Houston PolyTank
DVS 2205 extrusion-wound HDLPE and polypropylene tanks. German engineering, American manufacturing, monolithic integrity — engineered for zero specification failure.
What LibertyCES specifies from Houston PolyTank
Monolithic HDLPE and polypropylene construction with a ductile, detectable failure mode — not the layered laminate of FRP or the stressed-skin of roto-molded tanks.
Fits standard 40' high-cube shipping containers, cutting freight cost >80% and increasing storage capacity 20–30% vs. cylindrical tanks in the same footprint.

Frequently Asked Questions
What design standard do Houston PolyTank tanks follow?
DVS 2205, a German thermoplastic vessel design standard, engineered for creep control, thermal cycling, and 20+ year service life.
What is the difference between extrusion-wound and roto-molded tanks?
Extrusion-wound tanks have a monolithic, solid wall structure with a ductile (detectable) failure mode. Roto-molded tanks have a stressed skin with residual tension and fail by sudden stress cracking, typically lasting only 3–7 years vs. 20+ for extrusion-wound.
Is MagnaPlast a separate manufacturer from Houston PolyTank?
No — MagnaPlast is Houston PolyTank's own trademarked manhole and access product line, not an independently-branded company.
