Aquaculture and Tanks

We manufacture tanks that are durable, rust-free and easy to move. They come in various sizes and with several extra features and offer optimal durability, low weight, and corrosion resistance.

Aquaculture

We manufacture many kinds of specialty tanks. In the past, we have produced swimming pools, spas, fish ponds, aquarium tanks, hazardous waste containers and a wide variety of aquaculture products. We can help you engineer and structure a single tank or a system of tanks, meeting your design needs and specifications.

Our tanks can be customized in many ways including: adding slots for screens, location of inlets, drains, standpipes, fish evacuation openings, and tank-to-tank connecting channels with gate valves. With gel-coating on all surfaces, our tanks are very low-maintenance and require no painting.

In addition to our aquaculture products, we have manufactured swimming pools, spas, fish ponds, aquarium tanks and hazardous waste containers. C.F. Maier Composites aquaculture tanks will save time and costs, as they do not need to be replaced every few years due to corrosion.

Fiberglass Stock Tank

Stock Tanks

Our NRCS-approved stock tanks are durable, rust-free and easy to move. They come in various sizes and with several extra features. Our clients choose fiberglass stock tanks because of their durability, low weight, and corrosion resistance.

The tanks are gelcoated for UV protection, which saves time and money since they never need to be replaced due to corrosion; the estimated lifetime is over 20 years. Fiberglass stock tanks require minimal maintenance, and they are easy to relocate.

Our tanks feature a 2” overflow drain and they have an anti-slip bottom. We offer a large selection of plumbing fittings and we also have float boxes available. Our larger tanks (12’, 16’, 22’) come in two pieces and can be assembled on-site in less than 4 hours.

We meet the requirements of the NRCS Cost Sharing Program (Soil Conservation Service), code 614 (Watering Facility), for several states.

Fiberglass Stock Tank Advantages

  • The most notable advantage that fiberglass stock tanks offer to livestock is its high resistance to corrosion – meaning, the tanks will not rust.
  • Corrosion resistance allows installation directly on any kind of soil.
  • Fiberglass products are perfectly suited for outdoor use because they are made to handle extreme weather changes all year long.
  • The production process requires that fiberglass goods are manufactured for high stress and high impact use. This makes fiberglass stock tanks highly durable; the wall thickness is at least ¼ inch.
  • Fiberglass stock tanks require minimal maintenance and are also very easy to reposition.

Round Culture Tanks

The round fish culture tanks come in various sizes, in a sectional or one-piece design, and are available with or without skirting. These tanks have a reinforced top lip and are gelcoated on both the inside and outside surfaces. The walls are slightly tapered to allow nesting together for economical shipping.

Rectangular Fish Rearing Troughs

These free-standing tanks are constructed of either fiberglass with balsa wood laminates or fiberglass with steel laminates. It is easy to walk and easy to work between these tanks, as there is no external bracing required. Where space requirements are less demanding, our economical all-fiberglass tanks with bracing offer exceptional rigidity and strength.
