About Plastic Manhole Covers & Manholes
When Plastic Makes Sense
Plastic covers are the lightest and most affordable option for installations that don’t bear vehicle loads. They won’t corrode, won’t rust, and can be handled by a single person without lifting equipment. Ideal for monitoring well surface completions, landscaped utility access points, and any location where the cover is protected from traffic.
Plastic vs. Composite vs. Cast Iron
Plastic — Lightest weight, lowest cost. For non-traffic, protected areas only.
Composite — Heavier duty with UV stabilization and better structural properties. For outdoor exposed installations.
Cast Iron — Load-bearing for roadways and vehicle traffic.
