When selecting materials for your irrigation system, you face one of the most critical decisions for your farm. The wrong choice can cost thousands in repairs, pipe replacement, and lost yields. In this article, we explain in detail why aluminum is the superior choice compared to steel and PVC.
Corrosion Resistance - The Key Advantage
When aluminum is exposed to air or water, an extremely thin but incredibly resilient layer of aluminum oxide forms on its surface. This natural protective barrier prevents further moisture penetration into the metal, virtually eliminating corrosion. The result? Aluminum pipes have a lifespan of 50+ years without any protective coating or treatment required.
By comparison, uncoated steel pipes begin to rust after first contact with water. Even galvanized steel pipes lose their protective layer after 10-15 years and must be replaced. PVC pipes don't rust but degrade under UV radiation and become brittle below -10 degrees Celsius.
Weight and Portability - The Practical Advantage
An IRRIGO 90mm aluminum pipe weighs just 7.12 kg, while an equivalent steel pipe of the same size weighs 15-20 kg. This difference is enormous in practice: one worker can carry an aluminum pipe, while steel requires two. On a 10-hectare farm with hundreds of pipes, this means half the labor for installation and relocation.
For portable sprinkler irrigation systems - where pipes are assembled and disassembled multiple times per season - aluminum's light weight is invaluable. Farms using aluminum pipes report 40-50% faster assembly compared to steel systems.
Thermal Conductivity
Aluminum has better thermal conductivity than steel, meaning water in the pipes adjusts to ambient temperature faster. This reduces thermal shock to plants - suddenly cold water from deep wells can damage the roots of sensitive crops.
Environmental Impact
Aluminum is 100% recyclable without quality loss. At the end of its long service life, your pipes retain significant scrap value. PVC is practically non-recyclable and pollutes the environment, while steel loses quality with each recycling cycle.
Cost Analysis - Best Value Long-Term
At first glance, aluminum pipes are more expensive than steel. But factoring in lifespan (50+ years vs 10-15 for steel), maintenance (zero for aluminum vs regular painting for steel), and end-of-life recycling value - aluminum is by far the most economical choice.
IRRIGO offers aluminum pipes at prices up to 33% lower than leading European brands like Perrot and RAESA. For example, our 90mm pipe costs approximately $90, while the Perrot 89mm costs $134.90. Equal or better specification at a significantly lower price.
