22×125 Stud Welded Shear Connector: High Load Capacity for Deep Concrete Applications
The 22×125 stud welded shear connector is a heavy-duty fastening element designed to provide maximum connection strength in thick concrete slabs and heavily loaded structural systems. It delivers safe, durable, and long-lasting performance in seismic and industrial applications.
Diameter: 22 mm
Length: 125 mm
Material: Low-carbon, cold-drawn, high-strength steel
Application: Automatic stud welding system
Ceramic Compatibility: Suitable for use with ceramic ferrules
Standards: EN ISO 13918 and ISO 14555
Advantages
High tensile and shear strength: The 125 mm length provides maximum anchorage within concrete.
Ideal for thick concrete sections and heavy-load areas: The combination of diameter and length ensures strong bonding and reliable load transfer.
Resistant to seismic and heavy-load conditions: Enhances structural rigidity and overall safety.
Fast and efficient installation: Easily applied using automatic stud welding systems.
Long service life: Resistant to impact, vibration, and thermal stresses.
Applications
- Bridge and viaduct decks
- Thick concrete floor slabs
- Industrial machinery foundations
- Seismic strengthening systems
- Prefabricated structural elements
- High-rise steel frame structures
Application Information
The 22×125 stud welded shear connector is positioned perpendicular to the steel surface and welded using an automatic stud welding gun together with a ceramic ferrule. After the high-current welding process is completed, the weld area is cleaned and prepared for concrete placement. Its extended length enables deep embedment within the concrete, improving structural integrity and connection performance.
