Hot-Dip Galvanizing-The Manufacturing of Steel lattice tower

Hot-dip galvanizing is the most reliable and widely used anti-corrosion process for transmission towers, enabling maintenance-free service lives of over 40 years in harsh outdoor environments. Our hot-dip galvanizing process strictly follows standards such as GB/T 13912 and ASTM A123. The procedure begins with thorough surface preparation: components undergo acid pickling to remove mill scale and rust, followed by water rinsing, then immersion in a flux solution, and finally drying. Subsequently, the components are slowly immersed into a molten zinc bath at approximately 450°C, where iron and zinc undergo a metallurgical reaction to form a composite coating of iron-zinc alloy layers and a pure zinc top layer. After galvanizing, excess zinc is removed by vibration or centrifuging, followed by water-cooling and passivation, producing a uniform, bright silver surface.  Critical areas can be verified using coating thickness gauges and adhesion tests. Qingdao Best Tower monitors zinc bath composition and temperature in real time, ensuring a dense, corrosion-resistant, and aesthetically pleasing coating that provides ultra-long-lasting protection for the tower.
