Besi Hollow
STRUCTURE & PHYSICSintermediate
Definition
Hollow steel tube — a structural steel member with a rectangular, square, or circular hollow cross-section, used for columns, beams, trusses, and secondary frames in modern Indonesian buildings. Besi hollow is lighter than solid steel I-beams of equivalent strength, easier to work with in design and fabrication, and has become the standard choice for commercial and institutional construction.
Example
A Jakarta office building's primary structure typically uses besi hollow columns in the main grid (200×200×8 mm, for example) — the hollow section providing torsional rigidity and a clean architectural profile when exposed or minimally finished.
