Overview
Precast concrete pipes (with/without reinforcement) are used for sewers, culverts, storm drains and irrigation. BIS (ISI) certification assures conformity to Indian Standards on materials, dimensions, strength and durability—vital for public works and private infrastructure.
A BIS license enables lawful sale in India, increases acceptance in government tenders, and builds trust with EPCs and contractors.
