GB10433 Shear Stud
GB10433 Welding Shear Stud
GB10433 Welding Shear Stud refer to the installation of steel pins or grommets, that extend out of the top flange of a steel support beam. Normally the GB10433 Welding Shear Stud are welded, with a spot welder, after the metal deck is installed over the supporting structural steel. The spot welder will burn through the metal deck and attach the GB10433 Welding Shear Stud directly to the top of the steel beam.

Product Details
Product Introduction
Headed shear studs manufactured to GB/T 10433, the Chinese national standard for arc stud welding fasteners used in steel-concrete composite construction. The stud is welded directly to the top flange of a steel beam through the profiled metal deck, forming a reliable shear connection between the structural steel and the poured concrete slab. This connection transfers longitudinal shear forces and enables composite beam action under service loads.
Material & Mechanical Properties
Fabricated from weldable low-carbon steel in accordance with GB/T 10433 chemistry requirements. After drawn-arc stud welding, the fusion zone achieves full penetration into the beam flange and meets the specified tensile and bend test criteria. The welded stud develops shear capacity exceeding the shank cross-sectional strength, ensuring the connection fails in a ductile mode rather than at the weld interface.
Dimensions & Identification
-
Nominal diameters: 10 mm to 25 mm
-
Length before welding: 40 mm to 300 mm
-
Head form: cylindrical cheese head with a flat top surface
-
Marking: each stud head is embossed with the manufacturer’s identification mark per GB/T 10433 traceability requirements
Ceramic Ferrules
Each stud is supplied with a cordierite ceramic ferrule. The ferrule shields the weld pool from atmospheric contamination during the arc cycle, shapes the fillet weld, and withstands the rapid temperature rise and thermal shock of stud welding without melting or fracture. Ferrules are removed after the weld solidifies.
Installation & Weld Integrity Verification
Installation is performed using drawn-arc stud welding equipment after the profiled steel deck is placed over the supporting beam. The stud gun lifts the fastener, initiates an electric arc that melts the stud tip and a localized area of the beam flange, then plunges the stud into the molten pool—penetrating the deck without the need for pre-drilled holes.
Post-weld integrity is verified by visual examination of the full 360° flash and fillet weld dimensions. A mechanical bend test follows: striking the side of the welded stud with an iron mallet bends the stud to the angle specified in GB/T 10433. A correctly welded stud remains attached and deforms without fracture at the weld joint. Studs that break at the interface under this shear-bending force are deemed defective and must be replaced.
Application Suitability
Composite floor decks in high-rise buildings, bridge decks, industrial platforms, and steel-framed structures where the concrete slab is designed to act compositely with the supporting steelwork. GB/T 10433 welding shear studs are the standard shear connector specified in Chinese construction codes for composite beam design.
