Shear Connectors (Type SD acc. To ISO 13918)
Shear connectors are typically used in composite steel construction to tie the concrete to steel members and resist shear forces between the concrete slab and steel members. They are widely used in steel building, bridges, etc. Welding through Metal Deck is available for this stud, for this option, special ceramic ferrule type UFT is recommended.

Not listed dimensions available upon request.
Material & Surface Treatment
Shear connectors are made of quality low carbon steel grade SWRCH15A, the mechanical properties meet the standard ISO 13918 and AWS D1. 1 type 8, please refer to chapter 2.1 clause “Material”. Surface treatment of phosphate planting is available upon request.
Flux
All shear connectors have a solid flux load – appropriate aluminum ball insert into the center of the studs tips.

Ceramic Ferrules for Shear Connectors Weld through Metal Deck (Type UFT)
Special Ceramic Ferrules for shear connectors welding through metal deck (mostly zink – plated deck sheets on the steel beams). As there are high amounts of degasification through zink evaporation when weld shear connectors through zink – plated deck sheets, the type of UFT ceramic ferrules with larger combustion chamber and larger vents can considerably improve the welding results.
