Product Introduction
What Are Shear Studs, and Why Do Composite Structures Depend on Them?
Shear studs — also called shear connectors — are headed steel fasteners arc-welded onto structural steel beams before the concrete slab is poured. Once embedded, they lock the steel frame and the concrete deck into a single composite section.
- Mechanical interlock: the welded shank and forged head resist the horizontal shear force that develops between steel and concrete under load, so the two materials act as one beam instead of sliding against each other.
- Built for arc stud welding: every shear stud we produce is sized and flux-tipped for drawn-arc welding, so it fuses to the flange in under a second with a consistent, full-strength weld collar.
- The result on site: engineers get a composite deck that carries more load with less steel tonnage, fewer field bolts, and a faster erection schedule — which is why shear connectors are specified on nearly every steel-frame building and bridge deck today.

Quick Answer
Frequently Asked Questions About Shear Studs
Shear studs are critical structural components used to create strong mechanical connections between steel beams and concrete slabs. Below are common questions about shear studs, including their applications, welding process, specifications, compatibility, and selection considerations. This guide helps engineers, contractors, and distributors better understand shear connector studs for steel structure construction and composite building projects.
Shear studs, also known as shear connector studs or headed studs, are used to connect steel structures with concrete slabs by transferring shear forces between the two materials. They are widely applied in composite floors, steel bridges, industrial buildings, and infrastructure projects to improve structural strength and stability.
Shear studs are specially designed for structural load transfer between steel and concrete, while general weld studs are mainly used for fastening and attachment purposes. Shear studs usually feature a welded head that provides better anchorage inside concrete, making them ideal for composite construction applications.
Shear studs are commonly installed using the drawn arc stud welding process, where a stud welding machine creates an arc between the stud and the base metal before pressing the stud into the molten weld pool. This process forms a strong metallurgical bond between the shear stud and the steel surface.
Shear studs are available in various diameters and lengths to meet different structural requirements. Common shear connector stud sizes include diameters from 10 mm to 25 mm, with customized dimensions available according to project specifications, welding standards, and load requirements.
Drawn arc stud welding machines are the most commonly used equipment for shear stud welding because they provide stable welding current and sufficient power for large-diameter studs. The suitable machine model depends on shear stud diameter, welding capacity, project scale, and required welding standards.
A reliable shear stud supplier should provide consistent product quality, accurate dimensions, suitable material grades, and compliance with international standards such as ISO 13918. Buyers should also consider the supplier’s manufacturing capability, quality control system, technical support, and experience in serving global construction projects.
