| Raw Material & Structural Mechanical Grade | Premium structural carbon steel raw stock, with minimum tensile strength reaching ≥450N/mm², fully compliant with ISO 13918 mechanical performance benchmarks. Every batch of steel bars undergoes chemical composition and tensile testing prior to hot forging to guarantee stable load-bearing capacity for large infrastructure projects. |
| Product Core Structure & Positioning | NA type cylindrical round head solid arc welding shear stud, positioned as a structural fastening screw for steel-concrete composite systems. It matches a disposable ceramic ferrule for precise arc welding positioning, serving as a critical shear connector between steel beams and concrete floor slabs. |
| Welding End & Fastening Working Principle | The solid unthreaded shank features a tiny ignition tip at the tail, designed to work with dedicated arc stud welding equipment. High-temperature arc fusion bonds the stud firmly to the steel base plate; the cylindrical head evenly transfers shear and tension stress between steel and concrete layers. |
| Cylindrical Round Head Load-Bearing Design | Symmetrical thick cylindrical round head eliminates localized stress concentration points. This uniform profile delivers consistent force distribution under floor live loads, concrete shrinkage stress and bridge dynamic loads, preventing cracking or detachment at the welding joint. |
| Multi-Country International Standard Compliance Framework | Manufactured to meet six core global fastener specifications: DIN, GB, ANSI, BSW, JIS, GOST, with ISO 13918 as the primary industry standard. Unified dimensional tolerances enable seamless interchangeability for cross-border building, bridge and industrial construction projects. |
| Surface Finish & Custom Anti-Corrosion Solution | Standard delivery adopts natural raw black steel finish, ideal for conventional indoor and inland welding construction. Hot-dip galvanized surface treatment is available as a customized upgrade, greatly improving salt-spray resistance for coastal, high-humidity and chemically corrosive site environments. |
| Dual-Layer Export Protective Packaging System | Inner waterproof polybags isolate individual studs from dust and minor surface scratches; outer reinforced heavy-duty export cartons resist stacking compression and impact damage during ocean and overland long-distance transit. Large bulk orders support pallet stacking to optimize container loading efficiency. |
| Dimensional Range & Customization Flexibility | Standard production size spectrum spans M10 to M25 with multiple fixed length options. Customizable parameters include total shank length, cylindrical head thickness and welding tip size, all produced strictly according to customer signed technical drawings or physical sample validation. |
| Brand, Origin & Continuous Production Capacity | HYS is our officially registered trademark; all hot forging, precision cutting, dimensional sorting and quality inspection processes are fully completed domestically in China. Stable mass production capacity supports small sample trial orders and large-volume bridge/floor engineering bulk contracts simultaneously. |
| Full End-to-End QC Manufacturing Workflow | Complete standardized production sequence: carbon steel bar cutting → high-temperature hot forging cylindrical head forming → tail ignition tip precision trimming → dimensional tolerance sorting → mechanical strength batch sampling test → sealed carton packaging. Random inspection follows strict ISO 13918 quality control protocols. |
| Comprehensive OEM & ODM Bespoke Service Package | Full flexible customization modes: adjustable stud geometry dimensions, optional galvanized anti-rust coating, custom branded packaging printing and neutral unlabeled export cartons for distributor private-label cooperation programs. |
| Pre-Production Drawing Validation Protocol | All non-standard customized welding stud orders require signed technical drawing confirmation from buyers before mass production launches. This process thoroughly eliminates risks of dimensional mismatch, insufficient welding fusion and hidden structural load failures on construction sites. |
| Primary Engineering Application Scenarios | Specially engineered for steel-concrete composite floor slabs, metal steel deck systems, highway and municipal bridge main beams, heavy industrial workshop steel frames, high-rise building load-bearing beam structures and large-scale infrastructure shear connection projects. |
| Full-Cycle Customer Technical & Logistics Support | Free physical test samples are provided upfront for pre-verification of welding compatibility, tensile-shear strength and fusion quality. Production lead times are flexibly adjusted between 7-30 working days based on total order quantity and customized requirements. |
| Unthreaded Solid Shank Technical Specification | Thread-free solid cylindrical shank is optimized for full penetration arc welding. Uniform shank diameter ensures steady melting and complete bonding with the steel base plate, avoiding thread gap defects that would reduce overall shear bearing performance. |
| Strict Precision Dimensional Tolerance Control | All critical measurable parameters (shank diameter, cylindrical head height, total stud length, ignition tip size) adhere rigidly to ISO 13918 structural fastener precision tolerance grades, ensuring uniform batch-to-batch sizing for automatic welding machine feeding stability. |
| Shank Knurling Configuration Status | Standard finished shear studs utilize smooth non-knurled solid shanks by default. Knurled textures are not applicable to this arc welding product type, so knurl specification is marked N/a with no optional knurl upgrade available. |
| Core Product Competitive Advantages | ISO 13918 certified NA cylindrical head arc welding shear stud screw, high ≥450N/mm² structural tensile strength, dual natural/galvanized surface options, stable hot-forged forming quality, automated large-volume mass production, free pre-order validation samples and full drawing-backed OEM tailored service for global building infrastructure steel-concrete connection hardware supply chains. |
