Applicable Scenarios: Heavy-duty factory columns: In heavy machinery plants and metallurgical workshops with large crane loads (lifting capacity ≥ 100 tons) and spans ≥ 30 meters, cross-shaped columns can serve as frame columns. Their bidirectional load-bearing capacity adapts to the combined effects of horizontal braking force and vertical loads from cranes, while their torsional resistance reduces structural vibration. Support columns for large stadiums: Grandstand columns or roof beam support columns for gymnasiums and convention centers. Cross-shaped columns can meet both vertical load-bearing and horizontal lateral displacement requirements, and their cross-sectional shape facilitates connection with beams, trusses, and other components. In high-rise buildings with more than 30 stories, cross-shaped columns can serve as the main vertical load-bearing components of the outer frame. Their bidirectional cross-section can simultaneously resist horizontal forces in two directions (wind loads and seismic forces), reducing component cross-sectional dimensions and saving building space (lighter and thinner than square columns). When the functions of upper and lower floors change (e.g., commercial space at the bottom, residential space at the top), and loads need to be transferred through a transfer floor, cross-shaped columns can serve as support columns for the transfer floor, utilizing their high stiffness to adapt to sudden load changes.
