GRP Cylindrical Water Storage Tanks - Filament Wound

Extra co GRP cylindrical (filament wound) tanks can be used for underground or aboveground purpose and are designed to be assembled at factory.

The tank construction is as follows:

  • Shell: The Shell is produced by Filament Winding process
  • Tank ribs: The tanks construction shall include stiffener ribs to provide sufficient stiffness and rigidity to the tank. The rib forms shall be moulded GRP mechanically laminated over by machine to the tank shell.
  • End caps: The end caps are fabricated by hand lay-up application. Resin moulded or sprayed on precision-made steel moulds.
  • Assembly: The shell and end caps are then joined together by alternate layers of CSM and woven roving impregnated with resin.

GRP 'V' shaped water tanks

GRP 'V' shaped tanks are suitable for storage of potable water, they are manufactured by Hand layup process. Our standard mould sizes of these tanks are as below:-
