Shear Connector’s raw material

• Sino Stone choose the famous Xingtai Steel factory to purchase the optimalraw materials with good mechanical properties and weld performance,which can ensure the shear connectors’ mechanical properties to matchclient’s requirement.in different steel constructions.

Size as per ISO13918:2008

a Excess diameter or production impressions in the shaft area below the head are permitted up to 0.5mm, provided they do not affect proper plunge.b Tolerance on l2 is +1/-2 mm.c For special conditions, e.g. through-deck stud welding, the dimensions and the tolerances are not applicable.d May be reduced to 29mm for shear application.e Use of the optional dimension depends on national regulations.



Dimension as per standard



• Sino Stone uses 3 die 3 blow cold forging machine to produce shearconnector with chamfer which depends on the mold of cold forging machine.

• It can’t produce the shear stud with chamfer when using one die two blowcold forging machine, which is popular with most factory in Handan City ofHebei Province.

Chamfer or not?

Note: You seldom find the shear connector with chamfer in the factory of Handan City in Hebei province, this is one season for their low price.



• There are two ways to clean oil after the shear

stud by cold forging. Sino Stone uses new

cleaning oil machine(left photo), most factories

in Handan use the rotating cylinder which is full

of shear stud and wooden piece together.

Cleaning Oil Process



• Most factories in China install aluminum ball by

hand. However, Sino Stone uses automatic

riveting machine to install it.

Installing aluminum ball process



• Thear are two types packaging for shear connector:

– Barrel&Pallet: About 200kgs/barrel, 6barrels/pallet

– Carton&Pallet: About 25kgs/carton, 36cartons/pallet

Package of Shear Connector



• UF ceramic ferrule is designed for unthreaded stud and

shear connector, there are two types of UF type, one is

for normal welding with 20 teeth, another is for through

deck(it is also called thru-deck) welding with 8 teeth.
