GRP Tanks - One Piece

MP Tank Suppliers are high quality suppliers of one piece Glass Reinforced Plastic tanks. These are highly durable and strong cold water storage tanks for domestic, commercial and industrial applications. 

GRP tanks are a much better alternative to traditional tanks made from concrete and steel. GRP is a tested and proven material that requires little maintenance or operating costs, saving you money while meeting all your water storage needs.

Benefits of MP Tank Suppliers one piece GRP tanks

Our one piece tanks are made from high quality glass fibre that is impregnated with polyester resin. This provides maximum durability and strength. The tanks can also be used to store mild or even aggressive industrial chemicals when special resins are used. 

GRP tanks are additionally useful as feed and expansion tanks due to their ability to hold water at temperatures of up to 55C. For greater strength, the one piece tanks have treated timber reinforcements within the laminate, depending on the size of tank.

GRP tanks have several advantages including:

•Tough and resistant to shock, impact and tear and wear
•Require little maintenance over their lifetime
•Can withstand extreme temperatures
•Do not corrode or rust
•Hygienic and environmentally friendly 
•Lightweight and easy to install
•Can be used with normal fittings
