Zinc coating is a bolt process that is widely used now. It can not only improve the service life of hex bolts, but also make the hex bolts more beautiful. Jinrui can provide you with two kinds of galvanizing commonly used for hexagon bolts, One is electro-galvanized. After electro-galvanizing, if the hexagonal bolt encounters humid air, the zinc film on the surface of the bolt can isolate the air from the bolt base, so that the bolt wil not be easily corroded.

Hexagon bolts are a type of fastener consisting of a head and a threaded rod (a cylinder with an external thread), which need to be matched with a nut to fasten and connect two parts with through holes.

Carbon steel seamless steel pipe is a kind of long steel with it. Steel pipes have a hollow section and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials.

Carbon structural steel coil/strip refers to carbon steel containing less than 0.8% carbon, which contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties.
