Galvanized Bolt Manufacturer In China
Ningbo Teng Qi Fasteners Co., Ltd is a leading galvanized bolt manufacturer in China. A galvanized bolt is a type of steel bolt that has undergone a galvanization process. Galvanization is a method of applying a protective zinc coating to the surface of steel or iron to prevent corrosion. This coating creates a barrier between the steel and the surrounding environment, making galvanized bolts highly resistant to rust and corrosion, even in challenging outdoor or marine conditions.
The galvanization process typically involves dipping the steel bolt into a bath of molten zinc. This results in a layer of zinc coating the entire surface of the bolt, including its threads and shank. Galvanized bolts are easily recognizable by their silver-gray appearance, which distinguishes them from untreated black steel bolts.
Galvanized bolts are commonly used in outdoor and marine applications, construction, and anywhere the bolts will be exposed to moisture or corrosive elements. They provide long-lasting protection against rust and can extend the lifespan of the fasteners and the structures or equipment they are used to assemble.
