Houston PolyTank
DVS 2205 extrusion-wound HDLPE and polypropylene tanks. German engineering, American manufacturing, monolithic integrity — engineered for zero specification failure.
Houston PolyTank builds DVS 2205 extrusion-wound tanks in HDLPE and polypropylene, with a monolithic wall and a ductile, detectable failure mode rather than a layered laminate. Its patented rectangular tank fits standard 40-foot high-cube shipping containers. MagnaPlast manholes are its own product line. HDPE is rated to 120F and PP to 180F chemical service.
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.
