Guardrail barrier
FORST guardrail beam hot-dip galvanizing is a commonly used anti-corrosion process,
1. Preparatory work: Clean and surface-treat the guardrail to remove oil, rust and other impurities on the surface to ensure the adhesion of the coating.
2. Pickling: immerse the guardrail in an acidic solution such as hydrochloric acid or sulfuric acid for pickling. Pickling can remove oxides and rust on the surface and improve the adhesion of the coating.
3. Pretreatment: The pickled guardrail is subjected to wet coating pretreatment. Phosphating, pickling and phosphating are usually used to form a layer of pre-coating to enhance coating adhesion and anti-corrosion performance.
4. Hot-dip galvanizing: immerse the pretreated guardrail in molten zinc solution for hot-dip galvanizing. Hot-dip galvanizing is to firmly combine the zinc coating with the substrate to form a uniform zinc layer to provide good corrosion resistance.
5. Finishing: Finish the guardrail after hot-dip galvanizing, remove excess zinc liquid and clean impurities, so as to ensure the surface finish and appearance quality.
