B420C or B500B Double Head Deformed Rebar Punching Shear Reinforcement Studs Rail EC2 Standard
Slab‑column connections made stronger and thinner. Hot‑forged from BS4449 B500B high‑strength steel, these double‑headed studs provide
3× the anchorage area of conventional rebar, reducing slab thickness by up to 20% while meeting seismic detailing requirements.
Tarco B500B double head deformed rebar punching shear reinforcement studs, also named double headed punching shear studs or double end headed anchor rebars, are critical structural reinforcement components to eliminate punching shear failure risk at slab-column joints. Two upset forged heads at both ends enable reliable mechanical anchorage inside concrete, distributing concentrated column load evenly across the slab section.
All raw material adopts European standard B500B ribbed deformed rebar, consistent chemical composition and mechanical properties meet EN 10080, Eurocode 2 design requirements, perfectly matching technical specification for punching shear reinforcement across Poland, Germany, France, Czech and whole EU construction markets.
