Send Message Request a Quote

The stud is also known as shear stud, weld stud, or shear connector. It is suitable for the penetration welding between steel beam and steel deck. The basic specifications are ¢ 13, ¢ 16, ¢ 19, ¢ 22, and ¢ 25. Special specifications are also available.

The common accessory for the stud is the ceramic ring. The specification of the ring should match with that of the stud.

		No crack in the welding seam.
	Bending Test	Fix the stud on test tool. Alternatively bend the stud in positive and negative 30° directions until it breaks. Or, just bend it in 90°. No crack in the welding seam.
