Steel strands come in two main types: single-filament and stranded wire production. They play a crucial role in various fields such as bridge construction, building projects, water management, energy infrastructure, and geotechnical engineering. As the domestic construction sector continues to grow, we see more high-rise structures being built, all of which rely heavily on steel strands. This material is becoming increasingly integral to modern life. Generally speaking, the toughness of steel strands depends on the number of steel wires they contain. More wires mean greater strength—a basic principle that most people understand. However, when using steel strands, they typically need to be combined with concrete, anchors, or similar materials. While steel strands offer excellent tensile strength, they are inherently prone to corrosion. Exposure to environmental factors like wind, rain, and sunlight can significantly degrade their performance, reducing their lifespan. Hence, the protective coating on the surface of steel strands becomes vital for maintaining their durability. A high-quality steel strand must not only rely on the number and quality of its internal wires but also prioritize corrosion resistance. Today, the most commonly used types of steel strands include galvanized steel strands and prestressed steel strands. Both are made up of multiple wire strands, and their surfaces can be treated with additional layers such as zinc, zinc-aluminum alloys, aluminum cladding, copper plating, or epoxy resin coatings, depending on the application. These protective layers not only shield the strands from environmental damage but also enhance their overall strength. In summary, while steel strands are essential in construction, their effectiveness depends not only on their core components but also on the external protection they receive. Investing in better surface treatments can extend the lifespan and reliability of these critical structural elements, ensuring safer and more durable infrastructure.
