Snyder Industries 300 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank

The Snyder Industries 300 Gallon Heavy Duty Vertical Storage Tank is built from crosslinked linear polyethylene (XLPE) molded to ASTM standards, in natural white resin, with dimensions of 51"H x 46"W x 46"L (a 46 x 46 inch footprint). The number that matters here is its 1.9 specific gravity rating: many vertical storage tanks are rated 1.0 to 1.5, fine for water but marginal for denser liquids, and this XLPE build carries the extra margin. If you are cross-shopping "300 gallon vertical tank" listings, that crosslinked wall is why Snyder rates this model for heavier-duty service than a comparable single-linear water tank — it resists stress-cracking and impact better than standard HDPE.

Will it work for your install?

At 300 gallons, a full charge of plain water weighs about 2,502 pounds, and the 1.9 SG rating supports contents up to roughly 4,754 pounds — that works out to about 15.8 lb per gallon, or liquids up to about 1.9x water density. Use that upper number, not the water figure, when you size your pad and anchoring. The 46 x 46 inch footprint is compact for the capacity, but a tank this heavy needs a level, continuously supported base so the load spreads evenly. If you are sizing a rural fire-suppression store, our guide on fire-water reservoir design and NFPA 22 sizing is worth a read; for general volume questions, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.

Why crosslinked resin here

The 1.9 SG rating is the honest headline on this model, and the XLPE wall is the reason it can carry that headroom. If you want the full trade-off between crosslinked and linear resin, our guide on Snyder XLPE vs HDPE walks through when crosslinking actually earns its keep. For above-ground installs, our concrete pad sizing framework covers building a base that carries the full rated load without cracking.

The mistake to avoid

Do not scale from the water weight when you engineer the foundation. A 300-gallon vertical that clears 4,700 pounds fully loaded will punch through an undersized or unlevel pad, and an out-of-plumb tank concentrates stress at the base knuckle. Size the pad to the 4,754-pound rated contents weight, not the water weight, and get the tank dead level before you fill it.
