Manhole Shutters

NTS offers a range of steel manhole shutters to form concrete surrounds to manhole rings from 675mm internal diameter to 2700mm internal diameter. Manufactured from 2mm flexible steel and supplied in 900mm and 1800mm lengths these shutters are designed to be both flexible and easily manoeuvrable whilst offering adequate ring stiffness. All shutter lengths are considered in modular panel form, thus minimising constructional difficulties and maximising flexibility.
