Corrosion Resistance Standards in Coastal Zones

In high-humidity, marine environments like Douala or Libreville, atmospheric salt concentrations rapidly accelerate the oxidation of standard structural framing. For interior drywall profiles, standard light zinc coatings can degrade pre-maturely if exposed to continuous coastal air circulation during construction phases. Bati Profils structural lines counter this by utilizing hot-dip zinc coating layers engineered to resist micro-climate moisture pockets. The molecular bond formed during our roll-forming process ensures that even if minor surface scratches occur during installation, the surrounding zinc acts as a sacrificial anode, self-healing the exposed steel base and blocking the migration of deep rust channels down the metal frame.
