Highway steel guardrail H post
The galvanizing process of FORST guardrail beam H post can usually be carried out using the following steps:
1. Pretreatment: Clean the post surface to remove any dirt, oxides or grease. This can be achieved by methods such as solvent cleaning, sandblasting or pickling.
2. Pickling: Soak the post in an acidic solution, such as hydrochloric acid, to remove any further oxides or scale. Pickling can provide a better bonding surface.
3. Cleaning: Rinse the post with clean water to remove pickling residues.
4. Ventilated and dry: Place the post in a ventilated area to allow it to dry thoroughly.
5. Galvanizing: Soak the dry post in a molten solution containing zinc, usually a hot-dip galvanizing process. This creates a zinc coating on the surface of the post to provide protection against corrosion and rust.
6. Cooling and solidification: After taking out the galvanized post from the molten liquid, it is cooled and solidified to ensure that the coating is firmly attached to the surface of the post.
