Our arc threaded studs comply with EN ISO 13918 standard. Manufactured from premium raw materials, they deliver stable welding performance and high connection strength. Widely used for arc stud welding in machinery, steel structure and other fields, available in multiple sizes to meet diverse project requirements.
Shear studs manufactured per EN ISO 13918 are critical arc stud welding fasteners applied for steel‑concrete composite construction. These shear connectors create firm mechanical bonding between steel beams and concrete slabs, transferring interface shear force effectively and preventing relative slip between different structural layers. Produced under strict standardised production workflows, our shear studs feature uniform metallurgical structure, consistent welding end geometry and reliable ductility performance. Each batch undergoes material inspection and welding capability testing to guarantee stable on‑site installation results. Unlike ordinary threaded studs, shear studs are purpose‑built for composite building systems, resisting shear load and partial uplift force. The high‑quality base material optimises welding fusion effect, reducing welding defects during arc stud welding operations. These studs help enhance the overall rigidity and bearing capacity of composite structures, extending the service life of whole building projects.

EN ISO 13918 shear studs serve as core connectors for steel‑concrete composite structures. Primary scenarios include high‑rise building composite floors, steel bridge decks, viaduct structures, commercial complex steel frameworks, and parking‑garage composite beams. Besides civil building engineering, these shear connectors are also adopted in industrial plant steel frames, offshore auxiliary steel structures and large‑scale public venue construction. When concrete is poured over steel beams, shear studs lock concrete and steel components together, enabling combined stress bearing. They are widely chosen by structural engineering firms, steel‑structure fabricators and construction contractors across European and global markets, complying with local building code requirements.
We are a professional manufacturer specialised in arc stud welding fastener series including EN ISO 13918 shear studs. We keep full awareness of international standard requirements for stud welding products. Many manufacturers can only supply basic dimensions, while we control full production links from raw‑material incoming inspection, hot forging, machining to batch sampling test.
What you can obtain from us:
We cooperate with numerous steel‑structure exporters and engineering purchasers, familiar with documentation requirements for European market imports.
Q1: What standard applies to these shear studs? A: Our shear studs follow EN ISO 13918, which covers arc stud welding studs and matching ceramic ferrules for European construction projects.
Q2: Can you produce non‑standard length shear studs? A: Yes. If standard catalog lengths cannot fit your design drawing, we support custom‑made production according to your drawing. MOQ requirement applies for custom items.
Q3: Do shear studs need to work with ceramic ferrules? A: For on‑site arc stud welding construction, matching ceramic ferrules are required to guarantee welding quality. We can supply matching ferrules together.
Q4: What surface finish do your shear studs have? A: Normally shear studs for composite concrete structures adopt plain bare steel surface. Special surface treatment can be discussed for special working environment.
