Characteristics of GRP:
HIGH RATIO OF MECHANICAL STRENGTH TO WEIGHT:
as GRP possesses a low relative density (from 1,6 - 1,9kg/dm) it is stronger than a steel structure at an equal weight.
FLEXIBILITY OF INSTALLATION:
possibility of use all methods used for installation of other materials.
HIGH CORROSION RESISTANCE:
GRP is made with materials that are intrinsically resistant to water, solvents, acids and basic chemicals LOW 
COEFFICIENT OF FRICTION:
the inner liner has a particularly smooth surface
EASY AND QUICK INSTALLATION:
with bell & spigot joint the installation is easy and very quick, the joints do not require any welding nor protections
REDUCED NEED FOR INSTALLATION:
GRP pipes are very light weight making easier the handling activities
NO MAINTENANCE:
GRP pipes require no maintenance nor inspection.
