Origin China
Shear connector (it is also named shear stud) 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. Plenty of steel construction(such as steel building, steel beam, steel bridges, etc.) uses shear connector widely. Butler shear connectors meet the following standards:
• ISO 13918: 2008: 2008 Welding – Studs for arc stud welding, type SD1
• GB/T 10433: 2002 Cheese Head Studs for Arc Stud Welding
• JIS B 1198-1995 Headed Studs
• AWS D1.5: 2002 Bridge Welding Code, type B
• AS/NZS 1552.2: 2003 Australian/New Zealand Standard – Structural Stud Welding
• BS 5400: 2005 Steel, Concrete, and Composite Bridges
• AWS D1.1: 2015 Structural Welding Code-Steel, type B
There’re 5 production lines for shear connector studs in our workshop.
Cold Forging Machines
Raw materials are carefully selected to achieve the necessary mechanical conditions
Using new cleaning oil machine to clean oil after the shear stud by cold forging
Mechanical Test
Shear studs are also mechanically tested. Bending tests are performed for each order after welding. Shear studs are also tested for elongation and tensile strength using our own testing equipment. Shear Stud Connector
Welding Test
Shear stud are regularly weld tested .
The test implies that the stud is bent to an angle of at least 60° or until breakage occurs.
Quality raw material
We choose the quality mild carbon steel from BIG Steel Factory.
Taking M19*100mm for example
Head thickness(mm)
Body diameter(mm)
Forehead diameter(mm)
Being able to determine the chemical composition of the raw materials for shear studs is a must for a good quality end product.
Tensile and yield strength tests are carried out regularly for each order and test certificates are supplied on request. ASTM A108 Shear Studs
