Shear studs are special welding fasteners for steel structures. With round‑head cylindrical design, they are welded to steel beams by arc welding to transfer shear force and prevent slip between steel and concrete. Made of high‑quality carbon steel, they feature good welding performance and complete sizes, widely used in factories, bridges and high‑rise building floor decks with stable supply.
IKING BS EN ISO 13918 shear studs are metallic arc welding fasteners engineered for steel‑concrete composite construction. Manufactured strictly following BS EN ISO 13918 international standards, these round‑head studs act as mechanical connectors to form reliable composite action between steel beams and cast‑in‑place concrete. Unlike ordinary bolts, shear studs are permanently fused onto steel substrates via stud‑arc welding equipment during on‑site or prefabrication workshop processes.
This standard‑compliant fastener eliminates relative displacement at the interface of steel and concrete layers. Under static load, dynamic load and seismic working conditions, it efficiently distributes horizontal shear stress across joint sections, avoiding delamination and slippage of composite components. Our ISO13918 shear studs go through multi‑step hot forging, surface finishing and batch quality inspection. Raw material carbon steel delivers balanced ductility and tensile strength, ensuring consistent welding usability without brittle fracture risks under long‑term building service cycles.

BS EN ISO 13918 shear studs serve as core connection hardware across composite steel‑concrete building sectors.
1.Composite floor system with metal deck profile steel: Installed on steel girder top flange for composite floor slab in multi‑story and high‑rise commercial buildings. It bears shear force when floors suffer live load and dead load
2.Bridge engineering: Widely applied for steel‑concrete composite bridge decks, box‑girder bridges, viaduct overpass projects, coping with vehicle cyclic dynamic loads.
3.Industrial plant construction: Heavy‑load factory workshops, logistics warehouse steel frame structures, large span steel‑concrete composite beam systems.
4.Prefabricated steel construction: Steel structure prefabrication workshop component processing, modular building composite joint connection.
5.Other infrastructure: Railway platform structures, parking garage steel‑concrete composite components.
As a professional manufacturer of BS EN ISO 13918 shear studs, IKING delivers far more than standard fastener products.
First, strict standard alignment. Every production batch is manufactured complying with BS EN ISO13918 requirements. We conduct raw material incoming inspection, forging process monitoring and finished‑product sampling test. Project‑required test documents can be supplied for your tender and construction acceptance work.
Second, flexible custom capability. When standard stock sizes cannot satisfy your drawing requirements, our production team supports non‑standard length adjustment. We can match special dimensions for overseas infrastructure and steel‑fabrication clients.
Third, stable large‑volume supply capacity. Our factory holds sufficient raw material inventory. Whether small sample trial order or full‑container bulk project orders, we can control production lead time reasonably, avoid project delay risks.
Fourth, one‑stop export‑oriented service. You will get professional pre‑sales technical consultation: our team helps you confirm suitable stud diameter & length according to your design drawings. After‑sales support covers packing scheme optimization, shipping document arrangement. We understand overseas steel‑construction project needs, helping you cut communication cost.
What you obtain from IKING: qualified ISO 13918 shear studs, transparent technical data, dependable lead‑time control, export‑ready documents, responsive technical support for your construction project.
A1: BS EN ISO 13918 specifies dimension, material property, mechanical performance and test requirement for arc‑welding shear connectors used in steel‑concrete composite structures. It is a widely‑accepted international norm for construction shear studs for global building projects.
A2: Yes. Please send your technical drawing or dimension list. Our engineering team will evaluate manufacturability and offer formal quotation accordingly. Minimum order terms apply for custom items.
A3: Our ISO13918 shear studs adopt black oxide natural finish. Extra paint, zinc coating is not suggested. Coating layer will interfere arc‑welding quality and cause welding defects.
Q4: What documents can you provide for import clearance and project acceptance?
A4: We can offer commercial invoice, packing list, bill of lading, material batch test certificate, factory inspection report, which supports customs clearance and site construction acceptance.
