A similar opportunity is emerging in high-rise construction, where developers are increasingly adopting steel to accelerate project timelines without compromising structural strength, safety, or scalability. These projects require a hybrid construction approach that combines Pre-Engineered Building systems with Heavy Structural Steel. This combination brings together speed of execution, high load-bearing capacity, design flexibility, and the ability to support future expansion. Our dual capability in PEB and Heavy Structural Steel enables the Company to provide comprehensive, end-to-end steel construction solutions. It further strengthens our positioning across data centers, high-rise buildings, and other complex heavy-structural applications.
