Raising the goldfish need large area of water, but the depth should not too deep. The common narrow and deep type fish ponds are not suitable for raising the goldfish. The traditional pond has to be improved. The clay fish pot, also known as tiger basin, although it is good devices for goldfish, but its small volume of water, difficult to transport, and also it is not suitable for home decoration and supporting. Wooden fish pond can certainly do larger tanks, but because it is made of wood, it require regular maintenance, very un-convenience, and also not suitable for home usage. There are many of my friends using a linear polyethylene plastic pond, but it is itself a substitute product, mainly owing to drainage inconvenient, and its outdoor service life is too limited.

In domestic ornamental fish breeding is now generally using a new material tank—— fiberglass fish pond.

As our company’s fiberglass preformed fish ponds are completely in specification, so you can purchase it according to the required size, and thanks to the integrity of the fiberglass fish pond, the installed space only need slightly rearranged.

Goldfish need sunlight, so the outdoor and indoor moveable is particularly necessary, and fiberglass material’s stable physical properties that making its service life come to several decades. Professional sewage design and drainage design make the drained process several times faster, thus greatly reducing the intensity of labor (our bottom slope design fish pond is available). Moreover, the sizes of the fiberglass fish pond are variety to choose. The customers may find their ideal fiberglass fish tank whether to add the feet stool or pre-installation of insulation materials. Our fiberglass fish ponds are suitable for the different people’s actual needs. Some well-made special fiberglass fish tanks can be a perfect fitting of home decoration.

Of course, the fiberglass preformed fish pond also has its limited. The biggest shortness is its cost. And also we have to make molds before producing, and because of the small market, mold may not be too much, so the choice may be small.(Currently, our factory have 120 mould types) In addition, as the production of the fiberglass fish pond is mainly hand lay-up process, the production technical is also a key aspect.

2. In general, bigger fiberglass aquaculture tanks tend to be more stable, and it is best to shoot for at least 90- 100 gallons if you are growing edible fish to plate size.

3. You should stock your frp fish farming tank at our recommended “Rule of Thumb” of 1 pound of fish for every 5 – 10 gallons of water. An “average” amount of fish consumed per year according to the FAO is 37 pounds. A 200 gallon tank will produce about that each year.

4. You will want to have at least a 1:1 ratio of 12″ deep grow bed volume to fish tank volume. Much less than this will not provide adequate filtration for your fish. You can go all the way to a 3:1 grow bed : fish tank volume, but be sure to add a sump tank or two at that point so the water level in your fiberglass fish tank does not go too low during the flood cycle.

2.Lightweight, easy to move. For certain seasonal fish species, the frp hatchery tank is more convenient to changing the water and cleaning the inside. Meanwhile, the fish hatchery tank can also be used to transport the fresh water food or seafood. High impact strength, and loading and unloading very easy.

3.FRP fish farming tank is produced by the American standard resin, non-toxic and no precipitation. This resin is without any cytotoxicity effects.

4.Fiberglass material has good thermal insulation effect. When installed to fish farms in the cold winter, it will reduce the energy consumption which required for warming.

5.The frp aquaculture tank inherited the higher strength characteristic of plastic fish tank. Moreover, because of the characteristics of composite technology, it can be customized into different shapes. General the fiberglass aquaculture tank designed round type according to the pressure of the physical properties. There is intake pipe outlet in the center and the bottom which designed to pot shape. When used in fish farming, the inlet could design into whirlpool, so that the suspended solids will be concentrated in the tank’s pot shape bottom and whirlpool. The water filtration equipment will take bottom water first and filtering the suspensions maximized.

6.Compared with the traditional fish tank, fiberglass fish farming tank has little pollution to the water, and convenient to drainage, cleaning, disinfection, easily to move. It is more conducive to the growth of fish, could significantly increase the survival rate of fish.

Fiberglass Fish tanks typically are rectangular, circular, or oval in shape. Circular or oval tanks with central drains are somewhat easier to clean and circulate water through than rectangular ones.

Rectangular fish tanks are usually built with or set upon inclined floors to facilitate cleaning and circulation.

Rearing fish tanks range in size from 500 to 500,000 gallons capacity. The size of the tank depends on a variety of factors including: stocking rates, species selected, water supply,water quality, and economic considerations.

The fish tank must be designed to correspond with the capacity of other components of the system, particularly size of the biofilter and sump so that all parts of the system are synchronized.

Fish Tanks can be constructed of plastic, concrete, metal, wood, fiberglass, rubber and plastic sheeting, or any other materials that will hold water, not corrode, and are not toxic to fish.

Smooth surfaces on the inside of the tanks are recommended to prevent skin abrasions and infections to the fish, and to permit cleaning and sterilization.

Light weight, durable, fiberglass fish pond can be conveniently moved and readily cleaned when necessary, but they require special support to prevent stretching when filled with water.

Stainless steel also is a good tank material, but can be expensive. Marine-grade plywood tanks are inexpensive, but leak if not properly sealed and are not as durable as tanks of other materials.

Concrete tanks may be the most economical to build, but they are relatively permanent and immovable structures once constructed. Non-toxic plastic or rubber liners can but used over frames made of wood, metal, concrete, or other materials.

Fibre reinforced polymer (FRP) materials are being increasingly used in civil engineering applications due to their several advantages when compared to traditional materials, namely, the lightness, strength, good insulation properties, low maintenance and durability.

At the same time, new design issues and challenges are inevitably encountered, among which are the legitimate concerns regarding their performance when exposed to fire, especially in building applications.

