Prefabricated stairs, as a key load-bearing structure connecting different floors or platforms, need to be in seawater immersion environment for a long time or periodically in some scenarios, and need to withstand seawater erosion, tidal load, wind and wave impact, and the impact of ships or floating objects. For example, in the maintenance passages of offshore wind power platforms, emergency evacuation stairs of coastal tide embankments, internal connecting passages of artificial reefs, prefabricated stairs are directly exposed to high-salinity seawater environment, and not only need to meet the requirements of conventional load-bearing performance, but also need to have excellent seawater corrosion resistance, impact toughness and structural stability under long-term alternating load.
