CS-Frame columns are composed of four-corner square tubes and corrugated side plates welded together, with concrete cast inside. The construction is template-free, support-free, fire-resistant, and ductile. Compared to equally reinforced concrete columns, CS-Frame columns have a 40% higher compressive strength, a 150% higher shear capacity, and a 22% higher bending capacity. Adopting CS-Frame columns and the Jieyue 2.0 system eliminates the need for scaffolding and traditional formwork, saving about two months for a large frame structure project 10 meters high and 30,000 square meters in size.
