Plastic or cast iron sunroof?

Let’s first go back to the question – “Why is a sewer hatch necessary?”
First of all, ensure road safety. Secondly, create access to the communication system and last for many years.

What is the advantage of polymer-sand hatches? Probably only because of their cheapness. Therefore, if your choice fell on a plastic hatch, then remember the expression: “The miser pays twice.”

Of course, in parks or in green areas, you can resort to installing polymer-sand hatches. But, as practice shows, an unpleasant circumstance can arise here too. After all, a pedestrian’s sharp heel can easily get stuck in such a lid, or at worst, the kids will break through the lid with a stone. Let’s keep silent about the quality of the installation.
Contractors who purchase plastic hatches do not think about safety; their direct desire is to save money.

The superiority of cast iron is obvious. Firstly, it will last a long 20-30 years. This will significantly save your budget compared to polymer-sand hatches, which at first glance seem many times cheaper. Secondly, they fulfill their intended purpose according to GOST.
