Shear Connectors
Overview
Shear Connectors are essential structural components used to transfer shear forces between concrete slabs and steel beams, ensuring composite action in multi-story buildings, industrial sheds, and PEB structures. They play a critical role in enhancing the strength, stability, and load-carrying capacity of steel-concrete composite floors.
At BSSM Infra, we supply high-quality shear connectors that meet international standards, offering durability, high tensile strength, and precise performance for a wide range of construction projects.
What are Shear Connectors?
Shear connectors, commonly known as stud connectors or headed studs, are welded onto steel beams and embedded in concrete slabs. They create a mechanical interlock between steel and concrete, enabling the two materials to act as a single composite unit.
This composite action increases the overall structural stiffness, load-bearing capacity, and resistance to bending and shear forces, making shear connectors a vital component in modern steel-concrete construction.

Shear connectors are steel components welded to steel beams to create a strong bond between the steel section and the concrete slab. They help in transferring shear forces and ensuring composite action between steel and concrete.
They improve the load-bearing capacity, stiffness, and overall stability of composite structures, reducing deflection and enhancing durability.
They are widely used in composite beams, bridges, floor decks, and other steel–concrete composite structures.
Shear connectors are typically made from high-strength steel that meets the required welding and structural standards.
They are generally welded onto steel beams using automatic or semi-automatic stud welding machines before concrete is poured.
Yes. Depending on the project design, size, and load requirements, shear connectors can be manufactured in various diameters, lengths, and shapes.
Common types include headed stud connectors, channel connectors, and perfobond rib connectors, each suited for specific applications.
Once embedded in concrete, they require minimal to no maintenance as they are protected from corrosion and external wear.
They ensure composite action between steel and concrete, allowing both materials to share loads efficiently and reducing overall material usage.
Yes. They undergo rigorous mechanical and weld testing to ensure compliance with relevant standards and reliable performance on-site.
