Product classification:

Trench cover

Key words:


High standards

Strictly implement the National Standard of the People's Republic of China "GB/T23858-2009 Inspection Manhole Cover" and the European Standard EN124: 1994 "Standard for Drainage Covers and Manhole Covers for Vehicles and Pedestrians".
