Three materials dominate the irrigation pipe market: aluminum, steel, and PVC. Each has strengths and weaknesses. This article provides an objective comparison across all key categories.
1. Durability and Lifespan
Aluminum: 50+ Years
Natural oxide layer provides corrosion protection without treatment. Pipes installed 40+ years ago still function flawlessly.
Steel (Galvanized): 10-15 Years
Galvanization provides protection that wears over time. After 10-15 years, rust penetrates. Uncoated steel lasts only 3-5 years.
PVC: 15-25 Years
No rust, but UV degradation makes it brittle after 5-7 years in sunlight. Cracks below -10°C.
2. Weight (90mm Pipe, 6m Length)
- Aluminum (IRRIGO): 7.12 kg - one worker can handle it easily
- Steel: 15-20 kg - requires two workers
- PVC: 3-5 kg - lightest but most fragile
3. Environmental Resistance
Aluminum: Excellent against moisture, all temperatures, UV, mild pH variations. Only weakness: extremely acidic/alkaline water (pH below 4 or above 9).
Steel: Rusts in wet conditions, requires regular painting and maintenance. Difficult to work with in muddy conditions.
PVC: UV degradation, cold cracking, heat deformation. Not suitable for above-ground portable systems.
4. True Cost Over 30 Years
Per piece (90mm, 6m):
- Aluminum IRRIGO: ~$90
- Aluminum Perrot: ~$135
- Galvanized steel: ~$60-80
- PVC: ~$30-50
Over 30 years:
- Aluminum IRRIGO: $90 (one purchase, lasts 50+ years)
- Steel: $60-80 x 2-3 replacements = $120-240
- PVC: $30-50 x 2 replacements + labor = $100-200
Aluminum is the cheapest long-term option.
5. Recyclability
- Aluminum: 100% recyclable, retains full value. Old pipes can be sold as scrap.
- Steel: Recyclable with quality loss.
- PVC: Practically non-recyclable, ends up in landfill.
Conclusion
For professional irrigation, aluminum wins on every metric except initial price - and IRRIGO solves that with prices up to 33% lower than leading brands.
