Hebei Longze is a premier global manufacturer specializing in high-performance Welding Studs and Ceramic Ferrules, engineered to provide critical anchoring solutions for large-scale steel construction and bridge engineering. Our Shear Connector Studs are precision-manufactured to meet rigorous DIN EN ISO 13918 and ASME B18.31.1 standards, ensuring maximum structural integrity and load-bearing capacity in composite floor systems and heavy-duty infrastructure projects.
By integrating precision-engineered aluminum flux tips for rapid arc ignition and high-grade Ceramic Ferrules to concentrate heat and shape the weld fillet, we deliver a clean, high-strength bond. Available in Low Carbon Steel and Stainless Steel, our solutions are optimized for high-speed installation and superior shear strength, making them the ideal choice for high-rise building composite decks, power plant structures, and railway projects.
