Glassfibre Reinforced Plastic (GRP) is a composite material or fiber-reinforced plastic made of a plastic reinforced by fine fibers made of glass. Like graphite-reinforced plastic, the composite material is commonly reffered to by the name of its reinforcing fibers (fiberglass). The plastic is most often polyester or vinylester, but other plastics, like epoxy (GRE), are also sometimes used. The glass is mostly in the form of chopped strand mat (CSM) but woven fabrics are also used.
As with many other composite materials (such as reinforced concrete), the two materials act together, each overcoming the deficits of the other, whereas the plastic resins are strong in compressive loading and relatively weak in tensile strength, the glass fibers are very strong in tension but have no strength against compression. By combining the two materials together, GRP becomes a material that resists well both compressive and tensile forces. The two materials may be used uniformly or the glass may be specifically placed in those portions of the structure that will be experience tensile loads.

The Special Feature of Hot Pressed GRP Sectional Water Tank
Glass fiber Reinforced Panel is molded under condition of high temperature and pressure to maintain the best endurance. Since using stainless steel for inside structure and HDG steel for outside it shows best performance against corrosion.
No corrosion from panels and prevent bacteria increasing by isolating outside light.
The joints are sealed with special sealing tape especially developed for water tank.
The heat insulation panel with 3 layers structured improves heat insulation effect. Protect water from dewdrops and minimizes temperature variation of the stored water.
GRP Sectional water tank panels size is changeless from the outside condition so assemble it accurately.
Various sized panels are available in a limited space for the best way. Easy to Assembly and Transporting. GRP Sectional panels make construction time shorter. Standardization panels make easier to move,carry in and transfer.

The heat insulation panel with 3 layer structure improves heat insulation effect. Protects water condensation on the outside of the tank and minimizes temperature variation of the stored water.
GRP panels protect water condensation in the tank and minimizes temperature variation of the stored water to prevent dewdrops phenomenon.
Heat insulation cover with cloth attached inside can keep the heat of water and never off from the cover.so it can maintain its original shape for a long term.
It is possible to eliminate unusable space, and utilize the maximum space, by installing a partition type tank. Economical and effective for maintenance.
In the basement or other confined areas, it is possible to eliminate unusable space, and utilize the maximum space, by installing a partition type tank.
If partition type tanks are installed, one section can be used for drinking water, and the other section for service water (EX, fire fighting).
It is convenient for maintenance, because two tanks can be installed as one unit.
The cost and installation of 1 partition tank is cheaper than 2 individual tanks.
If tanks for two different uses are needed in a confined area or boiler room, a 16 ton partition type tank can be installed to use half for drinking water, and half for service water.
If separate tanks are installed, however, you have to installed two tanks with a maximum of 6 tons, because you need to have 1 meter distance between tanks for maintenance and operating space.
Base Concrete Pad :-Customers are requested to make base concrete according to the designed specifications and the strength of the site. Anchor bolts are to be fixed by our agents. The required strength of the base concrete must be at least 180kg/*. The thickness of mortar on the base concrete must not exceed 20mm.
The Extent of Installation Work :- If the customer designates the size of sockets for plumbing, our agents will install the sockets. After the sockets are in place, the plumbing and heat insulation must be done by customers.
Installation Space :-It is recommended to leave a space of 600mm in each direction from the tank for maintenance
Transportation :-Do not place heavy loads or force on the panels during the transportation. Those parts that are touched with rope or either cargo must be cushioned
Pipe Installation :-Be careful not to put any heavy weight on the pipes that are connected to the fitting. Pipe installation must be started from the water tank side and be careful not to put unbalanced weight on the fitting. Take precautions to avoid fire or other occurrences/accidents while welding.
Maintenance :-f it is not used for a long time, be sure to drain the water from the tank. As the tank is a reservoir of water for consumption by people, regular inspection should be done for safety (more than twice a year).
