Manhole step is designed for cleaning staff to move in and out of sewers safely and smoothly. It can be made of carbon steel,stainless steel, corrugated steel, ductile iron, cast iron, or aluminum. Coating could be polypropylene copolymer plastic,galvanized, black bitumen or epoxy coating. The coating can effectively protect manhole steps from corrosion and rust . Step also has bright color to ensure high visibility. In addition, it has high elongation capability, good loading pressure, high rigidity,high durability.
Constructed from a combination of polypropylene polymer and galvanized steel, these manhole steps offer superior strength and corrosion resistance, ensuring long-lasting reliability in even the harshest environments. The polypropylene coating provides a non-slip surface, improving worker safety when entering the manhole, while the galvanized steel core provides strong support and stability.
