Anticorrosion issues of the welded surfaces of galvanized flat steel
Thread Content
If galvanized flat sheets are laid in the soil, the welded surfaces need to be coated with asphalt for corrosion protection. When they are laid beneath a cement cushion layer (with a thickness of 15 centimeters), the welded surfaces cannot be protected against corrosion. According to civil engineering experts, applying corrosion protection under the cushion layer is not feasible, as it prevents effective bonding with the cement and can affect the strength of the cushion layer. What is the reasonable explanation for this? I would appreciate advice from civil engineering experts.
Let’s see if there’s anyone who can explain it so I can learn from it
If the flat steel you embed is poured into concrete, then no anti-corrosion treatment is needed, and this is also what civil engineering workers say. But if you bury it under a cushion layer, then anti-corrosion treatment is required, as it will corrode rapidly in the soil.
