Stud Rail / Punching Shear Resistor (PSR) Weld Stud
Stud Rail / Punching Shear Resistor (PSR) Weld Stud Specifically designed to be welded to flat rails. for slab connections to columns and foundations to provide a strong. ductile reinforcement system to prevent punching shear when columns punch through cast-in-place concrete. floors and foundation slabs. and to transfer concentrated loads further into the slab to create a larger shear area around the column.
