integrity and protection that steel does for a warehouse setting. Wood is susceptible to decay and fire, brick can be heavy and less adaptable, and glass, while aesthetically pleasing, lacks the necessary strength for warehouse construction. Thus, steel is the optimal choice for creating a secure and efficient warehouse in this context.
