GRP Sewage / Sewer Pipe
H₂S-resistant GRP sewer pipe for sanitary sewage and stormwater.
For sanitary sewage and stormwater, GRP sewer pipe resists hydrogen sulfide corrosion that eats through concrete and metal. The corrosion barrier handles the aggressive inner atmosphere, while the ring-stiff wall takes trench loading — no coating, no cathodic protection, long service life in buried sewer lines.

Frequently Asked Questions
Why GRP sewer pipe instead of concrete?
Concrete sewer suffers H₂S / sulfuric acid attack; the GRP corrosion barrier resists the aggressive inner atmosphere with no coating.
What stiffness class do I need?
It depends on trench depth and backfill — tell us burial depth and soil, we design the stiffness.
