The galvanized layer thickness is about 5-10µm. It will be destroied during the production process, such as cuting, welding and polishing. The steel going rust very soon!
Our technology is doing Hot-dip galvanized after produce, and then Electrostatic spray. It make sure the galvanized layer thickness keep about 80µm.
It's the best rust-proof technology. Do not only focus on price, please pay attention to the quality more!
