High-strength hot-dip galvanized threaded rod. Manufactured using the hot-dip galvanizing process, with uniform zinc layer thickness and extremely strong adhesion. Excellent anti-corrosion and rust resistance, capable of withstanding harsh outdoor environments such as rain, snow, humidity, and saline-alkali conditions. Specifically designed for construction engineering, outdoor facilities, communication towers, and other long-term exposed applications. Service life far exceeds that of other conventional coated threaded rods.
