AWS D1.1 Headed Welded Shear Stud Rail | Shearfix Punching Shear Reinforcement Stud Rail

Headed Welded Shear Stud Rail is a high-performance prefabricated concrete punching shear reinforcement system for flat slab-column structural connections. Manufactured by Tarco Industry China, our Shearfix shear stud rail fully complies with AWS D1.1 welding standard. It provides reliable punching shear resistance to prevent slab failure, replaces traditional stirrups, and improves on-site concrete reinforcement efficiency for commercial and civil construction projects.

What is Headed Welded Shear Stud Rail for Punching Shear Reinforcement

The shear stud rail assembly consists of double-headed forged steel shear studs factory-welded to flat steel rail plates. As a critical structural punching shear reinforcement solution, it distributes concentrated column point loads over a larger concrete surface, solving punching shear risks in thin flat slabs. Compared with conventional on-site stirrup reinforcement, Shearfix shear stud rail delivers higher shear capacity, stable structural performance and faster installation speed.
