Egypt: Why site data beats theoretical assumptions in desert environments.
At @Orbis Terrarum, we have recently completed several corrosion studies in the Nile Valley, Egypt. On paper, the sites may be classified as low aggressiveness but, as often, the reality was different.
What makes desert environments so demanding?
- Temperature swings above 25°C between day and night, driving condensation cycles
- Seasonal winds carrying saline dust, chlorides, and abrasive particles
- Lack of rainfall, leading to continuous accumulation of contaminants
- High solar radiation, accelerating coating degradation
- Aggressive soils under the dunes
The result: what appears to be a low-corrosivity environment can compromise the project’s service life.
A corrosion study makes it possible to:
- Define the right galvanizing thickness or alternative coatings (ZM/ZAM/Organic coatings/Duplex systems/Concrete)
- Predict real performance over 25–30 years
- Avoid premature structural failures
- Protect project returns from the design stage
And this is not limited to Egypt. We see it across the Middle East, North Africa, and also in markets such as Chile, Peru, and Mexico.
The question is simple, are you designing with real site data or assumptions?
Because the cost of not knowing can be far higher than getting it right from the start.
If you are working on projects in complex environments, it is worth discussing.
