Our headed anchor studs, shear connectors, and weld studs are manufactured in compliance with EN ISO 13918 and AWS D1.1 / D1.5 standards.
Designed for high-strength anchorage and shear transfer in structural concrete and steel composite applications, these products ensure exceptional performance, durability, and installation efficiency.
Our weld studs and headed shear connectors are commonly welded onto embed plates, beam flanges, or steel decking using arc stud welding processes. They provide a permanent mechanical bond between steel and concrete, making them ideal for large-scale infrastructure and industrial projects.
All items are produced from low carbon steel, stainless steel (SS304, SS316), or alloy steel, and available with plain, zinc-plated, or hot-dip galvanized finish to meet different environmental and corrosion resistance requirements.
