Thread Rod
Product introduct
Threaded rods, cylindrical components with helical threads, serve as essential mechanical elements for fastening and transmitting force across diverse industries, including construction, manufacturing, and automotive engineering. Their primary function is to securely join components or convert rotational motion into linear displacement through the interaction with nuts.
Carbon steel threaded rods, typically fabricated from materials like Q235 or 45 steel, are formed via rolling, cutting, or thread rolling processes. They offer a cost-effective solution with adequate strength for standard applications, such as assembling construction scaffolding or general machinery. However, their susceptibility to corrosion necessitates protective treatments like galvanization or blackening, especially in humid or corrosive environments, to prevent rust-induced loosening or structural degradation.
Stainless steel threaded rods, commonly made from grades 304 or 316, excel in environments where corrosion resistance is critical, such as marine applications, chemical processing, and medical equipment. These rods maintain integrity and performance over extended periods, eliminating the need for frequent maintenance. With excellent mechanical properties and resistance to oxidation, stainless steel rods ensure reliable, long-lasting connections, making them a preferred choice for high-stakes, demanding projects despite their higher initial cost.
