High-strength yellow zinc plated threaded rod. Yellow zinc plating is applied to the surface of the high-strength substrate, forming a multi-colored passivation film that enhances anti-corrosion and rust resistance. The coating is wear-resistant and not prone to peeling. Combines practicality with aesthetics. Suitable for outdoor mildly corrosive environments, building brackets, hardware fittings, and similar applications. Service life far exceeds that of ordinary coated products.
