TRENCHCOAT (Polymer Coated Steel)
TRENCHCOAT Heavy-Gauge Protective Film

CONTECH Corrugated Steel Pipe with TRENCHCOAT® heavy-gauge protective film offers long–term protection for storm drains and culverts. Even under harsh condi­tions, TRENCHCOAT protects against abrasion and corrosion to provide at least 100 years of service life within the environmental range of 5.0≤pH≤9.0 R≥1500 ohm/cm. Bonded to both the inside and outside of CONTECH’s galvanized corrugated steel pipe, the film serves as a protective barrier—resisting corrosion from acids, salts, and alkalis found in today’s storm sewers and culverts.
