Grid bolts, professionally known as high-strength steel grid structure bolts, are core specialized fasteners tailored exclusively for bolt ball joint grid systems. As the most critical load-bearing connection component of modern large-span steel structures,grid bolts directly determine the overall structural stability, long-term safety, and service durability of all grid building projects. Widely adopted in industrial warehouses, sports stadiums, exhibition centers, airport terminal canopies, and large coal storage grid structures, premium-grade grid bolts have become irreplaceable core accessories for steel grid engineering construction across global markets.
Unlike ordinary industrial structural bolts, high-performancegrid bolts are strictly manufactured in compliance with global and national industrial standards, including the authoritative GB/T16939-2016 standard. Featuring exclusive professional structural design and accurate mechanical performance parameters, grid bolts are not universal standard fasteners. They are professional customized structural connection parts that perfectly match supporting bolt balls, sleeves, cone heads, and sealing gaskets, enabling high-precision, fully assembled grid node connections without on-site welding operations.
Industrial-grade grid bolts feature a complete and standardized specification series, covering mainstream models from M12 to M64. Besides standard sizes, we support customized non-standard grid bolt products according to personalized engineering design requirements. According to structural types and application scenarios, grid bolts are mainly divided into ordinary high-strength grid bolts and enhanced anti-loosening grid bolts, perfectly meeting the construction demands of small and medium-span indoor grid structures and large-span outdoor heavy-load grid projects respectively.
Every batch of our grid bolts undergoes strict factory quality inspection, including ultrasonic flaw detection, tensile strength testing, and torque precision detection. All qualified grid bolt products are equipped with complete material test reports and official quality certificates, fully complying with international construction and safety standards to ensure zero quality risks for engineering projects.
