Behlen 11' Classic Bunk Feeder | Metal Frame with Poly Trough

⚠️ LOCAL PICKUP ONLY — Available at Purity Feed in Kamloops & Merritt, BC. Contact us for pricing and availability.

Metal troughs rust. They pit, they corrode, they hold bacteria in the pits, and eventually they need to be replaced. The Behlen Country Classic Feed Bunk solves that problem at the trough level by pairing a heavy-duty 16-gauge tubular steel frame with a one-piece polyethylene trough that simply cannot rust. The poly trough is smooth, non-porous, and easy to clean — no rust, no pitting, no rough surfaces for feed and bacteria to accumulate. At 11 feet long with square ends that bolt directly to adjacent units, you can run as many bunks end-to-end as your operation requires. Green powder-coated frame, five 2-inch support straps holding the trough in place, and all-welded smooth construction with no sharp edges for livestock safety.

Key Features

• One-Piece Poly Trough – Polyethylene trough is corrosion-free, rust-proof, non-porous, and easy to clean — outlasts traditional metal troughs in outdoor farm environments
• 16-Gauge Tubular Steel Frame – Heavy-duty frame provides exceptional structural strength and resists the daily pushing and leaning pressure of cattle and horses
• 11-Foot Length – Accommodates multiple animals feeding simultaneously — longer than a standard 10-foot bunk for operations that need more feeding space per unit
• Expandable System – Square ends allow multiple bunks to be bolted directly together end-to-end, building a continuous feeding line of any length for larger herds
• Five 2" Support Straps – Five heavy-duty straps secure the poly trough to the steel frame, keeping it firmly in place under livestock pressure
• All-Welded Smooth Construction – No sharp edges or exposed hardware — safe for livestock contact during feeding
• Green Powder-Coat Finish – Weather-resistant coating on the steel frame holds up to Canadian outdoor conditions year-round

Ideal For

Cattle, horse, and mixed livestock operations looking for a rust-proof, long-lasting bunk feeder, farms that need an expandable feeding system that can grow with the herd, producers replacing corroded or pitted metal troughs with a maintenance-free poly alternative, and operations in high-moisture or high-rainfall environments where metal trough corrosion is an ongoing problem.

Frequently Asked Questions

What is a poly trough and why is it better than a metal trough for a bunk feeder?
A poly trough is made from polyethylene — a dense, food-safe plastic that is completely corrosion-free and rust-proof. Metal troughs, even galvanized or powder-coated ones, will eventually rust and pit when exposed to moisture, manure, urine, and feed acids over time. Once a metal trough pits, the rough surface harbors bacteria and is difficult to clean properly. A poly trough has a smooth, non-porous surface that stays clean, doesn’t rust, and doesn’t pit — making it the preferred choice for operations focused on feed hygiene and long-term durability.

What is the expandable system and how does it work?
The Behlen Classic Feed Bunk has square ends — meaning the ends of the feeder are flat and perpendicular, not angled or rounded. This allows multiple units to be bolted directly together end-to-end, creating a continuous feeding line of any length. If you need 22 feet of bunk space, bolt two units together. If you need 33 feet, bolt three together. This modular approach lets you start with one unit and expand as your herd grows, without needing to replace your existing feeders.

How many animals can feed from an 11-foot bunk feeder?
As a general rule, allow 18–24 inches of bunk space per mature cow or horse for grain feeding, and 12–18 inches for supplement or free-choice feeding. An 11-foot (132-inch) bunk feeder can comfortably accommodate 5–7 mature cattle or horses for grain feeding, or up to 7–11 animals for supplement or free-choice access. For larger herds, bolt multiple units together using the square-end expandable system. Contact Purity Feed for help sizing your feeding setup.

What is the difference between the Behlen Classic Feed Bunk and the Behlen Stockman Elite Bunk Feeder?
The key difference is the trough material. The Classic Feed Bunk uses a one-piece poly (polyethylene) trough that is completely rust-proof and corrosion-free. The Stockman Elite uses a deep 10-inch steel trough with a red powder-coat finish. The Classic is 11 feet long; the Stockman Elite is 10 feet. Both use heavy-duty steel frames. If rust-free, low-maintenance feeding is the priority, the Classic Feed Bunk with poly trough is the better choice. If a deeper steel trough and the Stockman Elite’s reinforced bracing are preferred, the Stockman Elite is the right option. Contact Purity Feed for help choosing between the two.

What can I feed in a bunk feeder?
Bunk feeders are suitable for grain (barley, oats, corn), pelleted supplements and minerals, silage and haylage, chopped hay, and total mixed rations (TMR). They are not designed to hold round bales — for round bale feeding, see the Behlen Eco Smart, Hayguard, or OTB8 round bale feeders available at Purity Feed.

How do I clean a poly trough?
The smooth, non-porous surface of the poly trough makes cleaning straightforward — rinse with water, scrub with a brush if needed, and allow to dry. Unlike metal troughs, there are no rust spots or pits to trap feed residue or bacteria. For thorough sanitation between feed types or after illness in the herd, the poly surface can be cleaned with a diluted bleach solution and rinsed thoroughly.
