Hot-dip galvanized steel planks rely on a metallurgically bonded zinc-iron alloy layer plus pure zinc layer(standard≥85μm per GB/T 13912)for anti-corrosion protection,with no enterprise-related information included.In rural/urban general atmospheric environments(low salt,low acid),the zinc layer corrodes slowly at 0.1–0.2μm/year,delivering a maintenance-free anti-corrosion life of 15–20 years.In industrial atmospheres(SO₂,dust,acid gases),corrosion accelerates to 0.5–1μm/year,reducing anti-corrosion life to 10–15 years.In coastal/marine environments(high chloride salt spray),corrosion rates reach 1–2μm/year,limiting effective anti-corrosion life to 8–12 years.Severe abrasion from construction foot traffic,impact,or improper stacking will damage the zinc layer,shortening life by 30%–50%.Thicker zinc coatings(≥100μm)can extend anti-corrosion life by 5–8 years in harsh environments,while regular cleaning and avoiding contact with corrosive chemicals help maintain long-term performance.