Construction materials used in buildings are required to have adequate fire reaction behaviour, avoiding fire ignition, flame spreading and excessive smoke production and spreading. Additionally, structural elements are also expected to present sufficient fire resistance, in order to prevent structural collapse under fire.

However, when FRP materials are exposed to high temperatures (300–500 C), the organic matrix decomposes, releasing heat, smoke, soot and toxic volatiles. Also when heated to moderate temperatures (100–200 C), FRP materials often, creep and distort, and such degradation of the mechanical properties often leads to buckling failure mechanisms of load-bearing composite structures .

1.Introduction of FRP Pultruded Grating

FRP Pultruded Grating has most of the characteristics of molded FRP grating, but it also has some obvious different points. The most important one is high fiberglass content in load-carrying direction (65%-70%).So, compared with molded FRP grating, pultruded grating has obvious advantages on large stride distance. Because it can reduce the number of foundation support, reducing the cost. Excellent phthalate & isophthalic resin and surface veil mat is adopted, which make it possesses good corrosion property. 

2.Characteristics of FRP Pultruded Grating

• Light weight: Its weight is one quarter of steel gratings; easy for carrying, which reduce the carrying cost.
• Good mechanical property: Resin content is 35%; fiberglass content is 65%, which increase the rate between strength and weight.
• Aging resistance: UV absorption agent and polyester surface veil mat are added in the formula, which can protect from ultraviolet rays.
• Effective: The fire retardant effect is of 1 to 25, or oxygen index is above 26. Oxygen index can reach above 26. (per the requirement of project)
• Others: Impact resistance, free from maintenance, easy for processing, slide resistance, electric and thermal insulation.

3.Installation of FRP Pultruded Grating

1. Installation on FRP platform:

1) The width of support on steel beams of grating shall be at least 40mm, the gap between gratings shall be 6mm. The gap between grating and concrete column is 10mm.

2) The gap between grating and supporting steel beam shall be fixed by M or L shaped clamp. At least 4 clamps need to be used for one piece of grating. Two adjacent edges of useless gratings shall be connected by C shaped clamp. At least one clamp shall be used in the center of every 1.8m.

2. Installation in FRP handrail channels:

1) Adjust the size of channel refer to the size of each unit as possible as you can, which make the edge of grating after cutting to be the sealing face, ensure the integrity of units, and beautiful appearance.

2) 40mm support shall be added to the gratings on the concrete foundation; the gap between grating and concrete is 3-6mm.

3. Installation on FRP stairs:

1) The step of grating shall be in the step frame; the frame can be normal steel or FRP.

2) Gap between step and frame is 3-6mm; 4 fixing clamps are used for each step; 1 for one corner.

3) The types of the clamps supplied by our company are: M, L, and C. different type clamp has different functions: M type is used for the fixing connection between grating and supporting structure; L type is used for special limited connection between grating and supporting structure; C structure is used for connection between edge and edge of gratings. Corresponding bolts and gaskets are needed the connection.

4.Maintenance of FRP Pultruded Grating

1. Washing liquid can be used to clean the dust and dirties on the surface, no need of other maintenance measures.

2. Avoid direct connection with naked fire and high temperature, such as electric welding.

3. Avoid the drag and impact damage from any steel, steel sharp tools, and the painting pollution

There are a number of structural material to consider when engineering and designing a new structure, and Fiberglass Reinforced Polymers could be the right choice. These materials have outstanding properties that are better suited for a variety of environments.

FRP, or Fiberglass Reinforced Polymers, certainly aren’t new to the marketplace.

FRP’s have been around for many years, but it has taken some time for them to become universally accepted around the world, by Engineers, architects, and developers. FRP’s, for commercial use, have been extensively researched since the 1930’s, however, Engineers, architects, and developers, being unfamiliar with the material and uncertain as to which grade of FRP is the correct one, sometimes overlook FRP as a structural material.

Understanding FRP plastics and where they are best suited is important, and comes from an understanding of the products strengths and weaknesses.

There are many grades of FRP’s and not all of them can be used for the same application. Although all fiberglass products are not created equal, FRP products generally share these characteristics:

• Lightweight – Weighs 80% less than Steel
• Corrosion Resistant
• Low Conductivity – Thermally & Electrically
• Nonmagnetic – Electromagnetic Transparency
• High Strength
• Dimensional Stable
• Low Maintenance

The end result:

1) Fiberglass Reinforced Polymers becomes an excellent substitution for steel, aluminum, concrete or wood. In cases where the use of traditional products comes into question, such as situations where there may be rotting or corrosion, FRP products are often a much more sound choice. These FRP products typically last longer, are easier to maintain, and improve safety.

2) Significant cost savings are also a key benefactor when choosing FRP products. Not only because they have significant longevity and are virtually maintenance free, but also because the materials are lighter. The reduced weight decreases shipping costs and makes installation easier, which saves time during the construction phase.

As an example, in a wastewater treatment facility, FRP was used as an alternative to galvanized steel for handrails, ladders, and walkways; the installation was 50% faster due to the lightweight materials and ease of assembly.

Although they have many uses and applications, Fiberglass Reinforced Polymer products are typically available in two major product types; structural shapes, grating.

Structural Shapes

FRP Pultruded Structural shapes are produced in hundreds of shapes and are a strong, lightweight option for platforms, walkways, structures, floors, ladders, panels, decking, enclosures, handrails, and covers.
