Three wave galvanized crash guardrailis made of Q235 steel and adopts the process of cutting, punching, pressing plate and galvanizing. The three wave guardrail plate is generally 14 holes and 16 holes, with anti-collision grades of a and s. Installed on expressways, China's economy is developing at a high speed. 120 miles can no longer meet the needs of China's development. Speed increase is the only way, so the demand for three wave guardrails in China is increasing.
Highway guardrail hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: it is an effective metal anticorrosion way, mainly used in metal structure facilities in various industries. Three wave galvanized crash guardrailIt is to immerse the steel parts after rust removal into zinc solution melted at about 500℃, so that the surface of the steel members is attached with zinc layer, so as to play the purpose of anticorrosion.Three wave galvanized crash guardrail process: finished product pickling - washing - adding plating solution - drying - hanging plating - cooling - medicine - cleaning - polishing - hot dip galvanizing completed.
Cold galvanized coating is mainly anticorrosive through electrochemical principle, so it is necessary to ensure that zinc powder and steel fully contact, electrode potential difference, so the steel surface treatment is very important. Theoretically, electrogalvanizing can reach or even exceed the thickness of zinc layer of hot galvanizing, but in general practice, electrogalvanizing layer is generally thin, resulting in poor anticorrosion and rust prevention effect than hot galvanizing, shorter protection life, poor scratch prevention effect, but relatively low cost, bright appearance than hot galvanizing.
