At Kirby Southeast Asia, we specialize in designing and supplying steel pre-engineered buildings and structures, employing cutting-edge solutions like castellated beams. A castellated beam contains a regular and recurring pattern of hexagonal holes. The pattern is cut lengthwise across two halves, offset, and then welded together to form a single extended beam. This innovative design enhances the beam’s strength-to-weight ratio and offers a myriad of advantages: ✔ Supports long span. ✔ Less deflection. ✔ MEP ducts and pipes can be installed through the web
