PURPOSE: A weld-free roll-forming steel curtain wall system is provided to lower equipment costs while maintaining basic performance such as the structural performance of a curtain wall frame. CONSTITUTION: A weld-free roll-forming steel curtain wall system (100) comprises a nut bonding part, a fixing nut (150), a bolt (160), an adapter (180), and an inside filler (170). The nut bonding part is formed inside a frame which is fixed by coming in touch with a glass to fix the fixing nut. The adapter is installed in between the head part of the bolt and the opposite tip end of a fixing nut head part. The adapter moves towards a cross section of the frame when the bolt rotates and moves towards the nut head part. The inside filler is arranged between a cross section of the frame and the adapter.
