Ceramic Ring (for Stud Welding)

　

　　This product is a core fastener for steel-concrete composite structures, also known as shear studs. It is a special welding component used for connecting steel crane beams, floor slabs, and concrete in steel structures. The studs are fixed to the steel beam by welding, and then concrete is poured. The studs and concrete form a strong shear key, effectively transferring shear force, preventing separation of steel and concrete, and improving the overall structural performance of the composite structure. The product is manufactured strictly in accordance with ISO13918/GB10433 standards. The welding end is reasonably designed, the arc is stable, and the weld is aesthetically pleasing and highly durable. It is an essential component for heavy steel structure factories and high-rise building steel-concrete floor slabs, and a core product for traders serving high-end engineering projects.
　　Core Parameters: Material: Carbon steel ML15Al; Surface treatment: Hot-dip galvanizing; Specifications: M16 M19 M22 (regular stock); Executive standard: ISO13918/GB10433
Recommended Accessories: Matching ceramic rings (for stud welding) are recommended to protect the welding core during welding and improve welding quality.

　　This product is a high-strength shear bolt specifically designed for steel structure main frames, strictly manufactured in accordance with the national standard GB3632. It is a highly efficient fastener that replaces large hexagonal bolts. Its core advantages are “precise installation and no need for re-inspection.” The bolt features a spline head at the tail, which is tightened using a special shear wrench. When the bolt’s pretension reaches the design value, the spline head automatically shears off, indicating successful installation. This eliminates the need for torque testing, significantly saving construction time and labor costs. The product is suitable for high-strength connections in steel structure main frames, providing even stress distribution, secure connection, and resistance to vibration and loosening. It is the preferred bolt for large-span factories, high-rise buildings, bridges, and other steel structure projects. It boasts stable quality, complete test reports, and compliance with relevant standards.

　　This product is a core fastener specifically designed for the main frame of steel structures. It features a 10.9S ultra-high strength grade and is manufactured strictly in accordance with national standards GB1228-1231. It is the core connecting bolt for main load-bearing components such as steel columns, steel beams, and steel trusses. The product is meticulously manufactured through multiple processes including cold heading, heat treatment, thread rolling, flaw detection, and anti-corrosion treatment. Each batch undergoes tensile strength, hardness, and torque coefficient testing, and defective products are strictly prohibited from leaving the factory. The bolt head and shank are firmly connected, and the threads are free of burrs and stripped threads. After installation, the load is evenly distributed, effectively resisting wind vibration, earthquakes, and vertical loads in high-rise buildings and large-span factories, making it a core guarantee for the safety of steel structure projects.

　　10.9 grade ultra-high strength level, tensile strength ≥1040MPa, yield strength ≥940MPa, suitable for core load-bearing splicing needs in steel structure main structures, beam-column connections, etc., with excellent load-bearing and pull-out resistance performance.

Made of selected 20MnTiB alloy steel, processed by tempering heat treatment, the entire stud has uniform hardness without discontinuities, and the threads are free of false threads and necking, eliminating the risk of fracture and stripping under stress.

Full-thread design with uniform pitch and high precision, ensuring tight engagement. The nut tightening position can be flexibly adjusted, suitable for various installation scenarios such as steel structure embedded fixing and steel beam-column connections, making construction convenient and efficient.

Dual anti-corrosion processes are available: electro-galvanizing is suitable for indoor steel structure embedding, while hot-dip galvanizing offers strong corrosion resistance and is suitable for humid and corrosive conditions such as outdoor, coastal, and bridge applications, ensuring a long service life.
Product Details: This product is a full-threaded stud specifically designed for core load-bearing applications in steel structure engineering. It features a 10.9 grade high-strength level and a continuous full-thread design, making it a core fastener for steel structure beam-column connections, embedded fixing, and steel component welding and splicing. The product is made from high-quality alloy steel through multiple precision processes including cold drawing, tempering heat treatment, precision thread rolling, non-destructive testing, and anti-corrosion coating. Each batch undergoes comprehensive testing of tensile strength, yield strength, hardness, and thread accuracy, and unqualified products are strictly prohibited from leaving the factory. The full-thread structure ensures uniform stress distribution without stress concentration points, effectively resisting vertical loads, wind vibration, and seismic forces in steel structure engineering. It is suitable for the embedding and splicing needs of various large-span factories, high-rise buildings, and bridge steel structures, providing a core guarantee for the safety and stability of steel structure engineering.
