MANHOLE COVERS
EN124 D400 Ductile Iron Manhole Covers: A Practical Buyer’s Guide for Infrastructure Projects
What should infrastructure buyers check in an EN124 D400 manhole cover?
Check the tested load class, material, clear opening, frame dimensions, cover-frame fit, locking or hinge options, coating and inspection documentation.
Is a D400 marking alone enough for procurement approval?
No. Buyers should review drawings, dimensions, material information, test evidence, product marking and the installation requirements for the specific project.
