A-1 Tank defines why galvanized water tanks are built to last

–Water storage tanks are an investment, and durability matters as much as capacity. Whether a water storage tank serves agriculture, rural living, commercial needs, or fire suppression, it must last for years of day-to-day use and environmental pressures. A-1 Tank in Paso Robles has custom-manufactured galvanized water storage tanks since 1984 for residential, agricultural, commercial uses, and California and U.S. forestry.
Galvanized steel water tanks have earned a reputation for durability because they combine the strength of steel with a zinc coating designed to slow corrosion. Common materials for water storage tanks include:
- Galvanized steel is a strong, durable, corrosion-resistant material, made even more reliable with A-1 Tank’s seamless manufacturing method. Galvanized steel water tanks withstand damage from wildfires, snow, rainstorms, and tend to maintain their shape without warping or cracking during earthquakes. A-1 Tank’s optional epoxy inner coating is certified by the National Sanitation Foundation and complies with the ANSI/NSF Standard for potable water. The optional exterior coating is UV-resistant. Galvanized water tanks are suitable for Northern California and anywhere in the state.
- High-density polyethylene (HDPE) is lightweight, affordable, corrosion-resistant, and FDA-approved for potable water. Tanks are typically shaped via rotational molding. Repairs to damage may compromise the integrity of plastic-based tanks.
- Polypropylene (PP is a rigid plastic with high heat and chemical stability. Large sizes require reinforcement.
- Fiberglass tanks are rigid, lightweight, and are brittle, more expensive than plastic alternatives, and susceptible to algae growth. Fiberglass may not be repairable.
A-1 Tank manufactures galvanized water storage tanks to customers’ specifications, in capacities between 1000 and 20,000 gallons. The company serves all of California to the Oregon border and delivers anywhere within the state.
Galvanized water storage tanks also have a role in California’s defensible space law. Polyethylene, polypropylene, and fiberglass are vulnerable to wildfires. California requires that rural water storage tanks be accessible to firefighting crews. Local fire codes may require replacing fire-vulnerable water tanks in the 100-foot defensible space zone. Custom-built galvanized steel water storage tanks are the perfect solution.
Parts of California are known for rugged terrain, but that is no deterrent for A-1 Tank. With its custom-designed 4×4 vehicles, the company can deliver and install galvanized water tanks in Northern California’s rugged terrain and backcountry anywhere.
A galvanized water tank is often the stronger long-term choice when physical toughness, high capacity, corrosion resistance, and decades of outdoor service are the priority. The key is selecting a quality custom tank that meets specific design requirements for its job.
