6 Best Galvanized Water Troughs For Horses That Old Farmers Swear By

Walk onto any farm that’s been around for more than a generation, and you’ll likely see the same thing by the fence line: a silver-gray galvanized steel water trough. In an age of colorful poly tanks and automatic waterers, these metal mainstays feel like a relic. But there’s a reason seasoned farmers and horse owners still trust them over anything else.

Why Old-Timers Still Trust Galvanized Steel

Plastic tanks have their place, but steel is in another league for durability. A horse can lean, rub, or kick a steel trough, and it will just stand there. Do that to a plastic tank in the bitter cold of winter, and you might come back to a giant crack and a pasture full of ice.

Steel also has an edge in keeping water clean and cool. The zinc coating has natural properties that help slow down algae growth, meaning less scrubbing for you. On a hot summer day, the reflective surface and thermal properties of the metal keep water noticeably cooler than a dark plastic tank that soaks up the sun.

The real clincher for anyone with a practical mindset is repairability. A determined horse or a clumsy tractor bucket might put a dent or even a small puncture in a steel tank. With a simple patch kit, you can fix it and get another decade of use. A cracked poly tank is, more often than not, just a very large piece of trash.

Behlen Country: The Classic Round-End Workhorse

Behlen is the name you see on troughs that have been sitting in the same spot for fifty years. Their classic round-end stock tank is an icon for a reason. The rounded corners are a critical safety feature, eliminating sharp edges where a horse could get injured.

These tanks are built for the long haul. They use heavy-gauge G90 galvanized steel, which means a thicker coating of zinc for superior rust resistance. Look closer and you’ll see the details that matter: four-ply locked seams that are sealed for water-tightness and a heavy steel tube rolled into the top rim. This reinforcement prevents the sides from bowing under the pressure of hundreds of gallons of water.

You can find a Behlen tank for nearly any situation. They range from small 40-gallon troughs perfect for a single pony or a temporary stall to massive 400-gallon models that can serve a whole herd. It’s the go-to, no-nonsense choice that has proven itself over and over.

Tarter Oval Tanks for Multiple Horse Pastures

If Behlen is the classic, Tarter is the highly respected and innovative competitor. Their oval-shaped tanks are particularly brilliant for pastures with two or more horses. The elongated shape provides more drinking space along the sides, allowing multiple animals to drink comfortably at the same time.

This simple design change can significantly reduce squabbles at the water source. In a herd with a clear pecking order, a round tank can sometimes lead to a dominant horse guarding the water. An oval tank makes it harder for one horse to monopolize the whole trough, ensuring everyone gets a chance to drink peacefully.

Tarter tanks are built tough, using corrosion-resistant G90 steel and featuring the same kind of reinforced top rim you see on other premium brands. A major practical advantage many of their models have is a built-in drain plug. Anyone who has ever had to siphon or bucket out a 150-gallon tank for cleaning knows that a simple drain plug is worth its weight in gold.

CountyLine Tanks: Tractor Supply’s Reliable Pick

You don’t always need the most expensive option to get a quality product. CountyLine is Tractor Supply’s house brand, and it offers an incredible balance of affordability and reliability. For the hobby farmer who needs a solid, dependable trough without the premium price tag, this is often the smartest pick.

These tanks deliver the core benefits of galvanized steel—durability, cooler water, and algae resistance—at a price that’s hard to beat. They are readily available at stores across the country, so you can go see one for yourself and haul it home the same day. No waiting for special orders or freight shipping.

Is it built to the same heavy-duty standard as a top-tier brand like Hastings? Maybe not down to the last detail. The steel might be a slightly lighter gauge, but for most typical horse herds and hobby farm use, it is more than sufficient. It’s a workhorse that proves you can get 90% of the performance for a fraction of the cost.

Hastings Equity: Heavy-Duty for Tough Herds

When you have horses that view equipment as a personal challenge, you need to bring in the heavy artillery. Hastings Equity is the brand you turn to when standard-duty just won’t cut it. These tanks are engineered for the toughest conditions and the most destructive animals.

The difference is in the steel. Hastings often uses a heavier 20-gauge galvanized steel for the sides and bottom, making their tanks exceptionally resistant to dents and damage. They also feature robust seam sealants and extra reinforcements, designed to withstand the pressure of freezing ice and the abuse of large herds.

This level of quality comes at a price. A Hastings tank is an investment, and it’s likely overkill for a couple of calm backyard horses. But if you’re tired of replacing lesser tanks or you operate in an extreme climate, the "buy it once, buy it for life" philosophy makes Hastings a very wise long-term decision.

Behrens Steel Tubs for Soaking Hay or Foals

Not every water container on the farm needs to hold 100 gallons. Behrens specializes in smaller, exceptionally well-made galvanized tubs that serve crucial, specific roles. Their round, seamless tubs are a must-have tool around any horse barn.

Their most common use is for soaking hay. For horses with metabolic issues, respiratory problems, or insulin resistance, soaking hay is a daily necessity. A 15-to-30-gallon Behrens tub is the perfect size—easy to fill, easy to dump, and tough enough to handle being moved around daily. The galvanized steel won’t break down from constant moisture like other materials might.

These smaller tubs are also fantastic for foals. A giant stock tank can be intimidating or even dangerous for a young foal. A shallow Behrens tub provides a safe, accessible water source for them to learn from. Their versatility makes them indispensable for everything from foot soaks to carrying tools.

Tarter Poly-Lined: Rust Prevention Built In

The one Achilles’ heel of a traditional galvanized tank is eventual rust, especially if you use a tank de-icer in the winter. Tarter’s ArmorCoat poly-lined tank offers a clever solution, giving you the best of both worlds. It pairs the rigid strength of a steel frame with the rust-proof, inert nature of a plastic liner.

The design is simple: a tough galvanized steel exterior provides the structure and durability to withstand kicks and bumps. Inside, a seamless polyethylene liner holds the water, completely isolating it from the metal. This eliminates the risk of rust from the inside out and makes cleaning incredibly easy.

This hybrid approach is ideal for anyone in an area with highly corrosive mineral-rich water or for those who rely heavily on tank de-icers, which can accelerate corrosion at the seams. While it costs more than a standard steel tank, it’s a smart upgrade for maximizing the trough’s lifespan and ensuring water purity.

Keeping Your Galvanized Trough Clean and Safe

A trough is only as good as the water in it. Regular cleaning is non-negotiable for your horses’ health. The good news is that galvanized steel is easy to scrub down with a stiff-bristled brush (avoid wire brushes, as they can scratch the protective zinc coating). A splash of apple cider vinegar in the water can help manage algae between bigger cleanings.

If you have a drain plug, use it. Tipping a large tank is a back-breaking job that often gets put off. A drain makes a weekly scrub-down a quick, simple chore. Just drain, scrub the sides, rinse, and refill.

Safety around a steel trough is critical, especially in winter. If you use a tank de-icer, it must be one specifically designed and rated for use in a metal tank. Using a de-icer meant for plastic tanks can create a stray voltage situation, effectively electrifying the water and turning your trough into a serious hazard. Always check the top rim for any sharp edges that might develop from wear and tear and file them down if needed.

Choosing a water trough isn’t just about holding water; it’s about investing in a piece of equipment that will serve your horses safely and reliably for years to come. While modern materials have their appeal, the time-tested strength and practicality of galvanized steel are why it remains the foundation of a well-managed farm. Pick the right one, take care of it, and it will likely be the last one you’ll ever need to buy.
