DSQ Frame System

DSQ Frame System is Daiwa's original Rahmen structure, which applies thickened square steel pipes for columns and H-shaped steel for beams. By employing Hight Frequency Induction Heating Thickening Method, the latest steel process technique, thickness of colum and beam joint is increased double and performs strength and tenacity. There are two methods of connecting beams, which are One-sided bolts type and Welding connection type. Special high stregnth bolt, which the bolt can be easily tightened from out side of steel pipe when connecting a beam to a colum, is used for One-sided bolts type. The new technology of world standard protects properties and life of people who live there.
