At a basic function, steps are installed inside manholes to allow safe entry and exit. Also known as rungs or ladders, manhole steps require strong materials like cast iron and galvanized steel.

However, once inside the manhole, the wall or barrel of the main cylinder can expand with a standard size of around four feet in diameter.

Manhole steps can come in various styles depending on the hole. The standard design for manhole steps tends to be vertical steps.
