EN ISO 13918 Arc Studs

EN ISO 13918 Arc Studs

his series of studs (shear connectors) complies with international standard EN ISO 13918:2018, fully conforming to European and global manufacturing specifications for welded studs and superseding the older EN ISO 13918:2008. They serve as core connection components dedicated to arc stud welding. The product includes stud bodies and matching ceramic ferrules. Manufactured in strict accordance with full-standard requirements covering dimensional tolerances, material composition, mechanical properties, welding procedures and inspection acceptance criteria, they are mainly used for shear connections in steel-concrete composite structures. The studs effectively transfer interface shear force and restrain component slippage to improve the overall load-bearing stability of buildings. They are standardized fasteners specially used for international projects, steel structure bridges and high-end prefabricated buildings.

III. Core Product Advantages

1. International standard compliance with great global compatibility Manufactured strictly in accordance with the latest EN ISO 13918:2018 international standard. Dimensions, materials, mechanical properties and welding parameters fully meet global steel structure codes, satisfying acceptance requirements for overseas projects in EU, Southeast Asia, the Middle East and other regions. Compatible with both imported and domestic stud welding machines for maximum versatility.

2. Premium material and stable welding performance Forged from dedicated high-quality carbon steel with high material purity and good thermal stability. No brittle fracture or cold joints during welding. Paired with dedicated ceramic ferrules, it stabilizes the electric arc, isolates air and prevents welding spatter. The finished weld fillet is full and uniform with dense and solid welds, eliminating risks of component detachment and slippage.

3. Strong shear resistance and high structural safety As core shear connectors for steel-concrete composite structures, they efficiently transfer interfacial shear force between steel beams and concrete slabs / bridge decks, restricting relative displacement and greatly improving overall stiffness and bearing capacity of buildings and bridges. Vibration-resistant and tolerant of temperature fluctuations, suitable for complex working conditions from -40℃ to 120℃, maintaining reliable performance over long service life.

4. Efficient construction, adaptable to automated operation Compatible with fully automatic arc stud welding. No complicated pre-treatment required. Single-shot welding forms the joint, delivering simple procedures and fast construction speed to shorten steel structure installation cycles. Ideal for mass standardized engineering and reduces labor and construction costs.

5. Strict quality control with traceability and inspection support Full-process quality inspection including visual & dimensional check, hardness test, tensile and shear mechanical tests and non-destructive testing. Factory certificates and test reports can be supplied for every batch to meet stringent acceptance criteria of high-end and international projects.

IV. Application Scope

Overseas steel structure projects, export prefabricated buildings, overseas infrastructure projects Steel-concrete composite slabs and steel beam-concrete connection nodes in high-rise buildings Deck paving works for highway, railway steel bridges and sea-crossing bridges Long-span steel structures such as large industrial workshops, convention centers and stadiums Municipal steel trestles, photovoltaic steel bases and heavy-load steel-concrete supports All steel-concrete composite structure projects requiring standardized shear connections
