Shear studs tie the concrete slab to the steel beam so the two act together as a composite section, and we stock headed shear connectors in Umm Al Quwain from 13 to 25 mm diameter and 50 to 300 mm long, with matching ceramic ferrules, for through-deck and direct welding with drawn-arc stud welding equipment.
A shear connector (shear stud, headed stud, Nelson stud) is a low-carbon steel stud with an enlarged head and an aluminium flux ball in its base. It is welded to the beam flange in under a second by a drawn-arc stud gun, the ceramic ferrule containing the weld pool. Once the concrete slab is cast around the studs, longitudinal shear is transferred from slab to beam, giving a composite beam up to twice as stiff as the bare steel. Studs are also used for anchoring plates to concrete and for composite columns and bridge decks.
Applications
- Composite floor decks in steel-framed buildings
- Bridge decks and composite girders
- Car parks, hospitals and high-rise floors
- Anchoring embedded plates and base plates
- Composite columns and shear walls
- Tank foundations and hardstanding slabs

This item is imported from approved mills and held in stock in our Umm Al Quwain warehouse alongside the anchor bolts, studs and plate washers we manufacture ourselves, so complete bolt sets ship from one source. Tensile, hardness and chemical testing is carried out by independent UAE-accredited laboratories, and EN 10204 3.1 certificates are issued with every batch. We supply across the GCC, MENA and Africa.
