Outdoor stairs and landing repair and replace on multifamily.

[Jace Holt]

Hi everyone, I am looking for the best repair and replacement solution for outdoor metal stairs which have rusted and the connected concrete upper landings which have cracked and are falling apart. They are for the top 2 units on 4-plexes. On a different property, the units with concrete steps disintegrated and will soon need replaced as well so I'm not really wanting concrete steps unless they are more durable in some way. Any ideas? Material types? Costs? Suppliers? I need to replace at least 10 of them.
